OUTDOOR UNIT OUTDOOR UNIT Error Method: Error Method:
Trip terminal L abnormal
Detective Actuators: Detective Actuators:
Abnormal condition of TR PWB ASSY is
monitored by Control PCB detector circuit.
Detective details: Detective details:
When Trip terminal inside IPM Module becomes Lo At the compressor start - up,
it is judged as a start - up error. LED indicates error and outputs and the error
information to the network.
Forecast of Cause Forecast of Cause: 1. Connection of electrical parts
2. TR PWB ASSY / control PCB defective
3. Check Compressor
Check Point 2 : Diagnosis of Control PCB / TR PWB ASSY Check Point 2 : Diagnosis of Control PCB / TR PWB ASSY
1.Check the supply voltage from Control PCB to IPM
Check DC+15.0V between terminal 1 - 2 of main PWB CN16 (IPM Power supply)
If the voltage does not appear,replace Control PCB
2.Check the voltage at Trip Terminal (To Check TR PWB)
Remove the connector CN14 between TR PWB ASSY - Control PCB.
Check DC+5V between terminal 1 - 2 ,2 - 3 of CN14 (Connector side)
3.Check TR PWB ASSY (Check Transistor Module).
Remove the cable from each terminal and check the continuity.
If any abnormal condition is found, replace TR PWB ASSY.
Check Point 1 : Connection of electrical parts Check Point 1 : Connection of electrical parts
Check if each electrical parts are connected correctly.
Check if Connector CN14 between TR PWB ASSY and control PCB.
Check if TR PWB ASSY has a corrosion or shorted mark.
Rework if connector is incorrectly wired, or loose.
Replace TR PWB ASSY if any abnormal condition is found on PCB.

Check Point 3 : Check Point 3 :
Check Compressor Check Compressor
Check the shortage between each U,V,W terminal and the main unit.
If it is shorted, the compressor is defective
Check the cut off between each U,V,W terminal.
If it is open, the compressor is defective.
