4.8 LEARNING OF THE MECHANICAL STOP
POSITIONS
Once the connected devices have been learned, the mechan-
ical stop positions must be learned (maximum opening and
maximum closing). This procedure can be carried out in three
different ways: automatic, manual and mixed.
In automatic mode, the control unit learns the mechanical stops,
calculates the most appropriate gate leaf offsets and calculates
the slowdown points “A” (“Figure 15“).
a
Before starting the self-learning procedure in auto-
matic mode, verify that the motor force is suited to
the type of motor being used (see paragraph “Level
2 programming (adjustable parameters) - Function
L6“).
In manual mode, the positions (“Figure 15”) are programmed
one-by-one, by moving the leaves to the desired points. The po-
sition to be programmed can be identied when one of the eight
LEDs “L1...L8” ashes (see “Table 4“).
In the mixed mode, it is possible to run the automatic procedure
then, using the manual procedure, modify one or more positions.

The “slowdown” conguration (LEDs “L5” and
“L6”) can be done “manually” after conguring the
closing and opening positions.

To effect the automatic learning procedure:
1. simultaneously press and hold the and
g
buttons
h
2. release the buttons when LEDs “L3” and “L4” start ash-
ing quickly (after roughly 3 seconds)
3. check that the automation carries out the following ma-
noeuvre sequences:
a. closing of motor M1 up to the mechanical stop
b. closing of motor M2 up to the mechanical stop
c. opening of motor M2 up to the mechanical stop
d. opening of motor M1 up to the mechanical stop
e. closing of motor M1 up to the mechanical stop
f. closing of motor M2 up to the mechanical stop.
m
If the rst two manoeuvres (a and b) are not “clos-
ing” but “opening” manoeuvres, press the
f
or
h
button to stop the learning phase. At
this point, invert the control wires (external posi-
tions with respect to the terminal) on the motor that
executed the opening manoeuvre and repeat the
self-learning procedure.
4. at the end of the closing manoeuvre (e-f) of the two mo-
tors, LEDs “L3” and “L4” switch off to indicate that the
procedure was carried out correctly.
m
If, during the automatic learning procedure, the
photocells or one of the devices connected to the
“stop” input intervene, the procedure interrupts and
LED L1 starts ashing. In this case, the self-learning
procedure must be repeated from the beginning.
l
The automatic learning procedure can be run again
at any time, even after the installation phase; for ex-
ample, after modifying the position of the mechan-
ical stops.
4.8.2 Learning in manual mode
m
The user has maximum 10 seconds to press the
buttons consecutively during the learning proce-
dure. After this time, the procedure terminates au-
tomatically and memorises the changes made up to
that time.
