5. Electrical power supply cold room
A 4-pole socket outlet is located on the intake-side of the Refri­geration evaporator unit for the electrical power supply to the loads attached to the coldroom, with a total power capacity of max. 250 VA (lighting, door frame heating). The door contact switch can also be connected to this sokket outlet.
5.1 Connecting the door contact switch
The evaporator ventilator should be switched off when the cold storage cell is opened. For this reason, we recommend the installation of an potential-free door contact switch (swit­ching capacity 230VAC, min. 0.5 A). Connection takes place via the 4-pole socket outlet mounted on the intake-side of the evaporator unit. In its delivered condition, the unit is functionally ready for service without an external door contact switch. The door contact switch is not included within the scope of delivery of the unit. If a door contact switch is connected to the refrigeration unit, the regulation parameter must be changed (see also Point 9.3, Menu Settings). This is achieved through the following menu items:
Settings  Limiting values/Alarm Door contact Yes/No
Mains connection 230V AC via multi-pin connector
Door contact switch (optional)
5.2 Connection of the fault indicator contact
The electronic control unit is outfitted with a potentialfree Fault report contact for connection to the on-site Fault repor­ting equipment (max. 10A, 230VAC). The mains side electrical power outage is not monitored.
In the event of a fault, contacts IN and NO are closed.
The connection is located on the circuit board (plug connector X4).

5.3 Power supply connection and commissioning
Attention!
The electrical power supply should first be connected at commissioning - Risk of life!
Work on the power supply connector and protection devices must be carried out by a specialist company, in accordance with IEC 364, local regulations and the connection conditions of the respective energy supply company!
Insert the mains plug into a properly grounded outlet with personal protection measures (fault current circuit breaker) according to the specification plate.
GB
Electronic regulation
The equipment starts up after self testing the regulation. A warning signal sounds upon ramping up the regulation. Unless other selection is made during ramp-up, the regulation continues with the status which was set before discontinu­ation of the power supply. I. e. if regulation was in a cooling mode, it continues in the same mode. If it was in standby, it will remain in that mode.

6. Defrosting
6.1 Defrosting process
When the defrost function activates, the compressor and the fan are switched off and the heater for the defrost water hose is switched on.
Once the defrost water hose lead time has passed, the com­pressor switches on and the bypass valve opens. The heater for the defrost water hose continues running during this process. The compressor remains running until the set defrost tempera­ture is reached in the evaporator unit or the set maximum de­frost period has passed. The maximum defrost period should usually be set as a longer period rather than shorter one so that defrosting occurs in full. The correct position and thermal contact of the sensor in the evaporator unit must be checked during maintenance (see figure).
The sensor is inserted diagonally downwards from the left between the 9th and 10th fins and the 1st and 2nd sensor tube at a depth of 34 mm.
If the sensor is positioned against a tube that is close to the inflow during the defrosting process, defrosting does not complete fully. The sensor reaches the set defrost temperature prematurely and the control unit terminates the defrosting process. The ice is simply melted and sinks to the bottom. This results in a block of ice on the lower edge of the evaporator, which can only be manually defrosted by a service engineer.

Caution!
When using hot gas defrosting, the process should best be conducted quickly and often. Large ice formations cannot be melted as the defrosting process works with far lower temperatures and therefore less radiant heat.

6.2 Defrosting options
Defrosting cycle
The defrosting process is continually triggered at set intervals.
Defrosting plan
Defrosting is performed for well-defined periods. These can include 99 periods will be specified in a week time.
Manual defrosting
The cooling process is interrupted and a complete de­frosting process is conducted. The unit then re-activates the cooling mode.
6.3 Defrost water drain
The defrost water created is caught in the defrost water tray and largely evaporated by the evaporator loops. In the event of large volumes of defrost water or high humidity around the cell installation site, the use of the evaporator may not be sufficient. In such cases, an additional defrost water drain hose can also be attached to the evaporator tray. The accessories kit is optionally available and is compatible with all FS and CS series units.
- The air flow should not be directed at the doors and pressure compensation valves. Pressure compensation valves must always be installed in a position where they are barely influenced by the air flow.
- The goods introduced must be stored in sealed contai­ners. Goods with high water content are subjected to dehydration and thus damage. (Freezer burn on deep­frozen goods and shrivelling/drying out of fresh foods)
- Do not leave deep-frozen goods in the warm storage area on delivery. Defrost water will form on the surface and have to be cooled again. In the case of cardboard packaging, a great deal of moisture is absorbed in the surfaces and causes the evaporator to freeze over when the packaging is moved into the coldroom.
6.4 Preventing excessive defrost water
Defrost water is the melted ice formed by the evapora­tor. In other words, the ice was formed through a use of energy and likewise melted again. Due to the thermody­namically induced lack of humidity at the coldest point in the coldroom, ice formation cannot be prevented (vapour pressure drop) but can be minimised.
The following points should be noted:
- Units in deep-freezing rooms should always be coupled with a door contact switch that switches off the evapo­rator while the door is open.
- Doors should remain open for as little time as possible. If this is not possible, suitable measures must be taken to minimise the loss of cold. This can include several technical measures such as strip curtains, fast-sliding doors, air curtain systems, pre-cooling rooms etc.

