Tweco 100 Ultra-Cut Plasma Cutting System with Automated Gas Control - Manual (Page 95)

ULTRA-CUT 100 XT
Manual 0-5303 OPERATION �-25
Status Indicators on the DMC & DPC modules flash a 2-part code. Both green and red flash the firmware version
at power up. Only the red flashes for a fault.
First part of the code indicates a code group, the second part a particular condition within that group. DMC and
DPM may flash codes at the same time and they may be different codes. For example, a power supply fault, such
as 1-3, in the DMC could prevent communicating with the DPM so the DPC would flash one it’s group 2 codes. You
have to consider the codes in all the modules, CCM, DMC & DPC before determining which hardware has the fault.
The 2 digit code is separated by a 1.2 second space between digits and a � second space before the sequence repeats
or flashes another code group. Codes displayed may be currently active or may represent a fault that shut the
process down but is no longer active. If the fault that shut down the process is no longer active the first blink of
the first digit is extra long.
Example: Indicator flashes 1 long followed by 3 shorter blinks the condition is in group �. After 1.2 seconds delay,
the indicator blinks 3 times; the condition code is �-3 (the first long blink counts as part of the first digit), indicat-
ing the DMC has detected a DPC time-out error and it is not currently active. After a � second delay, the indicator
repeats the sequence until the condition is corrected.
