PRECAUTIONS
SEA operators have been created for the
automation of gates used by vehicles only. Be
aware to avoid the crossing of the gate path
because it is very dangerous for pedestrians
(fig.8).
Make sure that no person could activate the
automation or act on it from the outside (fig. 9)
WARNING SIGNS
Install the warning signs, on each side of the
gate and in a visible zone
which informs the
pedestrians about the danger they run when
passing or resting in the environment of the gate
Important:
For a higher security, SEA advices to install
infrared photocells

WARNING
Moving Gate Can Cause
Serious Injury Or Death
- KEEP CLEAR ! Gate may move at any
time without prior Warning.
- Do not let children operate the gate or
play in the gate area.
- This entrance is for vehicle only.
Pedestrians must use separate entrance
TYPE OF INSTALLATION
A front installation is the right and only
possible installation, it is highly recommended
to install two security gate stops on the two
extremities of the rail to prevent the gate from
derailment (fig. 11).
GATE ARRANGEMENT
The first thing to check is that the gate is in good running order as follows:
a)
The gate is rigid and straight and runs smoothly throughout its travel.
b)
That the inferior sliding guide-rail is perfectly straight and horizontal to avoid a derailment of the gate (fig. 1);
furthermore it must be free of irregularities and foreign bodies which could obstruct the normal run of the gate
(fig. 2 - 3).
c)
That the upper guides are not fixed (fig. 4) but furnished with rollers
d)
That the distance between the end of the gate (in maximum opening position) and the eventual wall must
be at least of 5 inches (fig. 7) which allow the sliding of the gate without difficulties (fig. 5 and 6).
e)
The lower support wheels have sealed bearings or grease points.
f)
The top guide must be manufactured and installed so that the gate is perfectly upright.
g)
Physical gate stops must be fitted to prevent the gate coming out of its guides and track.