7. Cooling mode
7.1 How the cooling mode works
After switching on the unit (Standby => No; see Point 8 ‘First steps’), the cooling mode activates. If the unit was only recently connected to the mains, the compressor standstill time (usually three minutes) passes. The com­pressor then switches on and starts the cooling process. The condenser fan switches on at an appropriate speed depending on the temperature at the condenser outlet. On reaching the ‘Start evaporator fan’ temperature or upon expiry of the ‘evaporator fan delay’, the evaporator fan switches on. Depending on the humidity setting, the fan runs at all times or when the compressor is switched on (see parameter list in Point 9.3). The compressor runs until the switch-off point is reached and re-activates when the temperature increases to the switch-on point. The points are determined by the desired coldroom temperature and the hysteresis (see parameter list in Point 9.3).
7.2 Description of the cooling mode types
Normal mode
The unit is started with ‘Standby = No’ then runs conti­nuously. The cooling mode is only briefly interrupted by the set defrost cycles.
Cooling schedule
The unit is started with ‘Standby = No’ then only runs at the times approved in the cooling schedule. The cooling mode is only briefly interrupted by the set defrost cycles. The cooling schedule must always be programmed for a week.

Description
After changing the language setting, the unit must be restarted.
Up to 8 di erent languages can be stored. The standard languages are German, English and French. In order to activate the changeover to another language, the language must be selected and then, the equipment disconnected from the power supply for a short time. Upon restarting, the new language is activated.
A name can be assigned for each refrigeration unit. In the case of bus operation, inputting the name for the assign­ment of rooms is helpful. In addition to the name, the unit number has to be input at the DIP switch, as well. Since up to 8 di erent refrigeration units can be controlled with one display, a logical structure of the name speci cations is de nitely required. (See Electrical circuit diagram, Page 66 to 69)
The evaporator fan runs together with the compressor. => Low relative humidity. The evaporator fan runs constantly. => High relative humidity.
Di erntial can be changed between switch-on and switch­o temperature. If the value is negative, the refrigeration unit switches o if the cold room temperature has reached the rated temperature value minus the absolute value of the di erntial. It turns on if the cold room temperature has reached the rated temperature again. Example: Rated temperature - 20°C Di erntial -2K Refrigeration unit O at -22°C Refrigeration unit On at -20°C If the value is positive, the unit turns o if the cold room temperature has reached the rated temperature value. It turns on if the cold room temperature has reached the rated temperature + di erntial. Example: Rated temperature +5°C Di erntial +2K Refrigeration unit O at +5°C Refrigeration unit On at +7°C
If the units are used in bus mode, a separate unit number must be set for each unit (see circuit diagram on pages 66-69)!
Redundancy = all units run with the same setting and tem­perature. Defrosting and cooling occur simultaneously on all units. Redundancy in this context means that if one unit fails, the second or remaining units continue to function. The units

Defrost cycle
Description
Wall-hanging unit: in the case of redundancy, all units in the bus system simultaneously begin defrosting.
Ceiling unit: units begin defrosting separately.
Restart required on selection.
Time interval for the data logger. In the case of 15 min recording interval, the ring bu er lasts for min. 2 years. The data can be read out to an USB stick as well as viewed and processed in Microsoft® Excel or OpenOffice™. In the graphic representation in the display, the time course is shown on a daily basis and can be selected in a targeted fashion within a speci c day.
Selection parameters for the defrost function Defrost cycle: At a predetermined interval of the defrosting operation is started. Defrost plan: By setting the shift points for the defrost de­frosting can be performed for well-defined periods. Defrosting must be programmed for a week. For 99 swit­ching points are available. When changing the defrost to restart the system is required.

