5 FINAL CHECKS AND START-UP
5.1 ADJUSTING THE MECHANICAL LIMIT
SWITCHES
To adjust the limit switches, proceed as follows:
1. close the shutter completely
2. press and hold the presser (A) upwards so as to allow the
limit switch adjusters to move freely
3. turn the adjuster (B) until the lowering switch (C) clicks (low-
ering limit switch adjustment completed)
4. turn the adjuster (D) by moving it towards the lifting switch
(E)
5. release the presser (A)

6. power the gearmotor
7. control the lowering of the shutter through the key selector
or button
8. verify whether the shutter stops in the desired position
9. to allow the shutter to stop in a different position during the
opening movement, change the position of the adjuster (D)
as shown previously
m
If the gearmotor is installed in the opposite direc-
tion, switch (C) will allow the shutter to stop while it
is lifted, while switch (E) will allow it to stop while it
is lowered. Adjust the cursors accordingly.
5.2 MANUALLY UNLOCKING AND LOCKING THE
GEARMOTOR
a
If the shutter is lifted before the limit switches are
adjusted, the gearmotor could get seriously dam-
aged. Carry out the procedure set forth in the "Ad-
justing the mechanical limit switches" paragraph.
Gearmotors equipped with an electric brake have a mechanical
unlocking system that allows for opening and closing the shutter
manually.
These manual operations should only be performed in case of a
power outage, malfunctions or during the installation phases.
To unlock the device:
1. loosen the lower part of the knob anti-clockwise until you
can

2. at this point, the shutter can be moved manually to the de-
sired position.
To lock the device, turn the knob clockwise all the way.

TESTING AND COMMISSIONING
6
These are the most important phases of the automation’s con-
struction, as they ensure maximum safety of the system. The test
can also be used to periodically verify the devices making up the
automation.
m
Testing and commissioning of the automation must
be performed by skilled and qualied personnel,
who are responsible for the tests required to ver-
ify the solutions adopted according to the risks
present, and for ensuring that all legal provisions,
standards and regulations are met, in particular all
the requirements of the EN 12445 standard, which
denes the test methods for checking door auto-
mations.
The additional devices must undergo specic testing, both in terms
of their functions and their proper interaction with the control unit.
Refer to the instruction manuals of the individual devices.
6.1 TESTING
To run the test:
1. verify that all the instructions stated in the “GENERAL
SAFETY WARNINGS AND PRECAUTIONS” chapter have
been strictly observed
2. check that the die-cast items are in good condition and are
not broken
3. check that the gearmotor is properly secured to the spring
support shaft
4. check that the electrical contacts are in good condition
5. check that the collar does not have any excessive axial
clearance
6. verify the adjustment of the limit switches by performing a
complete manoeuvre (up-down)
7. check that the gearmotor – when locked in any position –
does not move
8. check that the unlocking manoeuvre easily disengages the
gearmotor from the shutter (only for versions with brake).
6.2 COMMISSIONING
a
Commissioning can only be performed after all
testing phases have been successfully completed.
a
Before commissioning the automation, ensure that
the owner is properly informed of all residual risks
and hazards.
