8.0 ARM CONNECTION
Warning: strictly comply with the steps described when fi xing the arms. Only remove the spring preload locking screw when specifi ed in
the instructions. Removal of the spring preload locking screw causes the pulleys and gears in the actuator to move. Keep your fi ngers
and other parts of the body well away from the moving parts during this operation!
Only carry out this operation after having disconnected the actuator from the electric power source.
After having fi xed the actuator and arm as shown in the diagrams on the previous pages (or using the drilling template in scale 1:1
supplied with each arm), connect the arm to the output shaft of the actuator as described in the following steps:
8.1
Choice of the spring load
The closing spring will have been preloaded in the factory with a standard value,
indicated by the red mark on the belt which matches the red mark on the pulley (see
fi gure alongside). Make sure that this condition has been complied with when the
product is installed. If this is not the case, comply with the instructions in chapter 3) on
page 18 in order to bring the preload back within the standard value.
Although the preload is fi xed, the power exercised by the spring during the closing
phase can be selected in the following way:
Connect the arm to the output shaft with the wing fully open so as to load the spring to
the minimum.
Connect the arm to the output shaft with the wing fully closed so as to load the spring
to the maximum.
Connection in an intermediate position loads the spring to a proportionally intermediate
value.
8.2
How to fi x the tapered end of the arm
Make sure that the puller nut screwed into the tapered end is positioned fully downwards,
as shown in the fi gure.
Make sure that the hole plug has been fi tted on the frame.
Connect the tapered end of the arm to the projecting pin.
Insert the fi xing screw and tighten it strongly.
8.3
Spring release
Warning:
When this operation is carried out, the components and door arm could start to move.
Keep your fi ngers and other parts of the body well away from moving parts during this
operation, or keep the wing blocked manually.
Move the spring locking screw from the locked position to the released position, as
described in the fi gure alongside. The door is now free to close by means of the spring.
Make sure that the door closes completely even when only open to a few degrees. If this
fails to occur, repeat the operations described in this chapter, but increase the closing
force as illustrated in section 8.1. Comply with the instructions in the following section
to disconnect the arm.
