Troubleshooting
4-44
4-4-16. Compressor starting error / rotation error (Error Code : E461, E467)
1. Test
items
1) Check the power connection. / Check the restart after power reset.
2) Check the compressor and the state of the compressor wire assembling.
3) Check the defective for compressor wire single parts.
2. Check
procedure
Yes
Power on 30 seconds after power off.
End the service.
No
Check the
power connection.
Check the restart after power reset.
1. Is there any problem in input power?
(Single-phase: 220Vac, 3-phase: 380Vac)
2. Does error occur again after
power reset?
Yes
1. Replace the compressor : If the resistance value
between phases of the compressor is different.
ĺ
Power on.
ĺ
Check the normal operation.
ĺ
End the service.
2. Reassemble wire : If the wire connection of the
compressor is wrong.
ĺ
Power on.
ĺ
Check the normal operation.
ĺ
End the service.
3. Replace the compressor : When loud abnormal
noise generates (metal cutting or grinding noise),
or severe vibration.
No
Check the compressor
and connection of compressor wires.
1. Are all the resistance values between phases
matched? (U
ļ
V, U
ļ
W, V
ļ
W)
2. Is compressor wiring normal?
(disconnection, wrong connection)
3. Is there any abnormal noise
from compressor
rotation?
Replace the compressor.
No
Is there a reading of MegaΩ of resistance
between compressor body and chassis?
Yes
