5. When making adjustments, push the green button (on the valve) to turn the valve ON. Then,
manually toggle the valve ON and OFF to check the clearance. As a rule, set the clearance as
close to 0.04 as possible. (best condition)

2.10 Image Acquisition Timing Flag Adjustment
1. Adjust the two sensor flags “A” in fig 12, so that the two sensor LED’s turn ON when
rotating the Cam forward to 197 degrees. (Tolerance: 197 ± 1 degree)
2. Adjust flag “B” so the sensor lamp turns ON when rotating the Cam angle forward to 340
degrees. (Tolerance: 340 ± 1 degree). Ensure the LED remains ON for the duration of
time the flag is within the sensor.

3. The three sensors mentioned above serve the following purposes.
a. The vision system trigger sensor informs the VP card to take the component image
at 197 degrees. (station 5)
b. The part height trigger sensor informs the part height unit to take the component
thickness (nozzle length) image at 197 degrees. (station 6)
c. The dust check trigger sensor informs the part height unit when to check the
windows for dust etc. (checks from 110 to 340 degrees). (station 6)
Note: The three sensors mentioned above are NOT connected to the I/O. To monitor the
sensor operating conditions, check the LED’s at the following locations:

2.11 Cam Calibration Data Setting (0.03deg/pulse)
Since zero setting is not required on the CP-7 Series machines, (absolute encoder system
employed) a reference position called, “Origin Position Offset” is needed for tracking the cam
motor position. Follow the procedure below in order to set the origin position offset for the
cam motor under the following two conditions.
When the Cam Motor coupling has already been tightened:
1. With the machine power ON, press the Servo count tab at the bottom of the screen to display
the servo pulse counts.
2. Turn the cam (using the cam handle) until the Cam pulse counts are within 0 +/– 6000 and set
the cam angle to 0 degrees.
3. With the cam at 0 degrees and the pulse counts within the specified range, set this position
into calibration data as follows:
Press: [Maintenance] → [Calibration] → [Origin Pos Offset] → [CAM]
When the Cam Motor coupling has been released.
1. With the machine power ON, press the Servo count tab at the bottom of the screen to display
the servo pulse counts.
2. Ensure the cam is set at 0 degrees.
3. Rotate the cam motor shaft until the Cam pulse counts are within 0 +/– 6000.
4. With the cam at 0 degrees and the pulse counts within the specified range, tighten the
coupling to 33N.m
5. With the cam at 0 degrees and the pulse counts within the specified range, set this position
into calibration data as follows:
Press: [Maintenance] → [Calibration] → [Origin Pos Offset] → [CAM]
