Tweco 150 Ultra-Cut - Manual (Page 76)

Manual No. 0-4800 4-12 OPERATION
Error
Code Error Remedy / Comments
2-1 Missing 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 or Pilot Regulator Over
Temperature
Failed fan; Ambient above 40 deg C. (104 F); Blocked airflow
2-4 Power Supply not Ready Defective inverter
2-5 DC Output Low
Output less than 60 VDC; Defective inverter, shorted output; Shorted pilot
regulator (chopper); CCM voltage sense (J6) wire open or disconnected.
2-6 Primary over current fault
Over current detected in inverter primary circuit, remove power to reset;
defective inverter; voltage surge;
2-7 Unexpected current
Current >20A in work or pilot leads before pilot ignition; Possible shorted
torch; Defective current sensor.
2-8
Unexpected current in pilot
circuit Current > 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 > 5A in work lead; Short to chassis in RAS; Negative lead short to
ground.
3-1
Gas Control Communication
fault, Cannot establish
Communication with gas
control. 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.
3-3 Gas Pressure Low
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.
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 PSI; Unplugged or Faulty pressure sensor.
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
firmware needs update System will function but control may not be optimized for best
performance / consumable life
