1 Functionality and Operating Concept

1.1 Functionality of the P4

The following graphic gives you a rough overview of the functionality of the ProfiLux 4

Aquarium Controller. It also shows the interaction of the different system components.

EN 2017-02-06 7

ProfiLux 4 Programming Guide

DANGER

Please note the following:

 The ProfiLux 4 Controller and its components (ProfiLux 4 System)

perform measurement, control, and control tasks based on your settings.

 There is no plausibility check of the settings you have made.  The controller's factory settings must be adapted to the

requirements of your aquarium.

 You are solely responsible for the plausibility of your computer

settings and its system components.

 The ProfiLux 4 Controller cannot replace the lack of expertise

required for the maintenance and maintenance of an aquarium or terrarium.

 Never leave your aquarium unsupervised for an extended amount of

time.

 The ProfiLux System can help you with a large number of tasks and

display error conditions - but it cannot replace regular personal supervision and control.

 The maximum period of time without personal supervision depends

on how long your aquarium / terrarium can survive even in the event of a fault without significant damage.

 Always remember that technologies can fail and therefore,

malfunctions can never be ruled out! Power failures, incorrect settings, damage (For example, by water or overvoltage) or simply an unexpected operating situation can lead to fatal damage.

 The manufacturer disclaims any liability for (consequential) damages

or losses which might arise in connection with the use of the ProfiLux System as legally permissible.

EN 2017-02-06 8

ProfiLux 4 Programming Guide

The diagram shows an example of the functionality of the ProfiLux System.

Sensors that are used for measuring various values such as Temperature, humidity, etc., are

connected to either the ProfiLux 4 or to corresponding ProfiLux Expansion Cards. Each of these

sensors are assigned to a control circuit where parameters such as Set-point, hysteresis,

nocturnal change, etc., can be set.

With the desired values and settings set, each sensor can then be assigned to control a

powerbar socket. For example, assigning a temperature sensor to a powerbar socket will

result in that socket switching on/off based on the set probe conditions.

EN 2017-02-06 9

ProfiLux 4 Programming Guide

TIP

When creating a command, it is useful to set the function first.

1.2 Operating Concept

The operating concept of the ProfiLux computer strictly differs between two sets of settings:

 Settings of functions such as e.g. pH set point, illumination run of a luminaire or

behavior of pumps

 Settings of hardware such as the behavior of a switch socket (if this switching socket is

assigned to a lighting, a timer or a temperature sensor) or the behavior of a 1-10 V interface (this interface should be assigned to a lighting or a pump)

This concept is extremely flexible because a function can be changed largely independently

of the hardware assigned to it and vice versa the hardware can be changed largely

independently of the function.

This concept allows you, e.g. to select a different socket for switching your tubular heater,

while the corresponding temperature settings can remain unchanged.

1.3 Examples of Settings

For a better understanding, take a look at some setting examples that are commonly used.

1.3.1 How to setup Temperature control

1. Setting the function: Set the desired set-point temperature, see also Sensor Settings->

Nominal value.

2. Setting the hardware: Set the switch socket outlet (socket) to switch the heating

element, the substrate heater and the cooling system (if present). See also System-> Socket outlet function.

1.3.2 How to set the Illumination?

1. Setting the function: Set the illumination run as needed, see also Sensor Settings->

Nominal value.

2. Setting the hardware: Set which switch socket outlet (for non-dimmable luminaires),

also see under System-> Socket outlet function, or which 1 - 10 V interface (for dimmable luminaires), also see under System-> 1- 10 V interface, or whether the Mitras Lightbar interface (when controlling a Mitras Lightbar) shall respond to this illumination run.

EN 2017-02-06 10

ProfiLux 4 Programming Guide

1.3.3 How to set the Level control?

1. Setting the function: Set the operating mode and the behavior of the level sensor, also

see under Level-> Control.

2. Setting the hardware: Set which switch socket outlet (socket) is to be switched from

the level control, see also under System-> Socket outlet function.

1.3.4 How to set the Current pump control?

1. Setting the function: Set the pump groups and the current pumps, see also under

Extras-> Current.

2. Setting the hardware: Set which switch socket outlet (for non-speed-variable pumps),

see also System-> Socket outlet function, or which 1-10 V interface (for speed-variable pumps), and see also under System -> 1-10 V Interface should react to the Pump.

1.3.5 How to set Dosing or Timer activities?

1. Setting the function: First set the desired timer or dosing pump (note: only GHL Dosing

Pump Unit 1st generation, GHL Doser 2 is controlled via PAB!), see also under Clock-> Timers or under Clock-> Dosing pump.

2. Setting the hardware: Set which switch socket outlet (socket) is to be controlled by this

timer or dosing pump, see also under System-> Socket outlet function.

1.4 Features / Resources

The functional range of your ProfiLux 4 and, if applicable, your ProfiLux System is determined by the available Expansion Cards, sensors, PAB devices and LED lights. The total of all available inputs and outputs in the ProfiLux system is referred to as resources.

1.5 Numbering and Display of Resources

All resources of the system are serially numbered by the ProfiLux Controller and this is always

carried out the same way.

The resources of the ProfiLux are numbered firstly, followed by the respective PAB devices in

order of their assignment such as Power Bars, Expansion Boxes, etc.

The numbering always starts with the internal resources of the ProfiLux, followed by the

resources of the module cards in the expansion slots according to their order in the slots of

the ProfiLux.

Then the resources of the first found and assigned PAB device will follow, after that the

resources of the second PAB device, etc.

EN 2017-02-06 11

ProfiLux 4 Programming Guide

2 Clock

Use the clock feature to make changes to all time-related settings. ProfiLux 4 uses the

astronomical hour count which divides the day into 24 h.

Two clocks are running the ProfiLux 4.

The first clock is a so-called real-time clock (RTC). It shows the actual ("our") time. This is also

the time normally seen on the display. In the event of a power failure, this clock runs on a

battery-backup.

The second clock runs in the device (internal). This internal clock controls the automatic

processes such as dimming, nocturnal decrease, timers, etc.

By default, both clocks run in sync with each other, except when the actual time (e.g.,

automatic or manual winter time / summer time) is adjusted. Then the internal clock is not

adjusted immediately, but within the set days. For example, a setting of 10 days results in

60:10 = 6 minutes daily.

2.1 Time & Date, DCF

First you will be asked if you want to use DCF (external radio clock receiver, available as an

accessory).

If you confirm with Yes, the time received by the radio receiver is used. If the reception is

sufficient, the setting of the date and time is superfluous, they are updated automatically.

If you are not using DCF, you can now optimize the clock accuracy by entering a correction per

day (from -59 s to 59 s). At 0 s (default setting) the clock runs without correction, otherwise

the adjusted second number is added (or subtracted) once per day.

Then you have the option to determine whether the ProfiLux clock should change between

the normal time (CET) and the summer time (CEST).

If this shall not be the case, then in your aquarium only the normal time will be valid (i.e. in

summer the clock will go wrong by one hour). This makes possibly sense if you would like to

avoid the clock change for your fishes and plants.

If you want a changeover, you can still adjust how many days the changeover is to be made.

If you use DCF, this smooth time adaptation starts beginning from the time of the CET-CEST-

change. If you don’t use DCF, then the time can be changed manually by one hour.

EN 2017-02-06 12

ProfiLux 4 Programming Guide

Note

The DCF signal for the radio clock is not always present.

Therefore it could happen that sometimes no reception is possible.

The internal clock continues to run and is synchronized again at the next reception (possible minor deviations are corrected). Therefore DCF can also be used with only occasional reception.

In this case also, the internal clock will be adjusted slowly within the set days. With this, you

are given the opportunity to spread this one hour over several days and you will have a

smooth time change.

After this you can then set the date and time manually.

When you save the time settings, you will be asked if you want to update the internal time

(see above).

If you confirm with Yes, the internal time is immediately set to the new time, otherwise the

internal time will be adjusted smoothly as explained above.

For initial time setting you should confirm with Yes. If you want to change clock due to

summer time, confirm with No.

2.2 Reminders

ProfiLux 4 can remind you of activities to be performed.

After a certain adjustable time (in days), the reminder text is displayed on the ProfiLux 4,

alternating with the standard display.

The reminder is displayed until you mark it as done. If you have set a repeated reminder, the

reminder will be displayed again after the new expiration time.

For example, a reminder can be set to be displayed every month to indicate a filter must be

replaced.

A single and repeating reminder can be set to display the desired text when requested.

After setting the reminder(s), ProfiLux 4 will display as a confirmation when the next reminder

will come about.

You can enter up to 16 reminder texts.

EN 2017-02-06 13

ProfiLux 4 Programming Guide

NOTE

You can use a timer for dosing purposes, but for more sophisticated functions, we recommend using the dosing pump control, see

Clock ->Dosing pump.

 Select the reminder (1 - 16) first.  Select whether the reminder should be enabled -> RETURN  If this reminder is currently up-to-date, you can mark it as done, it will not be

displayed any further.

 If you have activated this reminder with Yes, you can set whether you want to be

reminded repeatedly.

 You can then enter how many days you want to be reminded.  Then enter the reminder text.

Press the top arrow button on the control panel. The letter A appears. Press again to

display the letter B, press again to display C, and so on. The letters appear according

to their order in the alphabet. If you want to go back a letter (for example from C to B),

press the lower arrow key.

Press the left and right arrow keys to move the cursor to the right and left, and enter

additional characters or spaces.

When the text is finished, press RETURN and press YES. Safe with -> RETURN

After saving, ProfiLux 4 shows a confirmation when the next reminder is pending.

2.3 Timers

ProfiLux 4 has 32 freely programmable timers whose function you can adjust as described

below. The switch socket outlets (hardware), which are to react to the switching operations,

can be assigned as described under System-> Socket outlet function.

After selecting the timer that you want to program, the switching mode (function) needs to

be set. The following options can be selected:

Normal

This mode is used to program longer switching times (accuracy 1 minute).

The switching time (Duration) is set by entering the switch-on time and the switch-off time.

With this setting, short switching times (1s to 300s, accuracy 1s) can be realized. The

switching time is set by entering the switch-on time and duration.

Automatic dosing

As many Dosings per day will take place as it has been set before under Switching cycles per

day. The time points of the dosings are calculated automatically (they are spread evenly

throughout the day). The switching duration is calculated automatically on the basis of the

Flow rate of the pump and the Rate per dosing (see below).

Manual dosing

As many Dosings per day will take place as it has been set before under Switching cycles per

day. The time points of the dosings can be defined explicitly afterwards. The switching

duration is calculated automatically on the basis of the Flow rate of the pump and the Rate per

dosing (see below).

Event start

The timer initiates an operation such as e.g. A water change, see also under ->Level. Enter the

start time only.

Cyclic

This mode allows very special switching sequences. Please note that this mode can only be

selected and set via our PC program GCC (GHL Control Center)!

In this mode, the timer is switched on and off alternately, always after a certain waiting time

has elapsed.

The wait time after which is switched on is determined by random generator within the limits

of the minimum waiting time and maximum waiting time. If the waiting time should always be

the same, enter the same value for both times. The waiting time after which is switched off is

also determined by a minimum waiting time and a maximum waiting time.

One cycle consists of 1 to 4 pairs of switch-on and switch-off waiting times. After the last

switch-off of the cycle, the cycle starts from the beginning. All waiting times are adjustable in

the range from 1 s to 65535 s.

Example for a cycle with 2 switch-ons and switch-offs:

Instructions for Dosing

The dosing amount per day corresponds to the Dosings/day and Rate/Dose. For example, 4 doses per day with 10ml per dose will result in 40ml being dosed per day.

Alternatively, you can also use a timer or a controller (e.g. pH-value or conductivity) to control a dosing pump.

Due to tolerances, a pump’s flow rate on the data sheet can deviate from the reality. To achieve the highest possible level of dosing accuracy, we recommend you measure the actual flow rate of a pump (let pump run for 1 minute and measure the quantity of fluid pumped in this time) and set the result of this measurement in Flow rate.

After that, you can enter the number of Switching cycles per day (0 up to 8; 0 means that this

timer is not active)

After setting the switching cycles, enter the Day mode:

Days of week

Here you can set the weekdays to be switched. A marked box means "Switching active on this

weekday", an empty box means "inactive ".

Interval of days

Here, the number of days after which the switching cycle is to be repeated is set, 1 day

means a daily switching cycle. After that you can set in how many days the switching shall be

started.

