Leakage/Over
Water
Air conditioning overflow
alarm, high condensate water
level triggers the water level
switch caused by poor
drainage or heating failure of
the evaporation device.
The alarm will automatically
reset when the water is drained
out and the condensate level
drops below the water level
switch.
HP/HD Switch
Alarm
An alarm will be triggered if
the discharge pressure is
higher than the pressure
switch value.
After the pressure returns to the
set value, it will be reset
automatically for 3 times. If it
exceeds 3 times, it will not be
reset automatically and manual
reset is required on the HMI.
Suction Pressure
Sensor Failure
The suction pressure sensor
failed to detect the pressure
which is located on the
suction pipe of the
compressor.
After checking the wiring or
refrigerant leakage pressure
returns to normal, it needs to be
reset manually.
Discharge
Pressure Sensor
Failure
The discharge pressure
sensor failed to detect the
pressure which is located on
the discharge pipe of the
compressor.
After checking the wiring or
refrigerant leakage pressure
returns to normal, it needs to be
reset manually.
Suction
Temperature
Sensor Failure
The suction temperature
sensor failed to detect the
temperature which is located
on the suction pipe of the
compressor.
After checking that the wiring or
