1 Unpacking the unit and conditions of use Before and when unpacking the unit, make a visual inspection to identify any possible damage which may have occurred during transportation. Please look for loose parts, dents, scratches, etc. Report any damage immediately to the freight company. (Please see “Conditions if damage has occurred”.) In other cases, the latest edition of the “General conditions for the supply of goods and services”...
Please take the application limits into account (see Technical Data, Chapter 12). 3.2 Function The PCR-310/-410 are microprocessor-controlled cold store controls for refrigeration and deepfreeze systems with a “snap-in” installation housing to fit in an aperture 28.5 x 70.5 mm and featuring: Compressor control (dependent upon cold store temperature) with delayed start-up.
4 Safety 4.1 Sources of danger Caution - Mains voltage! Never expose the unit or transformer to water or moisture. Risk of malfunction and short circuit. Only use the unit when it is adjusted to normal ambient temperature (+15 to +30 °C). Extreme changes in temperature in combination with high atmospheric humidity may lead to the formation of condensed water.
5 Installation and commissioning 5.1 Mechanical installation “Snap-in” housing: Fit the unit in an aperture 28.5 x 70.5 mm and secure it with the relevant mounting frame a) housings with terminal box cover plate (max. thickness 22 mm): b) housings without terminal box cover plate (max.
5.2 Electrical installation CAUTION: The mains voltage and system frequency must be the same as the nominal values on the device’s rating plate. Work on electrical systems must be performed by qualified personnel. Relevant local safety regulations must be observed. Wiring diagram;...
Selection of the emergency setpoint value for the cold store temperature: This will be activated if the data in the memory is lost and if alarm AL1 is activated. This sets all program parameters to the preset value. The cold store temperature setpoint can be preset to +4 °C or –18 °C, as desired.
In the event of an alarm, the most recent alarm message (e.g. AL1) and the cold store temperature are displayed alternately. Three spot indicators show the switching status of the relays during operation: Pos. 1: On : Compressor relay on. Off: Compressor relay off.
The input parameters are grouped together in two programming levels: Access the first programming level by pressing keys at the same time for 5 seconds. Then use the keys to access the parameters to be changed. Access the second programming level by pressing and the key simultaneously for 5 seconds.
If the set temperature difference E03 is negative, an alarm is given if it is too cold in the refrigerated area, e.g. E03 = –10 K, cold store setpoint = –18 °C alarm at –28 °C in refrigerated area. If the set temperature difference E03 is positive, the alarm is given if it is too warm in the refrigerated area, e.g.

After defrosting has been initiated manually, the next time defrosting takes place is after a complete time interval has elapsed. If the time interval between two defrost cycles is changed when the system is in operation, the new time interval will not be applied until after the next time defrosting has occurred.
8 Maintenance The controller and mains transformer do not require any maintenance. The controller does not have any fuses so, if brief voltage spikes occur, the refrigeration system will not stop operating for a prolonged period. Once the disturbance has passed, the controller will automatically start up again.
Clearing alarm: Press the key. All alarm messages, with the exception of AL2, are also reset by switching off the operating voltage. AL2 can only be reset using key. 10 Problem solving Fault Cause Remedy Evaporator fan does Evaporator sensor T2 Refit not switch on during has fallen out...
