Diagnosis Servis
No abnormalities are
observed in the power
supply, but the imbalance
in voltage recurs.
Imbalance in
supplied voltage is
in excess of 6 V.
(
1)
NO
YES
Open phase?
YES
NO
Is the voltage
imbalance applied
to the inverter in
excess of 6 V?
(
2)
YES
NO <When voltage monitoring is possible:>
Using a device capable of
constant recording of power
supply voltage record power
supply voltage between 3
phases (R-S, S-T, R-T) for
about one continuous week.
Explanation for users
In accordance with "notification of inspection results" accompanying spare parts.
Be sure to explain to the user that
there is a "power supply imbalance"
for which DAIKIN is not responsible.

imbalance.
Part or wiring defect
After turning the Catu Daya
OFF, check and repair the
main circuit wiring or parts.
(1) Loose or disconnected
wiring between Catu
Daya and inverter
(2) K2M contact disposition,
fusion or contact is poor.
(3) Loose or disconnected
noise filter
Replace the PCB Inverter.
Catatan:
1. Measure voltage at the X1M Catu Daya terminal block.
2. Measure voltage at terminals R, S and T of the diode module inside the PCB Inverter while
the compressor is running.
Give the user a copy of "notification of inspection results" and leave
it up to him to improve the imbalance.
Power supply voltage imbalance.
Even if the power supply voltage is not
unbalanced when measuring it, there are
many cases where it gets unbalanced during
night-time (around 6:00PM to 10:00PM).
