2.1 Applications
WG20 is a set of components designed for the automation of single-leaf
or double-leaf gates in residential applications.
Any applications other than those described above or under dif-
ferent conditions from those specified in this manual are forbid-
den.
WG20 operates with electric power. In the event of a power failure, the
gearmotor can be released using suitable keys in order to move the gate
manually. Alternatively, the PR1 buffer battery (optional accessory) can be
used.
2.2 Description of the automation

WG20 Instructions 5

2.3.3 CL20 Control Unit
2.3.4 PH1 Photocells
The CL20 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 CL20 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 sig-
nals its status.
The connection to the power supply is very easy: just insert the plug in a
power outlet.

WG20 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
WG20 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, WG20 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 mounting positions of the various devices are
protected from impacts and that the 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.
• Make sure there is enough space even when the gate is open.
• Using the leaf opening angle as a guideline, check that the
values in Table 6 can be met.
Figure 10
Figure 11
• "C" depends on how the rear bracket is mounted (see Figure 17) and
may vary from 53 mm to 176 mm. It is normally about 150mm.
• "D" is easy to measure on the gate.
• "A" is the sum of "C" and "D".
• The value of "B" can be calculated from the value of "A" and the
opening angle of the leaves. For example: if "A" is 150mm and the
opening angle of the leaves is 100°, the value of "B" is about 150mm.
Make sure that "B" is equal or similar to "A". This ensures the leaf moves
smoothly, thereby reducing the strain on the gearmotor.

Maximum leaf length (m)

8 WG20 Instructions
3.1.1 Operating Limits
Chapter 6 "Technical Characteristics" provides the fundamental data
needed to determine whether all the WG20 components are suitable for
the intended application.
In general, WG20 is suitable for the automation of gates featuring leaves
up to 4,5m wide, weighing up to 400 kg, with opening angle of up to
130° 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 WG20 gearmotor.
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 13.
3.1.3 List of Cables
The cables required for the installation of WG20 may vary depending on the type and quantity of devices to be installed; figure 14 shows the cables
needed for a typical installation; no cable is supplied with WG20.
Table 7: list of cables
Connection Cable type Maximum length allowed
[A] Power supply line 3x1.5mm2cable 30m (note 1)
[B] FLASH light output 2x0,5mm2cable 20m
[C] Radio aerial RG58 type shielded cable 20m (recommended less than 5m)
[D] ECSBus input/output 2x0,5mm2cable 20m (note 2)
[E] STOP input 2x0,5mm2cable 20m (note 2)
[F] OPEN input 2x0,5mm2cable 20m (note 2)
[G] M1 and M2 motors output 3x1mm2cable 10m
WARNING: the cables used must be suitable for the type of installation; for example, an H03VV-F type cable is recommended for indoor
applications, while H07RN-F is suitable for outdoor applications.
Note 1 A power supply cable longer than 30 m may be used provided it has a larger gauge, e.g. 3x2.5mm2, and that a safety grounding system
is provided near the automation unit.
Note 2 For the ESCbus, STOP and OPEN cables, there are no special contraindications to the use of a single cable that groups together multiple
connections; for example, the STOP and OPEN inputs can be connected to the KS1 selector switch using a single 4x0,5mm2cable.

1 Choose the mounting position in accordance with the specifications in
paragraph 3.1 "Preliminary Checks".
2 Check that the mounting surface is perfectly smooth, vertical and
sufficiently compact. WG10 does not come with a mounting system,
consequently one will have to be chosen according to the surface
material.
3 Lay the conduit for the power cable.
4 To obtain the rear supports, assemble two brackets and the rear plate
as shown in Figure 16.
5 To obtain different "C" values (see Figure 12) assemble the brackets and
plate as shown in Figure 17.
6 To obtain the front support, assemble two brackets and the front plate
as shown in Figure 18.
7 Remove the back cover of the gearmotors by sliding it in the direction
of the arrows.
8 Move the leaves to the "gate closed" position.
9 Referring to the "B" distance calculated from Table 6, place the rear
support in the correct position on the mounting surface, Check that there
is a suitable surface at the values in Figure 22, i.e. where the front
support is mounted.
10 Mark the drill points for the rear support using the support itself as a
reference point. Drill holes in the mounting surface for 4 anchors [A] with
a diameter of at least 8 mm (not included in supply). Fix the plate with
suitable screws [C] and washers [B].
WG20 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.
3.2 Preparing the Electrical System
Although the connection of WG20 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 WG20.
• The electric line must be grounded and protected against short
circuits; a bipolar disconnection device must also be present with
contact separation of at least 3 mm, which allows the power sup-
ply to be disconnected during the installation and maintenance of
the WG20.

