Belt tensioning
Proceed as follows for correct belt tensioning:
• Make sure the motor unit is positioned and fixed as per factory settings and is a position that guarantees belt centring
to the sliding area
• Loosen the fastening nuts on the encoder pulley unit

• Make sure that integrated automatism control module fastening bolt part.
C
is
loose and permits lateral movement.
• Move the integrated automatism
control module to the left to achieve
first belt tensioning level. Make sure
that the belt branches are visibly taut
(without any evident downward
folds).
• Firmly tighten module fastening
screws

Carriage start up
Reconnect the belt fasteners to the carriages
Fig.10
; tighten the
screws
B
making sure the position of the fasteners permits
good belt parallelism between the upper and lower branches.
Verify the correct disposition of the belt fasteners on the
carriages in touch with the automatism as indicated in
Fig. 23, 24 and 25
.
Lift the anti-derailment device so that the roller does not touch the
aluminium profile during sliding (
Fig.22
). Tighten the
screws
C
(
Fig.10
) without altering the chosen adjustment.
In touch with the automatism, verify the correct fixing
configuration of the belt clamp on the carriages, as indicate
in the figures:

WARNING
Incorrect anti-derailment device adjustment that puts the roller in contact with the aluminium profile causes excessive noise
during automatism use.
WARNING
An incorrect fixing of the belt clamp on the carriages causes alterations in the direction of the opening and closing wings. Verify
carefully the agreement of the connections between the belt and the carriages as indicated in the
Fig.25
,
