Always lit
2.During normal operation
The LED indicates the drive state of the controller in the outdoor unit.
3.When fault requiring inspection has occurred
The LED alternately indicates the inspection code and the location of the unit in which
the fault has occurred.
NOTES:
1.Refer to the wiring diagrams of the indoor units for details on wiring of each indoor unit.
Self-diagnosis function
The indoor and outdoor units can be diagnosed automatically using the self-diagnosis switch
(SW1) and LED1, LED2 (LED indication) found on the multi-controller of the outdoor unit.
LED indication : Set all contacts of SW1 to OFF.
Cautions when Servicing
!
•
WARNING: When the main supply is turned off, the voltage [340 V] in the main capacitor will drop to 20 V in approx.
2 minutes (input voltage: 230 V). When servicing, make sure that LED1, LED2 on the outdoor circuit board goes out, and then
wait for at least 1 minute.
•
Components other than the outdoor board may be faulty: Check and take corrective action, referring to the service manual.
Do not replace the outdoor board without checking.
