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 evaporating pressure; see parameters h12 and h13
- 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)
- the electronic expansion valve will be closed
HSH
High superheating alarm alarm
Solutions:
- check the evaporating temperature; see parameters h02
Main consequences:
- 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)
