Plant with 3 compressors
suction 1 , 3 compressors
suction 2, with inverter for
fans:
oA1 = CPr1,
oA2 = CPr1,
oA3 = CPr1,
oA4 = CPr2,
oA5 = CPr2,
oA6 = CPr2,
AOC = tEn
AOF = InF
CtyP
Compressor type: it sets if compressors have the same power (homogeneous) or not.
SPo = compressors with same capacity
dPo = compressor with different capacities .
Scr = screw compressors.
StP Valve outputs (unloader) polarity: polarity of the outputs for capacity valves. It
determines the status of the relays associated with the capacity valves (only for
homogeneous and stepped-capacity compressors)
oP =valve activated with open contacts of the relay;
cL = valve activated with close contacts of the relay.
PC1..PC6 Capacity of compressor 1...6: for setting the capacity of single compressors.
It’s
used only if CtyP=dPo.
Insert in each parameter the capacity of the compressor used.
E.I. 3 compressors with following capacity: 10, 20, 40 HP. The parameters have to be set
in this way: PC1=10, PC2=20, PC3=40.
FtyP : Refrigerant type : set the kind of gas refrigerant used in the plant:
