5.1.3. PRELIMINARY CONFIGURATIONS

After making the electrical connections, simply power up the device to start operation. At first start-up, Eliwell recommends that you:

1. make sure the instrument is powered (green POWER SUPPLY icon on)

2. make sure the display is working: when the controller is powered up it performs a lamp test, during which time the display and icons will blink for several seconds to ensure that they all function correctly

3. make sure there are no active alarms (ALARM / HACCP ALARM icon off and labels E1, E2, E3 not displayed).

4. configure the main parameters listed in the USER menu to suit your requirements, as described below

5.1.4. OPERATION IN DEFAULT CONFIGURATION

The instrument is configured for negative cold. For positive cold, disable the evaporator probe Pb2 (set H42=n) and relay OUT3 (set H23=6) to prevent continuous ventilation.

COMPRESSOR

The compressor is active if the cold room temperature measured by Pb1 exceeds the value of SEt + diF. The compressor stops if the cold room temperature detected by Pb1 falls below the SEt value. The instrument includes compressor on/off protection.

DEFROST

Defrost is by means of electric heaters (parameter dty = 0) and the time counter is always active with the instrument switched on (dCt=1).

Manual defrost

Manual defrost is activated by pressing and holding the ESC key (A) If conditions are not right for defrosting, (e.g. the evaporator probe temperature is higher than the defrosting end temperature) or parameter OdO≠0, the display will blink three times to indicate that the operation will not be performed.

Default Defrost settings dit = 6 hours. interval between 2 defrost cycles dSt = 6.0 °C. defrosting end temperature. set by Pb2 The Defrost cycle may terminate due to a timeout based on the parameter dEt (default 30 min).

EVAPORATOR FANS

The OUT3 relay is configured as the fan relay and is activated when required, according to the delay and parameter settings.

Default fan settings dt = 0 min. dripping time dFd = Y. Fans off during defrosting

LIGHT (EWRC 500/5000)

The light is activated by pressing and holding the LIGHT key (F) As digital input DI1 is configured as door switch, relay OUT4 (light) is activated when the door is opened. The light also switches on with the instrument in stand-by.

ALARM relay (EWRC 500/5000)

Relay OUT5 is configured as alarm relay and is activated in the case of alarms, according to delays and parameter settings.

5.1.13. Modifying a parameter

The User parameters USr are not divided into subfolders. They are always visible by default (access password PA1 is not enabled by default). The same parameters are also visible in the respective folders ‘Compressor’, ‘Fans’, etc. within the Installer parameters menu InS. The password is enabled (PA2=15) by default.

NOTE: It is advisable to switch the device off and on again each time the configuration of the parameters is changed, so as to prevent malfunctions affecting the configuration and/or the current timings.

How to modify a user parameter

Instructions are provided below on how to modify a User parameter The same procedure applies to Installer (inS) level parameters. Let us take the dit parameter as our example. There are no sub-folders at User level. At Installer level the parameter is in the folder containing dEF defrost parameters. We will now show how to change the value from 6 hours to 8 hours.

6. FUNCTIONS AND REGULATORS

This chapter describes the various functions of the devices.

NOTE: some functions may not be available in certain models.

6.1. SETTINGS

6.1.1. PROBE SETTING AND CALIBRATION

EWRC 300/500/5000 NT have 3 configurable NTC/PTC inputs (Pb1...Pb3).

The temperature probes (Pb1...Pb3) must all be the same type and should be configured via parameter H00, visible at User level (USr) or inside folder CnF, Installer level (inS)

• H00 = 0 if using PTC probes

• H00 = 1 if using NTC probes (Default)

After installation, the values read by the probes can be corrected/calibrated using the following parameters:

• CA1: probe 1 offset. Positive or negative value to be added to the value read by Pb1 (Range: -30.0...30.0)

• CA2: probe 2 offset. Positive or negative value to be added to the value read by Pb2 (Range: -30.0...30.0)

• CA3: probe 3 offset. Positive or negative value to be added to the value read by Pb3 (Range: -30.0...30.0)

6.1.2. DISPLAY SETTINGS

At User level (Usr) or inside the diS folder at Installer level (inS) you will find the parameters used to set the temperature readout, decimal point usage, unit of measure and display during defrost.

• ndt: (USr/inS) enables/disables decimal point display (with resolution of one-tenth of a degree; e.g.: 10.0°C) Display with decimal point is only possible within the range of values from -99.9°C to 99.9°C

• ndt = y  displays read values with decimal point (default);

• ndt = n  displays read values without decimal point

NOTE: enabling/disabling the decimal point only affects the on-screen display of values.

The controller will continue to perform calculations with decimal point.

• ddL: (USr/inS) sets the type of display during and up to the end of defrost

• ddL = 0  displays the probe value (default)

• ddL = 1  continues to display the value read by the probe at the start of defrosting

• ddL = 2  displays the fixed label dEF

• dro: (inS) sets temperature display to °C or °F.

• dro = 0  display in °C (default)

• dro = 1  display in °F

NOTE: switching between °C and °F DOES NOT modify the values of temperature parameters (e.g. setpoint=10°C becomes 10°F). This means that the maximum and minimum limits of parameters as absolute values

are the same for both units of measure and hence the ranges are different.

• ddd: (inS) establishes the value to be shown on the upper display. All other display and adjustment modes are the same.

• ddd = Set  displays the Setpoint value

• ddd = Pb1  displays the values read by Pb1 (default)

• ddd = Pb2  displays the values read by Pb2

• ddd = Pb3  displays the values read by Pb3

6.2. FUNCTIONS

6.2.1. UPLOAD, DOWNLOAD, FORMAT

Description

The Unicard/CopyCard must be connected to the (TTL serial port and allows the rapid programming of instrument parameters.

DOWNLOAD from reset operating mode: at power-on, if the Unicard/CopyCard is inserted in the device, the controller automatically downloads data.

After connecting the Unicard/CopyCard with the instrument switched off and on completion of the lamp test, one of the following labels will be displayed:

• dLY if the operation was successful

• dLn if the operation was not successful

After about 5 seconds, the display will show the probe or set point value, depending on the default settings.

