0-5/10 V can be set by NIVUS service personnel only.
-
set point input linearisation (normally >2< is going to be entered as number
of breakpoints. Set the setpoint start (=0) to 0/4-20 mA and the setpoint stop
to 20 mA subsequently. The input area can be linearised as well.)
Offset:
-
this values is going to be added to the external setpoint. Negative values are
allowed to be set as well.
Cable break monitoring is being executed if the external setpoint has been set to
