5. Using a Field Communicator, perform the appropriate Travel Sensor Adjust procedure in the Calibration section.
Install the remote feedback unit on the actuator when the travel sensor adjustment is complete.
Note
If a Field Communicator is not available, perform the Travel Sensor Adjustment with Multimeter procedure below.
Travel Sensor Adjustment with a Multimeter (DVC6015)
1. Align the feedback arm (key 79) to the housing (key 1) by inserting the alignment pin (key 46) through the hole
marked “A” on the feedback arm. Fully engage the alignment pin into the tapped hole in the side of the housing.
Position the feedback arm so that the surface is flush with the end of the travel sensor shaft.
2. Connect a multimeter set to a resistance range of 50,000 ohms. Measure the resistance between terminals 1 and 3
of 1840 to 2300 ohms.
4. Re‐range the multimeter to a resistance of 3000 ohms between terminals 2 and 3 of the remote feedback unit.
Refer to figure 6‐8 for terminal location.
5. Adjust the travel sensor shaft to obtain the calculated resistance determined in step 3,
$
100 ohms.
Note
In the next step, be sure the feedback arm surface remains flush with the end of the travel sensor shaft.
6. 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 3,
$
100 ohms. Paint the screw
to discourage tampering with the connection.
7. Disconnect the multimeter from the travel sensor connector.
8. Travel sensor adjustment is complete. Install the remote feedback unit on the actuator.
DVC6025 Feedback Unit
Refer to figure 7‐5 for DVC6025 key number locations.
1. Insert the travel sensor assembly (key 223) into the housing. Secure the assembly with screw (key 72).
2. Connect the travel sensor assembly 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.
