Valve Switching Lever Height Adjustment

This adjustment should be performed on the low valve shaft after completing

adjustments to the vertical movement of the nozzle. (Refer to 7.1.3 “Nozzle Verti-

cal Movement During Pickup” for details.) The low valve shaft can be identified

by measuring the lower surface of the mechanical valve spool on all shafts. Raise

the spools and measure with a dial gauge, as shown in the diagram below.

1 Press the EMERGENCY STOP button to take the 200V down to 100V.

2 Adjust the position of the lever bracket so that the distance from the pin bracket

is 12 mm.

3 With the Y030 ST1 PICKUP SOL DISENGAGED ON, use the cam handle to

rotate the cam to 170°.

WARNING

• Press EMERGENCY STOP before performing this procedure.

• Exercise extreme caution when working on the machine if the cam

is not at its origin (0 deg.). Spring recoil can rotate the cam inde-

pendently.

4 Slide the jig (Z9827DGPJ029*) over the mechanical valve from the side, as

shown in the diagram.

5 Adjust the height of the bracket so that the distance between the lever and the

pin is 0.6 mm.

6 Remove jig (Z9827DGPJ029*).

7 Return the cam angle to 0°. Switch on the 1st nozzle UP/DOWN solenoid valve

in order to work the cam lever.

Check the servo counter to verify that the Proper data (PICK UP POS. NZ) is at

the pick-up height (approx. 4000 pulse position).

8 Use the cam handle to rotate the cam to 170°.
