6. Adjust the rod.

• CP-732E

Adjust the rod so that there is ±0.02 mm difference between the slider groove

and the cam groove.

• CP-742ME/CP-742E

Adjust the length of the rod using the bolt to ensure that the distance between

the base of the slider and the cut out section in the cylindrical cam is within the

range of ±0.02 mm.

7. Reattach the placing head assembly in the original location.

Using the clutch alignment jig, reverse the removal procedures to attach the

assembly.

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.
