Input/Output Timing Chart
* 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 output goes ON when the totalizer count exceeds the preset value, and the output goes
OFF when the totalizer is reset to zero.
