NOTE: CONFIGURATION OF COMPRESSOR WITH UNLOADERS (STEPS): the output of
compressor has to be set before the output of its unloaders (steps).
ES. Compressor with 1 unloader: oA1 = cPr, oA2= StP.
If compressor with different capacities are used (CtyP=dPo), all the oAi must to be configured as
cPr (compressor) otherwise the configuration alarm “CStP” will be activated.
If an oAi is set as step without any previous oAi set as cPr the configuration alarm “CStP”
will be activated.
PLANT CONFIGURATION EXAMPLES:
Plant with 3 compressors 2
fans default configuration
with PP11, PP30 pressure
transducers:
oA1 = CPr1,
oA2 = CPr1,
oA3 = CPr1,
oA4 = FAn,
oA5 = FAn,
oA6 = nu
Plant with 4 compressors
without fans:
oA1 = CPr1,
oA2 = CPr1,
oA3 = CPr1,
oA4 = CPr1,
oA4 = nu
oA6 = nu
Plant with 1 frequency
compressor + 2 standard
compressors and inverter
for fans:
oA1 = InC1,
oA2 = CPr1,
oA3 = CPr1,
oA4 = nu,
oA5 = INF,
oA6 = nu,
AOC = tEn
AOF = InC1
2AOC = tEn
2AOF = inF
