0000001801 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
Adjusting method [applied voltage 10 V, dummy bolt (A)]
1. Hold the dummy bolt (A) against the control lever at position N = N1, Q = Q1.
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 V is V1.
3. Remove the dummy bolt (A) 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.
N:Pump speed
V:Output voltage
Q:Injection quantity
P:Boost pressure
B:Adjusting point
C:Checking point
Vi:Applied voltage
Q2 = idle lever position
