ADJUSTING THE SENSOR FOR DOUBLE LINERS

WARNING!
E0004P
This procedure can be performed only after the adjustment of the central sensor and the sensing spindle, described
above, have been completed.
A section of the race of the quality control unit cam, located where the caps enter the unit, is integral with a spring-loaded
block. A sensor which detects the movements of the block is connected to this.
As a result, when a sensing spindle detects caps with double liners, it pushes the spring loaded block upwards so that
the defective caps can be ejected.
NOTE: A cap with a properly formed liner (having the correct weight) must be used to make this adjustment.
- Place the cap under the sensing spindle.
- Position the roller (4) on the spindle in question near the flat section of the spring-loaded block (1).
- Check that the sensor (3) is activated.
- Set the sensor (3) so that it is 3 mm away from the fixed back-plate (2).
- Use the control keyboard to open the "Liner thickness" window on the "Machine drive system" data page (see
Instructions manual B). A number ranging from 34 to 38 will appear.
- Place a 2 mm shim under the roller (4) so that a 5 mm clearance is left between the fixed back-plate (2) and the sensor
(3).
- Set trimmer P2 (located on AP53 in the electrical cabinet) until the display shows "100".
- Remove the 2 mm shim from under the roller (4), thus restoring the initial condition.
- Adjust trimmer P5 until the "OUT" light comes on.
- Check that P5 is properly set. Place a 0.2 to 0.25 mm shim under the roller (4).
Under this condition, the "OUT" light should go out. If it does not, adjust trimmer P5 again.
WARNING!

Only highly qualified specially trained personnel can access the electrical components (see chapter 3 - SAFETY
EQUIPMENT AND PRECAUTIONS).
