ERROR CODES FOR THE POWERWAVE

The following is a list of possible error codes that the Power Wave 455M can output via the status light (see "Troubleshooting the Power Wave / Power Feed System Using the Status LED." If connected to a PF-10/11 these error codes will generally be accompanied by an "Err 006" or "Err 100" on the user interface display.

	Error Code #	Indication
11	CAN communication bus off.	Probably due to excessive number of communication errors.
12	User Interface time out error.	UI is no longer responding to the Power Source. The most likely
		cause is a fault/bad connection in the communication leads or con-
		trol cable.
21	Unprogrammed Weld Mode.	Contact the Service Department for instructions on reloading the
		Welding Software.
22	Empty Weld Table.	Contact the Service Department for instructions on reloading the
		Welding Software.
23	Weld Table checksum error.	Contact the Service Department for instructions on reloading the
		Welding Software.
31	Primary overcurrent error.	Excessive Primary current present. May be related to a short in the
		main transformer or output rectifier.
32	Capacitor "A" under voltage	Low voltage on the main capacitors. May be caused by improper
	(Left side facing machine)	input configuration.
33	Capacitor "B" under voltage	When accompanied by an overvoltage error on the same side, it
	(Right side facing machine)	indicates no capacitor voltage present on that side, and is usually
		the result of an open or short in the primary side of the machine.
34	Capacitor "A" over voltage	Excess voltage on the main capacitors. May be caused by improp-
	(Left side facing machine)	er input configuration.
35	Capacitor "B" over voltage	When accompanied by an under voltage error on the same side, it
		indicates no capacitor voltage present on that side, and is usually
	(Right side facing machine)
		the result of an open or short in the primary side of the machine.
36	Thermal error	Indicates over temperature. Usually accompanied by Thermal LED.
		Check fan operation. Be sure process does not exceed duty cycle
		limit of the machine.
37	Soft start error	Capacitor precharge failed. Usually accompanied by codes 32-35.
41	Secondary overcurrent error	The secondary (weld) current limit has been exceeded. When this
		occurs the machine output will phase back to 100 amps, typically
		resulting in a condition referred to as "noodle welding"
		NOTE: The secondary limit is 570 amps for the standard stud, and
		325 amps for all single phase operation.
43	Capacitor delta error	The maximum voltage difference between the main capacitors has
		been exceeded. May be accompanied by errors 32-35.
49	Single phase error	Indicates machine is running on single phase input power. Usually
		caused by the loss of the middle leg (L2).
Other		Error codes that contain three or four digits are defined as fatal
		errors. These codes generally indicate internal errors on the PS
		Control Board. If cycling the input power on the machine does not
		clear the error, try reloading the operating system. If this fails,
		replace the control board.

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.
