5. INSTALLATION OF THE AUTOMATION SYSTEM
5.1.
PRELIMINARY CHECKS
To ensure trouble-free operation, make sure that the gate
(whether existing or yet to be installed) has the following
specifications:
•
max. weight of single leaf 500 Kg
•
max. length of single gate leaf 3.5 m with levers for 110°/180°
opening
•
max. length of single gate leaf 2 m with levers for 140° opening
•
strong and rigid leaf frame
•
smooth gate movement, with no stiff points
•
min. clearance between bottom edge of gate and ground
as in fig. 6/a (where 's' = thickness of guide bracket)
•
mechanical travel stops.
If any welding or brazing has to be done on the gate, do this
before installing the automation system.
The condition of the gate directly affects the reliability and safety
of the automation system.
5.2
INSTALLATION OF LEAF SUPPORTING FOUNDATION
BOX
Proceed as instructed below:
a) existing gate with fixed hinges
•
Remove the gate.
•
Remove the bottom hinge.
If the gate cannot be removed, place blocks under its bottom
edge to support it.
b) existing gate with adjustable hinges
•
Remove the bottom hinge.
•
Slacken off the top hinge.
•
Swing the leaf around the axis of the top hinge (fig. 4).
c) New gate to be installed
•
Fit just the top hinge. If possible use an adjustable hinge.
1) Dig out a hole for the foundation box as shown in fig. 5.
N.B.: Depending on the nature of the ground, it may be necessary
to cast a bed of quick-setting concrete at the bottom of the hole
to avoid subsidence in future.
2) Place the foundation box in the hole, respecting the
dimensions given in fig. 6/a-b-c.
The center of the pivot on the foundation box must be perfectly
aligned with the leaf's axis of swing fig 6/a-b-c).
N.B.: Use of the gear plate for 180° opening allows the housing
case to be embedded in any position. The alignment of the pin
present on the case with the leaf's axis of rotation must be
respected at all times (fig. 6c).

3) Lay down a PVC tube of diameter 35 mm through which to
pass a 4 core electrical cable. The tube must reach from the
box the control unit (fig. 7 ref.A). Lay a second tube to drain
off rain water, from the box to the nearest drain (fig. 7 ref.B).
B
4) Fix the box in place with a casting of concrete.
