1. Load sensor adjustment
(1)Connect as shown in the above diagram and apply supply voltage V1.
(2)Hold the load lever (G) against the full side.
(3)Turn the shaft so that the voltage between (A) and (B) is V2.
(4)Hold the load lever (G) against the idle side.
(5)Adjust (D) so that the voltage between (A) and (B) is V2i.
(6)Repeat the above adjustments.
(7)Tighten the nut (F) at the point satisfying the standards.
(8)Hold the load lever against the full side stopper and the idle side stopper.
(9)At this time, confirm that the full side output voltage is V2f and the idle side output voltage is V2i.
----------
V1= 5+-0.02V V2f=0.15+0.03V V2i=2.35-0.03V
