WU1 is an electromechanical gearmotor consisting of a helical teeth
reduction gear and a 24Vdirect current motor. It features a key-operated
mechanical release mechanism that allows you to move the gate
manually in the event of a power failure. The gearmotors can be
mounted on the ground under the gate (if there is a clearance of at least
90mm), or they can be mounted underground using the special
foundation plates.

The slotted arm and the related mounting bracket enable the connection
between the gearmotor and the gate leaf.

2.3.3 CL2 Control Unit

2.3.4 PH1 Photocells

The CL2 unit actuates the gearmotors and provides for the control and
supply of the different components; it features an electronic board with
incorporated radio receiver; a housing [B] for the PR1 buffer battery
(optional), which is necessary for operation in case of power failure.

The CL2 control unit can actuate the gearmotors with two speeds:
"slow" and "fast".

The three P1, P2 and P3 buttons [C] and the corresponding LED's are
used to program the control unit.

To facilitate the electrical connections there are separate terminals for
each device [A], which are removable and colour-coded based on the
function performed. Next to each input terminal there is a LED that
signals its status.

The connection to the power supply is very easy: just insert the plug in a
power outlet.

WU2 Instructions 7

The installation must be carried out by qualified and skilled
personnel in compliance with the directions provided in chapter
1 "WARNINGS".

3 Installation

3.1 Preliminary Checks

WU2 must not be used to power a gate that is not efficient and
safe. It cannot solve defects resulting from incorrect installation
or poor maintenance of the gate.

Before proceeding with the installation you must:

• Make sure that the weight and dimensions of the gate fall within
the specified operating limits. If they do not, WU2 cannot be used.

• Make sure that the structure of the gate is suitable for
automation and in compliance with regulations in force.

• Make sure that there are no points of greater friction in the
opening or closing travel of the gate leaves.

• Make sure that the gate is well balanced: it must not move by
itself when it is placed in any position.

• Make sure that the location where the gearmotor is installed is
compatible with the overall dimensions of the gearmotor and that
it allows the release manoeuvre to be carried out easily and
safely.

• Make sure that the mounting positions of the various devices
are protected from impacts and that the mounting surfaces are
sufficiently sturdy.

• Make sure that the mounting surfaces of the photocells are flat
and that they enable the proper alignment between TX and RX.

• Check the size limits referring to Figure 10, Figure 11, Figure 12
and according to the type of installation: with gearmotor installed
underground or surface mounted.

Table 6: (measurements in millimetres)

A B C

1st choice 0 from 0 to 80 from 160 to 170

2nd choice from 10 to 30 from 0 to 80 from 180 to 190

3rd choice from 31 to 50 from 0 to 70 from 200 to 210

4th choice from 51 to 60 from 0 to 60 from 210 to 240

Measurement "A" is the most important: if possible, choose the 1st line;
once "A" has been established, you can calculate the minimum and
maximum values of "B" and "C" using the table.

An opening angle of at least 100° of the gate leaves is guaranteed in all
cases. If you want a wider angle, up to 120°, you must choose the low
values of measurement "B" and the minimum value of "C".

Figure 11

Figure 13

Figure 12

Figure 10

3.1.1 Operating Limits

Chapter 6 "Technical Characteristics" provides the fundamental data
needed to determine whether all the WU2 components are suitable for
the intended application.

In general, WU2 is suitable for the automation of gates featuring leaves
up to 1.8 m wide, weighing up to 200 kg, with opening angle of up to
120° for residential applications.

The shape of the gate and the climatic conditions (e.g. presence of
strong wind) may reduce these maximum limits. In this case it is
necessary to measure the torque needed to move the leaves under the
worst conditions, and to compare it to the data provided in the technical
characteristics chart for the WU1 gearmotor.

• Whether the WU1 gearmotor is underground or surface
mounted, the measurements shown in Table 6 must be observed:

3.1.2 Tools and Materials

Make sure you have all the tools and materials needed to install
the system; make sure that they are in good condition and
serviceable according to current safety standards. See examples
in Figure 14.

3.1.3 List of Cables

The cables required for the installation of WU2 may vary depending on the type and quantity of devices to be installed; Figure 15 shows the cables

WU2 Instructions 9

With the exception of the power line that supplies the control unit, the
rest of the system uses extra-low voltage (approx. 24V); the wiring can
therefore be done by personnel that is not properly qualified, provided
that all the instructions in this manual are carefully observed.

After selecting the position of the various devices (refer to Figure 1) you
can start preparing the conduits for the electrical cables connecting the
devices to the control unit.

The conduits are designed to protect the electrical cables and prevent
accidental breakage, which may be caused by the passage of vehicles,
for instance.

Although the connection of WU2 to the electrical mains is beyond the
scope of this manual, we wish to remind you that:

•The power supply line must be laid and connected by a
qualified professional electrician.

• Alternatively, have a suitably protected 16A "shuko" outlet
installed, where you can plug in WU2.

• The power supply line must be protected from short circuits
and ground leakage; a device must be provided to enable the
disconnection of the power supply during the installation and
maintenance of WU2 (the plug with outlet are suitable for this
purpose).

3.2 Preparing the Electrical System

There are two installation possibilities for the WU1 gearmotors:

A) Underground installation (see paragraph 3.3.1)

B) Surface installation (see paragraph 3.3.2)

If installation of the gearmotor under the gate leaf is problematic, we
recommend that you remove the leaf.

3.3 Installation of the Various Devices

3.3.1 Underground Mounting of Gearmotors

1 Dig a foundation hole, observing the instructions in paragraph 3.1
"Preliminary Checks", particularly measurements "A"and "B" shown in
Table 6.

2 Lay the conduit for the power cable.

3 Separate the motor from the foundation plate.

4 Insert the four studs [B] in the foundation plate, securing them above
and underneath with two M8 nuts [A] and [C]; observe the maximum
