3.12 PCB Set Check Sensor Adjustment
1. Adjust the sensor BKT so that the light axis comes to the center of the reference pin
and secondary pin block hole.
2. Set the sensor so it turns OFF when both the reference and adjustable pins move down
1.0 to 1.5mm.
3. As for the adjustable pin, the sensor should react at maximum, mid and minimum
pitches. Make sure that the green LED is always on.
4. Check the sensor reaction in I/O

3.13 Main Conveyor PCB Clamping Claw Check and Adjustment
3.13.1 (Part 1) Claw Positioning Adjustment
1. Check that the reference pin switch valve is set to “Mark Ref”.
2. Lock the rail-clamping claw at the closed position by solenoid valve.
3. Check that all the individual claws are loose.
4. There is some play in the position of the rail-clamping claw center bracket, so check that this is set
at the center of the play.
5. The next step is to lock all the individual claws. When these are locked, the clearance between the
tip of the claw and the guide rail should be in the range of 0.03 – 0.10 mm. (A) Each claw should be
locked using a 4Nm torque wrench. However, before proceeding to lock each claw, there are some
other considerations to bear in mind. Refer to figure 25.

6. Proceed to lock each claw making sure that the clearance values are within the ranges shown
above. It may be useful to lock the two center claws and the two claws at both ends of the rail first,
then proceed to lock the claws in between. Remember that clearance between the tip of the claw
and the guide rail should be in the range 0.03 to 0.10 mm. The claw is attached to the rail by two
3mm bolts. Tightening the top bolt will increase the clearance, tightening the bottom bolt will
decrease the clearance.
3.13.2 (Part 2) Claw Float Adjustment
1. Set the reference pin switch valve to “Pin Ref”.
2. Place a 4mm thick PCB in the main conveyor clamper.
3. Activate but do not lock the adjustable rail clamping solenoid.
4. At this position, there should be 0.5mm clearance between the clamper claw tips and the PCB.
5. Use the adjusting bolt on the claw float cylinder to set the clearance at 0.5mm. Note that the
clearance will vary slightly at different points on the clamper rail. Set the 0.5mm clearance at the
narrowest point.
6. On the fixed rail side, set the position of the clamping claw float sensor flag so that the sensor LED
is OFF when a 4mm thick PCB is clamped and ON when a 4.5mm PCB is clamped. Note that the
clamping solenoid should be activated but not locked for this adjustment. I.e. In this case “clamped”
means press the clamping solenoid once but do not lock it. Note: the sensor is Dark-On so when the
LED is Off the I/O input is ON, and vice versa. I/O: (X032 PCB Set CLP OK).
* Note that 0.5mm clearance on both sides is the ideal. However, this may be difficult to
achieve. In such cases a rough balance between the two is acceptable.

3.13.3 (Part Three) Clamping Cylinder Sensor Adjustment
1. Check that PCBs in the range of 0.5mm to 4.0mm can be clamped smoothly.
2. There are three clamping cylinders and two sensors on each cylinder. On each cylinder, the upper
sensor is the CLAMP CHECK sensor, and the lower sensor is the UNCLAMP CHECK sensor.
3. For the UNCLAMP CHECK sensors, open the rail to its unclamp limit. At this position find the point
where the sensor LED turns ON then move it 0.5mm further toward the ON direction.
4. For the CLAMP CHECK sensors, set the sensor so that it is ON when a 4.0mm board is clamped
and OFF when a 5.0mm board is clamped. Note that the clamping solenoid should be activated but
not locked for this adjustment. I.e. In this case, “clamped” means press the clamping solenoid once
but do not lock it.
5. Finally confirm that the CLAMP CHECK SENSORS are ON when the clamper rail is clamped with
no PCB in place.
6. Check the Clamping Cylinder Sensor and Valve reaction in I/O.
