INSTALLATION

1.1 O
VERALL DIMENSIONS
The main overall dimensions of the sliding gate are indicated in fig. 1, 2 and 3; the base plate dimensions are indicated in fig. 8, while the dimen-
sions of the adjustable base plate are indicated in fig. 28.
1.2 PRELIMINARY OPERATIONS
Before starting any type of operation, carefully read the instruction present in this manual.
Before starting installation, make sure that all parts are present (fig. 4), wear suitable work clothing and accessories and do not handle live electrical parts.
1.3 INSTALLATION MEASUREMENTS
The measurements indicated in fig. 6 and 7 for the excavation and those in fig. 11 for the positioning of the base plate, must be respected for
the correct installation of the gearmotor.
1.4 PRE-INSTALLATION CHECKS
Use on gates with a gradient or slope is NOT allowed.
Before installation, check that:
- the wheels of the gate have been fitted 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 floor stops are present.
1.5 LOCATION
If fixing directly to a concrete surface, choose a position equivalent of the area outlined in fig. 6, or as in fig. 7 if an excavation has to be made.
1.6 BASE PREPARATION
Dig a sufficiently wide foundation that is at least 15 cm deep. Introduce a protective sheathing for the cables.
1.7 FIXING OF THE BASE PLATE
Note: 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 fig. 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 (fig. 9). Note: the threaded section must be protruding by no more than 40 mm
in order to secure the gearmotor (fig. 10). Cover with concrete, making sure that the ties are well imbedded; the base plate must be perfectly
level and 1 or 2 cm (fig. 11) from floor level and approx. 50 mm from the gate (fig. 7).
Note: The gearmotor can also be fitted without the base plate, using 4 foundation bolts on a level concrete surface making sure that
the measurements indicated in fig. 6 are respected.
Optionally, a height adjustable base plate can be used. In this case the fixed ties must be welded to the track and after locked with 4 expansion
bold M12x120 (see fig. 29). The adjustable base plate is then secured as indicated in fig. 30.
In this way the gearmotor can be adapted to an already existing system; the measurements indicated in fig. 29 must be respected.
1.8 SECURING OF THE GEARMOTOR
Remove the 4 locking nuts from the threaded section of the ties, position the gearmotor as illustrated in fig. 13, then secure it using the washers
and previously mentioned nuts (fig. 14). Pass the cables through the hole of the base plate.
Note: a hole has been arranged on the alumium base (fig. 13), under the transformer housing, to drain possible water deposit.
The same operations are also use for the adjustable base plate as indicated in fig. 31 and 32.
1.9 SECURING OF THE RACK
Having previously drilled the leaf, secure the rack with the 6.3 mm diameter self-tapping screws, see fig. 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 fig. 18, 19 and 20.
Note: the rack should run on the gearmotor gear for the entire width of its teeth (fig. 24).
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 fig. 27.
1.10 SECURING AND ADJUSTMENT OF THE LIMIT SWITCH PADS
Position each pad close to the end of the rack as in fig. 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 15 mm and a maximum of 18 mm should be maintained between the
gearmotor casing and the limit switch pads fitted on the rack in order for the automation system to function correctly (fig. 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 (floor stops) must be fitted, as shown in fig 5.
A single factor or combination of factors (thermal expansion, climate, frequency of use, etc.) may result in the position the gate
stops in changing over the course of the day, both when opening and when closing. Consequently, we cannot guarantee that the
gate will always stop in the same position.
2. MAGNETIC LIMIT SWITCHES (MASTER20QM)
During movement, the gate mounting the magnets fitted on the rack approaches the sensor installed on the gearmotor, and activates this sensor, conse-
quently stopping closure.
The magnets must be installed at a distance from the closing edge (X, fig. 17B) taking gate inertia into account. We recommend testing the magnets on the rack
