Linearisation The analog input span can be defined here. Additionally it is possible to modify
the weighting of the analog input by means of a 16-digit (max.) breakpoint table.
If used properly, this point will open up some helpful special options regarding
the setting of OCM Pro parameters. For example it is possible to convert a
level/height signal into a volume-proportional signal which can be saved or route
this signal to one of the analog outputs for further processing or display
purposes.
Just enter the number of breakpoints.
Confirm entry!
A table with the respective units will come up subsequently.
Fig. 9-66 Table of values for analog input span
Enter the mA value in the X-column and the other value in the Y-column (appro-
priate unit has been selected before under "Units“).
In case of classic applications such as setpoint input or in order to save a meas-
urement value just enter "2“ as breakpoint value. Subsequently define the ana-
log input span, i.e. enter the respective values for 4 mA and 20 mA.
Offset In addition to the input current, a fixed positive or negative offset using the unit
chosen before can be added to the analog value.

Fig. 9-67 Digital inputs – submenu
This section enables to set and to assign the digital input signals „Control
OPEN“, „Control CLOSED“ and „Torque CLOSED“. The OCM Pro CF,
type >M4< requires these inputs for regulator operation.
The function >Lock v-measurement< is exclusively available for digital input 1.
