(VR) measurement voltage (I) Part number of the control unit (G) Apply red paint. (H): End surface of the pump 1. Rack sensor adjustment (-0620) (1)Fix the speed control lever at the full position (2)Set the speed to N1 r/min. (If the boost compensator is provided, apply boost pressure.) (3)Adjust the bobbin (A) so that the rack sensor's output voltage is VR+-0.01. (4)At that time, rack position must be Ra. (5)Apply G at two places. Connecting part between the joint (B) and the nut (F) Connecting part between the joint (B) and the end surface of the pump (H)