If you have selected a dosing switching mode, you must also enter the flow rate in ml /

minute.

Here, the actual pump power is needed. Based on this information, ProfiLux 4 calculates the

switch-on times of the dosing pump.

Changing this setting does not affect the pump performance - this is predefined by the pump

mechanism!

For an automatic dosing, you must also adjust the Rate per dosing.

A timer can activate a feeding pause, see at Extras-> Feeding pause.

EN 2017-02-06 16

ProfiLux 4 Programming Guide

2.4 Dosing Pump

ProfiLux 4 has 16 freely programmable dosing pump controllers, whose function you can

adjust as described below. The switching outputs (hardware) which shall react to the

switching processes can be assigned as described under System-> Socket outlet function.

Select the dosing pump you want to program and then set the Switching mode. Choose from

the following options:

1. Automatic dosing: This mode is suitable if you want to dose a certain amount of the

same quantity evenly over a certain time. A maximum of 150 doses per day are

possible

2. Manual dosing: This mode is suitable if you want to dose a certain amount at fixed

times during the day. For example, at 8:00 o'clock, dose 35 ml of XY. A maximum of 8

doses per day are possible.

Furthermore, you can determine whether you want to dose on specific weekdays or daily

intervals.

Day modes:

Days of week

Here, you can set the weekdays at which the switching should be carried out. Use the right

arrow key to select the checkboxes, to move on downwards press arrow down. A marked box

means "Switching on this day of week active", an empty box means "inactive". Confirm the

selection with ->RETURN.

Interval of days

Here, you can set the number of days by which the switching cycle/number of dosages are to

be repeated. 1 day means daily dosage. The maximum daily interval is 200 days. Be sure to

set the number of days until the switching/dosing shall start.

After that, enter the Flowrate of the Pump in ml/minute. Based on this information, ProfiLux 4

calculates the switch-on times of the dosing pump.

Changing this setting does not affect the pump performance - this is predefined by the pump

mechanism!

Automatic dosing

 Set the number of doses per day. Use the arrow keys on the control panel to move the

cursor to the right or left. Enter numbers using the upper arrow key (counts up). Use

ProfiLux 4 Programming Guide

the lower arrow key to count back. Once you have entered the desired number,

confirm with ->RETURN. Up to 150 dosages are possible, 0 = No dosage.

 Decide on which weekdays the dosages should take place or select the daily interval if

a dosing is to take place every day or every 2 days ... etc.

 Enter the Flow rate of the dosing pump ->RETURN  Enter the dosing amount Rate per dosing ->RETURN

The dosing time points are calculated automatically (they are distributed evenly throughout

the day). The duration of the dosage is calculated automatically by means of the Flow rate of

the pump and the Rate per dosing (See below).

Manual dosing

 Set the number of doses per day. A maximum of 8 dosings per day are possible -

>RETURN

 Decide on which Days of week the dosages should take place or select the Interval of

days if a dosing is to take place every day or every 2 days ... etc. The maximum daily

interval is 200 days (see below).

 Enter the flow rate of the dosing pump ->RETURN  Specify the time at which the first switching / dosing should take place  Enter the dosing amount Rate per dosing ->RETURN  Proceed with the further desired switching operations as with switching operation 1

There are as many switching cycles per day as was set at dosages per day before. The time

points of the dosage can be defined explicitly in the following. The switching time is

calculated automatically by means of the Flow rate of the pump and the Rate per dosing. (see

below).

If you have selected Automatic dosing, the first dosing of the day is usually made at 0:00. With

Always dose at (this time) you have the possibility to determine the time of the first dosing. All

other doses are distributed throughout the day

The following features are only available via GHL Control Center, Web Interface, App and cloud

service myGHL:

The dosing pump control has a level monitoring. When the pump is active ProfiLux 4

calculates the new filling level.

For this purpose, the Capacity of the container as well as the minimum amount must be

entered.

EN 2017-02-06 18

ProfiLux 4 Programming Guide

Instructions for Dosing

The dosing amount per day corresponds to the Dosings/day and Rate/Dose. For example, 4 doses per day with 10ml per dose will result in 40ml being dosed per day.

Alternatively, you can also use a timer or a controller (e.g. pH-value or conductivity) to control a dosing pump.

If Alarm when below is activated ProfiLux 4 outputs an alarm. Before an alarm is issued

ProfiLux 4 will give a warning.

If the container is refilled, the replenished quantity can be entered, a possible alarm will be

reset if there is sufficient refilling.

2.5 Location

The coordinates (Longitude and Latitude) of your location can be entered here. This

information will be used for further simulations in the future.

From the factory, this is 49.4 ° N and 7.8 ° E - the coordinates of Kaiserslautern in Germany -

the production location of your ProfiLux 4.

3 Illumination

This menu contains all lighting-related settings and functions.

ProfiLux 4 can control 32 dimmable or non-dimmable lamps independently. Lighting units

can be switched via our powerbars. Dimmable lighting units can be also controlled via the 1-

10V interfaces. The dimmable LED Mitras Lightbar is controlled via its own digital interface.

Dimmable tubular lightbars are controlled by L1 (or L3, L5, etc.) as standard. It controls both

tubes of that lightbar.

You also have the option to simultaneously dim tubular lightbars.

EN 2017-02-06 19

ProfiLux 4 Programming Guide

TIP

If required, you can retrofit additional 1-10 V interfaces with ProfiLux Expansion Cards, PLM-4L or PLM 2L4S.

NOTE

The brightness curve between the individual dim-points are calculated automatically.

You can set the illumination run for each lighting individually. This makes it possible to

achieve effects like sunrise or moonlight.

3.1 Illumination Run

Please select which lighting is to be edited (Illumination to edit?). After selecting a lighting, you

can set the type of the luminaire, dimmable and non-dimmable.

It is also necessary to specify whether the automatic is to be switched on (Automatic on?). If

this is not the case, this lighting is in manual mode. Select whether you want a temperature-

dependent light reduction.

Enter the number of dim-points (for dimmable luminaires) or the switch-times (for non-

dimmable luminaires) for which you want to adjust the brightness (up to 24)

If you have selected a dimmable luminaire, please set the following for each dim-point:

Time – At this time, the luminaire shall have the brightness to be set subsequently

Light intensity (0% - 100%) – Brightness of the light at this time

If you have selected a non-dimmable luminaire, please set the following for each dimming

time:

Switch on – The light is switched on at this time

Switch off – The light is switched off at this time

Then select which simulations should affect this lighting process and save the settings with

Yes ->RETURN.

EN 2017-02-06 20

ProfiLux 4 Programming Guide

TIP

To create/edit your Illumination run, we recommend using GCC Light Composer. Light Composer provides the quickest solution for creating your

own lighting schedule.

The Light Composer calculates the individual lighting channels by means of the desired brightness and color sequence over the day.

You can download that free of charge software on our homepage (Support- >Downloads) www.aquariumcomputer.com.

The following functions can only be set via GCC.

3.2 Copy an Illumination Run using GCC

With this function, you can spare yourself the time of having to enter the same illumination

run settings again and again, especially if several illumination channels shall do the same.

If you activate Copy illumination run, you still have to enter the illumination channel from

which the run shall be copied. The entry of an illumination run on which you are just working

is then not necessary anymore (resp. also not possible anymore). This illumination channel

follows exactly the illumination run of the channel from which you would like to copy,

potentially time-shifted when you use the following functions.

3.3 Time shift with GGC

This function is used to allow an illumination channel to follow its set course or darkening

during clouds in a time-delayed manner. The time shift can be set separately for the

illumination run and for clouds. The time shift also has an effect when the illumination run

has been copied.

3.3.1 Time shift during clouds

With this function, sliding clouds that pull over several luminaires are possible.

This time, adjustable from 0 s to 3.1 s in steps of 0.1 s, determines with which delay the

illumination channel should be darkened during a cloud. The brightening at the end of a

cloud is delayed by the same time. If you have several dimmable luminaires that can be

separately controlled, you can use this function to create even more realistic clouds.

This time indicates the delay with which this lighting channel should follow its (or copied)

lighting curve (adjustable between 0s and 1h). With this function, it’s possible to distribute

switching on (or dimming up) and switching off (or dimming down) to several luminaires.

If you want your luminaires to have the same illumination run, only a little bit time-delayed,

the following procedure is recommended.

This menu is mainly used for testing and diagnostic purposes. With the arrow keys left right,

you can select the lighting channel whose brightness you want to adjust, 4 channels are

displayed simultaneously. Use the up and down arrows to make the channel brighter or

darker.

The symbols displayed to the left and right of the selected channel have the following

meanings:

Save your settings and exit the manual brightness setting by selecting Esc.

EN 2017-02-06 23

ProfiLux 4 Programming Guide

3.5 Clouds

ProfiLux 4 can simulate passing clouds by using a random generator. When a cloud passes, all

of the involved luminaires temporarily become darker as the simulation goes through its

effect.

The maximal waiting time (0s - 100s) determines how long the time intervals between two

clouds should be (with 0s the cloud simulation is switched off). The random number

generator waits between 1s and the maximal waiting time until a new cloud is generated.

Furthermore, the minimal and maximal cloud duration as well as the maximal darkening (10% -

95%) are to be set. The random generator generates new clouds, taking these values into

account.

The cloud simulation also works with simultaneous lunar phase simulations and during a

dimming process.

Note that the cloud simulation must be active for the desired illumination channels, see also

-> Illumination run.

3.6 Moon

ProfiLux 4 simulates the moon phases depending on the date.

In reality, the lunar cycle is a very complex matter:

 Thus the distances vary from new moon to new moon. On average it is about 29.5

days.

 Likewise, the moonrise time as well as the distance to the earth differ respectively.  It is not the fact that at half-moon the moon has 50% of its brightness. We consider on

average about 25%.

Our lunar phase simulation does not aim to replicate these complex sequences in every

detail. For us, it was important to produce a repeating moonlight sequence which would

illuminate the aquarium somewhat differently day-to-day. We’ve implemented such features

to provide a certain rhythm which would largely be in harmony with nature.

Lunar phases created by the ProfiLux 4 are based on the calendar date so that full moon and

new moon phases always correspond to the actual (real) lunar phase with a deviation of one

day or less.

You can set the time when the lunar phase simulation is active. In order for the lunar phase

simulation to function, it must first be activated in the desired lighting channels.

EN 2017-02-06 24

ProfiLux 4 Programming Guide

With the lunar phase simulation enabled on the selected lighting channels, the following

happens within the set time: The brightness (given by the set illumination run) is multiplied

by the calculated moon phase brightness. The illumination run is therefore still taken into

account.

The result is for example, at half-moon (= 50% lunar phase, 25% lunar brightness) and a

brightness of 30% (given by the illumination run). A luminaire brightness of 25% * 30% =

7.5%.

Illumination channels, without activated moon phase are not affected and follow their

lighting curves as normal.

Outside of the set simulation time, no illumination is influenced by the lunar phase

simulation.

With this method, it is possible to normally operate a lighting channel during the day (outside

the set simulation time/no influence of the lunar phase) and in the evening with the moon

phase (within the set simulation time).

The start and end-time of the lunar phase simulation should be created so that the night

illumination interval of the assigning lighting is included.

If the illumination of a luminaire is for example, programmed to illuminate as moonlight

from 19:00 (7:00pm) to 7:00 (7:00am), moon phase simulations should also be set from 19:00

(7:00pm) to 7:00 (7:00am).

The lunar phase simulation can also be tied-in with other simulations.

3.7 Rainy Days

ProfiLux 4 allows the programming of "Rainy days". On a rainy day, the lighting intensity is

reduced by an adjustable value.

With this feature, you have the option to set the weekdays for which Rainy Days should be

enabled. Once the days have been selected, the darkening of the day has to be set (0% -

100%).

The Rainy days simulation also takes other simulations into account.

3.8 Burning-in

Fluorescent tubes must be burned in before they can be used for dimming. ProfiLux 4

provides a convenient way to automate the burn-in process.

EN 2017-02-06 25

ProfiLux 4 Programming Guide

After selecting the Illumination to which the tube to be burnt-in is connected, the burning in

period can be set between 0h and 100h.

This lighting is then only operated with 0% or 100% until the operating hours meter (see also

-> Operating hours) has reached the burn-in period for this lighting (all dim-settings from 1%

are automatically output as 100%).

