Pressure sensor error
Hydraulic Unit LED:
Green 8 flashes / Red 6 flashes
Outdoor Unit LED:
flash
Probable causes:
•
Connector connection failure
•
Pressure Sensor failure
•
Main PCB failure
Check:
Clear 24:
OK
3 Check output voltage of Pressure Sensor
Check voltage of Main PCB (Measure at Main PCB side connector)
2 pin(White) - 3 pIn(Black) Voltage is refer to the following graph
If the voltage is not correct, replace Presure Sensor
OK
1 Check connection of the Pressure Sensor:
- Check if the terminal connection is loose
- Check if connector is removed
- Check if connector is erroneous connection
- Check if cable is open
Upon correcting the removed connector or mis-wiring, reset the power
Voltage [V]
Pressure [MPa]
2 Check output voltage of Main PCB :
Check voltage of Main PCB (Measure at Main PCB side connector)
1 pin(Red) - 3 pin(Black) DC5V +/- 5%
