1 APPLICATION
Temperature controller MCK-102-14 (hereinafter MCK-102-14) is designed for the control and operation
by deep-freezing machines, commercial refrigeration displays, monoblock units and other similar refrigeration
equipment.
equipment.
Basic functions that performs MCK-102-14are the following:
- temperature control over refrigerated zone;
- automatic defrost by turning OFF the compressor for certain time adjusted by user;
- compressor protection from voltage drops and unallowable voltage fluctuations – this is achieved by
- temperature control over refrigerated zone;
- automatic defrost by turning OFF the compressor for certain time adjusted by user;
- compressor protection from voltage drops and unallowable voltage fluctuations – this is achieved by
permanent control of the acting voltage measurement and control;
- automatic restart of the compressor when the voltage parameters returned back to normal values after
the voltage interruption. Auto-restarting time delay could be adjusted by user as necessary.
-
digital filtration of signal is added from the sensor of temperature (menu item “”).
ATTENTION! If MCK-102-14 is powered by 24V DC, then the power supply unit must necessarily be
galvanically isolated from mains 220V/50Hz voltage (it should withstand testing RMS voltage of 1500V
during 1 minute).
during 1 minute).
Please also pay attention that in case of powering the MCK-102-14 with 24V DC the voltage
monitoring function should necessarily be disabled (parameter
should be set to “0”).
N o t i c e - On special request it is possible to supply the programming device for the
MCK-102-11 to change default factory settings.

3 INSTALLATION AND START UP PROCEDURES
3.1 MCK-102-14 should be installed into the case of refrigeration installation or any other suitable place
that excludes the ingress of moisture inside the case of MCK-102-14.
During installation special attention should be paid so that all wiring connections must be fixed well such a
way to avoid twisting and abrasion of the wires.
4 PREPARING FOR OPERATION
4.1 Connect compressor and temperature sensors to corresponding terminals of MCK-102-14 as shown
one Figure 1.
If the rated power of the compressor is more than 1000W or three phase compressor is being used in
refrigeration installation – then the MCK-102-14 should operate with compressor via contactor. So that MCK-
102-14 will operate with the magnetic coil of the contactor of corresponding rated parameters and contactor
in its turn will commutate (turn ON/OFF) the compressor.
