5.4.1 Electric scheme RDC 2
The controller has 3 outputs (230 V), for compressor, fan and drain. The other outputs are for alarm.
The alarm is triggered via opto triac, which can handle 600VAC/50mA.
Controller can also be turned OFF/ON via In. Remote. When the current flows, the controller goes to
OFF state, when the circuit is disconnected, the controller is in ON state. (See the attached scheme
above).
For the MODBUS communication, the twisted pair cable needs to be screwed to the A and B terminals.
To communicate with the PC, an adapter is needed. The address for the MODBUS communication is 1.