NOTE: once the download has been completed successfully, the controller will start to work with the new map loaded.

Operating mode: access “Installer” parameters by entering the password “PA2” if enabled (PA2≠0), scroll through the folders using UP & DOWN until the folder “FPr” appears. Select it using SET, scroll through the parameters using UP & DOWN and then select one of the functions by pressing SET:

• UL (Upload): With this function, the programming parameters are uploaded from the instrument to the card. If the operation is successful, the display will show “y”, otherwise it will show “n”.

• Fr (Format): This command is used to format the copy card (which is necessary when using the card for the first time).

NOTE: the use of the Fr parameter deletes all data present and this operation cannot be reversed.

• Download: Connect the Unicard/CopyCard when the instrument is switched off. At power-on, data will automatically start downloading from the Unicard/CopyCard to the instrument. At the end of the lamp test, the display will show “dLy” if the operation was successful and “dLn” if not.

NOTE: before Uploading or Downloading a map, make sure that communication with the supervisor (PC with Televis, TelevisGo system, etc.) has been cut off. This means you should make sure that the RS-485 is disconnected from the instrument or that Supervision system acquisitions have been stopped.

6.2.2. UNICARD

The Unicard lets you download/upload a parameter map from/to a controller, in the same way as the CopyCard. It is a versatile tool that also allows you to quickly and easily customise devices. It differs from the Copy Card in the following ways:

1) it can be connected to a computer via USB

2) it can be plugged into a USB socket or USB battery, to power the device directly during upload/download.

The UNICARD can be powered in the following ways:

6.3. BOOT LOADER FIRMWARE

The device is equipped with a Boot Loader, so it is possible to update the Firmware directly on site. Updating may be carried out using UNICARD or CopyCard (CopyCard).

Updating procedure:

• Connect the UNICARD/CopyCard equipped with the application;

• Power the device if it is off, otherwise switch it off and on again

NOTE: the UNICARD/CopyCard can be connected even with the instrument powered.

• Wait until the LED for the UNICARD/CopyCard is blinking (operation in progress);

• The operation will be concluded when the LED for the UNICARD/CopyCard is:

• ON: operation concluded correctly;

• OFF: operation not performed (application not compatible...)

NOTE: the LED display is only provided for UNICARDS produced from week 18-12 onwards.

6.4. COMPRESSOR

SEt

The compressor is controlled by the device’s relay. It will be switched on or off depending on:

• the temperature status readings from the cold room probe

• the temperature control functions set

• the defrost/dripping functions (see Defrost chapter)

6.4.1. Compressor configuration

See the wiring diagrams for details of how to connect the compressor to the device Relay polarity is fixed.

NOTE: you MUST check the Compressor  digital output (relay) association by setting parameter H2x accordingly. NOTE: By default H21 = 1 (compressor)

6.4.2. Second compressor configuration

Coldface offers the option of using a second compressor NOTE: you MUST check the Compressor 2  digital output (relay) association by setting parameter H2x accordingly. Example H25 = 10 (compressor 2).

NOTE: to prevent the two compressors from starting up with an insufficient interval in between, an activation delay can be set for the second compressor using dSC.

6.4.3. Compressor operating conditions

Compressor operation The regulator is active when:

• the device is ON

• there is not an alarm E1 indicating control probe fault

• the time set in parameter OdO has elapsed

• a defrost cycle is not underway (except in FREE mode) (There is a fixed interval of one second between the request and activation of the relay)

The parameters that control this regulator are:

• the setpoint that can be set via the keypad, with a range from minimum to maximum setpoint.

• the differential

6.5. COMPRESSOR/GENERAL PROTECTIONS

Description

If the cold room probe is in error E1 the output relay configured as compressor/general regulates in accordance with the times set in parameters Ont and OFt.

The first time to consider is Ont. If Ont >0 the protection programmed in parameters

dOn-dOF-dbi (see safety compressor times).

NOTE: remember that parameter OdO inhibits the activation of all outputs commanding a relay for its entire duration

(compressor/general, defrost, fans), excluding buzzers or alarm relays.

Operating conditions

The table below lists the ways the compressor relay output can be managed:

Ont OFt Compressor OUT

0 0 OFF

0 >0 OFF

>0 0 ON

>0 >0 Duty-cycle

If Ont > 0 and OFt = 0 the compressor regulator entrusts relay deactivation to the safety protection CAt. If Ont > 0 and OFt > 0: the compressor regulator activates in operating cycle mode irrespective of the values read

by the probes (cold room probe failure) and of requests from other loads (Duty-cycle mode). If the cold room probe is working properly, Duty-cycle mode does NOT activate as it does not have priority over normal

compressor regulator settings.

The following diagram shows the Duty-cycle operating mode, based on parameters Ont and OFt > 0:

6.5.1. Compressor safety timings

OUT

Compressor on-off operations must respect the safety times that you can set using the special parameters as described below. The compressor icon will flash to indicate when a compressor activation request has been received but a safety protection exists. A safety time (compressor On... Off safety time) regulated by the parameter dOF must be respected between a switch-off and switch-on of the same compressor. This waiting time also occurs at switch-on of the device. A safety time regulated by the parameter dbimust be respected between one switch-on and the next. The safety time set in parameter dOn must elapse between a compressor start-up request and actual start-up. Times set with parameters dOn, dOF and dbi, if active, are not accumulative but parallel. The following diagram illustrates the operation of the compressor protection with parameters dOn, dOF, dbi set where:

6.6. DEFROST/DRIPPING

6.6.1. Defrost type and activation

Defrost is used to stop ice from forming on the surface of the evaporator. Its activation can be:

• automatic, in one of the following modes selected via dCt:

• compressor hours (Digifrost);

• device hours;

• compressor stop;

• via clock (see corresponding paragraph under RTC);

• via digital input (DI);

• via key;

• remotely.

The type of defrost can be selected via the parameter dtY and can be:

1. defrost with electric heaters;

2. inverse;

3. FREE

Dripping

On completion of defrost, given that there will be water on the evaporator, it is better not to start “cooling” right away as this would ruin the effect of the defrost by creating ice immediately. The dripping interval is regulated via parameter dt.

