102 Pilot Ignition Failure
Code 102 is activated when there is no pilot current after 15 seconds of firing the Arc Starter. Pilot ignition
requires the Pilot board to be enabled, pilot switch (IGBT) turned on and high voltage pulses (HF) from the arc
Starter (either the Remote Arc Starter RAS 1000 XT or GCM 1000 XT or the arc starter built in to the AC 200 XT)
applied between the tip and the electrode of the torch.
Possible Causes for 102 code:
XT Automation Torch ONLY:
• No HF to the torch due to broken pilot wire connection in the torch leads.
• No HF to the torch due to defective Arc Starter.
• Arc Starter not receiving power.
XT Torch or 1Torch option:
• Pilot board not enabled.
• Pilot board defective.
• Relay board defective.
• Work lead current sensor defective.
• CCM defective.
• W4, tip isolation contactor, not energized for automation cutting, refer to 700 code group.
1Torch ONLY:
• W5, 1Torch Isolation Contactor, not energized for 1Torch cutting, refer to 700 code group.
Troubleshooting:
1. Determine if the problem is a lack of HF (Arc Starter) or if it’s due to the pilot circuit.
Auto-cut XT Arc Starter (inside main chassis for AC200 XT; in the GCM1000XT for AC300XT) has open spark
gap. If the spark gap is firing it is receiving power. A few early Ultra-Cut XT units were shipped with the
RAS1000 Arc Starter. Troubleshoot them the same as the GCM1000XT below. Most Ultra-Cut XT units now use
the RAS1000XT Arc Starter which doesn’t use a spark gap and is covered in the next section.
