Pickup delay : The timer channel starts the delay time when the source changes to
the active state ( High level or Low level trigger). At the end of the delay time, the
timer output switches into an active state ("On") so long as the source retains the
active state. If source's active state is shorter than the delay time, no reaction
takes place with the timer output.
Dropout delay : The output of the timer channel becomes active ("On") when the
source switches to an active state ( High level or Low level trigger ) or edge trig-
gering ( Rising edge , Falling edge or Edges (both) triggers). The same edge or the
switch of the source from active back to inactive starts the delay time. At the end of
the delay time, the timer's output becomes active ("Off").
The image shows the signal of a dropout delay with level triggering (Low level).
Retriggerable : This option enables a restart of the delay time via other source trig-
ger events during the delay time.
Source : Specify the delay channel here and which level or which edge is to be
delayed.
