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” issued  
by the ZVEI (German Central Association for the Electrotechnical  
Industry) shall apply.  
Before disposing of the packaging, please check it for loose functional  
parts and information leaflets.  
So that we can process warranty claims, please give an exact  
description of the defect (with a photograph, if appropriate) and state  
the model designation of the unit.  
Please keep these operating instructions at the place where the  
equipment is used.  
2 General instructions  
Work on the electrical devices and switching equipment may only be  
carried out by appropriately qualified personnel. The relevant safety  
and environmental regulations must be followed.  
FLICA equipment is free from PCBs, PCTs, asbestos, formaldehyde,  
cadmium and water-repelling substances.  
The design of the equipment has taken into account the Standards EN  
50081-1,2 (emitted interference), EN 50082-1 (immunity to  
interference), EN 60335-1 (electrical safety),  
IEC 695-2-1 to -2-3 (fire resistance, glow-wire test).  
Safety tests have been performed in the factory on all equipment in  
accordance with EN 60335-1  
(DIN VDE 0700 T500).  
3 Use and Function  
3.1 Use for the purpose intended  
¼
This controller is designed to control ambient and media  
temperatures in cold stores and refrigeration systems and to  
control existing defrost equipment for one refrigeration circuit in  
each case.

¼
The controller must not be used as a safety cut-out device or excess  
temperature limiter.  
If the controller is used for purposes other than those stated  
here, it shall not be considered to be use for the purpose  
intended.  
¼
Only connect sensors supplied with the unit. If a replacement sen-  
sor is required, only use sensors of the same type (part no. H61007).  
The controller is not intended for use in vehicles because the  
possible operating voltage ranges, interference level and  
environmental operating conditions exceed the limits for which the  
controller can be used.  
¼
¼
Please take the application limits into account  
(see Technical Data, chapter 12).  
3.2 Function  
The PCR-300 is a microprocessor-controlled cold store control for  
refrigeration and deepfreeze systems with a modular housing for  
installation on 35 mm standard rails.  
¼
Compressor control (dependent upon cold store  
temperature) with delayed start-up.  
Evaporator fan control  
¼
Fan either in combination with compressor or  
operating continuously or  
switched via the evaporator thermostat.  
Defrost control limited thermostatically,  
either for electrical heating or hot-gas defrosting  
Alarm output.  
¼
¼
Defrosting is initiated via programmable intervals of time, max. 24/day.  
The PCR-300 RC is provided with a real-time clock with a  
back-up battery for defrost control. A maximum of six times per day  
can be programmed.  
4 Safety  
4.1 Sources of danger  
¼
¼
Caution - Mains voltage.  
Never expose the unit 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.  
¼
Even if the control-circuit voltage is switched off, high voltage may  
still be applied to the unit. For this reason, isolate all electric  
circuits before starting any service work.  
4

¼
¼
Never expose the unit to excessive heat, dust and vibrations. Avoid  
knocks and pressure loads. If the housing is damaged, there is a risk  
of an electric shock causing death or injury.  
If the unit cannot be operated without the risk of danger, it must  
be taken out of service and precautions taken so that it cannot be  
switched on again unintentionally.  
This applies, in particular, if:  
The housing has damage which is visible,  
the unit is no longer operational or  
it has been stored for a long time in unfavourable conditions.  
¼
The unit must not be opened. If it is thought that the unit may be  
defective, send it back to the dealer or manufacturer with a precise  
description of the fault.  
4.2 Safety precautions  
¼
All electromagnetic loads (solenoid valves, contactors, alarm horns,  
motors) should be interference suppressed directly at the coil with  
RC elements.  
¼
Please note the maximum contact rating of the relays and  
terminals.  
If this is not observed, there is a risk that the contacts may pit or  
stick, with the result that the refrigeration system will not operate  
correctly and the refrigerated items may be damaged.  
¼
¼
¼
¼
Sensor leads are to be routed separately from mains voltage wires.  
The clearance should be at least 5 cm.  
Sensor leads must not be routed in multiple cables with other leads  
carrying mains voltage, otherwise the system may malfunction.  
Tighten the terminals carefully; excessive strain will result in  
damage to the controller.  
PCR-300RC: Set DIP switch 2 to “off” if the controller is going to  
be out of service for more than 3 months and when the controller  
is shipped. This is to prevent damage occurring to the back-up  
battery.  
5 Installation and commissioning  
5.1 Mechanical installation  
¼
4 Din standard modular housings to be mounted on a  
standard rail:  
5
Download from Www.Somanuals.com. All Manuals Search And Download.  
a) housing with 2 mounting tabs:  
open out the lateral mounting tabs; clip the unit on the 35 mm rail  
and press tabs in again.  
b) housings with 1 mounting tab:  
put housing on the upper 35 mm rail. Clip the unit on the 35 mm  
rail, lower tab clips on the rail automatically. To remove the unit  
from the rail press in lower mounting tab with a screw driver, lift  
unit.  
¼
Mounting of sensor:  
¼
Use a cable clamp to secure sensor T1 in a suitable position.  
¼
Secure evaporator sensor T2 in the evaporator fin core at the point  
where it is suspected icing is the greatest. It is advisable to use a  
point in the lower third of the finned evaporator.  
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.

