ULTRA-CUT 400
4.07 Power Supply Status Codes
On start-up and during operation, the power supply control circuitry performs various tests. If the circuitry detects
a condition requiring operator attention, the status indicator on the control panel flashes a 2-part code to indicate
a code group and then a particular condition within the group. After 4 seconds, the sequence repeats.
Example: Indicator flashes 4 times; the condition is in group 4. After a 1.2 second delay, the indicator blinks 3
times; the condition code is 4-3, indicating that the coolant is overheating. After a 4-second delay, the indicator
repeats the sequence until the condition is corrected.
Some conditions can be active indefinitely, while others are momentary. The power supply latches momentary
conditions; some momentary conditions can shut down the system. The indicator may show multiple conditions
in sequence; it is important to recognize all possible conditions that may be displayed.
NOTE
These codes are for systems with Firmware versions 2.4 or later. If your system’s Firmware is a prior
version, contact your distributor for updates.

1-1
Plasma Disabled or Missing
AC Input Phase
Plasma Enable Off ; External E-Stop Activated or CCM TB1-1&2 jumper miss-
ing; Missing AC Phase; No power to GCM 2000 or 2010 Gas Control, check
GCM control cable connected, reset CP4 or CP5 circuit breaker in power supply,
blown fuse F19 in GCM.
1-2 Pilot Ignition Failure
Pilot did not start within 15 seconds. Preflow pressure too high; Defec-
tive Arc Starter
1-3 Lost Pilot
Pilot went out while CNC Start active Ensure process loaded agrees with torch
parts installed; If custom process cut current too low or preflow pressure too
high. Torch consumable parts worn
1-4 Transfer Lost
Arc was transferred to work for more than 50 ms and then went out while CNC
Start still active. Standoff too high; Current set too low.
1-5 Off the Plate Function not currently enabled
1-6 Pilot Timed out no Transfer
Must transfer from Pilot to Cutting Arc in 85 ms. (SW8-1 OFF) or 3 sec. (SW8-
1 ON). Standoff too high or void in work under torch; cut current too low for
consumables; Preflow pressure too low.
1-7 Reserved No information available; Contact customer service
1-8 Possible Shorted Torch
Tip voltage too close to electrode voltage. Plasma supply pressure too low;
Leak in Plasma hose to torch; plasma pressure / flow may be too low or cut cur-
rent too high. Torch consumable parts worn; Shorted torch body
