Grounding Lead Protector
The frame of the Synergic 7 wire feeder is grounded to the frame of the power source by a lead in the con- trol cable. An overload protector prevents welding current from damaging this lead if the electrode circuit touches the wire feeder frame while the electrode is electrically hot.
If such a grounding lead fault occurs, the wire feeder display will show "GLP", and the trigger circuit will be disabled. To reset the circuit, release the trigger, make sure that the electrode is not touching the wire feeder frame, and then either press any key on the keypad or close the trigger. When the GLP circuit is reset, the "GLP" display is removed and the wire feed- er is returned to normal operating mode.
Explanation of Prompting and
Error Messages
Display | Prompt or Error |
HI | Indicates arc voltage is above 80V DC. |
---Indicates selected
HXX | Indicates wire feed overload. XX indicates |
| time remaining in seconds before unit resets |
| automatically. See sections on Routine |
| Maintenance, Periodic Maintenance, and |
| Troubleshooting Guide Problem 24. |
EP | Indicates problem in EPROM assembly. See |
| Troubleshooting Guide Problem 24. |
uP | Indicates problem in microprocessor RAM. |
| See Troubleshooting Guide Problem 24. |
EXX | Indicates various system problems. XX will |
| be a number from 01 to 10. Turn off power to |
| feeder. Wait 5 seconds. Turn power back on. |
| If error persists, see Troubleshooting Guide |
| Problem 24. If error does not reoccur, be |
| sure to check all wire feed speed, accelera- |
| tion, and timer settings before you proceed. |
Er | EEPROM error. Usually occurs at |
| Indicates one or more of the recalled settings |
| is out of acceptable limits. Press any key to |
| return to normal operation. Be sure to check |
| all wire feed speed, acceleration, and timer |
| settings before you proceed. |
GLP | Indicates that the Grounding Lead Protector |
| circuit was activated due to excessive current |
| flow into the wire feeder frame. When the |
| Grounding Lead Protector circuit is activated |
| the wire feeder is disabled, i.e. the trigger out- |
| put to the power source is opened up, the |
| motor is stopped, and the gas solenoid is |
| turned off. To resume normal operation, |
| release the trigger, make sure that the elec- |
| trode is not touching the wire feeder frame, |
| and then either press a key on the keypad or |
| close the trigger. See Problem 24 in the |
| Troubleshooting Guide. |
