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.

NOTICE
Old/new clamping unit
A combination of old and new clamping units is possible.
Before installing a new clamping unit (version 2), make sure that your machine has
SW706.1 SP1 with Hotfix 4 or higher.

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.

Fig.309: Removing the clamp
► Remove the two screws (2) fastening
the clamp(1). These are on the side of
the conveyor side which faces away
from the clamp.
Make sure that you do not loosen or
remove any other screws !
CAUTION!
The screws fastening the clamps may
only be loosened if the clamps have
already been fixed in place with a spe-
cial screw!
.
Installation
Fig.310: Preparing the clamp
► Clamp an 8 mm Allen key(1) into the
clamp(2). Make sure you align it cor-
rectly.
This achieves a straight installation position.
Fig.311: Fitting the clamp
► Move the adjustment unit(2) by care-
fully pulling on the width adjustment
belt under the installation location of
the clamp(1).
► Loosely fasten the clamp into place
with two screws(3) (Allen key5).
► Let the clamps lie flush at the side(4),
set a gap of 1.1mm between the
clamps and the adjustment unit and
then tighten the two fastening screws
with a torque of 8 Nm.
► Set the sensor switch(5) so that it has
a distance of 0.3mm to the adjustment
unit.
► 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.
