REMOTE CONTROLS
A number of remote control units can be connected to the power source, these are
described in a separate service manual with filename 0740 800 170.
FAULT CODES
Fault codes are used in order to indicate and identify a fault in the equipment.
Fault log
All faults that occur when using the welding equipment are documented as error messages
in the fault log. When the fault log is full, 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 tools on page 37.
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. The
following unit numbers are used:
U0
= welding data unit
U2
= power source
U4
= remote control unit
