1.12.3 Clutch Meshing Check Sensor Amp Adjustment

Adjust the sensor amp so that it goes off when the clutches mesh properly and it goes on

when the clutches do not mesh properly and the dog is pushed down.

Remove the cover of the amp and follow the procedures below.

Note: Be careful not to drop the cover inside the machine.

1. Set the setting switch to “D ON”.

2. Set the mode selector switch to “SET”. The digital display will then indicate “1”.

3. With the clutch engagement sensor on (sensor is detecting the hole in the dog),

press the [TUNING] button. The digital display will then indicate “2”.

4. With the clutch engagement sensor off (sensor is not detecting the hole in the dog),

press the [TUNING] button. The digital display will then indicate “9”.

5. Set the mode selector switch to “RUN”.

6. After completing the amplifier setting procedure, verify that the digital display

indicates 0 ~ 1 when the sensor is on, and 8 ~ 9 at all other times.

1.13 Mechanical Valve Switching (Station 13)

Point

The station 13 mechanical valve is used to switch the vacuum off inside the nozzle. This

releases the negative pressure in the nozzle, and the nozzle can no longer hold a part.

Verify that parts which fail vision processing are discarded at station 13.

1.13.1 Valve Switching Unit Position Adjustment

This adjustment should be performed on the high valve head after completing adjustments to

the vertical movement of the nozzle during the placement (Refer to 1. 10 “Nozzle Vertical

Movement During Placement” for details). The high valve head can be identified by its

height. The heights of the spool lower surface are measured for all placing heads with spools

lifted, and the highest one is referred to as the high valve head.

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. Use an inching operation and move the high valve head to 12 station.

3. Attach the centering jig to the mechanical valve of the high valve head.

Note: Put the 0.2 mm spacer between the fixing bolt and the mechanical valve in order to

avoid any scratch to the mechanical valve.

4. Move the high valve head to station 13.

5. Use the cam handle to rotate the cam to the following cam angles:

CP-732E : 194°

CP-742ME/CP-742E : 190°

Make sure that the pusher is inserted smoothly to the hole at the bottom of the

centering jig. If not, loosen the fixing bolts and adjust the position of the valve

switching unit.
