Figure 7-6. Potentiometer Resistance Measurement
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.

DVC6020f Digital Valve Controller and
DVC6025 Remote Feedback Unit
Refer to figure 8-3 for DVC6020f and 8-8 for 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.
Note
For the 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
