A LINE OF POWER AND CONTROL PANEL WITH DATALOGGER FUNCTION FOR CONTROL OF THE EVAPORATING UNIT ONLY

A line of power and control panels for refrigeration systems to control only the three-phase evaporating unit where units are served by a central refrigerator or remote condenser unit and Datalogger function. A large backlit LCD allows for simultaneous display of ambient temperature, evaporator temperature, calendar and all other refrigeration system information. The temperature recorder is independent from the controller used to manage the refrigeration system and can record (for up to year) ambient temperature and relative alarms through an electronic circuit equipped with autonomous power and temperature sensor (as per EN 12830). The recorder can be removed or replaced without any interruption to normal cold room operation. Moreover, defrosts can be carried out in real time clock mode and it is possible to connect up to the TeleNET supervision system. Magnetothermic protection and motor circuit breaker for the compressor accessible from the front panel linked to an innovative form makes it a perfect and functional choice.

Applications
Control of evaporating unit with electrical defrost up to 12 kW.

Options
SD (Secure Digital™) memory for transfer of temperature recordings onto personal computer.
RS version with thermostat door heater and discharge heater.

Main characteristics
Enable for motor condenser unit, defrosting elements, evaporator fans, solenoid valve, room light and all standard-compliant electrical safeguards.
Magnetothermic circuit breaker accessible from the front panel, which cuts the general power supply.
Differential magnetothermic dedicated to room light accessible from the front panel (see the table).
Easy wiring on the internal terminal block.
Auxiliary relay with activation configurable by parameter.
Transparent cover for access to all the protections, all with IP65 protection rating.
Control electronics with large backlit LCD and user-friendly keypad.
Simultaneous display on LCD of ambient temperature, evaporator temperature, calendar and system status.
Recording of ambient temperature and relative alarms (up to 1 year) with recorder independent from cold room system control.
Secure Digital™ slot built into controller for data downloads.
Defrosts can be carried out in real time clock mode.
RS485 for connection to TeleNET industrial supervision network.
TeleNET SD software to download data on personal computer (provided free of charge with product).
