Fig. 23-17 Sensor settings
>Sensor type< Select between wedge or pipe sensor.
Default setting: wedge sensor
>Install. direc-
tion< Default setting: positive
This parameter should not be modified. It is going to be used only for
special applications where the flow velocity sensor is heading
up-
stream (unlike heading downstream towards the flow direction as in

This is the only case which requires setting “negative” here.
23.4 Parameter Menu “Digital Inputs”
Fig. 23-18 Digital inputs – submenu
Select from digital inputs 1…4 using the >left< or >right< arrow keys as long as the regulator
function is active. This section enables to set and the digital input signals “switch OPEN”,
“switch CLOSE” and “torque close”.
The OCM F requires these inputs for regulator operation.
The function >Stop v-measurement< is exclusively available for digital input 4.
Fig. 23-19 Digital inputs functions
>Function< One certain function is assigned to each digital input.
Choose from:
-
“Not active” - the digital input has no function
-
DI1 – “torque close” - the torque switch for the closed condition is
