4. Place a dial gauge on the top end of the cam lever and set the gauge reading to “0”. In this condition, the cam axis will be at its 0-degree position, and the nozzle UP/DOWN rod will be at its UP limit position. Verif…
1.10.2 Adjusting the Nozzle UP Limit Sensors
The nozzle UP limit sensor which detects the up limit position of the nozzle UP/DOWN
rod at station 9 is mounted inside the cam box. Adjust the mounting position of this
sensor so that it switches ON when the nozzle is at its UP limit position.
1. Press the EMERGENCY STOP button to take the 200V down to 100V.
WARNING
• Always be sure to cut off the 200V power before carrying
out any work.
• Exercise extreme caution when working on the machine if
the cam is not at its origin (0 deg.). Recoil of the cam
axis can endanger the operator.
2. Set the cam axis at the 0-degree position.
3. Activate the ST9 placing solenoid air cylinder (located in the cam box):
Execute the following I/O commands: [Maintenance] - [I/O Check] - [Standard I/O]
- [Y035 ST9 PLACE SOL ENGAGED] - [Output Signal ON]
The cam lever will then follow the cam axis.

4. Place a dial gauge on the top end of the cam lever and set the gauge reading to
“0”. In this condition, the cam axis will be at its 0-degree position, and the nozzle
UP/DOWN rod will be at its UP limit position. Verify that the nozzle UP limit
sensor is ON (X032 ST9 CYLINDER UPPER LIMIT is ON).
5. While observing the dial gauge, rotate the cam axis in the forward direction to
lower the nozzle UP/DOWN rod. Adjust the sensor’s mounting position so that
the sensor switches OFF (X032 ST9 CYLINDER UPPER-LIMIT switches OFF)
when the rod has been lowered 0.3 to 0.4 mm.
6. Adjust the sensor’s mounting position by loosening the sensor lock screw and
sliding the sensor in the front/back directions.

1.10.3 Adjusting the Nozzle DOWN Limit Sensors
The nozzle DOWN limit sensor which detects the down limit position of the nozzle
UP/DOWN rod is mounted inside the cam box. Adjust the mounting position of this
sensor so that it switches ON when the nozzle is at its DOWN limit position.
Note: When performing the DOWN limit sensor adjustment after the UP limit sensor adjustment,
remove the dial gauge from the machine to avoid interference between the dial gauge and
the cam lever.
1. Press the EMERGENCY STOP button to take 200V down to 100V.
WARNING
• Always be sure to cut off the 200V power before carrying
out any work.
• Exercise extreme caution when working on the machine if
the cam is not at its origin (0 deg.). Recoil of the cam
axis can endanger the operator.
2. Set the cam axis at the 0-degree position.

- [Y035 ST9 PLACE SOL ENGAGED] - [Output Signal ON]
The cam lever will then follow the cam axis.
4. Use the cam handle to rotate the cam to 180°.
