Input/Output signal time 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 point output goes ON when the totalizer counts reaches the preset point, and the output
goes OFF when the totalizer is reset to zero.
