Upper and lower limits around the reference are set. When the actual value goes above or below, a counter
starts counting up towards the Delay (P3.12.5.4). When the actual value is within the allowed area, the same
counter counts down instead. Whenever the counter is higher than the Delay, an alarm or fault (depending on
the selected response) is generated.
