iSd
Maximum pressure switch alarm
Solutions:
-
check the causes of the activation of the input; see parameters i5, i6, i7, i8, i9, i15 and i16
-
switch off and re-start the device or suspend the power supply
Main consequences:
-
the regulators will switch off
-
the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
LP
Minimum pressure switch alarm
Solutions:
-
check the causes of the activation of the input; see parameters i5, i6, i15, i16 and i17
Main consequences:
-
the compressor will be switched off
-
the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
C1t
Compressor thermal protection alarm
Solutions:
-
check the causes of the activation of the input; see parameters i5, i6, i15 and i16
Main consequences:
-
the compressor will be switched off
-
if parameter u1 and/or parameter u11 is set at 7 (or in case of operation with two compressors), the device
shall operate exactly as it would with only one compressor (compressor 2)
-
the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
C2t
Compressor 2 thermal protection alarm
Solutions:
-
check the causes of the activation of the input; see parameters i5, i6, i15 and i16
Main consequences:
-
compressor 2 will be switched off (only if the parameter u1 and/or parameter u11 is set at 7)
-
the device shall operate exactly as it would with only one compressor (compressor 1)
-
the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
MiC
Man in Cold room alarm
Solutions:
-
check the causes of the activation of the input; see parameters i5, i6, i15 and i16
Main consequences:
-
the man in cold room output will be switched on (only if the parameter u1 and/or parameter u11 is set at
12)
-
the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
COH
Condenser overheated alarm
Solutions:
-
check the condenser temperature; see parameter C6
Main consequences:
-
the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
-
the condenser fan will be on (only if parameter u1 and/or parameter u11 is set at 6)
