Lastly, if SUCCESSIVE, CHAIN and OFF TIME are
programmed 0, all valve outputs will be turned off and the
sequence will end. Only if OFF TIME is set to 0 will the
WELD COMPLETE output be energized for its programmed
number of line cycles. If a new pilot is received before the
WELD COMPLETE output time is over, it will be truncated.
The control will NOT sequence again unless the pilot input is
removed and re-applied. If the pilot is still applied, "PIL" will
be displayed. If OFF is programmed non-zero and the pilot
signal is still applied, the control will turn off the valve, wait
the programmed number of cycles, then repeat the sequence
starting at the Squeeze instruction of the schedule applied. In
repeat mode, the WELD COMPLETE instruction will never
be outputted.
