Compressor shut down alarm
Solutions:
- check the condenser temperature; see C7 parameter
- switch the device off and back on again: if when the device is switched back on, the temperature of the condenser is still
CSd
higher than that established in C7 parameter, disconnect the power supply and clean the condenser
Main consequences:
- the compressor will be switched off
- the alarm output will be switched on
- the condenser fan will be switched on
Compressor thermal protection alarm
Solutions:
- check the causes of the activation of the multifunction input; see i5 and i6 parameters
Cth
Main consequences:
- the compressor will be switched off
- the alarm output will be switched on
Global thermal protection alarm
Solutions:
- check the causes of the activation of the multifunction input; see i5 and i6 parameters
- check that the cause that triggered the alarm has been eliminated and switch the device off and back on again or
th
sdisconnect the power supply
Main consequences:
- all utilities will be switched off
- the alarm output will be switched on
Defrost alarm switched off because maximum time has been reached
Solutions:
- check the integrity of the evaporator probe; see d2, d3 and d11 parameters
dFd
- touch a key to restore normal display
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 compressor blocked alarm (code "CSd") and the global thermal protection alarm (code "th"), which both need to be reset by turning
the device off or switching off the power supply.
- defrost alarm switched off because maximum time has been reached (code "dFd") which requires the touching of a key.
CODE MEANING
Room temperature probe or inlet air probe error
Solutions:
- check that the probe is the PTC or NTC type; see P0 parameter
- check the device-probe connection
- check room temperature/CPT temperature
Main consequences:
Pr1
- compressor activity will depend on C4 and C5 parameters
- if the P4 parameter is set at 3, the temperature associated with the regulation and the temperature alarms shall be the
outgoing air temperature
- the defrost will not be activated
- the alarm output will be switched on
- the door heating elements shall be turned off
- the neutral area operation heating elements will be turned off
Evaporator probe error
Solutions:
- the same as in the previous example, but with regard to the evaporator probe
Main consequences:
Pr2
- if P3 parameter is set at 1, the defrost interval will last for the amount of time set with d3 parameter
- if P3 parameter is set at 1 and d8 parameter is set at 2 or to 3, the device will operate as if d8 parameter were set at 0
- if P3 parameter is set at 1 or 2 and F0 parameter is set at 3 to 4, the device will operate as if parameter were set at 2
- the alarm output will be switched on
Condenser probe error, critical temperature probe or outflowing air probe
Solutions:
- the same as in the previous example, but with regard to the condenser probe, the critical temperature probe or the
outflowing air probe
Main consequences:
- if P4 parameter is set at 1, the condenser overheated alarm (code "COH") will never be activated
Pr3
- if P4 parameter is set at 1, the compressor shut down alarm (code "CSd") will never be activated
- if P4 parameter is set at 1, the condenser fan shall work in parallel with the compressor
- if the P4 parameter is set at 3, the temperature associated with the temperature alarms shall be the inflowing air
temperature
- the alarm output will be switched on
When the cause of the error disappears, the device restores normal operation.
