A separate product database for each device type is available for download on the homepage. The
imported product database must match the actuator used.

2.2 Warnings & Instructions for Installation

When installing and connecting dimming actuators, ensure that they are properly connected in
accordance with the manufacturer's information in order to avoid damage to the devices and the
connected loads. Important warning and installation instructions are compiled in this chapter 2.2 and
in chapter 8.3. If, after reading the manual, there are still uncertainties, contact the customer service
before installation

See assembly instructions in chapter: 8.3 Assembly

2.2.1 Warnings

Dimmer for conventional loads:

Switching off the load at the secondary winding is forbidden! Because of resonance

phenomena, stress intensifications up to 1000V can appear which causes the damage of

the dimming actuator. Minimal and maximal loads must be met. The load contains of the

transformer and the lamp. In cases of doubt, the primary current consumption must be measured.

Adjustment of the operating mode:

Possibilities of destroying for dimming actuator and connected load, if connected load and

adjusted load does not fit to each other!

To avoid this case, check the adjusted dimming mode at changing the connected load as
well the connected load at changing the dimming mode.
At changing the load, the load circuit must be unlocked and the adjusted parameter must be
checked.

Mixed Loads:

Possibilities of destroying for dimming actuator and connected load, if mixed loads are

connected!

Capacitive loads, e.g. electronic transformers, and inductive loads, e.g. inductive

transformers, must not be connected together at one channel.

2.3 Structure & Handling

The dimming actuator has a programming button and a programming LED, which indicates that the
programming button has been pressed. Bus communication can be established with the bus
connecting terminal.
Each channel has a separate supply line (see connection diagram). The neutral conductor must be
connected separately for each channel and must not be bridged across the device, see 2.2.2
Connection diagram
The dimming actuator has one green and one red status LED per channel. The green LEDs indicate a
switched output. The red LEDs per channel are the LEDs that are responsible for the alarm function.
These LEDs indicate the five different alarms with different lighting behaviour. An overview of the
display behavior of the LEDs can be found under "2.5 Types of alarms and their correction".
The manual operation function is also described in the following section.

2.4 Display LEDs & manual operation

The individual channels can be switched on and off as well as dimmed up and down manually using
the manual control (see picture above). A selected channel is indicated via the status LEDs. These
LEDs can indicate the following states:

Table 1: Display behavior of the green LED

The selected channels can be switched or dimmed via the channel keys. A short press on the channel
key switches the channel on/off. With a long keystroke the selected channel can be dimmed. As long
as the channel button is pressed, the channel dims up/down. The dimming process is only ended
when the channel reaches 100% or when the button is released.

2.5 Types of alarms and their correction

Every channel contains further of a red alarm LED. According to the LED behavior, the following types
of alarms are indicated:

Table 2: Display behavior of the red LED

To eliminate the errors, certain actions must be done, depending to the error type, to eliminate
them. These actions are described below:

• Dimming actuator is in parallel operation and one channel has no voltage; LED long on,

short off

o Establish voltage supply for the channel according to the circuit diagram.

• No power supply at the output, LED lights red

o Establish voltage supply for the channel according to the circuit diagram.

• Wrong load at output, LED flashes 1x

o Select the correct load for the channel in the ETS software, pay particular attention

to the distinction between phase angle and phase section, and reprogram the
dimming actuator.

• Dimming actuator reports overtemperature, LED flashes 2x

o Dimmaktor ausschalten bis sich der Aktor abgekühlt hat.

• Short circuit/overload at output, LED flashes 3x

o Remove short circuit/overload at the output. The fault can be eliminated by

switching OFF/ON or manual reset. (Prog. Activate mode and press channel key
within 5s

Attention: The alarm LEDs always remain on until the next switching or restart and are not
deleted automatically!

2.6 Functions

Depending on the device version, two to four channels can be activated or deactivated individually. If
one channel is activated, the channel can be further parameterized according to its use. The
parameterisation options are identical for all channels of a dimming actuator. The dimming
behaviour of the output is described by the selected load type.

• A variety of output functions

As standard, the basic functions switching, relative dimming, absolute dimming, status,
staircase lighting, disable function, scene and automatic are available in the dimming
actuator for each output. Switch-on/switch-off delays and various dimming speeds can be set
here. Furthermore, central objects and alarm objects for overcurrent and overtemperature
are also available.

