Fig.307: Fitting the clamp
► Place a 0.3 mm feeler gauge (3) between the clamp (1) and cylinder unit (2).
Two feeler gauges are used in the diagram for more clarity.
The feeler gauge should not lie over the parallel pin(7).
► Place a 0.15 mm(4) feeler gauge between the clamps and the clamping surface(5).
► (6) Press the clamps at the same time towards the cylinder unit and towards the clamping sur-
face and then tighten the clamps with a torque of 8Nm.
► Check the distance under the clamps with a 0.25 and 0.3mm feeler gauge. The 0.25 mm
feeler gauge should just have enough room while the 0.3 mm one should not have room to
move.
► Check the distance between the clamps and the clamping surface with a 0.1 and 0.15mm
feeler gauge. The 0.1 mm feeler gauge should just have enough room while the 0.15 mm one
should not have room to move.
► Follow the removal instructions in reverse order for further installation. Also observe the fol-
lowing instructions:
– Check the input/output functions in the software to make sure that the adjustment units
with all sensors are recognized for all conveyor sides.
– Perform calibration of the fixed conveyor sides on the left and right. If you do not, not all
conveyor sides will be calibrated (see7.10.3 "Calibrating the Conveyor Rails" [}301]).
This calibration is needed to ensure that the conveyor sides are positioned correctly.

Troubleshooting
NOTICE
Insufficient clamping power
If the conveyor side clamps are no longer clamping enough, this could be because the con-
veyor side has been moved without the brakes (clamps) being released. In this case, pro-
ceed as follows:
► Remove the clamping unit and check its friction surface. If this is no longer rough,
clean the surface with "universal sanding cleaner". Carefully remove any aluminum
shavings on the friction surface.
► Readjust the clamps as described above and then tighten the screws with a torque of
8 Nm.
► If you are unable to set the parallelism of the conveyor sides with the width adjust-
ment, inform your SIPLACE service team.

1. Clamp
2. Sensor switch
3. Fastening screw for sensor switch
Removal
► Use the software to move the conveyor sides into a position which allows you best access.
The sides must move freely. Fix all three clamping units into place with one screw each, so
that the clamp is not able to exert any force onto the conveyor side.
7.2 "Loosening the Conveyor Side Clamps" [}207]
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
