Badger Meter SRD/SRI Valve Positioners - Manual (Page 49)

Decreasing Ramping
To modify the control valve dynamics, Travel Time Limits may be changed . Inputting values higher than the default (0 .4 sec)
will slow down the response .
Control Gap
Control Gap defines the sensitivity of the positioner such that no corrective action will be taken if the Control Difference is less
than the defined limit . The default is 0 .2 % .
Options Page
The Option Board page displays the options of the positioner . Only in
the workshop security level it is possible to change the option settings
and write it into the device . This factory configuration has to be done
carefully and only options which are installed in the positioner may
be selected . In all other security levels it is only possible to view the
options information .
Each option though can be activated offline, to see the capabilities and
functionality behind each option .
Position Transmitter Signal (Pos. Transmitter)
The Position Transmitter is an optional feature that can be connected
to the electronic board in the factory or retrofit . In the event that the
Option Board is retrofit, the positioner will execute an alarm indicating
and Option Board error (Diagnosis Message: Optionboard err) . In this
case the alarm needs to be confirmed and the electronic is reconfigured
to support this Option Board .
In connection with the Position Transmitter additional two channels of
this Option Board are available for the Alarm Output . This output can be
used to display alarms from the positioner in a remote distance .
The feedback signal of the Position Transmitter can be configured to Direct Acting or to Reverse Acting . Under Direct Acting the
feedback signal is increasing to the increasing valve position . Under Reverse Acting the feedback signal is increasing to the
decreasing valve position .
