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
----------
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)
----------
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.
N:Pump speed
Q:Injection quantity
V:Output voltage
A:Adjusting point
