Tweco 400 XT Ultra-Cut Plasma Cutting System With Automated Gas Control - Manual (Page 193)

ULTRA-CUT 400 XT
Manual 0-5306 APPENDIX A-69
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. At-
tempting 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 firmware 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 communica-
tions 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.
From the bypass valve in most systems coolant is plumbed to the rear panel coolant supply fitting where it goes to the torch
via the RAS 1000 XT, the remote arc starter, The UC 400 XT had an additional external heat exchanger, the HE 400XT in the
supply line between the power supply and the remote arc starter. In the AC 200 XT with built in arc starter coolant goes to the
water cooled HF (high frequency) coil and then to the torch supply lead attached to the internal torch connection bulkhead.
Coolant from the Torch returns to the RAS and on to the return fitting on the rear of the power supply. For the AC 200 XT
return is to the torch bulkhead built in to the unit. Coolant returning from the torch is routed through the rear panel filter
then through the radiator (internal heat exchanger) and through the flow switch. Ultra-Cut models also have a flow sensor in
series the flow switch that can detect bubbles in the coolant. Upon leaving the radiator, coolant goes into the bottom inverter
“cold plate” or liquid cooled heat sink. It flows through the inverters in series and returns to the tank. detect bubbles in the
coolant. Upon leaving the radiator, coolant goes into the bottom inverter “cold plate” or liquid cooled heat sink. It flows
through the inverters in series and returns to the tank.
401 Coolant Level Low
The coolant reservoir (tank) has a normally open (tank dry) float type level switch, LS1. When the coolant level in the tank
is below about ½ full this fault will signal the need to add coolant. It will not stop the process during a cut but will instead
show the 405 fault as a warning. As soon as the cut stops it will not allow another to start until the issue is corrected.
