ULTRA-CUT 400
4.11 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 momen-
tary 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.
CCM Status Code

Plasma Disabled or
Missing AC Input
Phase
Plasma Enable Off ; External Disable / E-Stop Activated or CCM TB1-
1&2 jumper missing; Control cable to DMC not connected; Missing AC
Phase.
1-2 Pilot Ignition Failure
Pilot did not start within 15 seconds. Ensure process loaded agrees
with torch parts installed; Torch consumable parts worn; Defective Arc
Starter. Defective chopper (100-300A unit); Defective #2 inverter (400A
unit).
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; Ensure process loaded
agrees with torch parts installed; If custom process current set too low
or wrong plasma pressure.
1-5 Off the Plate Function not currently enabled
1-6
Pilot Timeout, 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; Wrong cut
process selected resulting in: Pilot 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; Ensure process loaded agrees
with torch parts installed; If custom process, plasma pressure may be
too low or cut current too high. Torch consumable parts worn; Shorted
torch body
