àChecking the Positions of Copper Disk Plate and Solenoid Coil Core Slit

TRegarding the workload unit, positions of copper disk plate and solenoid coil core slit have been adjusted before mounting the frame so that they will not touch each other while the plate is rotating. However, due to positional distortion caused by tightening the bolts while the frame is being mounted, the copper disk plate may touch the core. (Fig. 1)

TRotate the copper disk plate slowly to check if it does not touch the core. If it does, it is necessary to eliminate the positional distortion caused by the tightening.

Correction Method

Correction can be made by tightening the frame-side nuts of the workload reinforcing metal base. Tighten the metal base toward the direction in which the positional correction of the copper disk plate should be made, until the plate comes close to the center of the core

slit (Fig. 1). (See the Section ES-4 "Correcting the Position of Solenoid Coil.")

1.After checking the correction direction, use a wrench to tighten the frame-side nut of the workload unit reinforcing metal base. Give the even tightening to both right and left sides.

2.As shown in Fig. 2, set a cable for measuring coil current in between the CN-1 female connector and the CN-1 male connector at the side of power supply board, and connect the cable to an ammeter.

3.Turn on the power switch of the main unit, set the control unit to the manual mode, select the torque at 4.0kg·m, and start the system.

4.Using a blade-head screwdriver, adjust the potentiometer on the power supply board so that the meter reading shows the coil current which is specified on the solenoid coil of the workload unit.

Example:As shown in Fig. 3, when 630 is indicated, adjust the potentiometer so that the coil current will be 630mA.

5.After having adjusted the coil current, remove the measuring cable, and connect the female connector of the CN-1 cable directly to the male connector at the power supply board side.

6.Fix the cable onto the seat pipe with cable holders.

àAdjusting the Flywheel

1.Adjust the flywheel by referring to the Section MS-3 "Adjusting the Flywheel."
