Feedback Superv.
These parameters define the range within which the PID Feedback signal value is supposed to stay
in a normal situation. If the PID Feedback signal goes above or below the defined supervision range
for longer time than what is defined as the
, a PID Supervision fault (F101) will be triggered.

Upper and lower limits around the reference are set. When the actual value goes above or below
these a counter starts counting up towards the Delay (P3.13.6.4). 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 with parameter P3.13.6.5) is generat-
