Run signal for the timer. The timer runs when this input is
active and holds when this input is inactive.
Transmitter - - - - Digital Active whenever the time is greater than zero
Note:
The elapsed time is not retained through a power loss; it is set to zero upon power up.
Function
To trigger the output by setting the time, to have the timer count down while the input is ac-
tive, and have the output active until the time runs out, set Function to One Shot.
Time
Set the amount of time to count down. While the input is active this parameter counts down
until it reaches zero. The output is active whenever this parameter is greater than zero.
