OPERATION 4-6 Manual 0-5057
Status Code Key for PAK 200
Status Code Message Cause/Remedy
1-1
System not Enabled or Miss-
ing AC Input Phase External E-Stop Activated or CCM TB1-1&2 jumper missing;
Missing AC Phase; GCM200 control cable not connected.
1-2 Pilot Ignition Failure
Pilot did not start within 15 seconds.
Plasma pressure too high; Defective Arc Starter
1-3 Lost Pilot
Pilot went out without shutoff signal; Plasma pressure too high;
cut current set too low for consumables.
1-4 Loss of Transfer
Arc transfer (>50 ms.) then arc lost with START still on. Standoff
too high; Current set too low.
1-5 Of the Plate Function not currently enabled.
1-6 Pilot Timed out w/o Transfer
Must transfer from Pilot to Cutting Arc in 85ms. (SW8-1 OFF) or 3
sec. (SW8-1 ON). Standoff too high or void in work under torch;
cut current too low for consumables; Plasma pressure too low.
1-7 Not used
1-8
Tip to Electrode Voltage too
low
Detected tip voltage too close to electrode voltage. Plasma fl ow/
pressure too low; Plasma leak; cut current too high; shorted
torch body; consumable parts worn out.
2-1 Missing Phase Blown fuse, Broken or loose connection on power cable
2-2 Wrong input voltage
Inverter(s) not confi gured 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 airfl ow
2-4 Power Supply not Ready Defective inverter
2-5 DC Output Low
Output less than 60VDC; Defective inverter, shorted output;
Shorted pilot regulator (chopper); CCM voltage sense (J6) wire
open or disconnected.
2-6
Inverter primary over current
or cap voltage imbalance 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 Com-
munication with gas control.
GCM 200 Control cable not connected or Basic ID signal open;
CCM not PAK 200 (SW13-1 should be OFF) or
CCM defective, replace.
3-2
Gas Control Communication
reply fault
,
Does not apply to PAK-200, if displayed CCM defective.
3-3 Gas Pressure Low Plasma < 51 PSI; faulty or disconnected pressure SW.
