0000001801 POTENTIOMETER ADJUSTMENT
Adjusting method [applied voltage Vi, dummy bolt (C)]
1. Hold the dummy bolt (C) against the control lever at position N = N1, Q = Q1.
Fix using the lock nut.
2. When adjusting the potentiometer, position the control lever against the dummy bolt (C) and adjust the potentiometer so that the output voltage is V1 (V).
3. Remove the dummy bolt (C) after the completion of adjustment.
Confirm that the potentiometer output voltage is within the above mentioned standards between the control lever's adjusting point and the idling position.

V:Output voltage
Q:Injection quantity
P:Boost pressure
A:Adjusting point
B:Checking point
Q2:Idle

Adjustment of the V-FICD
1. Confirm that microswitch and potentiometer adjustment are completed.
2. Adjust the actuator rod to obtain S1.
3. Apply negative pressure P1 kPa {P2 mmHg} to the actuator and confirm that it moves through its full stroke.

1. Fix the dummy bolt B so that the potentiometer output voltage V = V1.
2. Move the microswitch in the direction of the arrow shown below.
Fix the microswitch where it turns from ON to OFF.
3. Loosen dummy bolt B. Confirm that the potentiometer output voltage (V) is V1 where the microswitch turns from ON to OFF.
After completing adjustment, remove the dummy bolt.