11 Check that the plate is perfectly level, the slots on the bracket allow
small differences in alignment to be corrected.
12 Referring to Figure 22, place the front support at a distance of 820
mm from the rear support and 38 mm lower.
13 Temporarily fix the front support to the leaf with a clamp.
14 Lift up the gearmotor and fit the fork into the hole in the front support.
15 Keep the gearmotor lifted and pull it to open the gate until the hole in
the plate matches the hole in the gearmotor. Fix the gearmotor to the
rear support [E] with the screw [D], nut [G] and washer [F].
16 Firmly tighten the nut and then loosen it by about half a turn in order
to allow the gearmotor to rotate on the support.
17 Fix the gearmotor to the front support and anchor it with the screw [I]
and washer [H]. Fully tighten the screw.
18 Release the gearmotors using the appropriate release keys (see the
"Gearmotor Release" paragraph on page 34).
19 Test the mechanism by moving the gate by hand. Check that the fork
slides perfectly on the worm screw of the gear motor and that there
remains a margin of at least 5 mm from the opening and closing stops,
making sure, however, that not too much of the worm screw remains
unused.
20 If necessary, test the other assembly positions allowed by the front
and rear plates. See Figure 17.
21 If necessary, adjust the stops by loosening them with Allen keys [N]
and moving them to the required position. The opening stop [L] is used
if there are no opening stops on the ground. Normally, the leaves stop
against the closing stop during the closing manoeuvre. After adjusting
the stops, fully tighten the screws.
22 Secure the front support permanently using screws suited to the
material of which the gate is constructed.
23 Fix the gearmotor once more using the appropriate release keys (see
the "Gearmotor release" paragraph on page 34).
24 Thread the electrical cable through the conduit and bring it to the
control unit.
N.B.: the cable leaving the gear motor must be curved so that it can
follow the gearmotor when it rotates to open and close the leaf.

4 Drill a hole through the bottom of the control unit and use suitable
unions to fasten the conduits for the electric cables.
5 Breach the two bottom holes using a screwdriver, then mark the drilling
points using the bottom as reference.
6 Drill the holes in the wall using a hammer drill with a 6 mm bit and insert
the 6 mm screw anchors
7 Secure the bottom with the appropriate screws [A].

8 Refer to figure 49 for the electrical extra low voltage connection of the
various devices to the CL20 control unit terminals.
• The terminals have the same colour coding as the corresponding
devices; for example, the grey terminal (OPEN) of the KS1 selector
switch must be connected to the grey terminal (OPEN) of the control
unit.
• For most connections you do not need to observe any polarity; only
for the shielded cable of the aerial it is necessary to connect the central
core and the shield as shown in detail [B]. The cable for the motors must
be connected as shown in detail [A].
• Keep in mind that, to prevent the jamming of the two leaves, the
control unit commands the M2 motor to open first, followed by M1 (vice-
versa for the closing manoeuvre). Therefore make sure that the motor
that drives the leaf that strikes the mechanical stop is connected to
terminal M1 (outer one), while the motor that drives the other leaf must
be connected to terminal M2.
• If only one motor is used (single-leaf gate) it must be connected to
terminal M2 while terminal M1 remains free.

To facilitate the installation operations, the terminals [B] can be removed
as shown in figure 49; make the connections and then re-insert them.
When you have completed the connections, use clamps to secure the
cables to the appropriate fasteners [C].
9 To close the control unit you need to rest the cover on the bottom
approximately 3 cm above the final position, then press it down until it
snaps into place.

3.4 Power Supply Connection
3.5 Initial checks
The connection of the CL20 control unit to the mains must be
made by a qualified electrician.
To carry out tests, insert the plug for CL20 in a power outlet; if neces-
sary, use an extension cord.
The CL20 control unit must be permanently connected to the mains
power supply for the testing and commissioning operations.
This operation must be performed as follows by a qualified electrician:
1 Make sure that the plug of the CL20 control unit is not plugged into the
power socket
2 Disconnect the power cable from the CL20 control unit power supply
terminal
3 Slacken the collar close to the terminal and remove the cable
4 Insert the final power supply cable of the control unit through the collar
5 Connect the cable to the terminal of the control unit
6 Tighten the collar Figure 52
As soon as the CL20 control unit is energized, you should check the
following:
1 Make sure that the "ECSBus" LED [A] flashes regularly, with about one
flash per second.
2 Make sure that the SAFE LED [B] on the photocells flashes (both on TX
and RX); the type of flashing is not important as it depends on other factors;
what is important is that the LED should not be steadily on or steadily off.
3 Make sure that the night light [C] on the KS1 key-operated selector
switch is on.
4 If the above conditions are not satisfied, you should immediately switch
off the power supply to the CL20 control unit and check the cable
connections more carefully. For more useful information see also
chapters 5.5 "Troubleshooting" and 5.6 "Diagnostics and Signals".

