11. 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 8, $100 ohms. Paint the
screw to discourage tampering with the connection.
12. Disconnect the multimeter from the travel sensor
connector.
13. For the DVC6030 SIS only, connect the travel
sensor connector to the PWB as described in
Replacing the Module Base.
14. Travel sensor replacement is complete. Install the
digital valve controller on the actuator as described in
the Installation section.
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.
15. For the DVC6030 SIS only, connect the travel
sensor connector to the PWB as described in
Replacing the Module Base.
16. For both the DVC6030 SIS and the DVC6035,
perform the appropriate Travel Sensor Adjust
procedure in the Calibration section.
Troubleshooting
If communication or output difficulties are experienced
with the instrument, refer to the troubleshooting chart
in table 7-3. Also see the DVC6000 SIS
Troubleshooting Checklist on page 7-18.
Checking Voltage Available
WARNING
Personal injury or property damage
caused by fire or explosion may occur
if this test is attempted in an area
which contains a potentially explosive
atmosphere or has been classified as
hazardous.
To check the Voltage Available at the instrument,
perform the following:
1. Connect the equipment in figure 2-25 to the field
wiring in place of the FIELDVUE instrument.
2. Set the control system to provide maximum output
current.
3. Set the resistance of the 1 kilohm potentiometer
shown in figure 2-25 to zero.
4. Record the current shown on the milliammeter.
5. Adjust the resistance of the 1 kilohm potentiometer
until the voltage read on the voltmeter is 11.0 volts.
6. Record the current shown on the milliammeter.
7. If the current recorded in step 6 is the same as that
recorded in step 4 (± 0.08 mA), the voltage available is
adequate.
8. If the voltage available is inadequate, refer to
Wiring Practices in the Installation section.
