ERROR CODES FOR THE POWERWAVE
The following is a list of possible error codes that the Power Wave AC/DC can output via the status light (see "Troubleshooting the Power Wave / Power Feed System Using the Status LED").
| Error Code # | Indication |
|
|
|
|
|
31 | Primary overcurrent error. | Excessive Primary current present. May be related to a switch board or |
|
|
| output rectifier failure. |
|
|
|
|
|
32 | Capacitor "A" under voltage |
|
|
| (Left side facing machine) | Low voltage on the main capacitors. May be caused by improper input |
|
|
| configuration, or an open/short circuit in the primary side of the |
|
|
|
| |
33 | Capacitor "B" under voltage | machine. |
|
(Right side facing machine) |
|
| |
|
|
|
|
34 | Capacitor "A" over voltage |
|
|
(Left side facing machine) | Excess voltage on the main capacitors. May be caused by improper |
| |
|
| input configuration, , excessive line voltage, or improper capacitor bal- |
|
|
|
| |
35 | Capacitor "B" over voltage | ance (see Error 43) |
|
(Right side facing machine) |
|
| |
|
|
|
|
|
| Indicates over temperature. Usually accompanied by Thermal LED. |
|
36 | Thermal error | Check fan operation. Be sure process does not exceed duty cycle limit |
|
|
| of the machine. |
|
|
|
|
|
37 | Softstart error | Capacitor precharge failed. Usually accompanied by codes |
|
|
|
|
|
|
| The secondary (weld) current limit has been exceeded. When this |
|
41 | Secondary overcurrent error | occurs the machine output will phase back to 100 amps, typically result- |
|
|
| ing in a condition refered to as "noodle welding" |
|
|
| NOTE: For the PowerWave AC/DC the secondary limit is 500 |
|
|
|
|
|
|
| The maximum voltage difference between the main capacitors has |
|
43 | Capacitor delta error | been exceeded. May be accompanied by errors |
|
|
| by an open or short in the primary or secondary circuit(s). |
|
|
|
|
|
49 | Single phase error | Indicates machine is running on single phase input power. Usually |
|
|
| caused by the loss of the middle leg (L2). |
|
|
|
|
|
|
| Error codes that contain three or four digits are defined as fatal errors. |
|
Other | 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.
