Always lit
● During normal operation
The LED indicates the drive state of the controller in the outdoor unit.
● 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 [570 V] in the main capacitor will drop to 20 V in approx. 5
minutes (input voltage: 400 V). When servicing, make sure that LED1, LED2 on the outdoor circuit board goes out, and then
wait for at least 5 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.