At 0% the lamp will be still switched off - the burn-in is done step by step.

By default, the burn-in time is set to 0 h, so the burn-in is deactivated.

3.9 Operating hours

Each lighting channel includes its own operating hours meter, which continues to run when

the corresponding lighting is active (brightness greater than 0%).

This feature continuously tracks the length of time a light is in operation so you always know

how when it should be exchanged. It is especially useful for preventing performance

decreases due to bulbs aging.

The operating hours counter is also used by the burn-in program. The operating hours are

written cyclically every 1h into the non-volatile memory. This ensures that the operating

hours are maintained even in the event of a power failure.

After selecting the menu item Operating hours, please select the Illumination option. The

operating hours for this Illumination are then displayed.

After a few seconds or by pressing a key, you will be asked if you want to “reset the operating

hours meter?” A confirmation with Yes resets the operating hours counter to 0 h. Of course,

this should only be done when changing the light source.

3.10 Thunderstorms

ProfiLux 4 can simulate an authentic thunderstorm.

When a thunderstorm simulation is in-effect, a slow reduction of all illumination channels will

occur. As these channels become darker, the number of flashes will increase. After the

thunderstorm has reached its climax, the lighting is slowly brought back to normal strength,

the flashes become less frequent until finally the thunderstorm is over.

A thunderstorm can be started manually any number of times or automatically up to 4 times

per day. There is also an option to start a thunderstorm at random.

Set the thunderstorm parameters in the Storm menu:

EN 2017-02-06 26

ProfiLux 4 Programming Guide

NOTE

The signals necessary for a thunderstorm can only be generated from the onboard 1-10 V interfaces (L1 to L6) or from the Mitras Lightbar connector.

A "thunderstorm illumination" should therefore not be connected to possibly existing additional 1-10 V interfaces (for example expansion card PLM_2L4S)!

Darkening (0% - 100%) during a thunderstorm

Intensity (1 – 20) of the thunderstorm – Higher numbers, the more flashes are generated

Flash brightness (10% - 100%) – Determines the LED output power during a flash

Thunderstorm/Day – Number of automatically generated thunderstorms in a day (max. 4)

Weekdays – Only on these weekdays there is a thunderstorm

Start 1...4 – A thunderstorm begins at this time

Duration 1...4 – Duration of a thunderstorm (1 to 60 minutes)

Random thunderstorm duration – If you want random thunderstorms, enter a duration (max.

60 minutes) for the random thunderstorm (If you enter 0, randomly generated

thunderstorms are disabled).

Waiting time minimal and maximal – the random generator determines a waiting time within

these limits (maximum 240 hours) until the next random storm is started.

In the Thunderstorm menu, a thunderstorm could be manually started by selecting Manual

Start. The duration (1 to 60 minutes) must then be entered here. When a manual

thunderstorm is triggered, the stored thunderstorm intensity and darkening Settings are

used.

3.11 Temperature-dependent light reduction

With this function, it is possible to gradually reduce the lighting (in the case of dimmable

luminaires) or switch it off (in the case of non-dimmable luminaires), depending on whether

the nominal temperature is exceeded.

When calculating the reduced light intensity of dimmable luminaires, the current illumination

run as well as possible simulations are included.

Example for Dimmable Lamps

Nominal temperature = 26.0 °C, min. temperature excess = 2.0 °C, max. temperature excess = 4.0 °C, this results in the following table

With the temperature-dependent light reduction, it is possible to prevent your aquarium

from being further heated by the illumination on hot summer days. This feature is especially

useful when an existing cooling system cannot provide sufficient temperature reduction.

The following parameters can be set:

 The determining Temperature sensor (for example, temperature 1 if you have

connected one temperature sensor. If you connected more than one, select the

sensor to be used for the measurement).

 The Temperature excess minimal – If the nominal temperature is exceeded by this

value, then the reduction of the illumination intensity of the affected lamps begins,

adjustable from 1 °C up to 5 °C - this setting is only relevant for dimmable lamps!!

 The Temperature excess maximal – If the nominal temperature is exceeded by this

amount, the lighting concerned is switched off completely, adjustable from 2 °C to 10

°C, must be at least 1 °C higher than the minimum temperature limit - this setting is

only relevant for dimmable luminaires!

 The Shut off limit – If the nominal temperature is exceeded by this amount, non-

dimmable luminaires are switched off. A value between 1 °C and 10 °C is adjustable.

These lights are not switched on again until the programming of the corresponding

illumination run defines again a switch on (luminaire has been switched off according

to the programming, for example at night - and is switched on again, for example in

the morning). A drop in the temperature alone does not lead to a new switch-on,

which is particularly useful with gas discharge lamps, since these should not be

switched on and off continuously. This setting is only relevant for non-dimmable

luminaires!

EN 2017-02-06 28

ProfiLux 4 Programming Guide

Example

You would like to have for the illumination from Monday to Friday other settings than for Saturday and Sunday, so you need 2 different illumination runs. First you set both illumination runs (e.g. illumination run 1 for Monday to Friday and illumination run 5 for Saturday and Sunday) according to your wishes. Afterwards you set e.g. Variable Illumination 1 accordingly (Monday: 1, Tuesday: 1, …, Friday: 1 and Saturday: 5 and Sunday: 5).

Finally you choose the function Variable Illumination 1 as function for the corresponding 1-10 V-interface (see also System ->1-10 V interface) resp. for the corresponding switchable socket (see also System ->Socket outlet function.

3.12 Variable Illumination

This function allows you to use different illumination runs for a luminaire on different

weekdays.

Up to 16 variable lighting programs can be defined. After selecting the program (1 to 16), you

can set for Monday to Sunday, which lighting sequence (1 to 16, Illumination run) should be

used on the respective day.

3.13 Mitras Lightbar

Activate this setting when you have connected our Highpower LED Illumination Mitras®

Lightbar. You can also specify which of the available serial interfaces (usually COM1) are to be

used to control the Mitras Lightbar.

Here you can change the output power of the Mitras Lightbar.

3.14 Light demo

The Lightdemo serves for demonstration purposes. After activation, the LEDs are alternately

dimmed up and down.

With the keyboard the Lightdemo can be varied:

Arrow up and down – Color change faster or slower

Arrows left and right - Change the color pattern

Return - Freeze the current color pattern, press Return again restarts the automatic

sequence

EN 2017-02-06 29

ProfiLux 4 Programming Guide

Esc finishes the light demo.

3.15 Time lapse

The Time lapse can be used for test and demonstration purposes. With this function you can

view the adjusted illumination run in time lapse.

There is a manual time lapse (indicated by an M in the upper right) and an automatic time

lapse (indicated by A). You switch between both modes by pressing Return.

In manual time-lapse, you can set the time to be simulated, at which the appropriate lighting

is to be displayed.

During the automatic time-lapse, the time to be simulated is constantly incremented, you can

set the speed of the time-lapse. Set the duration, in seconds, to be used for 24-hour

simulation.

Esc finishes the time-lapse.

3.16 Acclimation

The acclimation function provides a simple and comfortable way to automatically change the

brightness of the light over a span of several days. We recommend using this simulation for

acclimating corals/plants to a new lighting program or when corals have been newly brought

in.

After activating, the following settings can be made:

Start date – The acclimation period begins on this day

Start percent- With this value, all dimmable lights are multiplied at the beginning of the

acclimation

End date - The acclimation period ends on this day

End percent - With this value, all dimmable lights are multiplied at the beginning of the

acclimation

During acclimatization, a dimming factor is calculated daily. The individual illumination runs

are converted according to this factor.

Example: Start on 01.12.2016 (12-01-2016) with 50%, end on 03.12.2016 (12-03-2016) with

100%

EN 2017-02-06 30

ProfiLux 4 Programming Guide

Note

In order to achieve maximum flexibility, the settings of the maintenance function refer directly to the hardware (switch sockets and 1-10 V interfaces) ...

...and not on control and regulation functions (e.g., temperature control or illumination channels).

Then the lighting channels are operated with 50% of the normally set brightness on the

01.12.2016 (and also before), on the second day with 75%, and on the last day with 100%

(and also thereafter).

Starting and ending percentages can be adjusted as needed; thus an increase as well as a

lowering over a certain period of time is possible..

3.17 Shift Curves

This function allows you to move complete illumination runs.

 Select the illumination(s) whose illumination run(s) you want to move.  Then determine the time offset and confirm with ->RETURN

4 Extras

Special functions and settings are summarized here. The following submenus are provided.

4.1 Maintenance

During the maintenance and care of the aquarium, it can be helpful to set the switch state of

some switch sockets or the brightness of luminaires explicitly.

An example would be switching the heaters off, setting the flow to minimum and setting a

dimmable lightbar to 80%.

ProfiLux 4 offers 4 separately adjustable Maintenance programs.

In the Maintenance menu, you can set the maintenance parameters under Settings. For quick

access, the maintenance programs are positioned on top, one after the other. The menu

item Settings will show up afterwards. Scroll down the menu until you reach Settings. Then

select the Maintenance program you want to edit.

Set affected 1-10V interfaces

EN 2017-02-06 31

ProfiLux 4 Programming Guide

Here you can select the 1-10V interfaces to be affected during maintenance. All non-selected

interfaces continue to operate normally and program-controlled during maintenance.

Adjust affected 1-10V interfaces

For the previously selected 1-10V interfaces, you can set here which voltage in percentage

they shall output during the maintenance.

Select affected socket outlets

Here, you can set which sockets should be influenced during maintenance. All unselected

sockets continue to operate normally and program-controlled during maintenance.

Adjust affected socket outlets

The switch state (on or off) can be set for the previously selected sockets during

maintenance.

The following two settings are available only if a Mitras Lightbar is connected.

Select affected Mitras Lightbar LEDs

Here it is possible to adjust which LEDs of Mitras Lightbar are to be influenced during

maintenance. All non-selected LEDs continue to operate normally and as programmed

during maintenance.

Adjust affected Mitras Lightbar LEDs

For the previously selected LEDs, the brightness can be adjusted as a percentage during

maintenance.

Maximum length maintenance

This time (up to 240 minutes) determines the length of time the maintenance is

automatically switched off.

The automatic shutdown after a certain period of time prevents maintenance from

remaining permanently active if you forget to switch it off again. If maintenance is allowed

for an indefinite period, enter 0 here.

Activate the Maintenance program in the Maintenance menu with Start.

While the maintenance program is active, the selected sockets have the set switching states

and the selected 1-10 V interfaces output the set voltages.

ProfiLux 4 signals an active maintenance program with a blinking hammer symbol in the

display.

End the Maintenance program from the Maintenance menu by selecting Stop.

EN 2017-02-06 32

ProfiLux 4 Programming Guide

Note

During maintenance, the alarm monitoring of all sensors is switched off!

Note

To avoid damage to the microbiological climate of your filter, do not select this time longer than absolutely necessary (approx. 5 to 10 minutes)!

4.2 Feeding Pause

ProfiLux 4 offers 4 independent feed pauses, which can be started and set in the feed pause

menu.

Scroll down in the Feed Pause menu until you get to Settings.

Select the feed pause (1 to 4) whose settings you want to adjust.

Set the duration of the feed pause (length feeding pause). This determines how long the

activated feed pause takes, which has been started manually with the Esc key or

automatically by a timer. It can be set between 0 and 120 minutes (0 means that this feed

pause is not used).

Furthermore you can set which effect the feeding pause shall have:

Stop filter? – with the selection of Yes the switchable socket with the function Filter (1 to 4,

depending on the feeding pause you are editing here) will be switched off during the feeding

pause.

Finally, you have to set whether a timer can activate the feed pause, if Yes is selected, choose

which timer should start this feeding pause.

If a timer should activate this feeding pause then the feeding pause is activated as long as

this timer is active. The feeding pause remains furthermore active for the time set under

Length feeding pause. This makes sense, if this timer controls an automatic feeder or a dosing

pump.

The behavior of the current pumps during the feeding pause can be defined in the settings

of the current pumps (Extras->Current->Pump settings).

EN 2017-02-06 33

ProfiLux 4 Programming Guide

You start a feed pause by pressing the Esc key. If more than one feed pause is used, then the

appropriate feed pause has to be selected. The food pause can be interrupted by pressing

Esc again.

4.3 Internal Time

This function is used to display the internal clock (see also ->Clock). This function is only for

diagnostic purposes, settings cannot be made here.

