	Do characteristics of elec-			No
	tronic thermal O/L relay
	and those of motor over-
	load match?

			Yes
				No
				No

Is electronic thermal O/L relay setting correct?

Yes

Load excessive?.

Yes

Reduce load or increase drive

capacity

Connect thermal O/L relay externally.

Set to correct level.

Probable faulty drive or error because of noise,

etc.. Contact GE Fuji.
