Timing starts when the start signal goes ON, and is
reset when the start signal goes OFF.
While the start signal is ON, the timer starts when the
power comes ON or when the reset input goes OFF.
The control output is controlled using a sustained or
one-shot time period.
*Output is instantaneous when setting is 0.

Output Timing starts when the start signal goes ON.
The status of the control output is reversed when time
is up (OFF at start).
While the start signal is ON, the timer starts when the
power comes ON or when the reset input goes OFF.
* Normal output operation will not be possible if the
set time is too short.
Set the value to at least 100 ms (contact output
type).
** Start signal input is disabled during timing.