4.4 Info & Support

After selecting this menu item, information about the software version, model and our

homepage is displayed one after the other (automatically after the lapse of a certain time or

by pushing a key).

4.5 Current

ProfiLux can control (current) pumps in a variety of ways; subsequent pumps are suitable for

control:

• Pumps with an analog control signal input (mostly 1-10V-interface), such as those

from Tunze®, Royal Exclusiv® or Abyzz®, are connected to a 1-10V interface port of

the ProfiLux (for the connection to ProfiLux you need the corresponding accessory)

• Pumps whose speed is adjustable via phase controlled modulation (therefore our

dimmable powerbar Powerbar2Dim is necessary)

• EcoTech®-pumps of VorTech® (with our module VorTech-Controller)

• Electronical external filter Professionel 3e® from Eheim® (with our module Eheim-

Controller)

• Some low-voltage pumps, e.g. Koralia® from Hydor® (with our module PumpControl1)

Furthermore, non-controllable pumps can be switched via switchable sockets, see also

System-> Socket outlet function. These can then of course only be switched on or off but not

regulated.

The current control is organized in groups, one group consists of one or several pumps. The

settings can be made separately for each group and for each pump. The group settings

define the pumps belonging to the group, the operational mode and the time settings

(depending on the operational mode).

For each pump, settings such as wave duration, minimal or maximal speed or the behavior

during the feed pause can be set individually.

EN 2017-02-06 34

ProfiLux 4 Programming Guide

Note

"Pump active" means that the pump is running continuously between min. and max. current speed and thus generates waves. A socket assigned to the flow pump is then switched on.

"Pump inactive" does not necessarily mean that the pump is off, but that it runs at its minimum power. A socket assigned to the flow pump is then switched off.

The group settings determine when and for how long which pump is active in this group, the pump settings determine the behavior of the pump during activity and inactivity.

4 independent groups can be programmed. A group consists of up to 4 (or up to 16) pumps

which can be independently controlled.

4.5.1 Nocturnal Change

For the current simulation, a Nocturnal change of the pump power can be adjusted. If the

Nocturnal change is activated, the start and end times must also be entered. Within these

times, the pumps are operated with the power set for the night. The night change affects all

pumps in all groups.

4.5.2 Group Settings

The following parameters can be set for each group:

4.5.2.1 Operational Mode

Here you can set the operating mode for a group. The individual groups may have different

operating modes.

Off – The pumps of this group are permanently off.

Permanent – The pumps are permanently active and run synchronously.

Permanent alternating – The pumps are permanently active and operate alternating, i.e. if

pump 1 runs at maximum speed, pump 2 runs at minimum speed and vice versa.

Sequence 1 – Here, always exactly one current pump of this group is switched on alternating.

The duration for the change from one pump to the next one can be set, see below. When the

last pump of this group was active, the cycle starts again with the first pump of this group. If

this group consists of 2 pumps, then the ebb-tide-simulation is generated. If only one pump

WARNING

If a switching socket is to control the corresponding flow pump, the time period must not be too small - otherwise too frequent switching can lead to damage to the socket or the pump!

etc.

Random – Using a random generator, all, some or none of the pumps belonging to this group

are activated in a continuous random variation. The time until the switching state changes

again can be set (see beneath).

4.5.2.2 Assign Pumps

Here you can define which pumps belong to this group. A pump must not be assigned to

several groups.

4.5.2.3 Tide Duration

In the modes Sequence, Surge or Random you can set the time after which the switch on state

of the pumps shall change again. Enter a Minimal and a Maximal tide duration.

The time after a new switch-on state is to be assumed is determined by random-number

generator in the range of these two times.

Shall the time be always the same, the same value must be entered for Minimal and Maximal

tide duration.

The Minimal and a Maximal tide duration is adjustable between 1 second and 8 hours.

4.5.2.4 Wave

The type of wave generation can be set individually for each group:

Note

Waves have no effect on non-controllable pumps, which are connected via switchable sockets.

 Sinus waves – Gentle acceleration and slowing down of the pump  Right-angled waves – abrupt changes

Then set the Minimal and Maximal wave duration in a range of 0.4 and 60 seconds.

The random number generator determines a duration within these limits for each wave.

If all waves should have the same duration, enter the same values for Minimal and Maximal

wave duration.

The technical possibilities of the pump must, of course, also be taken into consideration for

the wave duration.

Finally, the random wave reduction can be set from 0% to 100%.

The bigger the value, the more different the single wave crests become.

 At 0%, each wave peak reaches the maximum (wave crests are always equal),  At 100%, the wave waves fluctuate randomly between minimum and maximum.

In the following, the flow pattern can be seen on a controllable pump (settings: Minimal =

30%, Maximal = 90%, Wave duration = 10 s, Wave form = Sinus):

EN 2017-02-06 38

ProfiLux 4 Programming Guide

4.5.3 Pump Settings

The following settings can be made individually for each pump:

 Minimal - minimal power (during a wave trough or if pump inactive)  Maximal – maximal power (during a wave crest)  Night – maximal performance during nocturnal change  Storms – maximal performance during a storm  Behavior while feeding pause – adjustable is

 uninvolved (Feeding pause does not affect this pump),  at minimum (pump is operated only with minimum

power during the feeding pause)

 or off (pump is switched off during the feeding pause).

4.6 Eheim

With the accessory ProfiLux EHEIM controller, it is possible to connect an Eheim type

Professional 3e external filter to ProfiLux 4.

ProfiLux 4 is then able to control the flow rate of the external filter as a function of a flow

pump channel.

The external filter then follows within the scope of the technical feasibility - the flow rate of

an external filter cannot, of course, be changed as quickly as that of a current pump – to the

active current of the selected pump channel.

Here all functions of the current pump control of the ProfiLux, like e.g. Nocturnal Decrease or

Feeding Pause, are available.

Proceeding:

First set up a pump group and current pump according to your requirements.

After that you can make the following settings in the Eheim menu:

 EHEIM-Controller connected – Selection of Yes required for ProfiLux 4 to control the

ProfiLux EHEIM controller

 Current pump – Select the channel of the flow pump which is to control the flow rate

of the EHEIM external filter

EN 2017-02-06 39

ProfiLux 4 Programming Guide

WARNING

Select EHEIM controller connected only if you have actually connected a ProfiLux EHEIM controller, otherwise the PC communication with RS232 will be disturbed!

Note

You can display the actual flow and the days up to the next filter cleaning on the ProfiLux display, see menu item Extras-> Display.

4.7 Display

Here, you can set which current values should be displayed on the display during normal

operation.

If several elements are selected, they are displayed alternately. These settings also affect the

display on a possibly connected ProfiLux Touch.

The following setting options are available in this menu:

 Display duration– Time the display remains constant until the next value is displayed  Select illumination– Here you can select which lighting channels are to be displayed  Select controller (only if measurement inputs are available) – Select the controllers

whose values and states are to be displayed (e.g. pH and temperature)

 Select miscellaneous – Selection of other elements that can be displayed (e.g., moon

phase, level, flow sensor, or EHEIM)

 Time & Date – It can be set whether the current time and the date are displayed never

always or rotating.

4.8 Measurement Data

ProfiLux 4 can record measurement data.

 Storage size – Max- 8192  Memory type – FRAM (nonvolatile memory), in case of a voltage supply failure the

measured values keep stored

If the measurement value storage is full, then the oldest data is overwritten.

EN 2017-02-06 40

ProfiLux 4 Programming Guide

Example calculation max. measurement recording duration

Size of the measurement data storage 500 storage elements, measurement data of 2 sensors shall be stored, recording every hour

-> Recording period = 1 h * 500 / 2 = 250 h = 10.4 days

Example setting of max. storage size

You want to store the measured data of 3 sensors (for example, temperature, pH and redox) half-hourly, but the values in the memory

For a detailed analysis and further processing of the measurement data, a PC with our

program GHL Control Center is necessary. It can read out measurement data and store it as

text file. A simplified measurement data analysis can also be made directly at the device, see

menu item Analysis beneath.

Per sensor and measurement time point, one storage space in the measurement data

storage is allocated.

Under the menu item Measurement data the following sub-menus are available:

 Settings – First, set the max. storage size which is reserved for the measurement data

recording. The reduction of the max. Memory size is only useful, if you want to restrict

the time period for data collection. See also the example shown below.

After that set the measuring period between 1 minute and 12 hours (after this time

the current values are stored). Finally, it is possible to select which of the available

sensors are to be taken into account when measuring the measured values.

A change in the settings may lead to the deletion of existing measurement data.

Before you save the new settings, you are first asked if you want to “Clear data?”

 Erase measurements – All currently stored measurement values are deleted.  Status – Shows first when the last measured values were recorded, afterwards the

memory status and how many of the measured data have not yet been collected from

the PC.

 Analysis - After the sensor whose measurement data is to be evaluated has been

selected, the upper line displays the average value and the lower line the minimum

and maximum values. The three values are determined based on all the data

currently stored in the memory.

EN 2017-02-06 41

should be a maximum of two days old, so that the minimum, maximum and average values refer always to the last two days.

-> Max. storage size = 24h / 0.5h * 3 = 144

Tip

If ProfiLux 4 is set to German, this menu appears under Extras-> Sprache. Select this option to change the language.

ATTENTION

The sensors for pH, conductivity, redox and oxygen must be calibrated before the first use and thereafter regularly (all 2 – 4 weeks)!

Check in any case if all sensors show plausible values!!

4.9 Language

The language in which ProfiLux 4 displays texts can be set here.

5 Sensor Settings

With the exception of the level sensors, you can make all sensor-related settings under this

menu item. The settings for level sensors can be found in the following menu item Level of

the ProfiLux 4 menu.

ProfiLux 4 automatically shows you all the sensors already installed at the factory.

These are:

 Temperature 1  pH-value 1  Redox 1  Conductivity 1

If you have connected several sensors of the same type, then the numbering by the ProfiLux

4 is accomplished as follows: The permanently installed connections in the ProfiLux 4 have

the smallest number, the numbering of additional connections on ProfiLux Expansion Cards

increases with the slot number in which the cards are plugged.

Down-regulation: When the nominal value is undershot, the downregulation is switched off, the down-regulation is switched on again when the nominal value is exceeded by more than half the hysteresis (see also Sensor settings-> Hysteresis).

Up-regulation: If the actual measured value exceeds the nominal value, the up-regulation is switched off, the up-regulation is switched on again if the nominal value is undershot by more than half hysteresis.

First select the sensor whose settings you want to change and confirm with RETURN.

For the sensor settings of each individual sensor, you can select the following options:

5.1 Activity

Please make sure that the selected sensor and the associated measurement recording and

control are active (standard: Yes).

If this is set to No, the control and sensor monitoring for this sensor will turn off and all

switch sockets connected to this sensor will be deactivated.

If this input is not to be used, please deactivate it. Otherwise, ProfiLux 4 may assume a sensor

defect and display an alarm.

A deactivated sensor is displayed with --- in the display.

5.2 Nominal Value

The nominal value (the value to be controlled) can be set here. The nominal value and the

current value (actual value) determine whether it is regulated upwards or downwards.

WARNING

For safety reasons, a possibly set nocturnal change (own menu item nocturnal change) is deactivated during the processing of the nominal value!

If you need to make a nocturnal change, you must reactivate it after the nominal value processing.

Note

Please note the following in the temperature control:

The heat radiation of the lighting and the outside temperature can affect the water temperature. If there is no cooling, it is possible that the set-point temperature is exceeded.

Depending on the difference between the desired and the current temperature, the heaters or the cooling are switched. The following states can occur:

Tubular heater and substrate heating on / Only substrate heating on / All off / Cooling only

ProfiLux 4 is programmed in such a way that the substrate heating takes precedence over the tubular heater. This makes an optimal heating of the substrate possible. The tubular heater is then switched on when the substrate heater alone is no longer sufficient.

EN 2017-02-06 44

ProfiLux 4 Programming Guide

Example using a pH sensor

Nominal value = 7.0 and Hysteresis = 0.4

The down-regulation-socket switches on at 7.2 and off again at 7.0, the up- regulation-socket switches on at 6.8 and off again at 7.0.

It can be seen that the control oscillates by 7.1 or 6.9 and not exactly by the adjusted nominal value (7.0). This is necessary to allow simultaneous use of up- and down-regulation.

