The main overall dimensions of the sliding gate are indicated in
fi g. 1, 2 and 3; the base plate dimensions are indicated in fi g. 8,
while the dimensions of the adjustable base plate are indicated in
fi g. 28.
Before starting any type of operation, carefully read the instruction
present in this manual.
Before starting installation, make sure that all parts are present
(fi g. 4), wear suitable work clothing and accessories and do not
handle live electrical parts.
INSTALLATION MEASUREMENTS
The measurements indicated in fi g. 6 and 7 for the excavation
and those in fi g. 11 for the positioning of the base plate, must be
respected for the correct installation of the gearmotor.
Before installation, check that:
-
the wheels of the gate have been fi tted so that the gate itself is
stable, and that they are in good condition and
working correctly;
-
the track is free, straight and clean along its entire length and
has the stops at each end;
-
the upper guide is inline with the track, and is greased and
allows the leaf a play of approx. 1 mm;
-
check that the fl oor stops are present.
If fi xing directly to a concrete surface, choose a position equivalent
of the area outlined in fi g. 6, or as in fi g. 7 if an excavation has to
be made.
Dig a suffi ciently wide foundation that is at least 15 cm deep.
Introduce a protective sheathing for the cables.
N.B. The foundation counterplate is positioned correctly when
the arrows on it are pointing in the following directions: one
towards the gate and the other to the left (1 fi g. 12).
Once the foundations are ready, prepare the base plate by inserting
the threaded ties into their holes, securing them on the lower face
with the 4 narrow nuts and with the 4 locking nuts on the upper
face (fi g. 9). N.B.: the threaded section must be protruding by
no more than 40 mm in order to secure the gearmotor (fi g. 10).
Cover with concrete, making sure that the ties are well imbedded;
the base plate must be perfectly level and 1 or 2 cm (fi g. 11) from
fl oor level and approx. 50 mm from the gate (fi g. 7).
N.B.: The gearmotor can also be fi tted without the base plate,
using 4 foundation bolts on a level concrete surface making
sure that the measurements indicated in fi g. 6 are respected.
Optionally, a height adjustable base plate can be used. In this case
the fi xed ties must be welded to the track and after locked with 4
expansion bold M12x120 (see fi g. 29). The adjustable base plate
is then secured as indicated in fi g. 30.
In this way the gearmotor can be adapted to an already existing
system; the measurements indicated in fi g. 29 must be respected.
SECURING OF THE GEARMOTOR
Remove the 4 locking nuts from the threaded section of the ties,
position the gearmotor as illustrated in fi g. 13, then secure it using
the washers and previously mentioned nuts (fi g. 14). Pass the
cables through the hole of the base plate.
The same operations are also use for the adjustable base plate as
indicated in fi g. 31 and 32.
Having previously drilled the leaf, secure the rack with the 6.3 mm
diameter self-tapping screws, see fi g. 16.
It is extremely important that the installation measurements
and the distance between the teeth of the gear and the teeth of
the rack are respected, as indicated in fi g. 18, 19 and 20.
Note: the rack should run on the gearmotor gear for the entire
width of its teeth (fi g. 24).

SECURING OF THE RACK
There are two available types of rack: the standard enbloc type
and the sectional type of which each single piece measures 50 cm
in length fi g. 27.
SECURING AND ADJUSTMENT OF THE LIMIT SWITCH
Position each pad close to the end of the rack as in fi g. 17.
Manually manoeuvring the leaf, position the pads so that they
make slight contact with the microswitch lever just before the
intervention of the mechanical stops at the end of the track, and
tighten the screws.
The manufacturer advises that a distance between a minimum
of 13 mm and a maximum of 18 mm should be maintained
between the gearmotor casing and the limit switch pads fi tted
on the rack in order for the automation system to function
correctly (fi g. 23).
The contact point of the limit switch pads with the spring
should also be lubricated with a little oil in order to help
sliding and prevent the spring from being compressed.
Note: for complete safety, the mechanical stops with rubber
cap (fl oor stops) must be fi tted, as shown in fi g 5.

ADJUSTMENT OF THE ELECTRONIC/ELECTRIC
WARNING: Check that the impact force value measured at the
points foreseen by the EN 12445 standard is lower than that
indicated in the EN 12453 standard.
The adjustment on MASTER12Q is already preset during the
programming of the control unit and can in any case be set (see
instructions K123M).
The adjustment of MASTER20Q can be performed through the
control unit, see instructions D704M.
The adjustment of MASTER20T can be performed through the
control unit, see instructions D703M.
N.B. The MASTER series has a microswitch that cuts-out the
motor when the casing is opened, A fi g. 25 (the control unit
remains live).
Make sure that the gearmotor is disconnected from the power
supply before performing any operations.
To make the connections, remove the gearmotor casing, pass
the cables through the holes on the base plate (when used) and
through the lower section of the gearmotor. Then arrange the
cables for the connection to the control unit terminal block that is
located in the electrical components support.
The distance between the control unit and the motor must not
exceed 10 – 12 m.
