Test data Ex:

0000001801 POTENTIOMETER ADJUSTMENT

Adjusting method (applied voltage Vi, dummy bolt method) 1. Hold the dummy bolt against the control lever at position N = N1 and Q = Q1 and fix using the lock nut. 2. At potentiometer adjustment, with the control lever contacting the dummy bolt, adjust the potentiometer so that the output voltage is V1. 3. After completing adjustment remove the dummy bolt. Confirm that the potentiometer output voltage is as specified above at the control lever idle position and full position.

0000001901 V-FICD ADJUSTMENT

Adjustment of the V-FICD 1. Mount the V-FICD after the completion of potentiometer adjustment. 2. Confirm that the clearance between the control lever (B) and the actuator rod (A) is at least L2. 3. Insert the L1 shim between the control lever (D) and the idle set screw (C). 4. Adjust the stroke adjusting screw (E) so that the actuator moves through its full stroke, then fix using nut (F). Note When adjustment is not possible using the stroke adjusting screw (E), move the actuator rod position using (G), (H) and (I). Then, readjust the stroke using (E) and (F). 5. Apply negative pressure P1 to the actuator and confirm the full stroke. 6. After releasing negative pressure, re-confirm that the clearance between (A) and (B) is at least L2.
