ALFE reports error <n>

Only for machines with an ALFE subsystem (Teach Trace Equipment).

Apart from the ALFE subsystem faults that are reported explicitly, other messages from the ALFE subsystem are displayed if the servicing mode is active. <n> is a hexadecimal number whose bits each have a different significance. Only the following bits are assigned:

xxxx xxxx xxxx xxx1

0001 RAM error.

The power-on self-test by the ALFE subsystem has discovered a memory error. The ALFE subsystem is no longer functioning reliably. LFE board is damaged.

Inform ESAB service.

xxxx xxxx xxxx xx1x

0002 ALFE system cycle time exceeded.

The ALFE subsystem is no longer functioning reliably.

Restart the control system. If the fault occurs again, inform ESAB service.

The following three errors occur in conjunction with the ATAS ASOD test system:

xxxx xxxx x1xx xxxx

0040 Overflow on ALFE interface.

Only in conjunction with an ASOD test system connected to the LFE board.

Check the interface parameters.

xxxx xxxx 1xxx xxxx

0080 Framing Error on ALFE interface.

Only in conjunction with an ASOD test system connected to the LFE board.

Check the interface parameters.

xxxx xxx1 xxxx xxxx

0100 Parity Error on ALFE interface.

Only in conjunction with an ASOD test system connected to the LFE board.

Check the interface parameters.

xxxx xx1x xxxx xxxx

0200 24-volt error.

See error (220).

xxxx x1xx xxxx xxxx

0400 15-volt error.

See error (221).

xxxx 1xxx xxxx xxxx

0800 DMA error.

See error (222).

1xxx xxxx xxxx xxxx

8000 Internal ALFE error.

The ALFE subsystem is no longer functioning reliably.

Restart the control system. If the fault occurs again, inform ESAB service.
