1. Test Item
1) Check the power supply / Check the restart-up after power is reset.
2) Check the compressor and the state of the compressor wire assembling.
3) Check the fault of the single compressor wire.
2. Check
procedure
Yes
30 seconds after power off, power on.
End the service.
No
Check power. /
Check the restart-up after power is reset.
1. Is there any problem in input power?
(Single-phase: 220Vac, 3-phase: 380Vac)
2. Does the error occur again after power rest?
Yes
1. Compressor replacement: If the inter-phase
resistance values of the compressor are
different.
ױ
Power is on.
͑ױ͑
Check the
normal startup.
͑ױ͑
End the service.
2. Wire reassembling: If there is a fault in the
connection of the wires of the compressor
͑ױ͑
Power is on.
͑ױ͑
Check the normal startup.
͑
ױ͑
End the service.
3. Compressor replacement: Serious abnormal
noise (Metallic scraping or grinding noise),
serious vibration
No
Check the compressor
and the state
of the compressor wire assembling.
1. Do the inter-phase resistance values of
the compressor coincide?
(U
׳
V, U
׳
W, V
׳
W)
2. Are the wires on the compressor correctly connected?
(Non-connection, wrong connection)
3. Is there abnormal noise
in the rotation of the compressor?
Replace the compressor.
No
s the resistance between
the compressor body and the chassis
Mega Ω?
Yes
