Minimum: Maximum:
1.0 10.0
The manipulated variable setpoint is limited in the positive and negative direc-
tions to the value set in MD 5475 before the D/A conversion. An identical value
is set for both limits. A ZK3 message (can be interrogated via PLC) is activated
when the limitation is violated.
Minimum: Maximum:
0 1
The voltage output (manipulated variable) can be inverted in machine data MD
5476 in order to compensate for differences in sign in the piping or wiring. Alter-
natively, the wiring of the manipulated variable for the valve could be altered.
Definition of direction: See Section 3.9.1.
