SIMPLE CHECK POINTS FOR DIAGNOSING FAULTS

Check items		Diagnosis result

1	OPERATION	Check to see if OPERATION indicator goes on and off when the main switch
	indicator	or breaker is turned on.

2	Terminal	Check the power supply voltage between	1	- 2 (Refer to the name plate.)
	block	Chack the fluctuate voltage between 2 -	3	(DC15 to 60V)

3	Fuse	Check to see if the fuse blows out. (Check the varistor. : R22, R21)
	6.3A

4	DC 5V	Check the voltage at the No.8 pin on CN13 connector of the infrared receiver.
		(Check the transformer and the power supply circuit of the rated voltage.)

5	DC 12V	Check the voltage at the brown lead of the louver motor.
		(Check the transformer and the power supply circuit of the rated voltage.)