Defrost conditions and operation

Defrosting is enabled if:

• the evaporator temperature, read by probe 2, is lower than the defrost end setpoint configured via parameter dSt

• manual defrosting has not already been activated, in which case the request for automatic defrost will be cancelled.

Defrost requests can be made in the following ways:

Controller power-on if parameter dPO (defrost at power-on) is programmed accordingly.

Time intervals if dit > 0 whenever the defrost time interval set in parameter dit elapses.

Manually (via key)

External request via digital input (DI)

HACCP models also offer the following mode:

Time

by pressing the UP key The cycle will not start if OdO≠0; the request will be refused and the display will flash three times to indicate that defrost is impossible.

If the digital input (DI) is suitably configured. Activation via digital input (DI) respects the protections of the automatic cycle. The cycle will not start if OdO≠0; the request will be refused and the display will flash three times to indicate that defrost is impossible.

if dit = 0 and dCt=3 with rtc function (real time clock). At the times set in parameters dE1...dE8 (dd folder)

9MA10258.01 07/2018

Page 47

6.6.2. Automatic defrosting

The defrost cycle is programmed to start at intervals.

NOTE: To disable the automatic cycle, set dit=0.

If dit>0, the defrost cycles will be run at fixed intervals, as indicated in parameter dit and the interval time is counted as follows:

Par. Value U.M. Description Notes

In this case, the counter runs only if the compressor is on.

dCt

0 num

1 num

Hours of compressor compressor (DIGIFROST method®)

Device running time

A new count starts when the defrost interval elapses and a new defrost cycle starts if conditions permit. NOTE: compressor running time is counted separately from the evaporator temperature. If the evaporator probe is missing or faulty, the count continues for the time the compressor is on.

The defrosting interval is counted continuously when the device is on and starts at each power-on. A defrost cycle starts when the defrosting interval elapses (indicated by dit) if conditions permit and the controller immediately starts counting a new defrosting interval.

2 num Compressor stop

3 num

NOTE: regardless of how the interval is counted, the following conditions apply:

If parameter OdO is underway or the temperature read by the evaporator probe is higher than dSt, then defrost will not be permitted: a new interval will be counted and only at the end of this subsequent count will conditions be tested for the start of a defrost cycle.

RTC (clock)

Each time the compressor stops, a defrost cycle is run according to the mode set in parameter dty.

The clock can be used to set:

• defrost times (6 bands for weekdays and 6 bands for weekends/holidays),

• regular defrosts (every n days)

• daily events (1 event for weekdays and 1 event for weekends/holidays)

Time band defrosts and periodic defrost are mutually exclusive functions (they cannot be activated simultaneously).

If defrost by RTC has been enabled and the clock has failed, the defrost will run according to the mode set in dit (provided the value is ≠ 0).

6.6.3. Manual defrost

Press and hold the manual defrost key ESC (or from digital input (DI) if appropriately configured H11...H13 = 1), the device enters defrost. Procedures for the activation of this defrost cycle are the same as for external defrost.

The defrosting interval will now be counted as described for Automatic Defrost (time dEt is not cleared, it continues).

If the conditions for defrost activation are not present, i.e.:

• the time set in parameter OdO has not elapsed

• the evaporator temperature is higher than the value set in parameter dSt

this will be indicated on the display (screen flashes three times) and the defrost will stop.

Manual defrost is always enabled except when dit = 0.

6.6.5. Defrost WITH REMOTE START/STOP

If the Digital Input is configured for this function (if H11...H13 = ±22) defrost with start/stop is activated from remote. The defrost is switched on when the digital input becomes active. Vice versa, when the digital input is disabled, the defrost ends.

If the automatic defrost is also active, the two functions will proceed in parallel. In this case, the defrost interval set in the parameter dit will be reset when the remote defrost is activated (digital input). Having ended the remote defrost, the dripping function will be activated if dt > 0.

The conditions for activation are:

• Defrost probe present and temperature lower than dSt;

• Defrost not inhibited by an alarm.

The defrost will not be activated if the following conditions are present:

1. Defrost end probe present and temperature higher than dSt;

2. Alarm condition inhibiting the defrost,

The defrost may end before the defrost is disabled from the digital input (DI) if:

• dEt ends the count;

• Defrost probe present and temperature higher than dSt;

• Alarm condition ending the defrost early.

To manage the activation delays of the digital inputs DI1 and DI2 separately:

• Set dAd = 0;

• Add a delay using parameters O1i (to delay the activation of digital input DI1) and O2i (to delay the activation of digital input DI2), the delay of the digital input DI3 can be set using parameter di3.

NOTE: If dAd ≠ 0, any delays set in O1i and O2i will not be considered by the instrument.

6.7. DEFROST MODE

6.7.1. Defrost with electric heaters

Defrost with electric heaters is configured via parameter dtY = 0.

The compressor remains stopped for the duration of the defrost cycle and the relay configured as defrost regulator output, to which the electric heaters are connected, activates. On completion of defrost, the electric heaters are switched off and the compressor remains off for the dripping time set in parameter dt, if it is not equal to zero.

Defrost ends due to:

NOTES:

• If dSt intervenes before dEt, dripping (dt and Fdt) aligns with dSt.

• If Fdt < dt then Fdt = dt.

• During defrost, fans are OFF if parameter dFd is set accordingly, otherwise they will behave as set for the fan regulator.

Due to timeout set in parameter dEt (defrost timeout)

Temperature setpoint for the end of defrost set in parameter dSt reached. If this setpoint is not reached within the time set in parameter dEt (defrost timeout), the defrost will end due to timeout.

Defrost Output

Hot gas defrost is configured by setting parameter dtY = 1.

The compressor stays on for the entire duration of the defrost cycle and the relay configured as defrost regulator output, and that the solenoid valve is connected to, activates. On completion of the defrost cycle, the valve relay is de-energised and the dripping phase set in parameter dt (if not equal to zero) is interrupted. The compressor relay is once again controlled by the compressor regulator.

