OR PROTECTION
FAILURE CAUSE
AND CORRECTIVE ACTION
1. The T3 sensor connector is loosen. Reconnect it.
2.The T3 sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive.
3. The T3 sensor failure, change a new sensor.
The condenser outlet
refrigerant temperature sensor
(T3)error.
1.Check the power supply cables should be conneted
stable,aviod phase loss.
2.Check whether the sequence of neutral wire and live wire are
connected reversely. Phase loss or neutral wire and
live wire are connected
reversely(only for three phase
unit)
1. The T4 sensor connector is loosen. Reconnect it.
2.The T4 sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive.
3. The T4 sensor failure, change a new sensor.
The ambient temperature
sensor (T4) error.
1. The Th sensor connector is loosen. Re connect it.
2.The Th sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive.
3. The Th sensor failure, change a new sensor.
Suction temperature
sensor(Th) error
1. The Tp sensor connector is loosen. Re connect it.
2.The Tp sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive
3. The Tp sensor failure, change a new sensor.
Discharge temperature
sensor(Tp) error
1. Whether there is power connected to the PCB and driven
board. Check the inverter module PCB indicator light is on or
off. If Light is off, reconnect the power supply wire.
2.if light is on, check the wire connection between inverter
module PCB and main control board PCB, if the wire loosen or
broken, reconnect the wire or change a new wire.
3. Replace a new main PCB and driven board in turn.
Communication error between
inverter module PCB A and
main control board PCB B
The sum of the number of times L0 and L1 appear in an hour
equals three.See L0 and L1 for fault handling methods
Three times P6(L0/L1) protect
1.wire doesn’t connect between main control board PCB B and
main control board of hydraulic module. connect the wire.
2.Communication wire sequence is not right. Reconnect the
wire in the right sequence.
3. Whether there is a high magnetic field or high power
interfere, such as lifts, large power transformers, etc.. To add a
barrier to protect the unit or to move the unit to the other place.

main board PCB B and main
Control board of hydraulic
