LIMIT SWITCH ADJUSTMENT

5.1 - Limit positions on opening and
closing
During the up and down movements, the motor stops the
shutter automatically when it reaches the limit switch posi-
tions (fig. 4): position "0" (shutter totally retracted) and po-
sition "1" (shutter totally extended). The factory settings of
these positions are very approximate, and therefore follow
the procedure below to adapt them to the specific dimen-
sions of the roller shutter concerned.
5.2 - Adjusting first limit position "0" and
then limit position "1"
01. Move the shutter to position "1".
 Align the adjustment screws with the respective
limit positions:
02. Stand in front of the shutter and note the following:
A) – Stand in front of the roller and observe at which
end the head of the motor protrudes: at the right end
or left end of the roller?
3 – English
A – motor on the left.
B – rolling shutter behind the roller.

B) – Stand in front of the roller and observe where the
unrolled part of the rolling shutter is positioned: is in
front of or behind the roller?
03. Then identify in Fig. 1 the diagram that corresponds
to situations "A" and "B" observed in point 02. Very
important – The identified diagram assigns a
specific limit position to be set on each adjust-
ment screw.
 Setting limit position "0":
04. Activate the shutter so that it moves towards position
"0" and wait for the motor to stop on activation of the
limit switch pre-set with the factory settings.
Caution! – If the shutter moves beyond the point at
which limit switch "0" is to be fixed, stop movement
and then activate the shutter to move it back to the
starting position; then turn the adjustment screw of
limit position "0" through a few turns in the direction of
the "–" sign and repeat the procedure from point 04.
05. Gradually turn the adjustment screw of limit position
"0" in the direction of the "+" sign, to the required stop
position "0". Note – on each turn of the screw, the
motor moves to stop in the new position.
 Setting limit position "1":
06. Turn the adjustment screw of limit position "1" through
a few turns in the direction of the "–" sign.
A – motor on the right.
B – rolling shutter in front of
the roller.

07. Activate the shutter so that it moves towards position
"1" and wait for the motor to stop on activation of the
limit switch pre-set with the factory settings.
Caution! – If the shutter moves beyond the point at
which limit switch "1" is to be fixed, stop movement
and then activate the shutter to move it back to the
starting position; then turn the adjustment screw of
limit position "1" through a few turns in the direction of
the "–" sign and repeat the procedure from point 07.
08. Gradually turn the adjustment screw of limit position
"1" in the direction of the "+" sign, to the required stop
position "1". Note – on each turn of the screw, the
motor moves to stop in the new position.
A – motor on the right.
B – rolling shutter behind the roller.
