10. Programming the actuator
10.1.
Stroke-end at opening
At one end of the actuator is a pin which can be adjusted
using a screwdriver and an indicator arrow (see photo) to
set stroke length (240 or 360 mm).
The actuator cover has two reference marks:
1 mark (240 mm stroke);
2 marks (360 mm stroke).
Attention:
never select 360 stroke when actuator is at 240 end stroke; inner
selector can irremediably brakes.
10.2.
Stroke-end at closure
The stroke-end at closure is automatic and cannot be programmed. The actuator
stops when the power encountered by the actuator when the window reaches
complete closure is absorbed and the seals are pressed right in, or when the
absorbed power is over 15% of the nominal power. In this case, at maximum load
the actuator exerts traction of over 280N.
After each closure or intervention of electronic protection devices, the chain will
move about 1 mm in the opposite direction to give correct compression to the seals
and release the mechanical parts.
Check that hinges and support brackets are rigidly attached to the window frame
and all screws correctly fixed into position. For aluminium window frames, do not
use self threading or self perforating screws as these will tear the profile after a few
manoeuvre; use metric screws with threaded inserts
(see indication on page 9)
.
11. Checking for correct assembly
Check that the window is perfectly closed at corners and that there are no
obstacles caused by incorrect positioning during assembly.
Check that when the window frame is closed the chain terminal is at least a
few millimetres away from the actuator body. This will ensure the window is
properly closed and seals are correctly compressed. In the event that this
should not be the case there is no guarantee that the window is closed
correctly.
Check that hinges and support brackets are aligned to each other and tightly
fixed against the window frame with screws fixed correctly into position.
Check that the window reaches the desired position according to the stroke-
end selected.