6.7.3. Double evaporator defrost

The defrost for a second evaporator can be controlled via the probe configured as second evaporator.

Configure a relay output (see configuration parameters H21…H25) as a defrost relay for evaporator 2.

To enable this function, you need to:

• set probe Pb3 to control defrost evaporator 2 mode (parameter H43).

• configure a relay output (see configuration parameters H21…H25) as a defrost relay for evaporator 2.

• Define defrost mode by setting parameter H45.

Input mode

A double evaporator defrost can take place in three different ways on the basis of parameter H45, as described below:

• H45=0: Defrost is enabled only when the temperature of evaporator 1 is lower than the value set in parameter dSt.

• H45=1: Defrost is enabled when the readings from at least one of the two probes is below its defrosting end temperature (dSt for evaporator 1 and dS2 for evaporator 2)

• H45=2: Defrost is enabled when both probe values are below the corresponding end of defrost setpoints (dSt for evaporator 1 and dS2 for evaporator 2)

The probe error condition is considered as a probe calling for defrost.

The defrost for every single evaporator ends when the following conditions have been met:

• the dEt/dE2 timeout period has elapsed

• the dSt/dS2 temperature has been reached

Ending mode

Defrost in the case of a double evaporator takes place when both probe values have reached or exceeded the relative end of defrost setpoints (dSt for evaporator 1 and dS2 for evaporator 2)

If one or both probes are in error, the end of defrost will take place due to timeout.

In any case

If there are no conditions for performing the defrost the request will be cancelled.

The defrost for a single evaporator will end when the corresponding probe reaches or exceeds the defrosting end temperature or when the timeout period begins.

Dripping begins when both defrosts have ended.

If one or both probes are in error, the defrost for the corresponding evaporator will end due to timeout. Onset is allowed as if the corresponding temperature is lower than the corresponding setpoint (dSt or dS2).

If the probe is not configured to be the probe for the second evaporator (H43 ≠2), the defrost for the second evaporator may take place if a digital output is configured to control defrost on the second evaporator (H21..H25 = 9). In this case consent for defrost will be

granted, as if the probe temperature (evaporator 2) < dS2 and the output takes place due to timeout. The fan regulator is not affected.

6.8.1. Evaporator fan operating conditions

The regulator is active when:

• the time set in parameter OdO has elapsed.

• the temperature of the evaporator probe, if present, is between the values of parameters Fot and FSt

• during defrost it is not excluded by the parameter dFd (dFd = y).

• dripping is not active (dt).

• the fan delay is not active after defrost (Fdt).

The request to switch fans on or off can be made in the following ways:

• by the compressor regulator to help in the “cooling” process (temperature control mode.)

• by the defrost regulator to check and/or limit the diffusion of hot air.

6.8.2. Fan operation in temperature control mode

During “cooling”, the fans operate as shown in this diagram:

Thermostat control of fans takes place at the values set in parameters

• FSt (fan disabling temperature) and FAd (fan differential).

• Fot (fan start temperature) and FAd but with the sign inverted.

By default, the fan disabling temperature, set by parameters FSt (fan disabling temperature) and FAd (fan differential), is an absolute value, as FPt = 0 (actual temperature value).

Depending on the parameter FPt, the fan disabling temperature set at parameter FSt can be absolute (actual temperature value) or relative (value to add to the Setpoint SEt).

Depending on the parameter FPt, the fan start temperature set at parameter Fot can be absolute (actual temperature value) or relative (value to add to the Setpoint SEt).

NOTE: if as an absolute value the parameter Fot is greater than FSt the fans will be excluded

Around the fan start temperature (-50°C by default) the differential will always take account of the differential parameter FAd but with the sign inverted (negative side). Fan stop in Fot, and activation at value (Fot + FAd).

The fan regulator operates as indicated below:

6.8.4. Fan operation in defrost

During defrost, the fans operate as shown in this diagram

dFd = n: the fans are not excluded during defrost

(see parameters FCO, Fon, FoF)

TEMPERATURE CONTROL / DUTY-CYCLE

dFd = y: exclusion of fans during defrost OFF

Thermostat control of fans takes place at the values set in parameters:

• FSt (fan disabling temperature) and FAd (fan differential).

NOTE: during defrost with electric heaters, the compressor is OFF but the fans work as if the compressor was still ON, unless they have been disabled during defrost (see parameter dFd).

When the evaporator fans are enabled in defrost (dFd = n) and regulate the evaporator probe Pb2 in thermostat controlled mode, when the latter enters error “E2” during defrost, the fans must always be ON, regardless of the values set via the Duty-cycle.

Fan operation without probe

If parameter H42 = n (probe Pb2 absent), depending on the FCO value and the status of the compressor, the fans may assume the status “On”, “Off”, “Duty-cycle”.

The parameter FCO will determine the operating mode of the evaporator fans during the DAY phase and the NIGHT phase.

The following is an example of fan operation on the basis of the value set for FCO.

6.8.5. Fan function during dripping

If parameter dt ≠ 0 (dripping time), the fans will stay OFF for the time set in this parameter. See “Defrost with electric heaters”. Note that if Fdt (fan delay time) is greater than dt (dripping time) the fans stay OFF for the time set in Fdt rather than dt (e.g. whichever timing is longer will be applied).

6.8.6. Post-ventilation

Parameter FdC delays the switching off of the fans after the compressor has stopped (increasing efficiency of the system by making better use of inertia). Post-ventilation must be active with any FCO value and without a configured probe. If FdC = 0 the function is disabled.

NOTE: Post-ventilation does not have priority over the delay set by parameter dcd.

6.9. DEEP COOLING CYCLE - DCC

DI1, DI2, UP

Description

This regulator ensures that the compressor regulates the setpoint dCS, with differential equal to the value set via parameter diF. When the DCC (Deep Cooling Cycle) activates, the interval between defrost cycles is cleared and defrosts are disabled.

Ending of the DCC is time-based, by setting the parameter tdc≠0, or when the setpoint dCS if tdc = 0.

