04. Move the gate to the maximum opening position then position the first
section of the rack above the pinion of the gearmotor (fig. 8). Impor-
tant:- the total length of the rack must be the same as the length of
the gate leaf; - the distance between the pinion and rack must be
approx. 1-2 mm, to prevent the leaf weight from impairing gearmotor
operation.
05. At this point fix the rack onto the leaf (refer to the rack instruction
manual).
06. Manually slide the leaf to fix the other parts of the rack: Use the pinion
as a reference point and a spirit level to position each section of the
rack so that it is horizontal and perfectly aligned with the end placed
on the pinion. Note – To provisionally fix the rack parts to the leaf, use
the clamps as shown in fig. 9.
Warning – If the adjustment range possible with the rack is not suffi-
cient, the gearmotor height can be adjusted by means of the 2 hex
screws.
07. As the rack must not protrude from the gate leaf cut off any excess
section as required.
08. Manually complete a number of Opening and Closing cycles to ensure
that the rack slides smoothly along the pinion throughout the entire
length. Also ensure that the distance between the pinion and rack is
approx. 1-2 mm.
09. At this point tighten the 2 hex screws fully down.
10. Position (approximately) the two limit switch brackets on the rack (fig.
10) and manually move the gate for final fixture.
11. Fix the limit switch brackets as follows:
a) manually move the leaf to the opening position, leaving a distance
of at least 2-3 cm from the mechanical end stop.
b) slide the travel limit bracket on the rack in the opening direction until
the limit switch trips. Then move the bracket forward by at least 2 cm
and lock on the rack using the grub screws supplied.
c) perform the same operation to secure the Closing limit switch.
12. Then lock the gearmotor by means of the special key (refer to the
paragraph "Manually releasing or locking the gearmotor").

ELECTRICAL CONNECTIONS
At this point after installing the gearmotor and control devices (key-operat-
ed selector switch or pushbutton panels) and safety devices (emergency
stop, photocells, sensitive edges, flashing light) make electrical connec-
tions with reference to the following paragraphs and the example in fig.11-
11a.
The control unit has a series of functions selectable by means of dip-
switches (mini switches) and settings made via trimmers (fig. 12).
The input leds (fig. 12) Indicate the operating status of the automation
components, while the "OK" led (fig. 12), indicates correct operation of the
control unit. The control unit incorporates a multicode radio receiver.
Control Unit components (fig. 12):
a - Terminal board for aerial
b - Function selection dipswitches
c - Radio pushbutton
d - Work Time setting trimmer (TL)
e - Pause Time setting trimmer (TP)
f - Control input/output terminal board
g - Limit switch input connector
h - Flashing light/ courtesy light output terminal board
i - Capacitor connector
l - Motor power supply output connector
m - Power supply terminal board
n - Radio indicator led
o - Low voltage fuse (315 mA F)
p - Force setting trimmer (F)
q - "OK" Led
r - Transformer
s - Line fuse (5A F)
– To avoid hazardous situations, ensure that the control unit is dis-
connected from the power supply during connections.
– Incorrect connections can cause faults or hazards; therefore ensure
that the specified connections are strictly observed.
– There are precise standards regarding electrical safety and power-
operated gates which must be strictly observed at all times.
CAUTION!
Make all necessary connections with reference to the diagram in fig. 12
and the paragraph "Description of electrical connections".
To ensure correct electrical safety and optimal operation of the automation,
make the earthing connection on the terminal as shown in fig. 12.

Warnings:
– The NC (normally closed) type contacts, if not used must be "jumpered" and,
if more than one, placed in SERIES;
– The NO (normally open) type contacts, if not used must be left free and, if
more than one, placed in PARALLE;
– The contacts must always be mechanical and free of any type of voltage;
stage connections defined as "PNP", "NPN", "Open Collector" etc. are not
admitted.
4.1 - Initial start-up and connection check
CAUTION! The following operations described in this manual will be
performed on live electrical circuits and therefore manoeuvres may
be hazardous! Therefore proceed with care.
01.Power up the control unit and ensure that there is approx. 24 Vac
between terminals 8 and 9.
02.Ensure that the "OK" led, after emitting some quick flashes, emits
flashes at regular intervals.
03.At this point ensure that the leds related to inputs with NC contacts are
lit (all safety devices active) and that the leds related to the NO inputs
are off (no control present).
If this does not occur, check the various connections and functionality
of the various devices. The Alt input is activated, deactivating the
opening limit switch (FCA) and the closing limit switch (FCC).
04.Check the connection of the limit switches: Move the limit switch lever
and ensure that the relative limit switch trips, switching off the corre-
sponding led on the control unit.
05.Release the gearmotor and move the gate leaf to mid-travel and then
lock the gearmotor. This ensures that the gate leaf is free to complete
by opening and closing manoeuvres.
06.Ensure that the leaf moves in the correct direction according to the sig-
nal on the control unit. Important – This check is compulsory. If the
leaf direction is not correct with respect to the signal on the con-
trol unit, the automation may apparently operate correctly (the
"Open " cycle is the same as the "Close" cycle), but in practice
the safety devices may be ignored during execution of the Clos-
ing manoeuvre. In this case, the safety devices would only be
activated during the Opening manoeuvre, thus causing re-closure
against the obstacle, with disastrous consequences!
07.Ensure that the direction of motor rotation is correct: Send a brief pulse
signal to the SS input; the control unit always performs an Opening
manoeuvre first and therefore simply ensure that also the motor moves
in the direction of opening.
If this does not occur, proceed as follows:
a) disconnect control unit from the power supply;
b) rotate the motor power connector (l - fig. 12) and limit switch con-
nector through 180° (g - fig. 12));
c) then power up the control unit and repeat the check from point 7.
The "OK" led on the control unit (fig. 12), serves to indicate the operating
status of the latter:
- 1 regular flash every second = indicates that the internal microprocessor
is active and ready to receive commands.
- 1 quick double flash = indicates when the microprocessor reads a varia-