3.5.1 Recognition of Connected Devices
When you have completed the initial checks, the control unit must
recognize the devices connected to it on the "ECSBus" and "STOP"
terminals.
1 On the control unit, press the P2 button [C] and hold it down for at
least three seconds, then release the button.
2 Wait a few seconds for the control unit to finish recognizing the
devices.
3 When the learning procedure is completed, the STOP LED [A] must
remain on, while the P2 LED [B] must go off. If the P2 LED flashes it
means that an error has occurred: see paragraph 5.5 "Troubleshooting".
The connected devices recognition stage can be repeated again at any
time, even after the installation (for example, if an additional photocell is
installed); just repeat the procedure starting from step 1.

16 WG20 Instructions
3.5.3 Checking the Radio Transmitters
After recognizing the devices, the control unit must learn to recognize the
leaves' opening and closing angles .
During this stage, the leaves' opening angle is measured from the
closing mechanical stop to the opening mechanical stop.
Fixed and sufficiently sturdy mechanical stops are required.
1 Release the motors using the appropriate keys (see the "Gearmotor
Release" paragraph on page 34) and move the leaves to mid travel so
that they are free to move in both opening and closing directions; then
lock the motors.
2 On the control unit press the P3 button [B] and hold it down for at least
three seconds, then release the button.
Wait for the control unit to complete the recognition stage: closing of the
M1 motor to the mechanical stop, closing of the M2 motor to the
mechanical stop, opening of the M2 and M1 motors to the opening
mechanical stop; complete closing of M1 and M2.
• If the first manoeuvre of one or both leaves is not to close, press P3
to interrupt the recognition stage, then switch the polarity of the motor/s
that opened by exchanging the two brown and blue wires on the
terminal.
• If the first motor to move in the closing direction is not M1, press P3
to interrupt the recognition stage, then switch the motor connections on
the terminals.
• If any device is triggered during the recognition stage (photocells, key-
operated selector switch, pressure on P3, etc.), the recognition stage will
immediately be interrupted. It will therefore be necessary to start again
from the beginning.
3 If at the conclusion of the search the P3 LED [A] flashes, it means that
an error has occurred; see paragraph 5.5 "Troubleshooting".
The opening angles recognition stage can be repeated again at any time,
even after the installation (for example, if one of the opening stops is
moved); just repeat the procedure starting from step 1.
3.5.2 Recognition of Gate Leaves' Opening and Closing Angles
Figure 57
B
A
To check the transmitters just press one of the four buttons, make sure
that the red LED flashes and that the automation executes the
command.
The command associated to each button depends on how they have
been memorized (see paragraph 5.4 "Memorization of Radio
Transmitters"). The transmitters supplied have already been memorized
and when you press the buttons the following commands are
transmitted:
Button T1 "OPEN" command
Button T2 "Open pedestrian gate" command
Button T3 "Open only" command
Button T4 "Close only" command
3.6 Regulations
3.6.1 Selecting the Speed of the Leaf
The leaves can be opened and closed at two speeds: "slow" or "fast".
To switch from one speed to the other press the P2 button [B]
momentarily; the corresponding P2 LED [A] will light up or go off; if the
LED is off the speed is "slow", if the LED is on the speed is "fast".