• Extensive dimming functions

For dimming the lighting you can choose between 5 different dimming curves linear, LED A,
Led B (recommended), LED C and logarithmic. The global dimming speeds are used to set the

on/off speeds for day/night operation and the dimming speeds for relative and absolute
dimming for all channels. If a different dimming speed is required in a channel, the
parameter can be set individually. The dimming speed can be changed specifically for this
channel.Furthermore, the dimming speed can be set for each scene and a dimming speed
can also be indirectly defined under Transition time to next step.

• Time dependent dimming

The individual channels of the dimming actuators can be dimmed according to the time of
day. For this purpose, the value Time-dependent brightness is selected when the switch-on
behaviour of the channel is parameterised. Ten times with different brightness values are
available, for example from 06.00 in the morning with 50%, above 08.00 with 100% and from

20.00 with 80% down to 23.00 to 15%. If the lighting is switched on at 07.00 hours, it starts at
75%. By means of the ten times, an individual day programme can be put together and the
lighting automatically always has the right brightness at the right time. Application for
example in the bathroom, at night between 00.00 and 05.00 o'clock the light switches ON
with only 30% if required.

• Single operation / parallel operation

The outputs of the dimming actuator can be wired differently, see 2.2.2 Connection diagram.
For the sake of simplicity, please refer to the options in the table:

• Long Frame Support

The dimming actuators support the long frame support. When programming via ETS5, Long
Frames (longer telegrams) are sent. These contain more user data per telegram, which
significantly reduces the programming time of the LED controllers with the ETS5. You need a
programming interface that supports the transmission of long frames. MDT offers the
programming interfaces IP Router SCN-IP100.03, IP Interface SCN-IP000.03 and USB Interface
SCN-USBR.02

2.8 Commissioning

After wiring the device, the physical address is assigned and the individual channels are
parameterized:

(1) Connect the interface with the bus, e.g. MDT USB interface
(2) Set bus power up
(3) Press the programming button at the device (red programming LED lights))
(4) Loading the physical address from the ETS software via the interface (red LED turns off as

soon as this is successfully completed)

(5) Loading of the application with requested parameterization
(6) Connect the mains voltage and switch on
(7) The dimming actuator needs approx. 10 sec. until it is ready for operation.
(8) An automatic load test is performed when the unit is started. This test may cause the lamp to

flash briefly.

(9) When the device is ready for operation, the desired function can be checked (also possible

with the ETS software).)

4.2 Day/Night Object and Location Determination for Time/Date

The following settings are available for the day/night object and time:

Figure 5: Settings - Day/Night and Time

The day/night object is used in the various application settings to create a special switch-on
behaviour for day/night or to reduce/increase minimum/maximum brightness. The parameter
"Toggle light day/night" can be used to define whether the day/night switch has a direct influence or
not until the next switch-on. If the switch-over is only activated at the next switch-on, the change of
the corresponding values will only be accepted at the next switch-on. For this purpose the channel
has to be switched once to 0% / Off. If the changeover is to have a direct effect, where the minimum
/ maximum values for brightness are adjusted directly and if the last switching command was an ON
telegram, the channel is also dimmed according to the switch-on behaviour
The parameter "Energy saving mode, switch off LEDs on the device after" can be used to deactivate
the LEDs on the device after a certain time. Pressing a key reactivates the LEDs for the set time until
they are deactivated again.
The location determination is relevant for the calculation of sunrise and sunset times, which can be
used in time dependent dimming.
In principle, the receiving time of a master always continues to run internally. In the event of a time
changeover after the Central European time changeover for summer time, the device can carry out
the time changeover independently, if this is desired via the parameter "Automatic changeover of
summer time".

4.3 Use of the channels

The following possibilities for parameterization are available for setting the channels
(here AKD-0401.02):

Figure 6: Settings - Use of the channels

Via the parameter " Setting channels" you can select whether channel pairs (A+B and C+D) should be
connected in parallel. By connecting 2 channels in parallel, the permissible total current is doubled.
If the channels are connected in parallel, they can only be parameterized together. However, it is also
possible, for example, to connect channel A+B in parallel and operate channel C/D individually.
The following settings are possible:

• individually (each channel is controlled individually)

• parallel channel A+B and individual channels C,D

• parallel channel A+B and channel C+D

• single channels A,B and parallel channel C+D

However, it is still absolutely necessary to bridge the channels at the terminals with as short
connecting cables as possible.

Note: The settings for the 2-fold actuator are reduced accordingly to A and B individually or A/B in
parallel.

4.4 Operation / Basic functions

4.4.1 Operation / Basic functions

The basic functions of the normal dimming / switching function are divided into three areas:
switching, relative dimming and absolute dimming. As soon as a channel is activated, the
communication objects for the basic functions are displayed as standard.

