rel. 1.0
Pa. 20 / 23
5 - 6 Low pressure-switch input: input at the same voltage of loads. The input is activated by
supplying (SEP=1) or by opening (SEP=0) the terminals.
6 - 8 Liquid level input: input at the same voltage of loads. The input is activated by supplying
the terminals.
9 - 10 Terminals supply.
13 - 14 Reduced set input: free voltage input. The input is activated by closing (rSIP=1) or by
opening (rSIP =0) the terminals.
14- 15: Suction NTC probe input (PbC=ntc)
15 - 17: Suction 4÷20mA probe input (PbC=Cur)
18-19-20: Outputs for serial RS485 .
22 – 33 Digital inputs for safeties of compressors. When an d. i. is activated, the
corresponding output is switched OFF.
44 – 55 Relay configurable outputs for compressors. The compressors are always allocated
starting from left to right.
E. I. Cpnu=4 The terminals 44-45 are for the first compressor; 46-47 are for the second
compressor; 48-49 are for the third compressor; 50 - 51 are for the fourth compressor.
