Travel Sensor Adjust

(TB > Calibrate > Travel Sensor Adjust)
The travel sensor is normally adjusted at the factory
and should not require adjustment. However, if the
travel sensor has been replaced, adjust the travel
sensor by performing the appropriate procedure. See
the Maintenance section for Travel Sensor
Replacement procedures.
WARNING
During a travel sensor adjustment, the
valve may move. To avoid personal
injury and property damage caused
by the release of pressure or process
fluid, provide some temporary means
of control for the process.