4.4.1.1 Switching

The channel can be switched on or off with the switching command. In addition, there is a message
object which indicates the current switching state of the output. This object, state On/Off, can be
used for visualisation purposes. If the dimming actuator is to be switched via a binary input, using the
toggle function, the object has to be connected to the status object of the binary input, "Value for
toggle".

Table 7: Communication objects - Switching

4.4.1.2 Dimming relative

Relative dimming allows continuous dimming. Thus, the connected lamp can be dimmed evenly from
0 to 100% upwards, or dimmed from 100 to 0%. The relative dimming can be stopped at any state.
The behaviour of the dimming process can be individually adjusted via additional parameters, such as
the dimming speed

Table 8: Communication objects - Dimming relative

4.4.1.3 Dimming absolute

A discrete brightness level can be set by absolute dimming. By sending a percentage value to the 1­byte "Dimming absolute" command, the output is assigned a specific brightness value.

4.4.2 Load Type

For the channel to work properly, the correct load type has to be set for the channel.

Figure 7: Selection - Load type

The following settings are available for selection:

[default value]

RC ohmic load (trailing-edge)

• L inductive loads/wound tranformers (leading-edge)

• LED 230V old generation (leading-edge)

Selection of the load type
connected to the respective
channel

• LED eco/universal (trailing-edge)

• LED/Halogen with external ECG (trailing-edge)

Table 10: Settings - Load type

For the dimming actuator to dim the channel properly, the connected load type has to be selected in
the parameterisation. If the selected load type does not match the connected load type, the channel
outputs an error message via the "Overload" object or via the LED on the device itself. The channel
does not switch as long as an error message exists. If, after the "Load error" error message, the load
is subsequently replaced by hardware, the "Overload" error message remains nevertheless until the
channel receives a new switching command and the load detection is restarted.
When selecting the load type, the distinction between phase angle and phase section is particularly
important.

Table 13: Settings - Dimming curve

Different luminaire types have different dimming characteristics. However, since a linear dimming
behaviour is usually desired, it is necessary to adapt the dimming characteristic, according to which
the channel dims, to the lamp used.

4.4.4 Limiting the dimming range of the lamp

If the technically possible dimming range (1-100%) is to be
limited to a smaller value, this is possible by setting a
minimum and maximum brightness value for each channel
individually. If the dimming range is limited, the channel
will only move within the set limits. This also has
consequences for other parameters: if, for example, a
maximum brightness value of 85% is set and a switch-on
value of 100% is selected, the channel will also switch on at
the highest value of the maximum permissible value of
85%. Exceeding this value is no longer possible.
The setting of a dimming range is especially useful if
certain values should not be reached for technical reasons.

Figure 10: Limitation of dimming range

Example:

minimum brightness value = 25%, maximum brightness value = 85%, switch-on value = 100%

• Telegram value On --> brightness value 85%

• Telegram value 50% --> brightness value 50%

• Telegram value 95% --> brightness value 85%

• Telegram value 15% --> brightness value 25%

• Telegram value Off --> brightness value 0% (Off)

The staircase lighting function allows the channel to be switched off after a certain time value. To be
able to parameterise the staircase lighting function further, it must first be activated. Activation is
done in the tab for the respective channel:

The duration of staircase light indicates how long the channel should remain switched on after an
ON telegram. The channel switches off automatically after the staircase lighting time has elapsed.
The parameter Extend staircase timer can also be set for the staircase lighting process which
determines whether an extension of the staircase timer is possible and whether the time is restarted
or added up. If the staircase lighting is controlled absolutely/relatively via dimming, the time is not
added up. The Manual switching off parameter can be used to decide whether an OFF telegram
leads to an immediate switch-off of the channel. The Prewarning function can be used to dim the
lighting after the staircase timer has ended. This is used to warn that the lighting goes out after the

Prewarning duration has expired. The lighting is thus dimmed down to the set Value for dimming
down after the staircase lighting duration has expired and remains switched on for the set

prewarning duration after this value is reached. All other actuator controls, e.g. via the switch object,
trigger "duration" commands or interrupt the staircase lighting time.

The switch-on delay and the switch-off delay can be used to delay the switching telegrams of the
dimming actuator. The delay can occur both during the switch-on process (ON delay) and during the
switch-off process (OFF delay). Both functions can also be linked together.

Only active with setting: Change
switch-on value via object!