When a DCC has ended and once the time set in parameter dcc has elapsed, a defrost cycle is forced and the counters restart for the interval between defrost cycles (value set via parameter dit). If dcc=0 defrost begins at the end of the DCC. During the DCC the temperature alarms are disabled. Normal temperature alarm management is restored at the end of the DCC, when the temperature value read by probe Pb1 reaches the regulation setpoint value SEt.

Operating conditions

The Deep Cooling Cycle will be activated via Digital Input or via a suitably configured key.

In the event of a probe error and/or power failure, the Deep Cooling Cycle is stopped and standard controller function restored.

If the dCS parameters are changed, tdc and dcc the functioning of the Deep Cooling Cycle is recalculated with new set values.

NOTE: After a Deep Cooling Cycle, the dcc time must elapse before a new cycle can begin.

6.10. PREHEAT

The preheating phase is linked to a suitably configured digital input (H11... H13 = ±12).

In the period when the preheat output is active:

• the compressor output will be forced OFF;

• the compressor icon will flash.

The Preheat only affects defrosting in applications that require the use of the compressor (dty= 1 and dty= 2).

9MA10258.01 07/2018

Page 60

6.11. PRESSURE SWITCH

This regulator performs diagnostic procedures on an activated digital input by assigning the value ±11 (General pressure switch), ±09 (Minimum pressure switch) or ±10 (Maximum pressure switch) to one of the parameters H11...H13.

If a pressure switch input is activated, power to the compressor loads is immediately cut off, the corresponding alarm icon lights up to provide a visual warning and the alarms folder ALr is also displayed. The folder contains labels with the number of pressure switch activations (up to the maximum value set in parameter PEn):

• P01, P02, ...P0n... for general pressure switch

• H01, H02, ...H0n... for maximum pressure switch

• L01, L02, ...L0n... for minimum pressure switch

If the number of activations exceeds the maximum number defined by parameter PEn within a time less than the value of PEi, the following conditions occur:

• The compressor, fan and defrost outputs are disabled

• in the alarms folder ALr label PA , LPA or HPA are displayed (general, minimum or maximum pressure switch respectively).

• The alarm relay comes on (if configured).

NOTE: 1) if the number of activations exceeds the number set in PEn in the PEI time, the alarm is automatically reset.

2) the input must be:

• closed on itself if unused and the input is active when normally closed;

• open if unused and active when normally open;

• deactivated via digital input configuration parameter.

NOTES: 1) Once it has entered alarm status, the device must be switched off and on again, or reset using the rPA key in

the functions menu.

2) If parameter PEn = 0, the function is disabled and alarms and counters are also disabled.

3) The pressure switch alarm is not stored in EEPROM

4) During the pressure switch activation period the defrost interval count runs as normal.

Operating conditions

The number of pressure switch errors is counted using a FIFO method. The time interval PEi is divided into 32 parts; the counter is incremented by one unit if there are one or more activations during one part of the entire interval PEi. Two operating examples are given below: In both cases, suppose that PEi = 32’ (equal to 32’/32 = 1 minute) and PEn = 7.

Example 1: ALARM SIGNALLED. The interval for storing activations is 1 minute: all activations within that minute

are counted as a single activation and the alarm is activated when the sampling interval has elapsed. In this example the pressure switch alarm is signalled because there have been 7 activations during the 32’ time window.

Example 2: ALARM NOT SIGNALLED In this example the alarm is not activated because during the 32’ time window

the number of activations set in parameter PEn was not reached. In practice the time window is a rolling window and all activations that are outside of it are deleted: the reference point is the last activation and the time PEi is subtracted from that point to establish how many activations are included in the count.

6.11.1. AUXILIARY OUTPUT (AUX/LIGHT)

Description

If one of the parameters H21...H25 is set to the value H2x=5, it anticipates the relay control as AUX and, by pressing the associated key H32...H35 which must be set to the value H3x=2, the relay is activated if it was off previously and vice-versa.

The on/off status is saved in non-volatile memory hence when power returns after a blackout, the device will restart in the status that was active prior to the blackout.

If one of the parameters H11...H13 is set to the valueH11...H13=±3, it anticipates the AUX relay control by the digital input; in this case the relay will mirror the status of the input. In this case, on/off status is not saved in non-volatile memory.

NOTE: the meaning of the digital input (DI) must always remain the same: for example, if the relay is activated by digital input (DI) and switched off by key, when the digital input (DI) is reset to the starting position, the relay does not change status (since it was already de-energised by key). With the instrument OFF, if set accordingly, only the digital input (DI) and the associated key can change the status of the output.

Operating conditions

The regulator is activated by:

• Key

• Function

• Digital Input

if configured accordingly.

The regulator is not active when:

6.12. DOOR/EXTERNAL ALARM MANAGEMENT

The door switch input is associated to an appropriately configured digital input (H1x = ±4). By controlling the opening of the door, it is possible to disable the compressor output and/or the fans.

It is also possible to associate a deactivation delay with the compressor output by means of parameter dCO. If the door is opened during a defrost cycle, the cycle is not shut down.

The values that can be set for the parameters involved are:

dod: Door switch switches off loads on digital input (DI) command

• 0 = function disabled

• 1 = disables fans (FAN)

• 2 = disables the compressor (COMP)

• 3 = disables the compressor (COMP) and fans (FAN)

Any protective timers (e.g. compressor start delay, etc.) will still be observed.

rLO: Locks compressor, defrost and fan regulators if the digital input (configured as external alarm) is activated.

• 0 = no resource locked

• 1 = Compressor and Defrost locked

• 2 = compressor, defrost and fans locked

dOA: Establishes what should be enabled/disabled on enabling/disabling of the Digital input. Only applies if PEA ≠ 0.

• 0 = activates the compressor (COMP)

• 1 = activates fans (FAN)

• 2 = activates the compressor (COMP) and fans (FAN)

• 3 = deactivates the compressor (COMP)

• 4 = deactivates fans (FAN)

• 5 = deactivates the compressor (COMP) and fans (FAN)

PEA: Establishes which of the door switch and alarm should be linked to the parameter dOA in the following way:

• 0 = function deactivated

• 1 = function linked to door switch

• 2 = function linked to external alarm

• 3 = function linked to door switch and external alarm

dCO: Compressor resource activation/power off delay (0 ...255 min).

dFO: Evaporator fan resource activation/power off delay (0 ...255 min).

tdO: Door open alarm exclusion time (0...255 min). The door open alarm will be activated if the door remains open for a time

period greater than the setting for this parameter.

