NOTE: Also the “cPr2”, “InC2”, “dGs”, “inC1”, ”and “dGSt” values are present. These values must
not be used.
According to the oA2, oA3, oA4, oA6 configuration, 2 kinds of plant can be defined:
Rack with compressors only: all the oAi different from FAn and inF
Rack with compressors and fans: both FAn and CPr are used for oAi.
NOTE: COMPRESSOR WITH STEPS CONFIGURATION: the output of compressor has to be
set before the output of the step.
ES. Compressor with 1 step: oA2 = cPr1, oA3= StP.
If an oAi set as step without any previous oAi set as cPr the configuration alarm “CStP”
will be activated.
PLANT CONFIGURATION EXEMPLES:
Plant with 2 compressors
(one of them digital) e 2 fans:
oA1 = dgS
oA2 = CPr1
oA3 = FAn
oA4 = FAn
oA6 = nu
Plant with 4 compressors
without fans:
oA1 = dgS
oA2 = CPr1
oA3 = CPr1
oA4 = CPr1
oA6 = nu
Plant with 1 compressor and
3 fans:
oA1 = dgS
oA2 = FAn
oA3 = FAn
oA4 = FAn
oA6 = nu
