NOTE:
THE POTENTIOMETER RESISTANCE BETWEEN PINS 2 AND 3 CAN BE
MEASURED AT THE CONNECTOR. INSERT TWO SHORT LENGTHS OF
22 AWG WIRE INTO THE PIN 2 AND 3 RECEPTACLES IN THE CONNECTOR.
CLIP ON LEADS FROM A DVM (DIGITAL VOLTMETER) TO MEASURE THE
RESISTANCE.

9. Adjust the travel sensor shaft to obtain the
calculated resistance determined in step 7, $ 100
ohms.
Note
In the next step, be sure the feedback
arm surface remains flush with the end
of the travel sensor shaft.
10. While observing the resistance, tighten the screw
(key 80) to secure the feedback arm to the travel
sensor shaft. Be sure the resistance reading remains
within the range listed in step 7, $100 ohms. Paint the
screw to discourage tampering with the connection.
11. Disconnect the multimeter from the travel sensor
connector.
12. For the DVC6010 SIS only, connect the travel
sensor connector to the PWB as described in
Replacing the Module Base.
13. Travel sensor replacement is complete. Install the
digital valve controller on the actuator.
Travel Sensor Adjustment with the Field
Communicator
The next two steps do not apply if you used a
multimeter to adjust the travel sensor. Perform these
steps only if you elected to adjust the travel sensor
using the Field Communicator.
14. For the DVC6010 SIS, connect the travel sensor
connector to the PWB as described in Replacing the
Module Base.
15. For both DVC6010 SIS and DVC6015, perform
the appropriate Travel Sensor Adjust procedure in the
Calibration section.
