stop the cold pump.
Probe break
The liquid temperature sensor
is break
Check if the temperature probe is in
proper contact.
Probe short
The liquid temperature sensor
is short
Cool overload
The cool pump or fan overload
Test after Cool pump starts
Stop compressor and cool
pump or fan only
Check if the fan1 overload input is
consistent with the switch setting.
Cool.I high AL
The current of cool pump or
Fan is too high
Check if the rated current of cool is
input is reasonable.
Cool.I low AL
The current of cool pump or
Fan is too low
Check if the measure tool of the cool
current is connect.
Cool W.flow AL
Lack of cool water flow
Test after the cool pump starts for [Cool
on delay] time.
Stop compressor and cool
pump or fan only.
Check if the cool water flow input is
consistent with the switch setting.
Cold W.flow AL
Lack of cold water flow
Test after the cold pump starts for
[Pump on delay] time
If the [Lack of water] is set
“Pump keep”, Stop
compressor and cool
pump in case of fault.
If the [Lack of water] is set
“Pump stop”, Stop the unit
in case of fault.
Check if the cold water flow input is
consistent with the switch setting.
Pump overload
The cold pump overload
Test after cold pump starts
Stop the unit
Check if the cold pump overload
input is consistent with the switch
setting.
Pump I high AL
The current of cold pump is
too high
Check if the rated current of cold is
input is reasonable.
Pump I low AL
The current of cold pump is
too low
Check if the measure tool of the cold
current is connect.
Phase AL
The three-phase power input
is alarm
Power on to test
Stop the unit
Check if there is default phase or
anti-phase in the three-phase power
input and if the switch is correct.
Water lv.AL
The water level is low
Power on to test
If the [Low liquid lv] is set
“Pump keep”, Stop
compressor and cool
pump in case of fault.
Check if the water level input is
consistent with the switch setting.