Instructions:  
¼
¼
¼
Pay attention to the contact loading of the relay  
(8A / 5A resistive load, 2A / 1A inductive load). As a general rule,  
contactors are recommended.  
The maximum tested sensor cable length is 50 m, with a minimum  
2
cross section of 2 x 0.75 mm . Solder the extension cable to the  
sensor cable to prevent contact resistances.  
It is advisable to use shielded sensor extension cables.  
All shields must be routed at the side of the controller to one  
earth/protective potential. The extension cable shield must not be  
connected on the sensor side, otherwise bonding currents may  
occur via the shielding.  
¼
The controllers are designed respecting the highest degree of  
immunity to interference. If the local interference level exceeds the  
immunity data might get lost (AL1 in display) and the controller  
switches to the preprogrammed setting values. This is not a  
mulfunction of the controller. In such cases the means to suppress  
interference have to be improved (RC-elements, shielded lines).

5.3 Setting the DIP switch for the emergency setpoint and the  
clock back-up battery  
Carefully lift the housing cover off the side, using your fingers.  
¼
Selection of the emergency setpoint for the cold store  
temperature:  
This will be activated if the data in the memory is lost and 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. This ensures that chilling systems with  
temperatures above zero do not freeze and deepfreeze  
installations do not thaw.  
DIP switch 1 (left), Pos.: off (bottom): Setpoint value at +4 °C for  
emergency operation.  
Advisable for chilled storage  
(= Preset value).  
Pos.: on (top):  
Setpoint value at –18 °C for  
emergency operation.  
Advisable for deepfreezers.  
For PCR-300 RC only:  
The back-up battery must be switched on when the controller is started  
up so that the real-time clock keeps operating if there is a power failure.  
Activation of the back-up battery:  
DIP switch 2 (right), Pos.: off (bottom): Battery switched off when  
controller is stored or in transit. (The battery is  
switched off when the controller is delivered;  
exhaustive discharge monitoring).  
Pos.: on (top): Battery activated.

Note: It takes approximately 24 hours for the battery to achieve its  
full back-up capacity.  
The battery will provide cover for a power failure of approximately  
1 month.  
6 Operation of the controller  
Front view of controller:  
6.1 Switching on the operating voltage  
The controller is started by means of a control switch provided by the  
customer.  
The first time the controller is started, pre-programmed setting values  
are used which at later point can be adapted for individual  
requirements.  
If alarm “AL 2” (temperature in refrigerated chamber too high  
or too low) is displayed when the controller is switched on, this  
can be cleared by pressing the  
key.  
6.2 Display  
During normal operation the current cold store temperature is  
displayed. It is measured with cold store sensor T1.  
In the event of an alarm, the most recent alarm message (e.g. AL1)  
and the cold store temperature are displayed alternately.

7.2 Sensor calibration (parameters E15 and E16)  
The cold store and evaporator sensors can be calibrated.  
Note:  
An additional resistance of 7 in each case,  
caused by the extension of the sensor cable,  
results in a change in the temperature display by  
+1K.  
How to proceed: Measure the temperature at the sensor concerned  
with a calibrated thermometer or submerge the  
sensor in well mixed iced water (0 °C).  
Compare the measured temperature with the  
temperature displayed on the unit display.  
If the measured temperature is lower than the  
one displayed, set the negative difference as the  
programming value  
(e.g. - 2 K).  
If the measured temperature is higher than the  
one displayed, set the positive difference as the  
programming value  
(e.g. 2 K).  
The temperature display is then corrected by the  
set value.

8 Maintenance  
The controller does not require any maintenance. It 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.  
Cleaning the housing: Only a dry anti-static cloth may be used to wipe  
clean all plastic parts. Do not use water or cleaning agents containing  
solvents!
