The regulator can alternatively be operated with external or internal set point.
External setpoints to be used always have to be routed to analog input 4.
In case of using a 4-20 mA signal as external setpoint, this signal can be moni-
tored for cable breaks and short circuits. If errors should occur the OCM Pro is
going to access the internal setpoint (
à
in case of using external 4-20 mA set-
points and error monitoring always set the internal setpoint additionally!).
The following equation applies for the internal calculation of the slide valve con-
trol time:
control time = (setpoint – flow
actual value
) • P_factor •
max. slide valve runtime
max. flow
