Time-based function => reset the output status, triggering if limit exceeded again
Safety instructions:

For time-based functions, e.g. monitoring of the timing of complementary input signals,
the output status is reset and a state defined as erroneous only detected if the (time)
limit is exceeded again.

To protect against incorrect usage, e.g. repeated triggering of the reset function to
bypass an alarm state, if necessary applicative measures must be taken in the PLC
programming.