1 Make sure that the provisions contained in chapter 1
"WARNINGS" have been carefully observed.
2 Using the selector switch or the radio transmitter, test the opening and
closing of the gate and make sure that the leaves move in the intended
direction.
The test should be carried out a number of times to make sure that the
gate moves smoothly, that there are no points of excessive friction and
that there are no defects in the assembly or adjustments.
3 Check the proper operation of all the safety devices, one by one
(photocells, sensitive edges, etc.). In particular, each time a device is
activated the "ECSBus" LED on the control unit flashes for a longer time,
confirming that the control unit recognizes the event.
4 To check the photocells and make sure that there is no interference
with other devices, pass a 5 cm diameter, 30 cm long cylinder on the
optical axis, first near TX, then near RX and finally at the mid-point
between them and make sure that in all these cases the device is
triggered, switching from the active to the alarm status and vice-versa;
finally, that it causes the intended action in the control unit, for example
that it causes the reversal of the movement during the closing
manoeuvre.
5 Measure the impact force according to EN 12445 standard. If "motor
force" control is used to assist the system for the reduction of the impact
force, try to find the adjustment that gives the best results.
3.6.2 Selecting the Type of Operating Cycle
The opening and closing of the gate can take place according to different
operating cycles:
• Single cycle (semiautomatic): the gate opens with a command and
stays open until the next command is given, causing it to close.
• Complete cycle (automatic closing): the gate opens with a command
and then closes automatically after a short time (for the time, see
paragraph 5.1.1 "Adjusting the Parameters with the Radio Transmitter").
To switch from one operating cycle to the other, press the P3 button [B]
momentarily; the corresponding LED [A] will light up or go off; if the LED
is off the cycle is "single", if the LED is on the cycle is "complete".

3.7 Testing and commissioning
These are the most important operations, designed to guarantee the
maximum safety and reliability of the automation system.
The testing procedure can also be used as a periodic check of the
devices that make up the automation.
The testing and commissioning operations must be performed by
qualified and experienced personnel who must establish what
tests should be conducted based on the risks involved, and verify
the compliance of the system with applicable regulations,
legislation and standards, in particular with all the provisions of
EN 12445 standard which establishes the test methods for gate
automation systems.
3.7.1 Testing
3.7.2 Commissioning
Figure 61
The commissioning operations can be performed only after all
the tests have been successfully carried out. Partial
commissioning or implementation of "temporary" conditions are
not permitted.
1 Prepare the technical documentation for the automation, which must
include at least: assembly drawing (e.g. figure 1), wiring diagram (e.g.
figure 14), analysis of hazards and solutions adopted, manufacturer's
declaration of conformity of all the devices installed. For WG20 use
Annexe 1 "EC Declaration of Conformity of the WG20 components".
2 Post a label on the gate providing at least the following data: type of
automation, name and address of manufacturer (person responsible for
the "commissioning"), serial number, year of manufacture and "CE"
marking.
3 Fill out the declaration of conformity and deliver it to the owner of the
automation system; for this purpose you can use Annexe 2 "EC
Declaration of Conformity".
4 Prepare the operating guide and deliver it to the owner of the
automation system; Annexe 3 "OPERATING GUIDE" can be used as an
example.
5 Prepare the maintenance schedule and deliver it to the owner of the
automation system; it must provide directions regarding the
maintenance of all the automation devices.
6 Before commissioning the automation system inform the owner
regarding dangers and hazards that are still existing.

18 WG20 Instructions
The maintenance operations must be performed in strict
compliance with the safety directions provided in this manual and
according to the applicable legislation and standards.
The devices used for the WG20 automation system do not require any
special maintenance. However, periodically make sure (at least once
every six months) that all the devices are perfectly efficient. To this end,
carry out all the tests and checks described in paragraph 3.7.1 "Testing"
and the operations described in paragraph 7.3.3 "Maintenance
Operations to Be Performed by the User".
If other devices are present, follow the directions provided in the
corresponding maintenance schedule.
4 Maintenance
4.1 Dismantling and Disposal
WG20 is constructed of various types of materials, some of which can
be recycled (aluminium, plastic, electric cables), while others must be
disposed of (electronic boards).
WARNING: some electronic components may contain polluting
substances; do not pollute the environment. Enquire about the
recycling or disposal systems available for WG20 in compliance
with regulations locally in force.
1 Contact a qualified electrician regarding the disconnection of the
automation system from the electric mains.
2 Disassemble all the devices and accessories, following in reverse order
the procedures described in chapter 3 "Installation".
3 Remove the batteries from the radio transmitters.
4 Remove the electronic boards.
5 Sort the various electrical and recyclable materials and consign them
to licensed firms for recovery and disposal.
6 Consign the remaining materials to authorized scrap collection centres.

WG20 Instructions 19
The radio transmitter can be used to adjust certain control unit operation
parameters: there are four parameters and each of them can have four
different values:
1) Pause time: time during which the leaves remain open (in the
automatic closing mode).
2) Pedestrian gate: pedestrian gate opening mode.
3) Motor force: maximum force beyond which the control unit recognizes
an obstacle and reverses the movement.
4) "OPEN" function: sequence of movements associated to each
"OPEN" command.
The following chapters describe different ways of customizing WG20 to
make it suitable for specific application requirements.

