C1… C15 Relay 1…15 configuration: by means of parameter C0 and C1…C15 the plant can be
dimensioned according to the number and type of compressors and/or fans and the number of steps
for each one.
Each relay according to the configuration of the C(i) parameter can work as
Frq1 = frequency compressor circuit 1;
Frq2 = frequency compressor circuit 2;
CPr1 = compressor circuit 1;
CPr2 = compressor circuit 2,
Screw1 = screw compressor – circuit 1
Screw2 = screw compressor – circuit 2
StP = step of the previous compressor,
FrqF1 = inverter fan circuit 1;
FrqF2 = inverter fan circuit 2;
FAn1 = fan circuit 1,
FAn2 = = fan circuit 2,
ALr = alarm;
ALr1 = alarm 1
ALr2 = alarm 2
AUS1 = auxiliary output 1
AUS2 = auxiliary output 2,
AUS3 = auxiliary output 3,
AUS4 = auxiliary output 4,
onF = on / off relay
nu = relay not used
NOTE 1: CIRCUITS WITH INVERTER FOR COMPRESSORS OR FANS
If in one circuit there are frequency compressors (Frq1 or Frq2) inverter fans, (Frq1F or
Frq2F) their relays must be the first of that circuit.
ES: Plant with 1 circuit with 6 compressors (1 with inverter and 5 fans with inverter):
C0 = 1A1d;
C1 = Frq1;
C2 = CPr1;
C3 = CPr1,
C4 = CPr1,
C5 = CPr1;
C6 = CPr1;
C7 = Frq1F;
