7 FAULT CODES
Code Description
12 Communication error (warning)
The load on the system CAN bus is temporarily too high, or there is electric noise on
the bus.
Action: Check the equipment to ensure that only one remote control unit is
connected. See also "Service aid", page 79.
13 High temperature external
The temperature monitoring circuit has operated. The power source is stopped, and
cannot be restarted until the circuit has reset.
Fault code 13 does not normally occur at standard equipment. The sensing input is
bridged by a resistor on circuit board 18AP1, see "18AP1:3 Temperature monitoring",
page 47.
15 Lost messages
The bus CAN controller 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
"20AP1:3 The CAN bus", page 57.
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.
28 Stack overflow
The stack memory is full.
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.
