• Make sure that the mounting surfaces of the photocells are flat
and that they enable the proper alignment between TX and RX.
• Make sure that the minimum and maximum clearances specified
in fig. 8 are observed.

• Pay attention in particular to the methods for securing the head
of the guide and the brackets to the ceiling. The head of the guide
will have to bear all the strain of opening and closing the door;
the ceiling-mounted brackets will have to bear all the weight of
AVIO500. In both cases, the wear and deformations which may
occur in time must be taken into consideration.
• The gearmotor should be mounted at the centre of the door, but
a small deviation from this position is permissible. This may be
required to mount the OSCILLATING ARM to the side of the handle
(Figure 9).

• Make sure that, in the position corresponding to the door, or
slightly to the side, (see positions A and B ) the conditions
are suitable for mounting the head of the guide; in particular, the
material should be sufficiently sturdy and compact.
Make sure that AVIO500 can be mounted on the ceiling along posi-
tion "C" using the mounting brackets.
If the door to be automated is an overhead type with springs or
counterweights, it will be necessary to install an OSCILLATING
ARM, hich must be mounted next to the handle (Figure 9).
• Make sure that distance [E] in Figure 10, i.e. the minimum dis-
tance between the upper side of the guide and the maximum
point reached by the upper edge of the door, is no shorter than
65 mm and no longer than 300 mm. Otherwise AVIO500 cannot be
installed.

If the door closes a room that has no other means of access, we
recommend installation of the EXTERNAL RELEASE IT (figure 11
and 11a). In fact, in this situation, a simple power failure may pre-
vent access to the area.
N.B.: the oscillating arm and external release kit are supplied with
the related assembly instructions.
