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 2010 or on the TSC 3000. TB1-1 & 2 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 which uses a 1� pin CNC does not have the Plasma Enable
in the cable. 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.
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 & E201 (missing phase code). We will likely fix this in a
later code release but be aware of it for now.
External or CNC Plasma Enable D2, CNC PLASMA ENABLE LED, is not on.
• LED D2 on the CCM will be on if this input is satisfied either with the jumper on TB1- 1 & 2 or an external or CNC
switch. If the jumper is in place and the LED is not on, the CCM is most likely defective.
• If the jumper at CCM TB1-1 & 2 has been removed to use an external switch, install a jumper as a test. If D2 illuminates
the problem is with the switch or it’s wiring.
• If Plasma Enable is wired through the CNC cable remove the cable and jumper J15 pins 25 & 26. If D2 still not on
there may be a problem in the wiring inside the power supply.
Plasma Enable from Gas Control or TSC 3000
If the External or CNC Plasma Enable is satisfied, D2 is on, a relay K7 on the CCM I/O PCB energizes supplying +15V to
another relay K1 on the I/O board. An active low signal, /Plasma Enable-HMI, comes from TSC 3000 Plasma Enable switch
via the Relay PCB or if TSC 3000 is not installed the signal originates on the Relay PCB. This signal applies ground to the K1
relay energizing it and lighting the LED, D3 on the I/O board. K1’s contacts go back to the Relay board and the Gas control
connector J55 to allow turning on relays and solenoids on those devices. The AC 200 XT does not use the separate Gas
Control or the TSC 3000.

When the circuit between J54-1 & 3 is closed (jumper,
etc.) K7 is energized and requires a Plasma Enable SW
or equivlant to enable the plasma.
With J54-1 & 3 open K7 is denergized and it's NC
contacts complete the Plasma Enable-HMI circuit.
