(A) Screw for precise adjustment (B) Pre-adjustment screw (C) Control rack, rack decrease direction (D) Rack limit 1. Solenoid boost compensator adjustment (1)Supply DC: V1 to the solenoid terminals and confirm solenoid operation. (2)With the solenoid ON, calculate L1 from the value of R1. [L1 = La - (10.5 - R1) +-0.2] (3)Adjust (B) to obtain L1. (4)Assemble the solenoid to the governor. (5)With the solenoid ON, readjust (B) so that R1 is within the allowance a. (6)With the solenoid OFF, perform all governor adjustments except rack limit adjustment. (7)Set the pump speed at N1 and turn the solenoid ON. (8)Adjust (A) so that R1 is within the allowance range a. (9)Set the pump speed at N1 and fix the load lever in the full position (10)Turn the solenoid switch ON and OFF several times and confirm that the difference in rack positions is within L2. (11)Set the rack limit. (12)Stamp the solenoid valve.