5.3 Operation Hours

In order to always know how long the sensor is already in operation, ProfiLux 4 provides an

associated operation hour counter for sensors.

The operation hours are written cyclically every 1 h into the non-volatile memory. This

ensures that operating hours are maintained even in the event of a power failure.

After selecting the menu item Operation hours, the operation hours of the sensor are

displayed. After a few seconds or by pressing a key, you will be asked “Reset?” A confirmation

with Yes resets the operating hours counter to 0 h.

5.4 Hysteresis

The so-called hysteresis comprises the distance from switching-on the socket outlet down

regulation to switching-on the socket up-regulation of the respective sensor.

The hysteresis that can be adjusted here determines the distance between these switching

points and is necessary in order to reduce the switching frequency.

In the case of temperature sensors, the hysteresis that can be adjusted here comprises the

distance from switching on substrate heating to switch-off (main) heating.

The switching on of the cooling lies out of the hysteresis, so that a simultaneous operation of

substrate heating, heating and cooling is possible (see also note for temperature sensors

below).

The factory hysteresis setting does not normally need to be changed. A reduction in the

hysteresis is useful if the control accuracy is to be increased. This also increases the

switching frequency.

Note for temperature sensors

The adjusted hysteresis also depends on when the cooling is active. The switching-on point of the cooling also depends on the cooling difference (see also Sensors-> Cooling difference) and can be calculated as follows:

T = nominal temperature + 5/6 * hysteresis + cooling difference

With a hysteresis of 0.2 °C, this results: T = Nominal temperature + 0.167 °C + cooling difference.

5.5 Alarm

ProfiLux 4 can monitor the currently measured value of a sensor and react in various ways in

the event of an excessive deviation.

Please first set whether the alarm should be active. If you selected Yes, please proceed as

follows:

 Determine the Maximum deviation of the actual value from the nominal value.  Select whether you want to disable this control in the event of an alarm (Shut-off

control?).

Resolution

Note

If you are setting a Virtual sensor of the type Average, then you can additionally set a Comparative alarm.

DANGER

 Set the alarm settings with utmost caution and care.  Be absolutely sure that the alarm limits are not exceeded in normal

operation.

 The manufacturer declines any responsibility or liability for damage!

 Select whether the alarm should be inactive during water changes (Disabled at AWC?)

If you have chosen inactive during water changes, the alarm monitoring is temporarily

switched off during an automatic water change (AWC).

After activation of the alarm, the corresponding actual value is constantly compared with the

nominal value by ProfiLux 4. If the deviation (overshoot or undershoot) is greater than set

under Maximum deviation, an alarm is triggered. The hysteresis and a possible nocturnal

change are automatically taken into account during the nominal / actual value comparison;

in the case of temperature sensors, the Cooling difference is also taken into account.

In the case of a Virtual sensor of the type average, the measured values of the two sensors

from which the average value is formed are compared. If the difference of the measured

values is larger than the Comparative alarm, an alarm is also triggered.

During an alarm, the red alarm LED will light up and the buzzer will be activated depending

on the mode selected (see also under System ->Alarm). In addition, a switch socket can be

programmed so that it is switched on in case of an alarm.

If the controller shut-off has been set for the alarm, all sockets which are involved in the

control of this sensor are deactivated immediately in the event of an alarm!

The alarm settings should be set with the utmost care. It is imperative that alarm limits are

not exceeded during normal operation!

Example for the calculation of the lower and upper temperature alarm limit

 Nominal value 26.0 °C  Nocturnal change by -2 °C active  Overall hysteresis 0.2 °C  Maximum devitation 1.5 °C  Cooling difference 2.0 °C

Thus resulting :

Lower limit = 26.0 °C – 2.0 °C – ½ * 0.2 °C – 1.5 °C = 22.4 °C

Upper limit = 26.0 °C + 5/6 * 0.2 °C + 1.5 °C + 2.0 °C = 27.7 °C (5/6 because of the upper switching point of the cooling, see also Sensor settings ->Hysteresis)

5.6 Nocturnal Change

With this setting, you can determine whether the value to be controlled is to be changed at

night.

By default, the night change is disabled. If you have activated the nocturnal change with Yes,

you can set how much the value is to be changed at night and set the start and end times.

5.7 Summer Switching

(Only for temperature sensor)

With this feature you can activate the summer switching and adjust it to your needs. As

mentioned before, it is possible that the water temperature exceeds the nominal

temperature. In this case the substrate heater would remain switched off and there would

be no circulation in the substrate.

By activating the summer switching feature, the floor heating is operated in such a way that

the water temperature is not significantly increased. The summer circuit is switched off by

default.

After you have activated the summer switching with Yes, you can adjust the Intensity of the

summer switching (5-30).

This number corresponds to the operating time of the substrate heater in minutes at a

temperature exceeding of 1 °C. The operating time is calculated by the controller depending

on the temperature exceeded.

EN 2017-02-06 49

ProfiLux 4 Programming Guide

ATTENTION

If you have set an upper temperature limit on the heating element for safety reasons, you must change it if the temperature rises.

Note

Depending on the application area of the ProfiLux 4, it may be useful to set the measuring range before calibration of the sensors.

If the temperature is below the set temperature, the operating time is increased. If the

temperature is exceeded by more than 3 °C, the substrate heater will be turned off in any

case.

The settings for the nocturnal change are taken into account.

This intelligent and elaborate process has the advantage that you always achieve the best

possible substrate circulation on your aquarium!

5.8 Therapy

(Only for temperature sensor)

If a fish disease occurs, it may be useful to change the water temperature for some time.

When the Therapy function is activated, the temperature is changed by the desired value

(reduction by 5 °C to increase by 5 °C) for the set time (3 - 21 days).

The temperature change at the beginning and end of the therapy is done gently (within one

day).

5.9 Calibration

This function is used to calibrate a sensor and the associated electronics. Please allow some

time for this. The calibration with ProfiLux 4 is simple and is menu driven. Please follow the

instructions in the display carefully.

Not all sensors can or must be calibrated (see table Calibration values below).

For all sensors that can be calibrated, the following principle applies:

Only if ProfiLux 4 has been calibrated with the connected sensor, correct values can be

determined.

EN 2017-02-06 50

ProfiLux 4 Programming Guide

Please refer to the following menu item Measurement range.

DANGER

 Please observe the information on the display.  When prompted (RETURN arrow appears in the display), press the

RETURN key after each step

 During calibration, wait for the signal sound before proceeding!  Take the time to calibrate  Check the calibration as explained below ->Control of sensor

calibration

Do not use the sensor until the correct function and calibration are free of doubt!

The calibration procedure is different for each sensor type.

The differences between the individual sensors are discussed in the following chapters.

5.9.1 General

Calibration is always necessary with new sensors. Also, the calibration should be repeated

from time to time (every 2-4 weeks) because of the aging process of the sensor. Please

observe the instructions of the sensor manufacturer. Before immersing the sensor in a

calibration solution, the sensor must be carefully dried with a dry, lint-free paper towel.

For all subsequent calibrations:

5.9.2 Calibration Tolerance

At the beginning of a calibration, you are requested to enter the Calibration tolerance for the

respective sensor (between 1 and 3), which is to be taken as the basis for the calibration.

In principle, calibration procedures should be carried out with the smallest possible

calibration tolerance, which is usually 1.

With old sensors, the measured value may not be sufficiently stabilized and calibration is not

possible. In some cases, it is possible to calibrate this sensor by increasing the calibration

tolerance, but this has a negative effect on the measuring accuracy.

In some sensors, you have the option of changing the values to be calibrated.

5.9.3 Overview of the Calibration values

(If the minimum and maximum are the same, then the calibration value cannot be changed)

5.9.4 Temperature Sensor (Analog)

This applies exclusively to external analog temperature sensor inputs (for example, from PLM

Temp)

The already installed sensor input for the digital temperature sensor of the ProfiLux 4

can and must not be calibrated.

Additional external analog temperature sensor inputs (for example, of additional expansion

cards PLM-Temp) must be calibrated!

Each ProfiLux Expansion Card with temperature sensor input is accompanied by a calibration

document.

Please enter the two values listed under Calibration ADC1 and Calibration ADC2 during

calibration. After entering these two values, the temperature sensor input is calibrated.

5.9.5 pH Sensor

 Connect the pH sensor  Set the calibration tolerance  Determine the Calibration value 1 and then the Calibration value 2 and confirm with

RETURN

 To calibrate the Calibration value 1: Immerse the sensor in the calibration liquid

suitable for your specified calibration value and press RETURN

 Leave the sensor in the calibration liquid until the signal tone  The sensor is now calibrated to Calibration value 1  Dry the sensor and continue with the calibration of the Calibration value 2  If no errors have occurred, save the calibrated values by selecting Yes and confirm

with RETURN

 Check the calibration as described below

The pH sensor is now ready for use. Based on your calibration, ProfiLux 4 can now determine

the pH value.

5.9.6 Redox-Sensor

For the redox sensor calibration, you need a so-called Null-plug, which is supplied with

ProfiLux 4 as well as our redox expansion cards (PLM Redox). The plug must be plugged onto

the sensor connection of the ProfiLux 4 (corresponding white BNC socket on the back of the

housing).

 Set the calibration tolerance  Determine the Calibration value 2 and confirm with RETURN  Plug the Null- plug ->RETURN  Wait for the signal sound  Disconnect the Null- plug and then connect the Redox sensor ->RETURN  Immerse the sensor in the Calibration liquid to suit your specified Calibration value -

>RETURN

 Wait for the signal sound  If no errors have occurred, save the calibrated values by selecting Yes and confirm

the Redox value.

EN 2017-02-06 53

ProfiLux 4 Programming Guide

Tip

The most accurate values for the conductivity value determination are obtained by means of a continuously measured value.

Tip

The easiest and fastest way is to equalize the fluid temp is to place the closed container of the calibration liquid in the aquarium until the temperature has adjusted. This is only useful if the aquarium temperature is known.

5.9.7 Conductivity

The conductivity of a liquid is strongly temperature-dependent. For the exact determination

of the conductivity by ProfiLux 4, this results in a so-called Temperature compensation for each

measurement.

During calibration, you will be asked how ProfiLux 4 is to perform the temperature

compensation. ProfiLux 4 offers you two options:

 Aquarium temperature manual: The temperature compensation is carried out by

means of a fixed set temperature (Aquarium temperature manual). Then enter the

temperature.

 Aquarium temperature by using a continuously measured value: Select the desired

Temperature sensor for temperature determination.

You will be prompted to enter the temperature of the calibration liquid (Calibration liquid

temperature).

The actual calibration is then started.

Please note the information on the display. After each step, press the RETURN button and

wait for the signal tone before you continue.

 Connect the Conductivity sensor.  Set the Calibration tolerance ->RETURN  Determine the Calibration value 2 and confirm with RETURN

 Wait for the signal sound  If no errors have occurred, save the calibrated values by selecting Yes and confirm

with RETURN

 Check the calibration as described below

The Conductivity sensor is now ready for use. Based on your calibration, ProfiLux 4 can

determine the Conductivity.

5.9.8 Oxygen Sensor

In contrast to all other sensors, the oxygen sensor is calibrated in 2 steps. The first

calibration is the so-called Null-calibration. The second calibration is the so-called Air

calibration.

There must be a time interval of at least 30 minutes between both calibrations, as

otherwise sensible values cannot be determined.

This means that the calibration process must be started two times:

During the calibration, you will be asked for how ProfiLux 4 is to perform the Temperature

compensation and the Salinity compensation. ProfiLux 4 offers you two options:

 Aquarium temperature manual: The temperature compensation is carried out by

means of a fixed set temperature (Aquarium temperature manual). Then enter the

temperature.

 Aquarium temperature by using a continuously measured value: Select the desired

temperature sensor for temperature determination.

 Salinity manual: The salinity compensation is carried out by means of a fixed set

salinity (Salinity manual). Then enter the salinity. For freshwater, please enter 0.0

 Salinity by using a continuously measured value: Select the desired Conductivity sensor

(only sea water possible) for the determination of the measured value

The temperature of the air at the calibration site (above the water surface) is also required.

Then the calibration starts.

EN 2017-02-06 55

ProfiLux 4 Programming Guide

Note

During the calibration measurement, 2 numbers can be seen in the lower line. The left number indicates the maximum remaining time in seconds.

If the measured value has not stabilized sufficiently after this time has elapsed, a faulty sensor is emitted and the calibration is interrupted.

