Preliminary checks
Before installing STONE check the following points:
- Make sure that the device operates within its limits of employment
described in the technical characteristics table.
- Make sure that the gate structure is sturdy and that the wing moves
without frictions or other impediments.
- Make sure that the device is undamaged.
- Don’t install the product in explosive environments.
- Perform all the structural changes in order to ensure safety
distances and protect and segregate areas in which people may be
exposed to the risk of crushing, shearing, dragging or similar
dangers.
- Foresee a free area destined to the operations of maintenance and
unblocking.
- For anything not expressly specified in this handbook, follow the
norms in force.
- Each wing must have just one hinge, remove any extra ones.
- Don’t install the device on blank wing gates, functioning cannot be
guaranteed in the presence of strong wind.
- For complete safety, the mechanical stops with rubber cap (floor
stops) must be fitted in opening and closing of the wing. They
delimit the extreme points of opening and closing of the wing.

Foundation box - Installation
- Dig a hole as per the measurements shown in fig.2. Foresee an
additional space for the pipes of water drainage and electric cables.
- Place the foundation box inside the hole so that the pin welded to
the box is aligned with the upper hinge of the gate (fig.3 and fig.4).
of water drainage- Insert the two pipes into the special holes fitted
on the box. Connect the pipes to a good canal of the rain
dispersion.
- Connect the tube of the electric cables into the special hole fitted on
the box, on the side of the wing opening.
- Cast the concrete inside the hole, making sure the box is level. It
must be 5 mm higher than the finished floor (cover thickness).
- Wait for the concrete has solidified.

Limit switches set up
Warning : for complete safety, the mechanical stops with rubber
cap (floor stops) must be fitted in opening and closing of the
gate in order to define the extreme points of the run.
Step-by-Step
- Connect the cable coming from the installation to the Limit switches
cable piece by means of heat shrinkable tubing (total insulation).
- Make sure that the gearmotor isn’t unlocked.
- Set up the “ ” operation mode on the electronic card.
- Start the gate run. As soon as the gate reaches the complete
opening, stop the gate by means of the remote control.
- With a screwdriver, move the magnet of the opening Limit switch
until the LED on the control unit goes off (fig. 13).
- Start the gate closing. As soon as the gate reaches the complete
closing, stop the gate by means of the remote control.
- With a screwdriver, move the magnet of the closing Limit switch
until the LED on the control unit goes off (fig. 13).

ELECTRIC CONNECTIONS
Warnings
- The gearmotor must be connected but to a control unit
manufactured by the company LEB.
- All connection operations must be performed without electric
voltage.
Power supply cable
- From the electric motor comes out four wires (230Vac - )
or two wires (24Vdc - STONE 24).
- In the following table the data concerning the power supply cable,
required for the connection to the control unit, are reported.

Limit switches cable
The device is equipped with two magnetic Limit switches. From the
Limit switches block three wires come out. In the following table the
data concerning the Limit switches cable, required for the connection
to the control board, are reported.
Manual unblocking
The manual unblocking causes the release of the device
from the wing, allowing the manual displacement of this one. It can be
used in case of electric voltage lack or of installation failure. The
unblocking is made through a key that is to be kept by user in a sure and
easily reachable place. In order to obtain the unblocking of the device,
proceed in the following way:
- Insert the socket spanner into the hole fitted on the traction arm (fig.17).
- Turn the socket spanner in the direction indicated in fig.17, then open the
wing of the gate by hand.
- To lock, bring the wing back to the hooking position with the traction arm.
- Turn the socket spanner in the opposite direction and simultaneously
push the wing to hook it.