The way in which parameters dCO and dFO act depends on how parameter dOA is configured. To better understand the meaning of these parameters, refer to the figures below.

The graphs below illustrate fan operation on the basis of the dOA value. In the graphs, we can see that:

6.13. DEMISTING HEATERS (FRAME HEATERS)

FRAME HEA

The controller is equipped with a regulator for the demisting heaters.

Operating conditions

The table below lists the ways the relay output can be managed:

HOn HOF FRAME HEATER OUT

0 0 OFF

0 >0 OFF

>0 0 ON

>0 >0 Duty-cycle

Where HOn = 0 the regulator is always off, while if HOn > 0 and HOF = 0 the regulator is always on. If HOn > 0 and HOF > 0: the regulator activates in operating cycle mode irrespective of the values read by the

probes (cold room probe failure) and of requests from other loads (Duty-cycle mode). If the cold room probe is working properly, the Duty-cycle mode does NOT activate as it does not have priority

over normal regulator settings.

The following diagram shows the Duty-cycle operating mode based on the parameters HOn and HOF > 0:

6.14. CONDENSER FANS

This regulator is associated with probe Pb3 (see specific section) and features:

• intervention setpoint SCF

• operating differential dCF

• exclusion of fans during defrost dCd

• activation delay after end of defrost tCF

If a digital output is set as condenser fans (H21...H25=12), this output will behave as follows:

SCF-dCF

OFF

dCF

If probe Pb3 is not present and if alarm E3 is active, the regulator will always be active except during the defrost cycle. Probe 3 can be excluded and, in this case, its lack of connection to the instrument will not cause any error signalling to occur.

NOTE: During the dripping time the output is OFF. NOTE: If a digital output is programmed as “condenser fans” (H21...H25=12), parameter SA3 is always an absolute value,

regardless of the value assumed by the parameter Att.

6.15. STAND-BY

Operating conditions

The stand-by regulator can be activated by digital input (if configured) or by key (if programmed).

With the device OFF the display shows “OFF” and all regulators are blocked including alarms.

When the device is switched on via a key or an appropriately configured digital input, regular operation commences, the same as from power-on. After power-on, the temperature alarm is excluded for a time set in parameter PAO, and the delay set by parameter OdO is activated. Each time that the device is switched off, all cycle times are reset. The on/off status is saved in non-volatile memory hence when power returns after a blackout, the device will restart in the status that was active prior to the blackout. The output from stand-by is linked to the delay set in parameter OdO.

NOTE: With the controller off, all relays are de-energized except for Aux: button/aux input-light-door switch are active.

User parameters

The parameters that manage the stand-by regulator are:

Label Description

PAO Alarm disabling after power-on

OdO Output activation delay from power-on

OAO High/low temperature alarm exclusion time after door closing

6.16. PUMP DOWN

In some applications, Coldface manages the fluid solenoid valve, located in the cold room, while the refrigeration output is generated by a condenser unit, where the compressor is switched on/off directly by a minimum pressure switch on the unit itself. Pump-down mode can be used to manage the compressor directly by connecting the minimum pressure switch to the Coldface, which means it can also be used for diagnostics. The purpose of this regulator is to allow compressor activation (pump-down compressor output) exclusively on the basis of minimum pressure switch regulation and regardless of the status of the main temperature controller, which will be used to enable/disable solenoid valves (compressor output) instead.

6.16.1. Service stoppage

Service stoppage switches the cold room OFF, and this status is indicated on the display. It also allows compressor activation every time the pressure on the suction line rises until the minimum pressure switch starts running (pump-down).

8.3. DESCRIPTION OF ALARMS

8.3.1. PROBE alarm

OPERATING CONDITIONS

When one of the probes is out of the nominal operating range or in the case of an open probe or a probe in short circuit, an alarm is generated if this condition persists for longer than 10 seconds. The alarm condition is indicated on the display by means of the following error codes:

• E1 = Pb1 probe error

• E2 = Pb2 probe error

• E3 = Pb3 probe error

The alarm icon and alarm relay are activated. Codes E1, E2, E3, when occurring at the same time,are shown in the following sequence: E1 x 2 seconds, E2 x 2 seconds, E3 x 2 seconds, etc.

ACTIONS ON CURRENT REGULATION

For all probes, the probe error condition causes the following actions:

• the display shows code Ex (where x = 1, 2, 3)

• activation and permanent display of alarm icon and activation of alarm relay (if present)

When the faulty probe condition ceases, regulation resumes as normal. During the probe error, the defrost interval count continues as normal.

SIGNALLING

Code Meaning

E1 Probe Pb1 error E2 Probe Pb2 error E3 Probe Pb3 error

ALARM ACKNOWLEDGEMENT

In the alarm condition, it is possible to acknowledge the alarm and/or relay configured as an alarm, even if the alarm condition persists, by pressing any key or using the corresponding function in the menu. The alarm icon will start to blink. Eliminating the cause of the alarm disarms the acknowledgement. The probe alarm error is not stored by the controller.

8.3.2. MINIMUM AND MAXIMUM TEMPERATURE alarm

SEt + HA1/3 – AFd

OPERATING CONDITIONS

The alarm regulation is carried out on probe 1. The temperature limits defined in parameters HAL and LAL are determined by parameter Att which specifies if they represent the absolute temperature value or a setpoint differential (in the case of offset on the entered setpoint, the high and low alarms will refer to this new control set point).

• If Att=0 Ab(solute) , the temperature limits for probe 1/3 are absolute.

