Input function command 15: OFF (OFF timer), 24: OFF2 (OFF timer 2)
When the input signal is turned OFF, the OFF command delays the timing of putting out an OFF
signal by the setting time of the OFF timer, as shown in the figure below. The timer is activated
only when it receives an OFF signal, as illustrated in the timing chart.
Specifying the timer OFF time
Set the timer OFF time with the output time data and
specify the output time setting parameter with the
input function parameter which pairs off with the
timer command function.
