MILORD AUTOMATED SYSTEM
The MILORD automated system for residential sliding gates is an electro-
mechanical operator which transmits motion to the leaf through a pinion
gear suitably coupled to a rack fitted on the gate.
The non-reversing system ensures mechanical locking when the motor
is not operating and, therefore, installing a lock is unnecessary. A handy
release facility makes it possible to move the gate in the event of a power
cut or fault.
This operator has no mechanical clutch, and, therefore, requires a control
unit with electronic clutch.
In the “C” versions, MILORD operators have the electronic control unit built
into the operator body.

3. INSTALLING THE AUTOMATED SYSTEM
3.. PRELIMINARY CHECKS
To ensure a correctly operating automated system, the structure of the
existing gate or gate to be built must satisfy the following requirements:
the weight of the gate must comply with the data in the technical spe-
cifications table;
sturdy, rigid gate structure;
smooth leaf surface (without any projections);
smooth, uniform gate movement, without any friction during the entire
travel;
no sideward leaf swings;
top and bottom sliding systems must be in excellent condition. It is prefe-
rable to use a ground-level guide with rounded groove to obtain reduced
sliding friction.
only two sliding wheels;
mechanical safety stops required to prevent the danger of gate derail-
ment; these stops must be firmly secured to the ground or to the ground-
level guide at about 40 mm beyond the travel limit position.
no mechanical closing locks.
We advise you to carry out the metalwork jobs before installing the auto-
mated system.
The condition of the structure directly influences the reliability and safety
of the automated system.
3.2. INSTALLING THE OPERATOR
Assemble the foundation plate as in Fig.3.
Dig a cavity for the foundation plate as shown in Fig. 4. The foundation
plate must be located as shown in Fig. 5 (right closing) or Fig.6 (left closing)
to ensure correct meshing between rack and pinion.
We advise you to place the plate on a cement base about 50 cm
off the ground (fig.7).
Lay the flexible pipes for routing the connection cables between gear-
motor, accessories and electrical power supply. The flexible pipes must
protrude by about 3 cm from the hole on the plate.

1) To lay cables, use adequate rigid and/or flexible tubes.
2) Always separate connection cables of low voltage accessories
from those operating at 230 V~. To prevent any interference wha-
tever, use separate sheaths.
