Code
If GCM 1000: Control cable not connected or Basic ID signal open.
GCM 2010 & 2000: Dirt on fiber ends or in connectors, blow out with clean
dry air; fiber not locked into connector; sharp bends in fiber; fiber
defective; Gas Control PCB defective, replace. CCM defective, replace.
3-2 Gas Control Communication
reply fault, connection was
established but CCM did
receive a reply to a process
request. Gas Control did not reply to signal from CCM in allowed time. 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 problem persists Gas
Control PCB likely defective, replace board.
If GCM 1000, Plasma < 15 PSI; faulty or disconnected pressure SW.
If GCM2010_AG, GCM2000_AC or later or Gas Control has been updated
with 19X2219_AG or later PCB: Plasma or Shield input out of range 105-135
3-4 Gas Control not ready Purging; not in RUN mode; Gas Control faulty, replace PCB.
3-5 Gas Control Protocol Fault Application error or firmware compatibility fault
3-6 Invalid Current Control level
from GCM GCM sent output current level outside the range of the power supply,
Check firmware compatibility
3-7 Gas Control returns wrong
command sequence Check firmware compatibility
3-8 CCM and Gas Control type
(Autocut-Ultracut) mismatch Install correct CCM or Gas Control for system
3-9 Gas Control Communication
reply fault Reply not compatible with request; Check firmware compatibility
3-10 Warning. -- Gas Control System will function but control may not be optimized for best
4-1 Coolant Level low fault Check coolant level, add as needed.
Low coolant flow after power
on purge.
Not cutting: < 0.7 gal/min for 15
sec;
Cutting: flow between 0.35 to
0.7 gal/min for 3 sec. or
4-3 Coolant overheated (>70
deg. C, 158 deg F) Coolant fan failed; radiator fins clogged with dirt; Ambient temperature >
40 deg C.
Coolant System not ready. If new installation recycle power to restart pump, may take a few times to
fill hoses;
During power on purge /
priming, flow did not reach 0.35
gal/min for at least 5 seconds Damaged torch coolant tube; Suction leak introducing air into coolant,
suspect rear panel filter seal; clogged filter; defective pump.
While cutting detected low coolant level, does not stop cut.
Add coolant as required.
Suction leak introducing air into coolant, suspect rear panel filter seal;
clogged filter; defective pump.
