ULTRA-CUT 400
CCM Status Code
Code Message Remedy / Comments
Group 2 -- Plasma Power Supply
2-1 Missing AC Phase Blown fuse, Broken or loose connection on power cable
2-2 Wrong input voltage Inverter(s) not configured correctly for input voltage;
Poor power quality (brownouts, dropouts); Input power capacity / wiring too small causing
voltage drop; broken or loose power cable connections.
2-3 Inverter Over Tempera-
ture
Ambient above 40 deg C. (104 F); Blocked airflow.Failed fan; Defective inverter.
2-4 Power Supply not Ready Defective inverter; PCB4; PCB7; defective input contactor.
2-5 DC Output Low Less than 60 VDC; Defective inverter, shorted output; CCM voltage sense (J6) wire open or
disconnected. Negative lead short to gnd. Shorted chopper (100-300A only).
2-6 Inverter input fault Capacitor bank voltage imbalance (400-460-600V only) or inverter primary switching circuit
overcurrent. If occasional may be line voltage surge; remove power to reset. If persists
defective inverter; LED on inverter indicate which one.
2-7 Unexpected current Current above 20A in work or pilot leads before pilot ignition; Possible shorted torch; Defec-
tive current sensor.
2-8 Unexpected current in
pilot circuit
Current above 5A in pilot circuit; wrong or mismatched consumables; Pilot lead shorted to
negative in torch tube; Possible shorted torch
2-9 Unexpected current in
work lead
Current above 5A in work lead; Short to chassis in RAS; Negative lead short to ground.
2-10 Output Current Too High Current greater than 20% above process setting. Measure current of each inverter, only one
high likely defective inverter. All high likely defective PCB5, CCM.
2-11 Output Current Too Low Current more than 20% below process setting. Measure current of each inverter, only one
low likely defective inverter. All low likely defective PCB5, CCM.
Group 3 -- Gas Controller Status & Protocol
3-1 Gas Control Communi-
cation fault.
Cannot establish Communication with gas control. DMC to DPC Control Cable not con-
nected or Fiber-optic cable not properly connected, dirty or defective; DPC power supply or
Control PCB defective. DMC Control PCB defective; CCM defective, replace.
3-2 Gas Control reply fault. Connection was established but Gas Control did not reply to the CCM in the allowed time
(15 ms.). Dirt on fiber ends or in connectors, blow out with clean dry air. Fiber not locked
into connector; sharp bends in fiber; fiber defective. If it’s determined the fiber is OK then
DPC or DMC Control or Power Supply PCB likely defective, replace board.
3-3 Gas Supply Pressure out
of range.
DPC has detected a pressure error, Check DPC status indicator for specific problem.
3-4 Gas Control Purging The time to purge depends on Lead Length, previous fluids used, and current process fluids
selected. Wait until finished.
3-5 Gas Control Protocol
Error
Verify Firmware revison for compatiblity with DMC and DPC
3-6 Reserved No information available; Contact customer service
3-7 Gas Control sequencing
error
Verify Firmware revison for compatiblity with DMC and DPC
3-8 Gas Control Type Mis-
match
CCM must be Ultracut type with USB for use with Auto Gas Control (DFC-3000)
3-9 Gas Control Command
fault
Verify Firmware revison for compatiblity with DMC and DPC; Elctromagentic interference
with Arc Starter; inspect grounding; bonding; and isolation
3-10 DPC-fault Check DPC status indicator for specific problem
3-11 DPC valve control fault Check DPC status indicator for specific problem
3-12 DMC fault Check DMC status indicator for specific problem
3-13 Gas Controller not Con-
figured.
DMC and / or DPC not configured for a process or locked. Load process from TSC 3000 or
CNC. Check DMC & DPC status.
