Tweco 400 Ultra-Cut XT Plasma Cutting System - Manual (Page 219)

ULTRA-CUT 100 XT/200 XT/300 XT/400 XT
Manual 0-5297 APPENDIX A-85
This is the normal code when the gas control is conducting a purge at start up or when the process is loaded
or changed or when the plasma system has been disabled and is returned to “Enable”. If it is a GCM 2010 the
Mode switch may not be set to the RUN mode.
Code 304 combined with 204 & 402 when the Plasma Enable on the GCM 2010 gas control is set to disable can
indicate a fault in the CCM I/O PCB. When switching back to Enabled the pump will not restart so continues
to display 4-2 indicating no coolant flowing.
Normally the code during a disable should be 101. Circuits on the I/O PCB detect the Plasma Enable is disabled
and send signal to the microcontroller in the CCM. If a fault in the CCM prevents that signal from getting sent
to the microcontroller it doesn’t know the system is disabled so it sets these other 3 codes.
305 Gas Control Protocol Error
Application error or firmware incompatibility fault. Consult factory for latest firmware update. Possible elec-
tromagnetic interference from the Arc Starter; inspect grounding, bonding, and isolation.
306 Not Used. This is one of the reserved codes from the earlier product.
307 Gas Control returns wrong command sequence.
Firmware incompatibility. Consult factory for latest firmware update. Possible electromagnetic interference
from the Arc Starter; inspect grounding; bonding; and isolation.
308 Mismatch between the CCM and gas control type.
The Auto-Cut XT CCM is designed to work with the GCM 1000 (AC 300 XT) or the built in gas control of the AC
200 XT. Attempting to use a GCM 2010 or DFC 3000 Auto Gas Control on an Auto-Cut will result in a 308 code.
Similarly attempting to use a CCM from an Auto-Cut XT in an Ultra-Cut XT supply will also result in a 308 code.
309 Gas Control Communication reply fault.
Relay doesn’t match what was requested. Possible firmware incompatibility. Consult factory for latest firm-
ware update.
Possible electromagnetic interference from the Arc Starter; inspect grounding; bonding; and isolation.
310-313 DFC 3000 Auto Gas Faults.
These different codes displayed on the power simply indicate one of the Auto Gas modules (DPC for codes
310 or 311; DMC for 312 and 313 could be either) is reporting a fault. You need to refer to the specific modules
blinking red LED status indicator and the Status code tables for more information.
GCM 2010 Status Codes
GCM 2000 has an LED on the front panel which blinks various codes.
GCM 2010 has LCD display which displays many of the Status messages. However, there are a few relating to
communications that aren’t clear.
When there is a communication error it will be displayed but once it has recovered the display will show what
the error was by displaying:
^E4 – Low level CAN bus error where the CCM did not acknowledge receiving a message from the Gas Control.
^E5 – Low level CAN bus error where the bus is off.
^E6 – CAN bus communication (the fiber-optic) has timed out.
Group 4 codes relate to the Liquid Cooling System
Cooling system description. System includes a reservoir, a pump, one or more heat exchangers, flow switch,
level switch and flow sensor on some models. Also included are a filter and various fittings and hoses. New
coolant is installed into the reservoir or “tank” from an opening in the unit’s front panel where there is a visual
level indicator. Coolant flows to the pump inlet from the bottom of the tank, is pumped through a pressure
relief or “bypass” valve which limits MAX pressure to 150 PSI bypassing excess flow back into the reservoir.
The coolant temperature sensor, TS1, a linear NTC sensor, is mounted on the bypass valve.