Via the parameter "settable activation value" each channel receives a fixed activation value. The
switch-on value covers the entire technically possible range from 0.5-100%. If the dimming range is
limited, the dimming actuator switches on at least at the minimum brightness value and at most at
the maximum brightness value; irrespective of the set switch-on value.
The "Last brightness value (Memory)" parameter causes the dimming actuator to save the value last
reached before switching off and to call up this value again when switching on again. If the memory
function is activated for day and night is not set to "like day", the last value is only saved if day is
active.
The "Change switch-on value via object" function can be used to specify a new switch-on value via
an object (No.18). Using the "Reset object value" parameter, the changed value can be reset to the
parameterised switch-on value (device restart or day/night switchover) or it can be retained.
In addition, the channel can start time-dependent light-level control by switching on. The switch-on
behaviour can be parameterised separately for day and night

follows:

• 1 Bit Object

It can be freely determined whether the channel is to be locked/unlocked with the "0" or the
"1". The actions for locking/unlocking can also be set.

• 2 Bit Object

By means of 2 bit forced control, the channel is disabled at object value forced ON (11). With
object value Override end (00), the channel is unlocked. The action for force OFF (10) can be
set to "Lock OFF" or "No change.

• 1 Byte dimming value

By means of a 1-byte object, the channel is set to the corresponding value via a dimming
value >0% and disabled. The value 0% unblocks the channel again.

The following actions can be defined for locking (no action can be defined for the locking function via
1 byte object, since the channel is set to the transmitted value here) and unlocking:

• Deactivation

The channel is switched off.

• Activation value (Day/Night)

The channel is set to the currently valid switch-on value (depending on whether day or night).

• Hold value / no change

The channel remains in its current state.

• Brightness value

A freely adjustable brightness value (0-100%) is controlled.

• Update value

The value of the channel is updated, i.e. it retrieves the actions that were sent during the
lockout.

• Value before locking

The channel restores the value it had before the lock function.

• Time dependent dimming

The channel starts the time dependent dimming.

• Disable time dependent dimming

The channel switches off the time dependent dimming.

4.4.12 Scenes

If room functions of different trades (e.g. lighting, heating, roller shutters) are to be changed
simultaneously at the push of a button or with an operating command, the scene function is a good
choice. By calling up a scene, you can, for example, switch or dim the room lighting to a desired
value, move the blinds to a desired position and turn the slats, set the heating control to daytime
operation and switch on the power supply for the sockets in a room. The telegrams of these
functions can have not only different formats but also values with different meanings (e.g. "0" for
lighting OFF and for OPEN blinds). Without the scene functions, you would have to send a separate
telegram to each actuator to obtain the same setting
The scene function of the dimming actuator can be used to integrate the channels into a scene
control. To do this, the value has to be assigned to the corresponding memory location (scene A-H).
Up to 8 scenes can be programmed per channel. If the scene function is activated in the channel, the
associated sub-menu appears. The individual scenes can be activated here and values, scene
numbers and the ON/OFF memory function can be set.
Scenes are activated by receiving their scene number on the scene object. If the save function is
activated in the scene, the current channel values are saved with the object value of the scene. The
communication objects of scenes always have a size of 1 byte

control point. Depending on the
"Switching times" parameter, fixed
times or times depending on
sunrise/sunset can be set here

for the respective time

Due to the time dependent dimming a dimming process can be realized over a whole day. The
channel adjusts the brightness for this channel depending on the time. Time-dependent dimming can
be carried out either on the basis of sunrise and sunset times (which the dimming actuator calculates
itself by entering the time/date) or on the basis of fixed times. For this purpose, 10 control points
(time + brightness value to be controlled) can be defined. The set brightness is then reached at the
set time. The dimming actuator interpolates between the control points, i.e. if, for example, a
brightness value of 50 % is set for 8:00 and a brightness value of 75 % for 10:00, the channel will dim
slowly from 50 % to 75 % within these 2 hours.
If the brightness value is changed during time-dependent dimming via relative/absolute dimming
commands, time-dependent dimming is interrupted. In the Brightness release time parameter, you
can set whether and after what time the brightness is automatically reset to the parameter value. If
the release time is active, time-dependent dimming can be stopped via the object Time-dependent
dimming - switching, scene or bit scene

The active power measurement enables the output of the real active power by measuring current
and voltage simultaneously. The output value is thus no longer a "theoretical" power at nominal
voltage, but the actual power. The measured power of the actuator channel can be output via object
Active power and thus display the currently connected load.
