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), LED1 and 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 and 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.