Defrosting cycle: the defrosting process starts at a specified interval. Example: Every 2h defrosting cycle for a duration of 30 minutes => at 2:00 pm, defrosting is performed for 30 minutes, at 4:00 pm, defrosting is performed for 30 minutes, at 6:00 pm, defrosting is performed for 30 minutes. For limitation on defrosting, the defrosting limitation temperature is also applied. Thus, defrosting is performed for a maximum period of 30 minutes or until the defrosting limitation temperature is reached. It is better to defrost the units quickly and often than to have a long cycle period and a long defrosting process.
The defrosting limitation temperature is measured in the evaporator. For switching o , the defrosting duration (time in min) or the temperature is used. Whichever value is reached sooner. If no defrost termination probe is available, only the time is considered and the process is  nished after running the defrosting sequence.
Switchover between hot gas and fan-only defrosting. The temperature speci es up to which temperature the defrosting is only performed with the evaporator fan. Under this temperature, defrosting is performed by the use of hot gas or electric heating, respectively. Above this temperature, the ice layer on the evaporator is melted away for cooling of the room. For that purpose, the evaporator probe must not be fully frosted. Defrosting using the fan should ideally only occur for chiller rooms.

Description
After the defrosting process, a waiting time is applied until the normal operating mode (cool­ing) is returned. In the case of hot gas defrosting, the compres­sor downtime runs concurrently. I. e. the cooling operation can only start after elapsing of this time.
Lead time for the drain line. Starts prior to the start of the defrosting process. Thus, the defrosting water does not drip on the cold dripping tray and in the cold drain hose.
Displays the temperature before defrosting began in the data logger during defrosting and prevents temperature peaks during defrosting.

9.5.1 Mode of operation
All recordable faults are documented in the log book and stored in a continuously updated ring memory. Depending on the volume, the faults are stored for at least three months and then overwritten. The data can be exported and evaluated (*txt for­mat). The data in the memory cannot be deleted. For a better overview, the day on which a fault occurred is underlined in the date selection. Once this day has been selected, the temperature display or the event display can be accessed. The temperature data (optional) is also recorded. The ring memory can last for two years with a 15-minute recording interval. After two years, the oldest data records in the ring memory are overwritten. The logged data can be directly output onto the display or read via a data carrier. The data (* .txt format) can be imported into a spreadsheet and evaluated. The data in the memory cannot be deleted.
9.5.2 Licence release
If the data logger is retrospectively ordered, the display number must be reported to the factory. The display number can be found under Settings, Control panel, Licence. This display number is allocated to a release number in the factory, which is ente­red under the display number. Once the release number has been entered in the display, the temperature data is recorded.

10. Bus mode
10.1 Connection of the units and the display
The units are connected together using a CAT5E data cable and an RJ45 plug connector. The display must always be connected using the upper socket (see circuit diagram). A bus address must also always be allocated to each unit (binary code address on the controller board via DIP switch, see circuit diagram). If the units should be supplied with power via several electrical circuits, external potential equalization is required (min. 6 mm²). The potential di erence must not exceed 2 V. If this does not occur, the data connection can be destroyed and the cooling mode disrupted.
10.2 Bus operation modes
- Bus type: multi-cell
Up to eight coldrooms with di erent temperatures can be managed on a display. To better allocate the units to the rooms, the units can be given a name (see parameter list).
- Bus type: redundant
The units run jointly in a coldroom with the same para­meters. For FS and CS units, the model ‘wall-hanging unit’ must be selected (see parameter list). The model controls the defrost function so that all units are simultaneously defrosted. If the option ‘ceiling unit’ is selected, the units defrost at di erent times. For wall-hanging units, this would lead to ice formation.
10.3 Bus operation faults
In the event of outages within the network, the units always continue running with the last parameters to be transmitted from the display. When the connection is restored, the system automatically adjusts.

The mains connection is located on the circuit board in the housing. To connect the unit, the housing must be opened and connected using a suitable data cable.
The control unit can be connected via a mains cable. The connection occurs via a web browser and the appropriate IP address. Access is gained by entering the username ‘admin’ plus the applicable authorisation number (1234 for users and 90210 for service personnel). Internet access must be accordingly released. This occurs via the IT sup­port team at the installation site.

