Table 4-1-1 Simple check points for diagnosing faults

Check items	Diagnosis result
OPERATION	Check to see if the OPERATION indicator goes on and off when the main
	switch or breaker is turned on, or the power cord is plugged in the wall
indicator	outlet. (Check the primary and secondary voltage of transformer.)
Terminal	Check for power supply voltage between Q – R. (Refer to the name
	plate.) (Check the primary and secondary voltage of transformer.)
block
	Check for fluctuate voltage between R – S. (DC 15 to 60V)
Fuse	Check to determine if the fuse is open.
6,3A	(Check Varistor : R109, R21)
DC 5V	Check for voltage at the pink lead of the infrared rays receive parts.
	(Check the transformer and the rated voltage power supply circuit.)
DC 12V	Check for voltage at the QS lead of louver motor.
	(Check the transformer and the rated voltage power supply circuit.)
DC 35V	Check for voltage at the CN10 connector side point.
	(Check the transformer and the rated voltage power supply circuit.)
For detailed diagnostic procedure, refer to the service data.
