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.
