Solution
Comp.P high
High pressure of compressor
If the [HP check dly] is 0, test when the
compressor button has pressed;
If the HP check dly] is not 0, then
compressor runs the test.
Stop compressor only
without affect other
equipments to work.
Check if the input is consistent with
the switch setting.
Comp.P low
Low pressure of compressor
If the [LP check dly] is 0, test when the
compressor button has pressed;
If the [LP check dly] is not 0, then
compressor runs the test.
Comp overload
The compressor overload
Compressor runs the test.
Check if the input is consistent with
the switch setting.
Comp.I high
The current of compressor is
too high
Check if the rated current of
compressor1 is input is reasonable.
Comp.I low
The current of compressor is
too low
Check if the measure tool of the
compressor1 current is connect.
Temp.low AL
The liquid temperature is too
low
Test after cold pump starts
Stop the compressor and
delay to stop the cool
pump, and do not stop the
cold pump.
Check if the Liquid temperature is
lower than the set temperature of
Liquid protection.
T.high warn
The liquid temperature is
higher than the warn value.
If
【
HT detect dly
】
is 0,detect when the
cold pump starts; if
【
HT detect dly
】
is
not 0,detect when the cold pump has
run for set time.
Alarm only without affect
other equipments to work.
Check if the Liquid temperature is
higher than the set temperature of
Liquid warn.
Temp.high AL
The liquid temperature is too
high
If the [Temp.high AL] is set
“Pump keep”,Stop the
compressor and delay to
stop the cool pump, and
do not stop the cold pump;
If the [Temp.high AL] is set
“Pump stop”, Stop the unit
in case of fault.
Check if the Liquid temperature is
higher than the set temperature of
Liquid protection.
Anti-freez.AL
Antifreeze alarm
Power on to test
Stop all the compressor
and cool pump, and do not
Check if the antifreeze input is
consistent with the switch setting.
