FAULT CODES
Fault log
All faults that occur when using the welding equipment are documented as error messages
in the fault log: up to 99 error messages can be saved. When 99 messages have been
saved, the oldest message will automatically erase when the next fault occurs.
Only the most recent fault message is displayed on the control panel. To read the entire
fault log, the machine must be connected to the ESAT: see service aid o n page 13.
Faults are monitored/detected in two ways: by test routines that are run on initiation and by
functions that can detect a fault when it occurs.
The control panel displays a unit number to indicate which unit has generated the fault.
Fault indication on the M2 control panel
The M2 control panel has no text or symbol display, and so faults are indicated by an LED.
The LED is extinguished if there are no faults, but either flashes or lights steadily to indicate
a fault. See the specification of fault codes on page 10 for a detailed description of the
various fault codes.
The LED flashes for the following faults:

The LED lights / flashes as long as the fault is present, it can only be reset if the fault is
repaired and the machine is restarted.
