 CompressorA hermetically sealed compressor is used in the refrigerationunit. The compressor is equipped with overload protectionwhich trips on the compressor temperature and compressorcurrent consumption. CondenserDepending on the device type, an air-cooled or water-cooledcondenser is used in the refrigeration unit. In air-cooled con-densers, the condensation heat is discharged to the environ-ment. The fresh air is sucked in through the front of the deviceusing a fan, heated and discharged on the rear of the device.In water-cooled condensers, the condensation heat is dis-charged via cooling water. EvaporatorIn the internal bath, heat is discharged using a pipe coil evapo-rator.Technical information for the refrigeration unit can befound inÄ on page 61.3.4.6 InterfacesNote the following: The equipment connected to the low voltage inputs and out-puts must have safe separation from dangerous voltagesaccording to DIN EN 61140 such as by double or reinforcedinsulation according to DIN EN 60730-1 or DIN 60950-1.Specific functions of the device such as the setpoint temperaturecan be controlled with the RS232 interface using a PC. Thus,custom programs for controlling the device can be developed.Further information about the connection and configura-tion can be found inÄ Chapter 6.7.1 ‘ConfiguringRS232 interface’ on page 44.Changeover contact which switches in the event of a device fault.For example, faults can be registered on a system.Using the display, it can be set in which fault situationsa signal is output via the interface.RS232 interfaceAlarm outputDesign and functionMicrocool 21
