3-6 Invalid Current Control level from Gas Control
Whe ncCM requests the output current setting Gas Control it returned a value
outside the range available from the power supply. Most likely cause is a firmware
incompatibility problem. Consult factory for latest firmware update.
3-7 Gas Control returns wrong command sequence.
Firmware incompatibility. Consult factory for latest firmware update.
3-8 Mismatch between the CCM and gas control type.
One is for Autocut while the other is an Ultracut.
• The GCM 2000 and GCM 2010 use the same main PCB. For the GCM 2000
there is a jumper between
J10-4 and J802-2
which configures the program for
the GCM 2000. If that jumper is missing you will get the 3-8 code even
though both Gas Control and CCM are for Autocut.
3-9
Gas Control Communication reply fault.
Rely doesn’t match what was requested. Firmware incompatibility. Consult
factory for latest firmware update.
3-10
Warning -- Gas Control Firmware (the program) is not up to same level as
the CCM. System will work but may not be optimized for consumable best
consumable life.
Consult factory for latest firmware update.
