Code Parameter Min Max Unit Default ID Description

P3.13.4.2 Upper limit Varies Varies Varies Varies 1660
Process supervision is
used to supervise that the
actual value stays within
some predefined limits. With
this function we can e.g.
detect a major pipe burst and
stop unnecessary flooding.
An upper and lower limit for
the supervision range can be
set, including a delay when
trigging faults.
