will be switched on
•the condenser fan will be switched off
•if the UV light is on (i.e. if cabinet
sterilisation is ongoing),
the UV light will be switched off
PH
High pressure input alarm
-Remedies
:
•check the causes of the input
activation
•see parameter P40
-
Consequences:
•the operational cycle will be interrupted
•the loads will be switched off
•it will not be possible to start any
operational cycles
•the alarm output will be activated
LP
Low pressure input alarm
-Remedies:
•check the causes of the input activation
•see parameter P42
-
Consequences
:
•the operational cycle will be interrupted
•the loads will be switched off
•it will not be possible to start any operational
HA
Compressor thermal protection input
alarm
-Remedies
:
•check the causes of the input
activation
•see parameter P44
Consequences:
•the operational cycle will be interrupted
•the loads will be switched off
•it will not be possible to start any
operational cycles
•the alarm output will be activated
rES
Power failure during an operational cycle
-Remedies:
•check the causes of the input activation
-Consequences:
•the operational cycle will be restored from
the point
where the power failure occurred
When the cause that triggered the alarm has been resolved, the device restores normal
operation
7.2 INTERNAL DIAGNOSTICS
Er0
Cabinet probe error
-Remedies
:
•see parameter P60
•check probe integrity
•check probe-device connection
•check the cabinet temperature
-Consequences
:
•the operational cycle will be interrupted
•the loads will be switched off
•it will not be possible to start any
operational cycles
•the alarm output will be activated
Er1
Evaporator probe error
-Remedies
:
•the same as for the previous case, but in
relation to the evaporator probe
-Consequences:
•defrosting will last for the length of time
set by parameter P24
•the evaporator fan will be switched off
during storage
•the alarm output will be activated
Er3
Needle probe error
-Remedies:
•the same as for the previous case, but in
relation to the needle probe
-Consequences:
•if a set-temperature chilling or freezing
operation is ongoing, the operational cycle
will be interrupted
Er4
Condenser probe error
-Remedies:
•the same as for the previous case, but in
relation to the
condenser probe
-Consequences:
•the condenser fan will operate in parallel
with the compressor, except when set by
