NOTE:
1 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.

Note
For the DVC6025 feedback unit,
connect the potentiometer assembly
(key 223) wires to the terminals as
follows:
" terminal 1
red
white " terminal 2

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
