CSd
Compressor shut down alarm.
Solutions:
- check the condenser temperature; see parameter C7
- switch the device off and back on again: if when the device is switched back on, the temperature of the
condenser is still higher than that established in parameter C7, disconnect the power supply and clean the
condenser
Main consequences:
- the compressor and the evaporator fan will be switched off
- 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)
dFd
Defrosting alarm switched off because maximum time has been reached
Solutions:
- check the integrity of the evaporator temperature probe; see parametersd2, d3 and d11
- press a key to restore normal display
Main consequences:
- the device will continue to operate normally
Pd
Pump down alarm (from digital input) finished for maximum duration
Solutions:
- check the integrity of the sensor switching off the compressor
Main consequences:
- the device will continue to operate normally
When the cause of the alarm disappears, the device restores normal operation, except for the following alarms:
- the power supply interruption alarm (code “PF”) which requires the pressing of a key
- maximum pressure switch alarm (code “iSd”) which requires the switching off of the device or the temporary suspension of
the power supply
- compressor blocked by condenser temperature alarm (code “CSd”) which requires the switching off of the device or the
temporary suspension of the power supply
- defrosting alarm switched off because maximum time has been reached (code “dFd”) which requires the pressing of a key.
