SIMPLE CHECK POINTS FOR DIAGNOSING FAULTS

Check	Diagnosis result
items
	TERMINAL BLOCK
1	There is no supply voltage	Power supply and connecting
	(AC220V) between L - N , 1 - 2	cable check
	There is no voltage (DC15 to 25V) 2 - 3
	FUSE
2	T25A 250V to fuse (F01) blown	Converter module (DB01) and
		electrolytic capacitor (C12 to C14) check
	T3.15A 250V to fuse (F04) blown	IGBT module (Q200) check
		Fan motor check
3	ELECTROLYTIC CAPACITOR VOLTAGE (C12, C13, C14)
	DC320V not available between	T25A fuse (F01) check
	+ – terminal of electrolytic capacitor	P.C. board and converter
		module (DB01) check
	INVERTER OUTPUT (Inverter and compressor connector out of position)
4	(Please confirm within six minutes after instructing in the drive.)
	Voltage between each line of inverter side	IGBT module and
	connector pins are not equal.	P.C. board check
