Limit switches at opening
Four (4) positions can be selected for the limit switch of the outgoing chain.
As
seen above, t o program, adjust t he two dip -switches no.3 and no.4. Programming
is simple, immediate and can be carried out at any time by adjusting the two dip
-
switches as indicated in the following table.

Dip-switch
After the limit switches have been programmed, run a
few check manoeuvres. In
the event of error, programming can be repeated to give the desired track run.
Limit switches at closure
The limit switch at closure is automatic, electronically operated and cannot be
programmed. The actuator stops when the charg e is absorbed when the window
is completely closed and the weather stripping is completely depressed, or when
the charge absorbed is more than 10% of the nominal charge. In this case, at
maximum charge the actuator exercises a traction force of over 330N.
After each closure or intervention of the electrical protection mechanism,
the chain moves in the opposite direction for around 1,5/2,0 mm. This is to
loosen the tension of the mechanical parts and gives correct pressure to the
weather stripping.
TECHNICAL INFORMATION ABOUT FUNCTION
The chain operated actuator opens and closes windows by means of a steel chain
located inside the cover. Movement is powered by electricity which powers a gear
motor controlled by an electronic function device.
Window opening can be programmed to open at 100, 200, 300 and 400 mm
(see
respective chapter)
.
During closure the end course uses a self -regulating electronic process with
power absorption and therefore requires no regulation.
The actuator leaves the factory with factor y settings of +1 cm for the return course
which allows the actuator to be assembled without electricity, with the window
in
closed position after assembly is complete.
