(l)The following is an example for totalizer flow counts output in which the totalizer is reset with an
external signal (when preset output status level hold mode is set (contact ON)).

* When the Reset/Start signal is in H level (DI counter control signal level: H), the totalizer
is reset to zero and stops counting. When the Reset/Start signal goes to L level, the
totalizer starts counting. The preset point output goes ON when the totalizer counts
reaches the preset point, and the output goes OFF when the totalizer is reset to zero.
(2)The following is an example for totalizer flow counts output in which the totalizer is reset with an
external signal (when one-shot pulse output mode is set).

* When the Reset/Start signal is in L level (DI counter control signal level: L), the totalizer is
reset to zero and stops counting. When the Reset/Start signal goes to H level, the totalizer
starts counting.
The preset point output goes ON when the totalizer counts reaches the preset point. The
output goes OFF when the totalizer is reset to zero or when it takes the time set pulse
