Sensor output delay

When there is a detected change in process conditions, from wet-to-dry or
dry-to-wet, the Sensor Output Delay variable can action a delay of up to 3600 seconds
before the new state change is indicated. The default delay is one second.
Depending on the application, a suitable delay can prevent constant switching of the
output state. If, for example, there are waves in a tank, then there may be splashes causing
intermittently detected changes in process conditions. The sensor output delay ensures
that the fork is dry or wet for a suitable period before switching.
