2 PRODUCT DESCRIPTION
AND INTENDED USE
This product is intended to be used to automate swing gates. CAU-
TION! – Any use other than the intended use, and any use in con-
ditions other than those described in this manual, is improper
and forbidden!
The product is an electromechanical gearmotor, available in two ver-
sions:
TO3000 / TO3024 and TO4500 / TO4524.
It is equipped with a 24V DC motor or 220V AC motor (depending on
the version) and a worm screw reduction unit.
The gearmotor is powered off the external control unit to which it is con-
nected.
In case of power outage, the gate can be operated manually by disen-
gaging the gearmotor (par. 3.4).

INSTALLATION

3.1 - Pre-installation checks

Caution! - The motor must be installed by qualified personnel in
compliance with current legislation, standards and regulations,
and the directions provided in this manual.
Before proceeding with the installation:
01. Check that the area to which the gearmotor is to be mounted is
large enough (fig. 2).
02. Check the gate's opening movement and the force exerted by the
motor: these depend on the position of the rear bracket. To set the
maximum opening of the gate and the motor force, refer to fig. 3.
03. Establish the rough installation position for each component of the
system and the most appropriate connection layout.

3.2 - Installation of gearmotor
WARNINGS
• Incorrect installation may cause serious physical injury to
those working on or using the system.
• Before proceeding with the installation, refer to par. 3.1.
01. Identify the front and rear bracket mounting positions (fig. 3)
02. Secure the rear bracket with reference to its specified installation
positions (fig. 3)
03. Mount the gearmotor to the rear bracket (fig. 5 / 6)
04. Manually release the gearmotor (fig. 7)
05. Pull the rod completely out (fig. 8 - a);
06. Provisionally locate the front bracket onto the gate (fig. 8 - b)
07. Check that the gearmotor is level, then fit and secure the rod to the
front bracket (fig. 8 - c);
08. (fig. 9) Check manually that:
- when the gate is fully open, it halts against its mechanical stops
- the gate swings freely and without resistance
Correct any defects
09. Unhook the rod from the front bracket (fig. 10 - a) and mount the
latter to the gate definitively (fig. 10 - b)
10. Definitively mount the rod to the front bracket (fig. 10 - c)

11. Lock the gearmotor (fig. 11)
Run this procedure for both gearmotors.
3.3 - Manually releasing the gearmotor (fig. 7)
01. Raise the rubber cap (fig. 7 - a)
02. Fit the provided wrench and rotate it CW by 90° (fig. 7 - b)
Run this procedure for both gearmotors.
3.4 - Manually locking the gearmotor (fig. 11)
01. Move the gate to the halfway open position by hand
02. Raise the rubber cap (fig. 11 - a)
03. Fit the provided wrench and rotate it CCW by 90° (fig. 11 - b)
Run this procedure for both gearmotors.
CAUTION!
– Incorrect connections can cause faults or hazards; therefore
ensure that the specified connections are strictly observed.
– Hook up the unit with the electrical power shut off.
01. Remove the gearmotor's cover (fig. 12 - a)
02. Loosen the cable clamp (fig. 12 - b) and run the cable through it(fig.
03. Hook up the cables and connect the earth cable to its eyebolt (fig.
04. Tighten down the cable clamp and restore the cover (fig. 14)
This is the most important stage in the automation system installation
procedure in order to ensure the maximum safety levels. Testing can
also be adopted as a method of periodically checking that all the various
devices in the system are functioning correctly.
Testing of the entire system must be performed by qualified and
experienced personnel who must establish which tests to conduct
on the basis of the risks involved, and verify the compliance of the sys-
tem with applicable regulations, legislation and standards, in particular
with all the provisions of EN12445 which establishes the test methods
for automation systems for gates.

5.1 - Testing

Each component of the system, (safety edges, photocells, emergency
stop, etc.) requires a specific testing phase. To do so, follow the pro-
cedures given in the instruction manuals.
01. Ensure that the instructions outlined in this manual and in particular
02. Manually release the gearmotor (fig. 7)
03. Make sure you can move the door manually both during opening
04. Manually lock the gearmotor (fig. 11)
05. Hook up the electrical power supply
06. Use the control or stop devices to test the opening, closing and
07. Check the operation of all safety devices, and check that the gate
08. Activate a closing manoeuvre and check impact force of the door
09. If the dangerous situations caused by the movement of the gate
Note – The gearmotor's torque cannot be adjusted directly: this
adjustment is done by the control unit.
