ERROR CODES FOR THE POWER WAVE®

The following is a partial list of possible error codes for the POWER WAVE® i400. For a complete listing consult the Service Manual for this machine.

POWER SOURCE–––WELD CONTROLLER

	Error Code #	LECO	Indication
		(FANUC#)
31	Primary (Input) overcurrent error.	49	Excessive Primary current present. May be related to a
			switch board or output rectifier failure.
32	Capacitor “A” under voltage	50	Low voltage on the main capacitors. May be caused by
	(right side facing the Switch PC Board)		improper input configuration, or an open/short circuit in the
33	Capacitor bank "B" under voltage	51	primary side of the machine.
	(left side facing the Switch PC Board)
34	Capacitor "A" over voltage	52	Excess voltage on the main capacitors. May be caused by
	(right side facing the Switch PC Board)		improper input configuration, excessive line voltage, or
35	Capacitor "B" over voltage	53	improper capacitor balance (see Error 43)
	(left side facing the Switch PC Board)
36	Thermal error	54	Indicates over temperature. Usually accompanied by
			Thermal LED. Check fan operation. Be sure process does
			not exceed duty cycle limit of the machine.
37	Softstart (pre-charge) error	55	Capacitor precharge failed. Usually accompanied by
			codes 32 and 33.
39	Misc. hardware fault	57	Unknown glitch has occurred on the fault interrupt circuit-
			ry. Sometimes caused by primary over current fault, or
			intermittent connections in the thermostat circuit.
43	Capacitor delta error	67	The maximum voltage difference between the main capac-
			itors has been exceeded. May be accompanied by errors
			32-35. May be caused by an open or short in the primary
			or secondary circuit(s).
54	Secondary (output) over current	84	The long term average secondary (weld) current limit has
			been exceeded. This error will immediately turn off the
			machine output.
			NOTE: The long term average secondary current limit is
			450 amps.
			A complete list of error codes is available in the
			Diagnostics Utility (included on the POWER WAVE®
		see com-	Utilities and Service Navigator CDʼs or available at
Other			www.powerwavesoftware.com).
		plete
		listing	Error codes that contain three or four digits are defined as
			fatal errors. These codes generally indicate internal errors
			on the Power Source Control Board. If cycling the input
			power on the machine does not clear the error, contact the
			Service Department

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
