0000001801 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
Adjustment method [supply voltage Vi, dummy bolt (A)]
1. Hold the dummy bolt (A) against the control lever at position N = N1 and Q = Q1 and fix using the lock nut.
2. When adjusting the potentiometer, position the control lever to contact the dummy bolt (A).
Adjust the potentiometer so that the output voltage is V1.
3. After completing adjustment remove the dummy bolt (A). Confirm that the potentiometer output voltage is as specified at the control lever idle position and full position.
Dummy bolt and nut part number: corresponding to 146526-3300 (bolt) 42 (mm)
Corresponding to 013020-6040 (nut)