The right number shows the measured value in an internal representation. ProfiLux 4 detects automatically if this value has stabilized and then terminates the measuring process.

First step: NULL CALIBRATION

 Disconnect the sensor from the BNC connector ->RETURN  The NULL CALIBRATION is started  If no errors have occurred, save the calibrated values by selecting Yes and confirm

with RETURN

 Reconnect the oxygen sensor to the running ProfiLux 4.  Wait at least 30 minutes to continue with step two

Second step: AIR CALIBRATION

The Air calibration is only possible if a Null calibration has been performed successfully at

least once. Before the Air calibration, the sensor must be connected to the ProfiLux 4 for at

least 30 minutes!

 Select Air calibration ->RETURN  Select the Temperature compensation and proceed accordingly  Select the Salinity compensation and proceed accordingly  Enter the temperature of the air at the calibration location ->RETURN  Keep the sensor about 1 cm (0.39”) above the water and do not touch the surface of

the water with the sensor

 Start the measurement with ->RETURN  If no errors have occurred, save the calibrated values by selecting Yes and confirm

with RETURN

 Check the calibration as described below

The Oxygen sensor is now ready for use. Based on your calibration, ProfiLux 4 can now

determine the dissolved oxygen.

Use the sensor for controlling tasks only when the correct function and calibration

have been proved without any doubts!

5.10 Display

For certain sensors, you can set how the measured value is to be displayed:

Overview of display options:

EN 2017-02-06 57

ProfiLux 4 Programming Guide

ATTENTION

Please note that you can only make settings in the default setting (for example, °C)!

5.11 Cooling Difference

(Only with temperature sensor)

If the cooling is not to be active within the usual control (observing the nominal temperature

with regard to the hysteresis), but only delayed, the Cooling difference can be used to

determine how far the temperature must exceed the set temperature until the cooling

becomes active.

Values can be set between 0.0 °C (no delay, cooling is active immediately when the nominal

temperature is exceeded) and 5.0 °C (maximum delay, cooling is active when the nominal

temperature is exceeded by 5.0 °C). The cooling difference also affects the alarm monitoring.

5.12 Extension

(Only with temperature sensor)

If the cable to the temperature sensor is extended (or shortened by removing an extension),

ProfiLux 4 must compensate for the measuring errors resulting from the changed cable

length. Changing the cable without compensation can result in a significant measurement

deviation.

For ProfiLux 4 to calculate the compensation correctly, proceed as follows:

The sensor must be connected and in the water during the entire process. The water must

not be subject to major temperature fluctuations in the next few minutes.

 Select this menu (Temperature-> Extension).  Wait for the wait.  Change the extension cable (insert or remove), confirm with RETURN.  ProfiLux now calculates the compensation values  Then you can save these values  If no errors have occurred, save the calibrated values by selecting Yes and confirm

with RETURN

 Check the calibration as described below

EN 2017-02-06 58

ProfiLux 4 Programming Guide

Based on your execution, ProfiLux 4 displays now the correct (compensated) temperature

value.

5.13 Measurement Range

For some measuring inputs for sensors, it may be necessary to first set the Measuring range

before calibration.

 Select the respective sensor under Sensor settings and confirm with RETURN.  ProfiLux 4 offers you the possible measuring ranges for selection

Temperature

Here the measuring range can be selected for the connected temperature sensor. There are

2 types of water temperature sensors:

Aquarium – Measuring range approx. 11.5 °C (52.7°F) to 38 °C (100,4°F)

Pond - Measuring range approx. 0 °C (32°F) to 40 °C (104°F)

At default, the measuring range is set for the aquarium. Change the measuring range when

you connect a pond sensor! If the measuring range and sensor used do not match, incorrect

temperatures are measured!

Conductivity

If the relevant input is an onboard input of ProfiLux 4, the measuring range can be changed

here - for seawater or freshwater. Please note that when the measuring range is changed, all

settings for this input are lost and set to the factory setting.

5.14 Density Offset

(Only with conductivity sensor saltwater)

For the density display of seawater, an offset between -0.005 and +0.005 can be set here if

the displayed density value deviates from the actual value.

5.15 1-10 V max. at…

(Only with temperature sensor)

This setting allows you to define at which temperature the assigned 1-10 V interface (for

example, for PTC or PropellerBreeze) should have the maximum output voltage.

The connected device then has the maximum power with this temperature deviation.

Adjustable are values between 0.2 °C und 10 °C.

EN 2017-02-06 59

ProfiLux 4 Programming Guide

5.16 Current Actual value

The current actual value is displayed here. Press any key to stop the display.

5.17 Operation Mode controller

Here you can set how the control should work.

For most cases, the default Two-position controller is perfectly adequate and does not need to

be changed. For some special conditions, the other operating modes are suitable for

optimizing the control behavior. The following operating modes are available:

 Two-position controller

This is the most common mode. At two switching points, which are determined by

nominal value and hysteresis, an associated socket is switched on or off. See also

Sensor Settings-> Hysteresis.

 Pulse/Pause fixed

If the actual value deviates from the nominal value by a half hysteresis, the

corresponding switch socket is switched on for an adjustable time (Pulse duration).

After the pulse has elapsed, the socket is switched off again and remains switched off

for at least the set Pause duration. After the Pause duration has elapsed, the socket can

be switched on again by the controller if the actual value deviates from the nominal

value (or still) by half a hysteresis. The switching cycle (Pulse and Pause) starts again.

 Pulse variable

Operates in principle like Pulse/Pause fixed. The difference is, that the actual switch-on

time is calculated depending on the difference between nominal value and actual

value.

The bigger the deviation, the longer the turn-on time will be, but at maximum as long

as the set Pulse duration.

 Pause variable

Operates in principle like Pulse/Pause fixed. The difference is, that the actual switch-off

time is calculated depending on the difference between nominal value and actual

value.

The bigger the deviation, the shorter the turn-off time will be, but at maximum as long

as the set Pause duration.

For these operation modes you need to set additionally:

 Pulse duration

For this duration the corresponding socket is switched on (at the maximum). You can

set a pulse duration between 1 s and 1 h.

EN 2017-02-06 60

Independent level controls

Max. amount of level sensors

Permanently installed level sensor inputs in the device

Standard: 2 + 2

Examples

 pH-control: Pass acid into a pond to lower the pH-value  Temperature-control: Heating of the technical basin (temperature in

the main basin is delayed )

 Conductivity-control: Passing of osmotic-water

 Pause duration

This is the (maximum) time until the control can switch on the corresponding socket

again. It is adjustable between 1 s and 1 h.

The operating modes Pulse/Pause fixed, Pulse variable and Pause variable are useful when the

measured value responds slowly or time-delayed to the control action or substances are to

be supplied only in small doses.

5.18 Signal Filter

Here you can adjust how much the measurement signals are to be filtered.

Permissible values range from 1 (maximum filtering) to 10 (minimum filtering), standard is 5

(average filtering).

The stronger the filtering is, the slower the display of the value will be. If the display of the

measured value fluctuates greatly (e.g., because there is an electromagnetic disturbance or

because the measured value actually changes rapidly), a stronger filtering is useful.

6 Level

ProfiLux 4 can regulate the water level (= level) in various ways.

ProfiLux has 4 inputs for level and leakage detectors and can optionally control 12 inputs. In

addition to level sensors, you need additional accessories (for example, Expansion cards with

level inputs or an Expansion Box 2) for full use of the 12 independent level controls.

EN 2017-02-06 61

ProfiLux 4 Programming Guide

Note

After setting the level control (function), please assign the sockets (hardware) to be switched by the level control, see also under System-> Socket outlet function.

Note

Please note that you can assign any level sensor inputs to any control, this

Level sensors for the determination of the water level can be connected to the level

connections (mini DIN sockets: Level 1 & 2 purple, 3 & 4 green). Since these are double-

allocated sockets, you can connect two level sensors per socket using a splitter cable (Y-cable

PL-LY; not included).

Expansion cards can be used to increase the number of level inputs in ProfiLux 4 or Expansion

Box 2.

The numbering of the sensor inputs is continuous and begins with the sensors permanently

installed in the ProfiLux, followed by the sensor inputs of expansion cards (if available). The

fixed inputs of the first expansion box are then counted, then the sensor inputs of expansion

cards in the first Expansion box. The numbering of sensor inputs of further expansion boxes

is continued according to the same system.

Since the level control is a sensitive matter, various safety precautions have been taken. Our

sensors and the evaluation electronics are designed in such a way that a withdrawal of the

sensor plug or a cable break is interpreted as reaching the desired level and the

corresponding socket is switched off.

In addition to the more cost-effective mechanical float operated sensors, we also offer

optical or contact-less sensors (without mechanical parts). These cannot get stuck in a

position due to contamination. Furthermore, time limits are adjustable which limit the

switching duration of the sockets. Thereby, overflow due to a defect can be prevented in

most cases.

You can adjust the following level controls:

 Control  Input  Diagnostic

After you have selected a level control, you can edit its settings.

EN 2017-02-06 62

ProfiLux 4 Programming Guide

assignment is described below.

6.1 Control

Select which control you want to edit.

There are different operating modes, which are operated with 1 or 2 sensors.

6.1.1 Operation Mode

6.1.1.1 Operation Modes with 1 Sensor:

 Not enabled – This control is not used.  Auto top off (ATO) -

As soon as the sensor registers a low water level, the switch box with the function Fill

water is switched on. When the nominal level is reached, it is switched off again.

Then you can set if the auto top off shall be always active: ATO always? If not, then you

can afterwards select a timer. In this case the selected timer defines when the ATO

may be active for this sensor.

 Leakage detection

If the sensor is activated, ProfiLux 4 assumes a leakage and triggers an alarm. As long

as there is no alarm, the switchable socket with function Fill water is switched on, in

case of an alarm switched off.

 Return pump

As soon as the sensor registers a high level, the switchable socket with the function

Water fill is switched on. When the level falls below, it is switched off again.

6.1.1.2 Operation Modes with 2 Sensors:

 Water change

For adjustable times the water is drained off (switchable socket with function Water

drain is then switched on) until sensor 2 signals the minimum water level. After this,

Water drain is switched off and the socket Fill water is switched on until the water

reaches sensor 1.

-> Sensor 1 signals, that the tank is full again, sensor 2 indicates when enough water

has drained off. Switchable socket Fill water switches fresh water supply, Drain water

switches the outflow.

After selection of this operational mode, the timer has to be selected which shall

EN 2017-02-06 63

ProfiLux 4 Programming Guide

Note

For a switchable socket which is assigned to a control with the function Leakage detection there is no monitoring of the maximum switching time.

For an automatic water change this Maximum on-time is valid for both sockets (drain and fill).

A restart of the ProfiLux 4 (also after a power-cut) resets the error and the time monitoring will be restarted.

define the time of the water change. Please don’t forget to program the selected timer

accordingly afterwards (set here switching period to Event start, see also Clock

->Timers). The water change is then started at the times set there.

 Water change and ATO

Like Water change, additionally socket Fill water and level sensor 1 serve as ATO if

there is no water change running at that time.

 Min/Max-control

Two sensors work together to control a water level. Sensor 1 works as a maximum-

switch, sensor 2 as aminimum-switch. As soon as sensor 2 registers a too low level,

the switchable socket with function Fill water is switched on. When the water level

reaches then sensor 1, the switchable socket is switched off again.

 ATO 2 sensors

Like ATO, but 2 sensors are used to register the same level. Only if both sensors

is activated. So this function offers an additional safety.

6.1.2 Maximum on-time

Due to safety reasons you can set how long the switchable sockets with the functions Fill

water and Drain water may be active at maximum. 8 hours can be set at maximum. Through

this, you can avoid that a defective sensor leads to a (too big) flooding. In case the time is

exceeded, the level control and the related switchable sockets are immediately deactivated

and an alarm is triggered! The level control remains deactivated as long as the error is reset

or the ProfiLux 4 is restarted. If here 0 is set as duration, then the time monitoring is

deactivated.

EN 2017-02-06 64

ProfiLux 4 Programming Guide

6.1.3 Automatic Error reset

If you confirm “Reset Error?” with Yes then errors for this control will be reset automatically as

soon as the sensor signals no (or again) water contact (depends on the operation mode).

This function offers a higher degree of convenience because in case of the Automatic Top

Off, an error is automatically reset as soon as the missing water is re-filled manually). It does

however, carry a higher risk since the cause of error could persist further on. Therefore we

recommend full consideration if this function is to be used.

