Checking the Fan Board Error Detection Circuit at No Load
Items to be checked
Phenomena
Remedy
(1)
Operate the outdoor unit.
1)
BUS voltage does not boost (does
not change)BUS voltage does not
boost to approximately between
650 and 750 VDC, or the following
errors are detected.
Error code : 4220
Detail code : 123
Replace the inverter board.
(2)
Check the BUS voltage after the
converter circuit went into oper-
ation and the BUS voltage has
boost. *The voltage generally
boost at or above 60 rps, de-
pending on the power source
voltage.
2)
An overcurrent error occurs after
converter circuit goes into opera-
tion.
Error code : 4250
Detail code : 121,122
a.If the problem persists after startup, re-
place the inverter board.
b.If the problem persists after replacing
the inverter board, replace the DCL.
3)
An overvoltage error occurs after
converter circuit goes into opera-
tion.
Error code : 4220
Detail code : 109,110,112
a.If the problem persists after startup, re-
place the inverter board.
b.If the problem persists after replacing
the inverter board, replace the DCL.
4)
No problems were found with items
1) through 3).
Normal
Items to be checked
Phenomena
Remedy
Remove fan motor winding. Check
insulation resistance and coil resis-
tance.
1)
Fan motor insulation failure.
If < 1 MΩ, Defect.
Change fan motor.
2)
Fan motor wire failure.
Target coil resistance: Approx. 10 Ω.
(Changes with temperature)
Change fan motor.
Items to be checked
Phenomena
Remedy
(1)
Turn off breaker.
*Turn power off without fail.
1)
Electrical current over load error.
Check code: 4255, 4256
Detail code: 101, 104
Change fan board.
(2)
Remove fan board CNINV
and CNSNR connectors.
2)
Logic error
Check code: 4225, 4256
Detail code:111
Change fan board.
(3)
Turn on breaker.
3)
Position error on start up
Check code: 5305, 5306
Detail code: 132
Normal
*After checking, return connector
CNINV & CNSNR.
(4)
Operate unit.
