Troubleshooting (General)
In many cases where the cause may be listed as a cable or wire disconnected but also includes loose or broken.
All Ribbon cables have an extra receptacle near one end for measuring signals on the cable.
A number of the measurements will require probing of some small connectors or measuring signal on ribbon cables.
For probing the small connectors, standard meter probes are usually too big. We suggest making a couple probes
using steel wire. Copper buss wire isn’t stiff enough. A paper clip is a little too big. One idea is take a socket from
an Amp mate-n-loc or similar connector into which your meter probe will fit and crimp a small piece of steel wire,
(0.020 to 0.025” dia.; (0.5-0.6 mm) works best), into where wire would normally be crimped. The wire should be
soldered and crimped. The steel wire may be found in hobby stores that cater to model building.

Insulate all but the end of the wire and slide these onto your meter probe. If your meter has alligator clip adaptors
you could hold the wire in these as well, be sure they don’t short together.
Problems that do not set Status or Fault codes:
1. At power on GAS LED blinks continuously, no code set. Real problem is no or low coolant flow but it takes
4 minutes before code is set and people don’t wait that long.
Power Supply Status Codes
Group 1, Process Codes
101 Plasma Enable Is Disabled
Code 101 is activated by either an open circuit between TB1-1 & 2 on CCM I/O PCB or Plasma Enable switched
off on the GCM �010 or on the TSC 3000. TB1-1 & � comes from the factory with a jumper installed. An installer
may remove the jumper and connect a separate Plasma Enable switch or use the Plasma Enable wires included
in the 37 pin CNC cable used with the Ultra-Cut XT & Auto-Cut 300XT. The Auto-Cut 200XT and PAK 200i
which uses a 14 pin CNC does not have the Plasma Enable in the cable but an external Plasma Enable SW can be
wired to TB1-1&�.. These may be used to connect to the cutting table E-Stop switch. In either case the jumper
would be removed from TB1-1 & 2. 101 is not a latched code, it clears as soon as the condition is fixed. External
Plasma Enable is not generally used with a hand torch (Pak unit) but can be wired to TB1 same as for AC �00 XT.
Causes for 101 code other than one of the Enable switches being off (see detailed descriptions below):
• Gas Control Cable from J55 to gas control not connected.
• Ribbon cable from Relay board to I/O board not connected.
• CNC cable not connected (if using a Plasma Enable switch or output from the cutting table or robot).
• Defective Relay PCB
• Defective CCM I/O PCB
Special case: Display alternates between E101 and ----. This happens when there is both a missing phase and
Plasma enable is off. It is probably a bug in the code, it should be showing E101 & E�01 (missing phase code).
We will likely fix this in a later code release but be aware of it for now.