Connect the power plug and check the mains fuse. If you cannot determine a defect, contact an expert company. The supply voltage and frequency must always match the values speci ed on the type plate.
Check whether the voltage speci ed on the type plate is applied. Check whether the fuse protection is also ensured according to the ratings on the type plate. Ensure voltage supply.
Check wire connections of bus lines. The display connection must always remain plugged in to the upper socket! In the bus operation, the connection between the power boards is not speci­ ed.
Check whether the voltage speci ed on the type plate is applied. Check whether the fuse protection is also ensured according to the ratings on the type plate. Ensure voltage supply.
Check wiring of door contact switch. The n-conductor always switches! Short circuit occurs when mixed up! Unplug door contact connection (X2) and try again. If the fault is still present, unplug devices (connectors X3A to X3H) and try again. Work on electrical systems must only be conducted by quali ed electricians.
Brie y press the rotary knob. If still no display, check wire connections of the bus lines. The display connection must always be plugged into the upper socket of the power board! (see Electrical circuit diagram, Page 66 to 69) After the “Time Lighting” process (main menu “Settings”, sub-menu “Control Panel”), the display will go to sleep.
Up to 4 thermal detectors PT1000are built into the EVO-COOL®. The display will show which detector is defective (e.g. Log. detector not working correctly). To change a detector, please contact your refrigeration specialist. If the machine is not longer running, you may turn on the emergency opera­tion with the DIL switch on the main board. The machine will then continue running without temperature regulation and defrosting.
The refrigeration specialist company must be contacted immediately for maintenance!

refrigeration cycle regarding high pressure.
If the message ‘Package detector fault’ appears, a check must be conducted to see if the evaporator is covered in ice. Before replacing the detector, first remove the ice and check the detector’s position. The detector must not touch the evaporator’s tubes. If the detector touches the tubes, the defrost period is too short and the ice does not melt as the defrost temperature is reached prematurely.
The safety pressure switch (pressostat) has been activated. If the fault does not disappear following acknowledgement, please contact your refrigeration specialist. The safety circuit can contain not only the high pressure switch but also other components. (See the circuit diagram on pages 66 to 69). Unit runs continuously and the evaporator ices over.

The upper alarm limit for temperature monitoring was ex­ceeded by the delay time of the tempera­ture alarm.
The lower alarm limit was under-run by more than the set alarm delay time.
Due to in ow of warm moist air, a crust of ice is building up on the evaporator.
the door contact switch is open.
If the temperature continues to be above the alarm limit after acknowledg­ment of the fault, the delay time will start over. Check whether the doors are closed and the machine is cooling. You may read the current detector values under the menu item “Information”. If the package detector reads below room temperature, the machine is cooling. Check whether too many warm items were brought in for storage. Is the evaporator icy? Initiate manual defrosting and afterwards check if the evaporator is free of ice. Is the alarm limit to close to the hysteresis? Is the delay time set too short? Check, if the cold-water circulation (with devices with plate heat exchanger) is working correctly. Check if the air heat exchanger is supplied with enough cold air (air exchange).
Check the temperatures in the cool room. Was the temperature adjusted lately? Were large amounts of goods brought in that had a signi cantly lower tempe­rature?
Are the siphons  lled with water? Initiate manual defrosting and watch whether the evaporator is free of ice after the process is complete. If it is not,
- The defrosting cycle is too long and the defrosting time is set too short.
- The defrosting limitation temperature is set too low and prematurely turns o the defrosting process.
- Check whether the door closes correctly and is air-tight. Adjust if necessary.
- Check whether the pressure compensation valve is ok.
- Check whether the pressure compensation flap closes properly
- Check whether the filter fleece is correctly positioned
- Check whether the package detector is correctly positioned (not touching the evaporator tubes)
- Check whether moisture has infiltrated through the delivery of goods or per­sonnel movements
- Check whether the cell environment is extremely damp (vapour pressure) The door was opened for longer than released by the monitoring time. If this is
not the case: Is the door contact switch installed and activated by the door?
If the door contact switch is not installed, the position “Door Contact Switch” in the “Settings” menu / “Alarm Limit Values” must be set to “No”. In this menu you may also set the alarm time for the door.
Prevent leaving the doors open for long periods as this leads to ice formation on the evaporator and the cell.
