Operation of the timer function
The timer can be operated with the keys (start, stop, cancel, acknowledge) if the timer at opera-
ting level is indicated. Time-out is not active here. If the logic input is configured accordingly,
then a key, such as the
i
key, can be used. In this case, the timer can also be operated even if
the timer value does not appear in the display.
