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 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 (DVC6025)
1. Connect a multimeter set to a resistance range of 50,000 ohms. Measure the resistance between terminals 1 and 3
of the remote feedback unit. Refer to figure 6‐8 for terminal location. The resistance should be between 40,000 and
50,000 ohms.
2. Multiply the result in step 1 by 0.142 to get a calculated resistance. The calculated resistance should be in the range
of 5680 to 7100 ohms.
3. Re‐range the multimeter to a resistance of 7000 ohms between terminals 2 and 3 of the remote feedback unit.
Refer to figure 6‐8 for terminal location.
4. 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.
5. Adjust the travel sensor shaft to obtain the calculated resistance determined in step 2, $100 ohms.
Note
In the next step, be sure the arm assembly outer surface remains flush with the end of the travel sensor shaft.
