ERROR CODES
The following is a partial list of possible error codes for the Power Wave AC/DC 1000. For a complete listing con- sult the Service Manual for this machine.
POWER SOURCE- WELD CONTROLLER
|
| Error Code # | Indication |
|
|
|
|
31 | Primary (Input) overcurrent error. | Excessive Primary current present. May be related to a switch board or output | |
|
|
| rectifier failure. |
|
|
|
|
32 | Capacitor "A" under voltage (Left | Low voltage on the main capacitors. May be caused by improper input configu- | |
|
| side facing machine) | ration, or an open/short circuit in the primary side of the machine. |
33Capacitor "B" under voltage (Right side facing machine)
34 | Capacitor "A" over voltage | (Left | Excess voltage on the main capacitors. May be caused by improper input con- | |
| side facing machine) |
| figuration, , excessive line voltage, or improper capacitor balance (see Error | |
|
|
| 43) |
|
35 | Capacitor "B" over voltage | (Right |
| |
|
| |||
| side facing 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 | |
|
|
| ||
41 Secondary (Output) overcurrent error | The long term average secondary (weld) current limit has been exceeded. | |||
|
|
| This error will cause the machine output to phase back to 100 amps, typi- | |
|
|
| cally resulting in a condition referred to as “noodle welding”. | |
|
|
| NOTE: The long term average secondary current limit is 1050 amps. | |
|
|
|
|
|
43 | Capacitor delta error |
| The maximum voltage difference between the main capacitors has been | |
|
|
| exceeded. May be accompanied by errors | |
|
|
| or short in the primary or secondary circuit(s). | |
|
|
| ||
46 Secondary (Output) overcurrent error | Absolute maximum output level has been exceeded. Usually associated with | |||
|
|
| excessive short circuit currents and/or specific weld mode issues. This is a | |
|
|
| short term average designed to protect the inverter switching circuitry. | |
|
|
|
|
|
49 | Single phase error |
| Indicates machine is running on single phase input power. Usually caused by | |
|
|
| the loss of the middle leg of the input power (L2). | |
54Secondary (Output) overcurrent error The long term average secondary (weld) current limit has been exceeded.
This error will immediately turn off the machine output.
Other | 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.