6.1.4 Sensor select

Here, you can determine which level sensor inputs are to be used by this level control.

2 sensors are to be selected for operating modes with 2 sensors.

6.2 Input

After selecting a level sensor input, you can set its behavior. Normally these settings need

not be changed.

6.2.1 Reaction Time

Set here the Reaction time of the level sensor input. It can be set between 0s and 240s

(Standard is 1s).

This feature is useful in instances where you may want to set a level sensor reaction delay. In

areas where there is frequent water surface agitation in the same area as the sensor, the

assigned switchable socket may turn on/off too often. ProfiLux 4 monitors if the signal (=

water there/not there) transmitted by the sensor is stable. Stable means in this case that a

change of the level has to remain constant at least for the set reaction time. Only if the level

is stable, the level control reacts. The reaction time shall be set sufficiently so that waves

don’t cause an activation of the regulation, but small enough that a reached level is not

recognized too late!

The Reaction time should be set high enough so that waves do not cause a response of the

control, but also small enough so that an attained level is not detected too late!

6.2.2 Input Inverse

Under certain circumstances it may be useful to invert the switching behavior of the sensor

(for example, if the sensor can only be installed upside down). Confirm Input invert? with Yes

then the sensor input is inverted.

EN 2017-02-06 65

ProfiLux 4 Programming Guide

Note

The flow sensor settings cannot be made via the ProfiLux 4 keypad, these settings can only be made using the GCC PC software.

6.3 Error Reset

If there is a timeout/overrun (socket with function Water switched on too long, see also under

Maximum switching duration) or the leakage monitoring system triggers an alarm, the error

status in the device must be reset. This also resets the alarm. As long as the error has not

been reset, the level control remains inactive!

6.4 Diagnostic

To facilitate the implementing of the level sensors, the menu item Diagnostic is available. The

current state of all level sensor inputs is displayed here. On contact with water (= sensor

active) the corresponding number of the sensor input is displayed.

The display of "1 4 8" means that sensor inputs 1, 4 and 8 signal contact with water.

Please note that a "contact with water" is also displayed when no sensor is connected. The

diagnosis is terminated with Esc.

6.5 Start Water Change

For all level sensor controls with the operating mode Water change or Water change & ATO,

you can start the automatic water change manually here. After you have answered safety

question with Yes, the water change starts.

7 Flow

ProfiLux 4 allows you to connect Flow sensors to our controller. These can be connected to

the permanently installed level inputs 1 or 2 and to ProfiLux Expansion cards with level inputs.

Up to 4 flow sensors can be connected.

Flow sensor settings cannot be edited via the ProfiLux 4 keypad, these settings can only be

made using the GCC PC software.

The following settings are available for each sensor:

EN 2017-02-06 66

ProfiLux 4 Programming Guide

Flow-Sensor model

Calibration value without bypass

2000 l/h

1.40 ml/Puls

5000 l/h

6.22 ml/Puls

9000 l/h

12.40 ml/Puls

7.1 Alarm Threshold

Here, you can enter a threshold of up to 65000 l/h. If the current flow exceeds this value, an

alarm is output. A threshold of 0 l/h switches off the alarm monitoring.

7.2 Calibration

Based on this value in ml/pulse, ProfiLux 4 calculates the current flow. The flow sensor used

determines this value:

If the flow sensor is operated in a bypass, the calibration value must be corrected

accordingly. Here is an example:

A 5000 l / h sensor is used in a bypass and only half of the water flows through the bypass.

Then enter a calibration value of 12.44 ml/pulse (double value of the standard calibration

value, a total of twice the amount of water flows).

GHL Control Center offers a tool to help you determine the correct calibration value.

7.3 Nominal Value

ProfiLux 4 can control a pump controlled via a 1-10V interface based on the measured flow (=

actual value) and a desired flow (= nominal value) so that the flow remains constant - if

technically possible.

A nominal value of up to 65000 l/h can be set.

Select a 1-10V interface which is to be used for the control of the pump (see also under

System -> 1-10 V interface). Depending on the difference between nominal value and actual

flow, the output voltage is increased or decreased.

7.4 Connected at Level-sensor

ProfiLux 4 needs to know at which level sensor input the flow sensor is connected. With Not-

enabled this flow sensor is inactive.

EN 2017-02-06 67

ProfiLux 4 Programming Guide

Timer

Then select the Number of the timer.

This switching output is controlled by the corresponding timer.

Dosing pump

Then select the Number of the dosing pump.

This switching output is controlled by the corresponding dosing pump control.

TIP

If you forgot your PIN

Switch off the device (disconnect the voltage supply), switch it on again (plug in the voltage supply again). Immediately, while the status and greetings screen is displayed, press the left arrow.

You will be asked: Are you going to delete the PIN?

After confirmation with Yes, the PIN is reset to factory default (0000 deactivated).

8 System

8.1 Factory Settings

After selection of this function you are asked if the factory settings shall be restored: Factory

settings now? If this is accepted, all settings are reset to their delivery status! The operating

hour meters are not reset.

8.2 PIN

A personal identification number (PIN) is used to protect the device against unauthorized

changes. Factory default is set to 0000. If the PIN is set to 0000, all changes can be made

without entering a PIN. As soon as the PIN is unequal to 0000, this PIN must be entered

before each setting. This also applies to the PIN change.

8.3 Socket Outlet Function

Here, the previously adjusted functions for connected powerbars or dosing pumps of the

first generation of GHL (hardware) are here assigned to the switch sockets/outlets

(hardware).

First, select the socket to which you want to assign a function. ProfiLux 4 can control a

maximum of 64 sockets.

You can assign the following functions:

EN 2017-02-06 68

ProfiLux 4 Programming Guide

Illumination

Then select the Number of the illumination.

With this you can assign a switching output to an illumination.

For a dim setting of the corresponding illumination of 0% it is switched off. For 1% to 100% it is switched on.

This function is intended to switch off dimmable light bars which do not have an internal voltage cut-off at 0% or to switch dimmable luminaires via the mains cable.

Dimmable light bars from GHL do not need an external switch-off and are directly connected to a permanent power supply as they are internally equipped with a shutdown. No switching sockets are required for the operation of dimmable GHL light bars!

Water fill (A+L)

Then select the Number respective level control.

The level control uses this switching output for switching solenoid valves or pumps when water is to be replenished.

This socket is used during automatic water change (AWC) and during auto top off (ATO).

With the following socket functions it is possible to switch different sockets for AWC and ATO (e.g. for osmosis- and salt-water).

Water fill (AWC/Water change only)

Then select the Number respective level control.

The level control uses this switching output for switching solenoid valves or pumps when water is to be replenished.

This socket is only used for AWC and not for ATO.

Water fill (ATO only)

Then select the Number of the respective level control.

The level control uses this switching output for switching solenoid valves or pumps when water is to be replenished.

This socket is only used for ATO and not for AWC.

Water drain

Then select the Number of the respective level control.

The level regulation uses this switching output to switch magnetic valves or pumps when water has to be drained.

Current pump

Then select the Number of the respective pump.

The current simulation switches this switching output on if the corresponding current pump is active.

Important hint: Each switching process means stress for the socket as well as for the pump. Because of this, the times in the current-modes Sequence, Surge or Random may not be set too short!

According to the connected load the sockets have a life cycle of up to 10,000,000 switching cycles!

EN 2017-02-06 69

ProfiLux 4 Programming Guide

Programmable logic

Then select the Number of the programmable logic.

The result of the corresponding programmable logic is output at this switching output. See also point Programmable logic.

Sum alarm

In case of any alarm this switching output is switched on.

Filter

Then select the Number of the respective feeding pause (1-4).

This switching output is generally permanently switched on, except during the feeding pause.

Always on

This switching output is always switched on.

Always off

This switching output is always switched off.

Thunder

This switching output is switched on for a short time (ca. 800ms) when the storm simulation generates a flash.

Thunderstorm

This switching output is switched on during a thunderstorm and can be used for instance to switch on a raining device in a terrarium.

Maintenance

Then select the Number of the respective maintenance (1-4).

This switching output is switched on during maintenance.

Water change

Then select the Number of the respective level control.

This switching output is switched on during the whole water change (during draining and refilling).

Variable Illumination

Then select the Number of the respective variable illumination.

Herewith you can assign a Variable illumination (see also Illumination ->Variable Illumination) to a switching output.

Digital input

Then select the Number of the digital input.

This switching output is switched on when the corresponding digital input is active.

Cooler

The temperature control uses this switching output to switch the cooler.

Heater

The temperature control uses this switching output to switch a heater.

Bottom heater

The temperature control uses this switching output to switch a bottom heater.

In addition, a switching output can be assigned to a control loop. For this purpose, one of the

available controllers (sensors) is to be selected, e.g. Temperature 1 or pH 1.

After the selection of the controller, which is to influence this switching output, the function

must be further specified.

For temperature controllers, these options can be selected:

EN 2017-02-06 70

ProfiLux 4 Programming Guide

PTC

This switching output is on when the temperature control wants to heat or cool (in both cases).

With this, you can make a here connected PTC which is already operated via a 1-10 V-interface, completely powerless if it shall neither be heated nor cooled.

In principle you can supply a PTC permanently with power and therefore it doesn’t need to be connected to a switchable socket, but you can save the standby-energy through the shut-off.

Alarm

In case of an alarm of this controller, the socket is switched on.

Control downwards

The control uses this switching output for the downwardsregulation e.g. to decrease the pH-value.

Control upwards

The control uses this switching output for the upwards-regulation to e.g. increase the pH-value.

Alarm

In case of an alarm of this controller, the socket is switched on.

Illumination

Then select the Number of the illumination.

Here the dimmable lamps are then connected – e.g. with dimmable ballasts or ProfiLux Moon. So it is possible to assign each

All other controllers can be selected under these options:

After selecting a function, the following settings can be made additionally:

 Blackout delay– for the time set here (0 to 60 minutes) the switching output remains

switched off in any case after the switch-on of the ProfiLux 4. This setting is useful if

this switching output switches a device which must first cool down before it is

switched on again, e.g. if the re-switching of a MH-lamp shall be delayed after a power

failure.

 Invert switching behavior – if this option is activated, then the switching output

behaves exactly inversely: if it shall be switched on, it is switched off and the other

way round. The inversion of the switching behavior is e.g. then useful if pumps or

magnetic valves shall be switched off instead of on through the level regulation.

8.4 1-10 V Interface

Each 1-10 V interface can be configured separately. ProfiLux 4 has six permanently installed

1-10 V interfaces L1 to L6 (two combined in one connection). With the PLM-2L4S or PLM-4L

expansion cards, the number of 1-10 V interfaces can be increased.

Once the interface has been selected, you can assign the desired and previously set function

to it.

EN 2017-02-06 71

ProfiLux 4 Programming Guide

illumination one arbitrary 1-10 V-interface.

Current pump

Then select the Number of the pump.

This interface is then used by the current simulation.

Always off

This interface has no function.

Variable Illumination

Then select the Number of the variable illumination.

Herewith you can assign a Variable Illumination (siehe auch unter Illumination ->Variable Illumination) to this interface.

Constant flow

Then select the Number of a flow sensor.

With this function this interface is able to control a variable-speed pump in order to obtain a constant flow, see also Flow.

Example: Temperature control

If the water temperature exceeds the set temperature, then a voltage is output that is proportional to the temperature control deviation.

Simply put: The warmer the more voltage.

With this it is possible to control a controllable cooler – e.g. our PropellerBreeze with the control electronics PropellerControl – and so to operate it as energy-saving and as low-noised as possible.

Furthermore you can assign a 1-10 V-interface to a control loop. For this you have to select

first one of the available controllers, e.g. Temperature 1 or pH-value 1.

The selected controller outputs then a voltage that is proportional to the control deviation (=

deviation from nominal value to actual value) at this interface.

After that you can set the Minimal and Maximal voltage of this interface. As a rule, the voltage

range is 1 V to 10 V.

It may be necessary to set the minimum voltage (at 1%) (Possible range: 0 V to 4 V). This may

be due to the following reasons:

 Not all tubes are equally suitable for dimming. Further information concerning the

dimming suitability can be obtained from the tube manufacturer. Most of the

problems occur in the lower dimming range (up to ca. 10%). Here it can happen that

the tube simply switches off after a certain time (mostly few minutes). Solution:

Increase of the Minimal voltage.

