ESAB AristoFeed 30 4 Series Service Manual page 30

Code Description
12 Communication error (warning)
The load on the system CAN bus is temporarily too high.
Action: Check the equipment to ensure that only one wire feed unit and/or remote control
unit are connected. See also sections 13AP1:8 and 13AP1:18 'The CAN bus' on pages 16
and 22.
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. See also sections
13AP1:8 and 13AP1:18 'The CAN bus' on pages 16 and 22.
22 Transmitter buffer overflow
The control board 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 board is unable to process information from the other units at a sufficiently high
speed. This fault is caused by abnormal loading of the microprocessor.
Action: Turn off the mains power supply to reset the unit.
27 Out of wire
The wire feed unit is not feeding any wire. The current welding process will be stopped, and
cannot be restarted.
Action: Load new wire.
At present, wire monitoring is fitted only to special versions of wire feed units.
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.
32 No gas flow
Gas flow is too low.
Action: Check the gas valve, hoses and connectors.
Gas monitoring is fitted only to special versions of wire feed units.
