DVC6000f Series
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 DVC6010f, 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 DVC6010f, connect the travel sensor
connector to the PWB as described in Replacing the
Module Base.
15. For both the DVC6010f and the DVC6015,
10
perform the appropriate Travel Sensor Adjust
procedure in the Calibration section.
Type DVC6020f Digital Valve Controller
and Type DVC6025 Remote Feedback Unit
Refer to figure 11-4 for Type DVC6020f and 11-5 for
Type DVC6025 key number locations.
1. Insert the travel sensor assembly (key 223) into the
housing. Secure the travel sensor assembly with
screw (key 72).
If assembling a DVC6020f digital valve controller, use
step 2a. If assembling a DVC6025 remote feedback
unit, use step 2b.
2. a. Connect the travel sensor connector to the PWB
as described in Replacing the Module Base.
b. Connect the three travel sensor wires to the
terminals.
10-12
Note
For the Type DVC6025 feedback unit,
connect the potentiometer assembly
(key 223) wires to the terminals as
follows:
red
" terminal 1
white " terminal 2
black " terminal 3.
3. Loosely assemble the screw (key 80), plain washer
(key 163), and nut (key 81) to the arm assembly (key
91), if not already installed.
4. Attach the arm assembly (key 91) to the travel
sensor assembly (key 223) shaft.
Two methods are available for adjusting the travel
sensor. You can use a multimeter to measure the
potentiometer resistance, or if you have a Field
Communicator, you can use the procedure in the
Calibration section. To use the multimeter, perform
steps 5 through 17. To use the Field Communicator,
skip to step 18.
Travel Sensor Adjustment with a Multimeter
5. Connect a multimeter set to a resistance range of
50,000 ohms. Measure the resistance between pins 1
and 3 of the travel sensor connector. Refer to figure
10-6 for pin location. The resistance should be
between 40,000 and 50,000 ohms.
6. Multiply the result in step 5 by 0.139 to get a
calculated resistance. The calculated resistance
should be in the range of 5560 to 6950 ohms.
7. Re-range the multimeter to a resistance of 7000
ohms between pins 2 and 3 of the travel sensor
connector. Refer to figure 10-6 for pin location.
8. Hold the arm assembly (key 91) in a fixed position
so that the arm is parallel to the housing back plane
and pointing toward the terminal box. Position the arm
assembly so that the outer surface is flush with the
end of the travel sensor shaft.
9. Adjust the travel sensor shaft to obtain the
calculated resistance determined in step 6, $100
ohms.
Note
In the next step, be sure the arm
assembly outer surface remains flush
with the end of the travel sensor shaft.
