8.2.19 Feedback Superv.
P3.13.6.1 Enable 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 Delay, a PID
Supervision fault (F101) will be triggered.

Process supervision
Pos. Description
1 Upper limit (ID736)
2 Lower limit (ID758)
3 Actual value
4 Reference
5 Delay (ID737)
6 Regulating mode
7 Alarm or fault
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 generated.