• If Att=1 rE(lative) , the temperature limits for probe 1/3 refer to the Setpoint SEt

NOTE: to obtain the minimum alarm below the setpoint in the case of Att=1 (relative) set LAL < 0

ALARM CONDITIONS

A maximum/minimum alarm is generated when the Pb1 temperature is:

• Maximum alarm: ≥ HAL if Att=Ab(solute) and ≥ (SEt + HAL) if Att=rE(lative)

• Minimum alarm: ≤ LAL if Att=Ab(solute) and ≤ (SEt + LAL) if Att=rE(lative)

IfAtt=Ab(solute) the values of HAL and LAL must be with sign, if Att=rE(lative) it is necessary that HAL > 0 and LAL < 0.

When one of the two aforementioned conditions occurs, if no alarm override times apply (see alarm override parameters), the alarm icon lights up and the relay configured as alarm activates (if present).

The maximum/minimum alarm will be reset when the temperature of probe 1/2 is:

• Reset from maximum alarm: ≤ (HAL - AFd) if Att=Ab(solute) and ≤ (SEt + HAL - AFd) if Att=rE(lative)

• Reset from minimum alarm: ≥ (LAL + AFd) if Att=Ab(solute) and ≥ (SEt + LAL + AFd) if Att=rE(lative)

8.3.3. END OF DEFROST DUE TO TIMEOUT alarm

OPERATING CONDITIONS

The regulator is activated without any delay in the case of end of defrost due to timeout, instead of probe 2 reaching the defrost end temperature. The action consists of:

• alarm icon steadily on

• recording of Label Ad2 in the alarms menu. Automatic reset occurs with the start of the next defrost cycle. The alarm icon can be switched off using the normal acknowledgement procedure, although the alarm signal is only actually cancelled at the start of the next defrost cycle.

8.3.4. EXTERNAL alarm

OPERATING CONDITIONS

In the case of activation of the digital input, the alarm regulator is activated with the delay set by parameter dAd, and this alarm persists until the next time the digital input is deactivated. The action consists of:

• alarm icon steadily on

• recording of Label EAL in the alarms menu.

• Activation of the relay configured as alarm (if enabled)

• deactivation of regulation if parameter rLO requires it.

It is possible to mute the alarm relay but the regulators still remain locked until the next time the digital input is deactivated.

The values that rLO can be assigned to parameter:

• rLO = 0: an external alarm has not locked any resource;

• rLO = 1: an external alarm has locked the compressor and defrost;

• rLO = 2: an external alarm has locked the compressor, defrost and the fans.

8.3.5. DOOR OPEN alarm

OPERATING CONDITIONS

The door switch alarm is associated to a specially configured digital input:

• H11, H12, H13 = ± 4

On activation of the digital input (door open) and after delay tdO has elapsed, the door open alarm must be signalled in the alarms folder and the icon and alarm relay should come on. The label OPd is displayed. The action consists of:

• alarm icon steadily on

• recording of Label OPd in the alarms menu.

• Activation of the relay configured as alarm

As in the case of the other alarms, the relay may be disabled by pressing an acknowledgement key, the alarm icon will blink and label OPd will remain in the alarms menu until the door is closed. If the door is opened, the regulator will operate on the basis of the value of parameter dOd. The values that can be assigned to it are:

• dOd = 0: no resource is locked;

• dOd = 1: fans are locked (FAN);

• dOd = 2: the compressor is locked (COMPR);

• dOd = 3: both the fans (FAN) and compressor (COMPR) are locked

If the door open alarm locks the compressor, it can still be reactivated even if the door remains open, by setting the parameter dCO.

8.3.6. PRESSURE SWITCH INPUT alarm

OPERATING CONDITIONS

The pressure switch is associated with a suitably configured Digital Input and can be general, minimum or maximum.

NOTE: behaviour and configuration parameters are the same for all three types.

Every time pressure switch input activation causes the compressor/fans to be disabled instantly, with only visual indication of the activation (WARNING) provided via illumination of the alarm icon and recording of the number of pressure switch activations that have taken place.

If the pressure switch Digital Input is deactivated, the compressor starts up again and the alarm icon switches off, but the alarm folder still contains the number of activations recorded in the previous counting interval (defined using parameter PEi). Once the number of activations set in parameter PEn has been reached PA (general), LPA (minimum) or HPA (maximum) will appear on the display.

Compressor, fans and defrosts are deactivated, the alarm icon lights up and the alarm relay comes on if configured. Once the device has entered alarm mode, it must be switched off and on again, or a key-activated reset performed using the function rPA (reset pressure switch alarm) on the functions menu.

NOTA: PEn represents the number of pressure switch activations within the interval defined in parameter PEI, which determines activation of alarm mode and deactivation of the compressor, fan and defrost outputs If PEn = 0 the function is excluded and the pressure switch alarm is ignored.

• H11, H12, H13 = ± 21 This alarm is activated after the delay set in parameter di3 and it persists until the next digital input deactivation. The action consists of:

• Panic alarm icon blinking

• Alarm icon steadily on

• intermittent sounding of alarm buzzer

• recording of Label “ALd” in the alarms menu

• activation of the relay configured as alarm (if enabled)

The alarm relay can be inhibited by pressing any key; this action mutes the buzzer while the icons respond as follows:

• alarm icon blinking

• Panic alarm icon steadily on

If the “Leak Detector” alarm occurs in synchrony with the “Panic” alarm, the system response is as follows:

• Panic alarm icon steadily on

• Alarm icon steadily on

• intermittent sounding of buzzer

• recording of labels “Pan” and “ALd” in the alarms menu

9. MODBUS MSK 554 FUNCTIONS AND RESOURCES

ModBUS is a client/server protocol for communication between devices connected in a network. ModBUS devices communicate using a master-slave technique in which only one device (master) can send messages. The other devices in the network (slave) respond, returning the data requested by the master or executing the action contained in the message sent. A slave is a device connected to a network that processes information and sends the results to the master using the ModBUS protocol. The master device can send messages to individual slaves or to the entire network (broadcast) whilst slaves can only respond individually to the master. The ModBUS standard used by Eliwell employs the RTU code for data transmission.

9.3.1. DATA FORMAT (RTU)

The coding model used defines the structure of messages transmitted on the network and the way in which this information is deciphered. The type of coding is usually selected on the basis of specific parameters (baudRate, parity, etc.); furthermore, some devices support only specific coding models, although it must be the same one for all devices connected in a ModBUS network. The protocol uses the RTU binary method with bytes configured as follows: 8 bits for data (non-configurable), parity bit

none, 1 stop BIT.

