Code Description
15
Lost messages
The bus CAN circuit indicates that a message has been lost. No functions are disabled by
this fault.
Action:
Check that all units are correct connected to the CAN bus.
17
Lost contact with the wire feed unit
Current activities will be stopped: see Fault Code 18.
This fault can be caused by a break in the connection (i.e. the CAN cable) between the wire
feed unit and the control panel.
Action:
Check the CAN cables.
18
Lost contact with the power source
Current activities will be stopped and welding start is prevented.
This fault can be caused by a break in the connection (i.e. the CAN cable) between the
power source and the control panel.
It is possible, with the machine on, to break the connection between units and then to
reconnect them without problems. The control panel “knows” if it has lost contact with any
unit. When it establishes contact again, the power source is updated with all the settings
that applied before the break.
Action:
Check the CAN cables.
19
Memory error in data memory
This fault will be detected if the information in the battery--backed memory has become
corrupted.
Action:
This fault corrects itself, but stored data in the current memory section will be lost. If
the battery voltage is correct, and if the fault recurs each time the unit is started, there is a
fault in the RAM memory. Replace the welding data board, 1AP1, in the control panel.
22
Transmitter buffer overflow
The control panel is unable to transmit information to the other units at a sufficiently high
speed.
Action:
A break in the bus line can cause this fault. Check the CAN cabling. Turn off the
mains power supply to reset the unit.
23
Receiver buffer overflow
The control panel is unable to process information from the other units at a sufficiently high
speed. This fault is caused by abnormal loading of the microprocessor in the control panel.
Action:
Turn off the mains power supply to reset the unit.
26
Program operatiing fault
Something has prevented the processor from performing its normal program duties. The
program restarts automatically. The current welding process will be stopped. This fault does
not disable any functions.
This fault should never occur in reality. Contact ESAB if the fault does occur.
28
Stack overflow
The program execution does not work.
This fault should never occur in reality: the fault code is intended as an aid during
development work. Contact ESAB if the fault does occur.
31
No reply from the display unit
The microprocessor has no contact with the display board.
Action:
Check the ribbon cable and connectors between the welding data board (1AP1)
and the display board (1AP2).
