Figure 21: Error Indications
The red ERROR LED indicates abnormal conditions. The error code is displayed in the PHC 3 digit LED
display as E.XX where XX represents the error number. The meanings are listed below. Most errors are
cleared by either removing the abnormal condition or with the application of the next “Cycle Start” from the
CNC.
E.01 CYCLE_START at power up Error
Reason: The CNC CYCLE_START input was active when the PHC was powered up.
Solution: Deactivate the CYCLE_START input on the CNC interface to clear the error.
E.02 Plate Contact at Home Error
Reason: Ohmic contact sensed the work piece when the torch was at the maximum retract position.
Possible causes:
• A short circuit in either the nozzle connection wire or the torch consumables.