Parameter setting allows the integral configuration of the device Changes can be made via:

• Device keypad

• Copy Card

• data via Modbus protocol directly to an individual controller or broadcasting it, using the address 0 (broadcast)

9.3.3. ModBUS COMMANDS AVAILBLE AND DATA AREAS

The following commands are implemented:

ModBUS command Command description

03 (hex 0x03) Read 16 consecutive registers for Client side.

04 (hex 0x04) Read 1 single register for parameters.

16 (hex 0x10) Write 15 consecutive registers for Client side

22 (hex 0x16) Write 1 register for the parameters

43 (hex 0x2B) Read device ID.

It is possible to read the following 3 fields:

Field code Field description

0 Manufacturer ID (=”Invensys”)

1 Device model/polycarbonate ID

PCH = 251 (FB hex) POLI = 1025 (0401 hex)

2 Device family (MSK554)/version ID

MSK = 554 (22A hex) REL = 0601 (259 hex)

format: 00FB_0401

format: 022A_0259

9.3.4. ADDRESS CONFIGURATION

The serial TTL - which we will call COM1 – can be used to configure the device, parameters, states, and variables with ModBUS via the ModBUS protocol.

The address of a device within a ModBUS message is set using the parameter Adr.

The address 0 is used for broadcast messages that all slaves recognise. Slaves don’t respond to broadcast messages. The parameters for configuring the device are:

Parameter Description Values Range

PtS Select COM1 (TTL) protocol d

Adr ModBUS protocol controller address 1 1...250

Pty ModBUS protocol parity bit n

bAU Baudrate selection. 96

NOTE: for correct operation, the controller must be switched off and switched on again after modification

t = Televis d = ModBUS

• n= NONE

• E = EVEN (parity)

• o = ODD (disparity)

• 96 = 9600 baud

• 192 = 19200 baud

• 384 = 38400 baud

9.3.5. PARAMETER VISIBILITY AND VALUES

NOTE:

1) When not indicated otherwise, the parameter is always visible and modifiable, unless customised settings have been configured by the user via serial

2) If folder visibility is modified, the new setting will apply to all parameters in the folder.

9.3.6. MODBUS TABLES

The tables below list all information required to read, write and decode all accessible resources in the device. There are 3 tables:

- the “PARAMETER TABLE”contains all device configuration parameters stored in the controller’s non-volatile memory,

- the “FOLDER VISIBILITY TABLE (FOLDER)” indicates the visibility of the folders containing the parameters

- the “CLIENT TABLE” includes all I/O and alarm status resources available in the volatile memory of the instrument.

Description of the columns:

FOLDER

Indicates the label of the folder containing the parameter in question

LABEL

Indicates the label used to display the parameters in the menu of the controller.

PAR. VALUE ADDRESS

The whole part represents the address of the ModBUS register containing the value of the resource to be read or written in the controller. The value after the decimal point indicates the position of the most significant data bit inside the register; if not indicated it is taken to be zero. This information is always provided when the register contains more than one information item, and it is necessary to distinguish which bits actually represent the data (the working size of the data indicated in the column DATA SIZE is also taken into consideration). Given that the ModBUS registers have the size of one WORD (16 bit), the index number after the point can vary from 0 (least significant bit -LSb-) to 15 (most significant bit -MSb-). Examples (in binary form the least significant bit is the first on the right):

including visibility

PAR. VALUE ADDRESS DATA SIZE Value Content of register

IMPORTANT: when the register contains more than one piece of data, the writing procedure is as follows:

• Read current value of register

• Modify bits for the resource concerned

• Write register

VIS PAR. ADDRESS

The same as above. In this case, the ModBUS register address contains the visibility value of the parameter. By default all parameters have:

• Data size 2 bit

• Range 0…3

• **Visibility 3

• U.M. num

**Value Meaning

• Value 3 = parameter or folder always visible

• Value 2 = installer level; these parameters can only be viewed by entering the manufacturer password (see parameter PS2) (all parameters specified as always visible, parameters visible at the installer level and manufacturer level will be visible)

• Value 1 = user level; these parameters can only be viewed by entering the installer password

(see parameter PS1) (all parameters specified as always visible and parameters visible at the installer level will be visible)

• Value 0 = parameter or folder NOT visible

1. Parameters and/or folders with a level of visibility =1,2 (password-protected) will be visible only if the correct

2. Parameters and/or folders with a level of visibility =3 are always visible even without a password: in this case, the

8806.7 4 BIT 10 1350 (0000010101000110)

password is entered (installer or user) following this procedure:

following procedure is not necessary.

49337.6 2 BIT 3 65535 (000000001111111111111111 )

R/W

Indicates the option of reading or writing the resource R The resource is read-only W The resource is write-only RW The resource can be both read and written

DESCRIPTION This is the description of the meaning of parameters in the LABEL column.

DATA SIZE

Indicates the size of the data in bits. WORD = 16 bit Byte = 8 bit “n” bit = 0...15 bit based on the value of “n”

CPL

When the field indicates “Y”, the value read by the register needs to be converted because the value represents a number with a sign. In the other cases the value is always positive or null. To carry out conversion, proceed as follows:

• if the value in the register is between 0 and 32,767, the result is the value itself (zero and positive values)

• if the value in the register is between 32,768 and 65,535, the result is the value of the register – 65,536 (negative values)

EXP WHEN UTILISING MODBUS PROTOCOL ONLY

If = -1 the value read by the register is divided by 10 (value/10) to convert it to the values indicated in the RANGE and DEFAULT columns using the unit of measure indicated in the column U.M.

Example: parameter HSE = 50.0. Column EXP = -1:

• The value read by the device /DeviceManager is 50.0

• The value read by the register is 500 --> 500/10 = 50.0

RANGE

Describes the interval of values that can be assigned to the parameter. It can be correlated with other parameters in the instrument (indicated with the parameter label).

U.M.

Unit of measure for values converted according to the rules indicated in the CPL and EXP columns.
