SECTION 4
All fault signals will remain on for a minimum of 10 seconds. If fault clears, all will reset automatically
except for over-current. To clear over-current, the power must be shut off for 5 seconds and then turned
f. Help Codes (See Section 6.1, Troubleshooting for Causes and Solutions):
1. Line voltage, idle +/- 15 % - line voltage has fluctuated +/- 15 %.
2. Line voltage, cutting +/- 20 % - line voltage has fluctuated +/- 20 %.
3. Control bias, +/- 15 V bias split - Control transformer supplying insuffient voltage to the control circuit.
4. Thermal switch - Switch opens due to excessive heat within the unit.
5. Pressure - Incorrect air pressure being supplied. Minimum 60 psi / maximum 95 psi.
6. Fail to fire - Arc failed to transfer to workpiece.
7. Pilot Arc timeout (~ 5 seconds) - Cutting process did not begin within the 5 second limit.
8. Torch error - Improper assembly of torch consumables.
Torch nozzle making contact with workpiece at machine power-up.
10. Feedback improper - current sensor failed.
11. Primary over-current - Converter failure.
12. Single phase operation, shutdown - Exceeded single phase duty cycle rating.
13. OCV (open circuit voltage) failure - Voltage or current not detected when test (PIP) is performed.
14. Ambient temperature - Make sure adequate air flow is around all sides of unit. Check air louvers and any other
openings to ensure that any obstruction is removed.
15. Bus charger failure - Primary bus not up to voltage.
19. Torch trigger early engagement - Torch trigger depressed at power up.
20. PIP (Parts in place) no retract - Piston did not retract when air applied.
21. PIP (Parts in place) no continuity - Piston did not drop back in place when signal to solenoid was removed.
Note:
back on.
