(DVC6010, DVC6020 AND DVC6030)
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.
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
at the calculated resistance determined 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, 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, connect the travel sensor
connector to the PWB as described in Replacing the
Module Base.
