8. Confirm that surface C of the cylindrical jig can slide in under the plate jigs, and that
surface D of the cylindrical jig cannot.
9. Under these conditions confirm that both of the plate jigs are securely clamped and
cannot move.
Main Table Lifter Plate Stoppers
In order to enhance the loading of panels on the XP series machines lifter plate stoppers
have been added. These keep the lifter plate parallel to the conveyor belt and in doing so
prevent the lifter plate from sticking at the upper limit position. To adjust the stoppers carry
out the following procedure:
1. Lower the lifter plate.
2. Adjust the position of the stoppers so that the lifter plate rests 0.5mm below the top
surface of the conveyor belt.
3. Refer to the diagram below and adjust the stoppers for both the fixed and adjustable rails:
Post Adjustment Checks:
1. Ensure that the clamper motion is smooth when the main table is raised and lowered.
2. Ensure there is sufficient clearance between the back-up pins and the under side of a
clamped board.
3. Confirm that the minimum (0.8mm) thick board and the maximum (4.0mm) board can be
clamped correctly.

4.5 Main Table Pneumatic Switch Adjustment
Note: Before proceeding with these adjustments, confirm that the lifter plate flatness
check (4.1) is complete.
Fast Down Adjustment
1. With the lifter plate raised, adjust the position of the cam so that there is a gap of 1mm
between the cam and the pneumatic switch roller.
Fast Up Adjustment
2. With the lifter plate raised, adjust the position of the cam so that there is a gap of 3mm
between the cam and the pneumatic switch roller.
4.6 Lifter Upper/Lower Limit Sensor Adjustment
1. Raise the main lifter and adjust the flag so that the upper limit sensor turns ON when a
4mm thick board is clamped, and turns OFF when a 4.8mm thick board is clamped.
2. With the main lifter lowered, adjust the flag at the lower limit sensor side so that it is
positioned 1mm past the point where the sensor comes ON.
3. Ensure that the I/O X024 MainStLftUpChk is ON when the lifter is at its upper limit, and
X025 MainStLftDwnChk is ON when the lifter is at its lower limit.
4. Ensure that there is no vibration when the lifter is raised and lowered.

Checking the Lifter Speed
1. Select [Manual Operation] – [Conveyor Operation] – [Main Lifter Up/Down] to raise and
lower the main lifter. The travel time should be in the following range:
Moving UP 400 – 600 ms
Moving DOWN 700 – 900 ms
Note: If the travel time is not in the range, re-adjust the main lifter speed controllers.
4.7 Adjusting the Main Stopper
Measuring jig: Plate jig (AJPJ-0060)
Main stopper adjustment
1. Select [Maintenance A] – [I/O Check] – and turn Y02A
MainStationStp OFF to lower the main stopper.
2. Lower the lower limit sensor (I/O X01F
MainStStpOffChk) until it turns OFF.
3. Raise the lower limit sensor, and lock the sensor 1mm
above the point it first turns ON.
4. 4.Select [Maintenance A] – [I/O Check], and turn ON
I/O Y02A MainStationStop to raise the main stopper.
5. Raise the upper limit sensor (I/O X01E
MainStStpOnChk) until it turns OFF.
6. Lower the upper limit sensor, and fasten the sensor
1mm below the point the sensor first comes ON.
7. Adjust the position of the main stopper as is shown in the following diagram:
