7.1.4 Mechanical Valve Switching (ST1)
Point
The nozzle vacuum goes from OFF to ON with the movement of the mechanical valve
at station 1. Vacuum for part pick-up reaches the nozzle when the valve is open.
Checking the Position of the Pin Bracket
1 Press the EMERGENCY STOP button to turn off the 200V power, leaving only
the 100V power on.
2 Ensure that distance A (as seen in the figure below) is 8.9 mm for all heads. Use
a special jig (Z9827DGPJ029*) to check this distance.
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.

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°.
