IPM module protection EE11
1. Data mistake
2. Wrong compressor phase connection
3. Compressor liquid and oil accumulation
lead to the current becomes larger
4.Poor heat dissipation of drive module or
high ambient temperature
5. Compressor or driver board damaged
1. Program error, turn off electricity
supply and restart after 3 minutes
2. Check compressor sequence
connection
3. Check the pressure of system by
pressure gauge
4. Check if the ambient and water
temperature is over high
5. If it is the refrigeration system failure,
send it to the service center
6. Change driver board
VDC voltage too low
protection
EE12
1. Mother line voltage is too low
2. Driver board is damaged.
1. Check if the power supply is in the
normal range
2. Change driver board
Input current over high
protection.
EE13
1. The compressor current is too large
momentary
2. The water flow is abnormal
3. Power fluctuations within a short time
4. Wrong reactor
1. Check the compressor if it works
normally
2. Check the plumbing system
3. Check if the power is in the normal
range
4. Check if the reactor is used correctly.
IPM module thermal
circuit is abnormal
EE14
1. Output abnormity of IPM module thermal
circuit
2. Fan motor is abnormal or damaged
3. Fan blade is broken
1. Check if the motor speed is too low or
fan motor is damaged, replace with a
new one.
2. Replace a new driver board
3. Change the fan blade if it is broken.
IPM module
temperature too high
protection
EE15
1. Output exception of IPM modulethermal
circuit
2. Fan motor is abnormal or damaged
3. Fan blade is broken
4.The screw on driver board is loose
1. Check the main board or replace the
driver board
4. Check if the motor speed is too low or
fan motor is damaged, replace it by a
new one if there is any failure.
5. Change the fan blade if it is broken
2. Check the screw on driver board
PFC module protection EE16
1. Output exception of PFC module
2. Fan motor is abnormal or damaged
3. Fan blade is broken
4. Input voltage leap, input power is
abnormal
1.
Check the main board or replace the
driver board.
2.
Check if the motor speed is too low or
fan motor is damaged, replace it by a
new one.
3.
Change the fan blade
4.
Check the input voltage
