Test data Ex:

0000001801 V-FICD ADJUSTMENT

Adjustment of the V-FICD 1. Adjust the actuator rod to obtain L1. 2. Apply negative pressure P1 to the actuator and confirm the full stroke. (A) actuator shaft (B) Control lever
----------
L=1+1mm P1=-53.3kPa(-400mmHg)
----------
L=1+1mm

0000001901 V-FICD ADJUSTMENT

Adjustment of the V-FICD 1. Adjust the stroke using the actuator adjusting screw so that the stroke is L when negative pressure P1 is applied to the actuator. (A) Control lever (B) Lock nut (Tightening torque T) (C) Actuator (D) stroke adjusting screw
----------
L=0.9+-0.2mm P1=-53.3kPa(-400mmHg) T=1.2~1.5N-m(0.12~0.15kgf-m)
----------
L=0.9+-0.2mm T=1.2~1.5N-m(0.12~0.15kgf-m)

0000002001 POTENTIOMETER ADJUSTMENT

Potentiometer adjustment (oval standards) With the control lever a from the idle position (gap L1 between the lever and the idle stopper), measure the injection quantity at pump speed N1 and adjust the potentiometer for the corresponding output voltage.
