E02
There is air in the system and intermittent
bubbles in the liquid scope
Implement vacuum and recharge with refrigerant
E03
High suction superheat
Slowly release and recover part of the refrigerant from the
liquid pipe stop valve to prevent excessive oil loss.
There is air in the system and intermittent
bubbles in the liquid scope
It needs to be vacuumed and refilled with refrigerant
Alarm code Fault Analysis
Alarm Code Fault Analysis table
E01
High suction superheat
Verify that the refrigerant is sufficient and adjust the
opening of the expansion valve until the suction superheat
is controlled within a reasonable range.
E05
Condensation sensor fault
Check wiring or replace sensor
E07 Compressor motor fault
High ambient temperature, no much air flow
mprove ventilation conditions to ensure adequate ventilation
space around the unit
E04 Discharge sensor fault
Check wiring or replace sensor
High pressure switch action
The condenser is dirty
Clean the condenser
Globe valve or other valve forgot to open
Confirm valve opening status one by one according to system
diagram
The compressorrunning beyond the range
Reconfirm the matching parameters of the compressor, or
change the type of the unit
Poor lubrication, lack of lubricating oil,
increased running resistance
Make-up lubricant oil
severe wear compressor
Replace the compressor and confirm whether the system has
the problem of oil return
Lack of refrigerant
Replenish refrigerant
Suction pressure too low,amd below operating
range
Adjust the pressure controller to control the operating
range of the compressor
Over current alarm
High ambient temperature, no much air flow
mprove ventilation conditions to ensure adequate ventilation
space around the unit
Failure of spray cooling system
Check liquid injection solenoid valve, liquid injection
expansion valve, and liquid injection capillary
Check the compressor to make sure the high and low pressure
are in the air
Discharge Temp Abnormal
Condenser Dirty Clean the condenser
Low charge quantity or refrigerant leakage
Confirm valve opening status one by one according to system
diagram