 Not all dimmable ballasts behave in the same way. The lower dim setting should

normally be reached at a voltage supply of 1V, full light intensity at 10V. We have

ProfiLux 4 Programming Guide

Tip

To achieve an optimal light intensity course, the control voltages should be adapted to the connected lamp, i.e. minimal light intensity and lower voltage supply as well as maximal light intensity and upper voltage supply should fit exactly together.

To achieve an optimal course of the dimming you can test in the menu Manual Illumination, if for the lower dimming values the light intensity changes or if the lamp shuts off and for the upper dimming values if there are still differences in the light intensity that can be seen. If necessary, the Minimal and Maximal voltage have to be changed and tested again.

noticed that the light intensity doesn’t change anymore for some ballasts for a voltage

supply under 1.5V, for other ballasts the dimmable range goes to ca. 0.8V.

 The current pump stops although the set current speed is >= 1%.

The maximal voltage (at 100%) has to be set between 4.5V and 10V, to solve for example the

following problems:

 For certain dimmable ballasts there is no further light intensity change visible

between 9.5 V and 10 V.

 The current pump operates with full power already at 8 V.  The moonlight is too bright at 10 V

8.5 Program LED

These functions are used to reprogram a connected LED light from GHL (Mitras-Simu-Stick).

During programming, only the lamp to be programmed must be connected! The setting is

stored in the LED light (even in the event of a power failure).

Swap channels – the channel assignment in the lamp is swapped. As a default setting

ProfiLux Moon reacts to illumination 1 (resp. 3) and ProfiLux Sunrise to 2 (resp. 4). After the

channel swap the lamp behaves exactly inversely. This makes e.g. then sense, if a moon light

and a commonly dimmable light bar shall be connected via a Y-plug at the same port of the

ProfiLux.

Lightning mode – here you can set if the flash light (only for ProfiLux Simu) shall react to All

flashes, to Flash 1 or to Flash 2. If only one ProfiLux Simu is connected, you should choose All

flashes. If 2 ProfiLux Simu are connected, then one should react to Flash 1, the other one to

Flash 2. This produces a nice effect, since for a flash generated by a ProfiLux 4 not always

both flash lights react but it is determined at random where the flash is generated.

Note

The following settings can only be made directly on ProfiLux 4!

Moon-Color - this setting defines if your moonlight shines Deep blue, Light blue or Blue white.

This programming is only possible for the LED-lamps ProfiLux-Simu and ProfiLux-Moon. This is

NOT possible for: Mitras-Simu-Stick, ProfiLux-Simu-DB, ProfiLux-Simu-BW, ProfiLux-Moon-DB,

ProfiLux-Moon-BW and ProfiLux-Sunrise!

8.6 Communication

Here you can make all communication-related settings.

 Device address – The computer can be accessed from the PC-program GHL Control

Center under this address.

If multiple computers are networked, they must have different addresses!

Otherwise there is no need to change this setting.

If there are more communication interfaces, select one of them. All subsequent

settings refer exclusively to the selected interface!

 Baud rate – The connection speed of the previously selected interface is set here

(standard 9600 baud).

The connection speed must match the connection speed of the receiver (e.g., PC with

GHL Control Center). If the external display unit ProfiLux View or the SMS module is

connected, then 9600 Baud must be set!

Increasing the connection speed is useful when the connection is short and interference-

free. For transmission problems, e.g. for long and interference susceptible lines, it may be

useful to reduce the baud rate.

8.7 Alarm

The operating mode of the alarm buzzer can be set here.

 Buzzer off – even in the event of an alarm the buzzer remains off  Buzzer on – buzzer gets active in the event of an alarm, regardless of the clock time  Buzzer at set time – buzzer gets active only to a determined time. Set the time range in

which the buzzer is allowed to be active in the event of an alarm.

ProfiLux 4 Programming Guide

Note

Overall 32 sensors (sum of actual and virtual probes).

8.8 Virtual Probes

Under this menu item, you can manage so-called Virtual probes.

What are Virtual probes?

Sensors for detecting different values (for example, temperature, humidity) can be

connected to ProfiLux 4 or to corresponding Expansion Cards. To each of these sensors a

control loop is assigned whose parameters (nominal value, hysteresis, nocturnal change, etc.)

can be set. The control of a sensor switches the related switchable sockets (e.g. pH upwards

and pH downwards for the pH-value-control or Heater, Bottom heater and Cooler for the

temperature control).

It may be necessary to assign several, differently set control loops to the same sensor. One

example would be a temperature control where bottom heater and heater shall be operated

considering a nocturnal change, but the cooling shall not be influenced by the nocturnal

change (since you don’t like to have an active nocturnal change)

The solution is to create a "copy" (= virtual probe) of the actually existing sensor. This virtual

probe and its associated control loop can be used just like a "normal" sensor. The actual

measured value of the virtual probe is, of course, always equal to the measured value of the

"original sensor". In addition, a virtual sensor cannot be calibrated.

Apart from the simple copy of a sensor, a virtual probe can also be generated from 2 original

sensors. An average value from the current values of the two original sensors is then

calculated.

This has two advantages: Firstly, it can be useful for a large amount of water (for example, a

pond) to be measured at two different locations and form an average value; on the other

hand, both original sensors can be monitored for too great a deviation. A too large deviation

could indicate a fault, and the display of an alarm is then possible.

In the Virtual probes menu, you have the following selection options:

8.8.1.1 New Virtual Probe

A new virtual sensor can be created here. First select the type of the virtual sensor:

EN 2017-02-06 75

ProfiLux 4 Programming Guide

Note

After creating a virtual probe, the sensors of the corresponding type are renumbered.

In the ProfiLux 4 menus, you can distinguish virtual sensors from actually existing sensors by fully writing the name of virtual sensors (e.g., PH-VALUE

1).

 Copy - Now select the original sensor from which a "copy" is to be generated. The

current value of the virtual probe always corresponds to the current value of the

original sensor.

 Average - Now select sensor 1 and sensor 2. The current value of the virtual sensor

always corresponds to the current mean value from both original sensors. The alarm

settings can also be used to specify a comparison alarm (see Sensor settings ->Alarm).

After storage, a virtual sensor (e.g., TEMPERATURE 2) is available. The corresponding settings

(nominal value, hysteresis, etc.) are copied from the original sensor.

8.8.1.2 Delete Virtual Probe

A virtual probe can be deleted here.

8.9 Digital Powerbars

Here, our digital sockets or dosing units can be managed.

Firstly you will be asked Use digital powerbars at S1-S4? (This also applies to dosing units that

you want to connect digitally). If you have selected Yes, then the socket control output S1-S4

is set to digital data transfer so that at this socket, a communication with digital powerbars

and dosing units is possible.

If digital sockets are to be used, the following options can be selected:

 No action – No further action is performed in the following.  Set initial state - (for dosing pump units this function is not available) With this, you

can set the states of the single sockets of a digital powerbar immediately after supply

voltage has appeared. These states are also restored if the communication between

ProfiLux and the powerbar is – due to any reasons – missing longer than 60 s, e.g. in

case of a removed control cable or a defect of the ProfiLux 4. The digital powerbar

monitors permanently if it still receives commands from the ProfiLux 4. It is for

example possible that you set your digital powerbar in a way that in case of a

malfunction, the socket for the filter will be on and the socket for the heater will be

EN 2017-02-06 76

ProfiLux 4 Programming Guide

Note

The setting Use digital sockets only affects S1-S4!

All other connections for switch sockets (for example, S5-S8) are also suitable only for conventional switch sockets, and these connections cannot be changed.

If the option Use digital sockets was activated, no conventional switch socket can be controlled with S1-S4.

Mixed operation of digital sockets (on S1-S4) and conventional sockets (on the other switch sockets, for example S5-S8) is possible.

If the switching state or the numbering is to be set, only one single digital powerbar resp. dosing pump unit may be connected. If several devices would be connected during the programming, then all would overtake the new programming!

The numbering of powerbars and dosing pump units is freely selectable (see above Set numbering).

In contrast, the numbering of conventional powerbars is determined by the port at which they are connected.

Sockets of a bar connected to S5-S8 have, e.g. always the numbering 5 to 8. In this case, care must be taken that no duplicate number assignments result!

The set numbering and output states are permanently stored in the digital power bar and are thus retained even if they are not connected to mains voltage.

off. So the water circulation is furthermore guaranteed, an overheating is at the same

time impossible.

 Set numbering - With this, you assign numbers to the sockets of the digital powerbar

(resp. the pumps of the dosing unit). The first socket of the powerbar (resp. pump of

the dosing unit) receives the set start number, the next socket (resp. pump) this

number + 1, etc. If e.g. 10 is set as first number, then the sockets of the powerbar

have the numbers 10, 11, 12, 13, 14 and 15. The pumps of a dosing unit would have in

this case the numbers 10, 11, 12 and 13. Then the set powerbar functions refer to

these numbers, see also System->Socket outlet function. Start numbers between 1 and

19 can be assigned.

Note

This menu item appears only if you have installed a DALI interface.

8.10 Configure PTC

If you use our ProfiLux Temperature Control (PTC) cooling and heating unit, you can perform

one of the following actions:

 Swap channels – If PTC reacts to an odd channel (L1, L3, etc.), it will react to a straight

channel (L2, L4, etc.) after the channel change and vice versa.

 Silent Mode on – The fans are throttled and therefore quieter, the efficiency drops

somewhat.

 Silent Mode off – The fans are operated normally.

8.11 DALI

DALI (Digital Addressable Lighting Interface) is a standardized digital interface for the

connection of corresponding devices (e.g., DALI-balasts) via a data bus. Via only one control

line, up to 64 devices can be accessed individually, the devices are distinguished by their

address.

ProfiLux 4 numbers the DALI devices on command fully automatic. You only need to set

which device is to respond to which lighting.

If a DALI interface is available, you can select the following functions in the DALI menu:

 Minimal dim-level DALI – DALI devices have a minimum physical dimming setting

which is specified by the manufacturer. In order to achieve an optimum dimming

sequence, you should set this value according to the devices used. Factory setting is

85, which corresponds to the value of Osram DALI-ballasts. Values between 0 and 254

can be set.

 New numbering – Here, all connected DALI devices are assigned a new long address

(between 0 and 16777215) firstly. Then ProfiLux searches for all connected DALI

devices and assigns short addresses between 0 and 63. When ProfiLux has finished

numbering, the number of devices found is displayed. If not all devices have been

found, even though the cabling is correct, then start New numbering again.

No action

This digital input does not have any special function.

Water change

This digital input starts the automatic water change. A second switching impulse interrupts the automatic water change.

Maintenance

This digital input starts the maintenance mode. A second switching impulse terminates the maintenance mode.

Feeding pause

This digital input starts the feeding pause. A second switching impulse terminates the feed pause.

Storms

This digital input starts a thunderstorm.

The New numbering must only be carried out if you have connected new devices to the

DALI bus.

 Assign illumination – This allows you to assign illumination to each connected DALI

device. This means that the brightness is set in the corresponding DALI device,

depending on the assigned illumination. After selecting this function, you can use

arrow up/ down to select which device you want to assign a illumination to. The

currently selected device is then operated with a brightness of 100%, all other devices

(or its associated lamps) are switched off. Confirm the selection with RETURN, then

you can Assign illumination? (arrow up/down, then RETURN again). After a short wait,

you can make another illumination assignment. When finished, press ESC.

8.12 Digital Input

If an Expansion card PLM-ADIN is available, there are 4 digital inputs as well as 2 analog

inputs. The state of a digital input can be used to directly switch a switch socket (see also

under System ->Socket outlet function) or to start or terminate a special function.

After selecting the digital input, its function can be set.

9 Programmable Logic

ProfiLux 4 offers a wide range of settings for almost every application. However, there may be

situations where the user needs specific functions that are not covered by the standard

functions of the ProfiLux 4. An example: During the feed pause, the heating should always be

off, otherwise it should be temperature-dependent.

With the help of the programmable logic, the user can create a function for switching the

corresponding socket.

Compared to the other functions of the ProfiLux 4, Programmable Logic requires basic

knowledge of Boolean logic. Therefore, the corresponding settings cannot be changed on the

ProfiLux 4 itself, but only via the PC operating program GHL Control Center.

For more information about Programmable logic, please visit our website.
