ERROR CODES FOR THE POWER WAVE
®
The following is a partial list of possible error codes for the POWER WAVE ® C300. For a complete listing consult
the Service Manual for this machine.
Error Code #
36 Thermal error
54 Secondary (Output) over current error
56 Chopper communication error
58 Primary Fault error
Other
81 Motor Overload
82 Motor Overcurrent
Indication
Indicates over temperature. Usually accompanied by Thermal LED.
Check fan operation. Be sure process does not exceed duty cycle
limit of the machine
The long term average secondary (weld) current limit has been
exceeded. NOTE: The long term average secondary current limit is
325 amps.
Indicates communication link between main control board and
chopper has errors. If cycling the input power on the machine does
not clear the error, contact the Service Department.
Review error code from input board status light or status beeper.
Most likely caused by an over power condition which caused an
under voltage on the primary bus. If cycling the input power on the
machine does not clear the error, contact the Service Department.
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.
Long term average motor current limit has been exceeded.
Typically indicates mechanical overload of system. If problem con-
tinues consider higher torque gear ratio (lower speed range).
Absolute maximum motor current level has been exceeded. This is
a short term average to protect drive circuitry.
