I/O Functions

For details, refer to the timing charts on Data Sheet.

Inputs
*1
Start signal Normally functions to start timing.
In modes A-2 and A-3, disable timing. In mode S, starts and stops timing.
Reset Resets present value. (In elapsed time mode, the present value returns to 0; in remaining
time mode, the present value returns to the set value.)
Count inputs are not accepted and control output turns OFF while reset input is ON.
Reset indicator is lit while reset input is ON.
Gate *2 Disables timing. (If a reset occurs while the gate input is ON, a reset will be performed.)
Outputs Control output

Outputs take place according to designated operating mode when timer reaches
corresponding set value.
