Limitations
If the switch, NotOff, is selected, the welding positive lead secondary contact
(break box) remains open at the end of the search. If this switch is selected directly
before a welding instruction, welding current will not reach the torch and an Arc
Ignition Error will occur.

Fault 1
If an error occurs when activating the SmarTac board, a menu will appear with the
following prompts:
Activation of the SmarTac failed
Tries to search again with start point moved 50%RETRY
Continues the program with default search resultRETURN
Sends error to calling routine.RAISE
When RETRY is selected the start point of the search is shifted farther from the
part feature. This may give a good search result in cases where the part feature is
unusually close and the torch is touching the part feature at the beginning of a
normal search.
When RETURN is selected a default search result is used which will include any
preoffset included in the search instruction. A message will be logged in the event
log.
