When the timer reaches the pre
set
value (100) and turns the timer bit on,
the contact for T33 turns on. Power
flow from this contact turns on the
M0.0 memory location. Because the
timer is enabled by a Normally Closed
contact for M0.0, changing the state of
M0.0 from off (0) to on (1)
resets the
timer.
