Evaporator probe error.
To correct:
-
the same as for the cabinet probe error but with reference to the evaporator probe.
Main results:
-
if parameter P4 is set to 1, defrosting will last for the time set by parameter d3
-
parameter F1 will have no effect
-
the alarm output will be activated
Condenser probe error.
To correct:
-
the same as for the cabinet probe error but with reference to the condenser probe.
Main results:
-
the condenser fan will operate in parallel with the compressor
-
the condenser overheat alarm will never be activated
-
the compressor locked alarm will never be activated
-
the alarm output will be activated
Needle probe error.
To correct:
-
the same as for the cabinet probe error but with reference to the needle probe.
Main consequences if parameter P3 is set to 1:
-
if the error occurs during stand-by, the temperature controlled cycles will be started up
as time-controlled
-
if the error occurs during temperature controlled blast chilling, blast chilling will last for
the time set by parameter r1
-
if the error occurs during temperature controlled blast freezing, blast freezing will last
for the time set by parameter r2
-
if the error occurs during needle probe heating, the heating will be interrupted
-
the alarm output will be activated
Thermal switch alarm
To correct:
-
check the condition of the multi-purpose input
-
check the value of parameter i6.
Main results:
-
the cycle underway will be interrupted
-
the alarm output will be activated
High pressure alarm.
To correct:
-
check the condition of the multi-purpose input
-