The parameter adjustment operation can be performed using any of the
radio transmitters, provided they are memorized in mode 1 like the ones
supplied (see paragraph 5.4.1 "Mode 1 memorization").
In the event that no transmitter memorized in Mode 1 is available, it is
possible to memorize one just for this stage and delete it immediately
afterwards (see paragraph 5.4.4 "Deleting a radio transmitter").
WARNING: when using the transmitter to make adjustments you need
to give the control unit time to recognize the radio command; this means
that the buttons must be pressed and released slowly, held down for at
least one second, then released for one second and so on.
1 Press buttons T1 and T2 on the radio transmitter simultaneously for at
least 5s.
2 Release the two buttons.
3 Within 3 seconds, perform the action described in Table 8 based on
the parameter to be modified
Example: to set the pause time at 40 s.
1st Press buttons T1 and T2 and hold them down for at least 5s
2nd Release T1 and T2
3rd Press button T1 three times
All the parameters can be adjusted as required without any
contraindication; only the adjustment of the "motor force" requires
special care:
• Do not use high force values to compensate for points of abnormal
friction on the gate. Excessive force can compromise the operation of
the safety system or damage the leaf.
• If the "motor force" control is used to assist the impact force reduction
system, measure the force again after each adjustment in compliance
with EN 12445 standard.
• The weather conditions may affect the movement of the leaf, therefore
periodic re-adjustments may be necessary.
Figure 62

20 WG20 Instructions
With a radio transmitter memorized in mode 1, the adjustment values for
each parameter can be checked at any time using the following
sequence:
1 Press buttons T1 and T2 on the radio transmitter simultaneously for at
least 5s.
2 Release the two buttons.
3 Within 3 seconds, perform the action described in Table 9 based on
the parameter to be checked.
4 Release the button when the flashing light starts flashing.
5 Count the flashes and, based on their number, check the
corresponding value in Table 8.
Example. If the flashing light flashes three times after you have pressed
T1 and T2 for 5s and then button T1, the pause time is set at 40s.

5.2 Optional Accessories
In addition to the devices featured in WG20, other ones are available as
optional accessories designed to enhance the automation system.
PR1: 24V buffer battery for supply in the event of power failure. It guar-
antees at last 5 complete cycles. When the system is powered by the
battery, the manoeuvre takes place only in "slow" speed mode.
PT50: Pair of 500 mm posts with one photocell
PT100: Pair of 1000 mm posts with two photocells
For information on the new accessories, refer to the MHOUSE catalogue
or visit the site www.mhouse.biz.
5.3 Adding or Removing Devices
Devices can be added to or removed from the WG20 automation sys-
tem at any time.
Do not add any devices until you have made sure that they are
perfectly compatible with WG20; for further information contact
MHOUSE Customer Service.
5.3.1 ECSBus
ECSBus is a system that allows you to connect the ECSBus devices
using only two wires which carry both the power supply and the com-
munication signals. All the devices are connected in parallel on the 2
wires of the ECSBus itself; each device is individually recognized
because a univocal address is assigned to it during the installation.
The photocells, as well as other devices that adopt this system, can be
connected to ECSBus, such as safety devices, control buttons, sig-
nalling lights etc. For information on the ECSBus devices, refer to the
MHOUSE catalogue or visit the site www.mhouse.biz.
The CL20 control unit recognizes to recognize all the connected devices
individually through a suitable recognition process, and can detect all the
possible abnormalities with absolute precision. For this reason, each
time a device connected to ECSBus is added or removed the control
unit must go through the recognition process; see paragraph 5.3.3
"Recognition of Other Devices".
5.3.2 STOP Input
STOP is the input that causes the immediate interruption of the
manoeuvre (with a short reverse run). Devices with output featuring
normally open "NO" contacts (like the KS1 selector switch) and devices
with normally closed "NC" contacts, as well as devices with 8.2KΩ
constant resistance output, like sensitive edges, can be connected to
this input.
Multiple devices, even of different type, can be connected to the STOP
input if suitable arrangements are made.
To do this, proceed as described in the following table:
Note 1. The NO and NC combination can be obtained by placing the two
contacts in parallel, and placing in series to the NC contact an 8.2KΩ
resistance (therefore, the combination of 3 devices is also possible: NO,
NC and 8.2KΩ).
Note 2. Any number of NO devices can be connected to each other in
parallel.
Note 3. Any number of NC devices can be connected to each other in
series.
Note 4. Only two devices with 8.2KΩconstant resistance output can be
connected in parallel; if needed, multiple devices must be connected "in
cascade" with a single 8.2KΩtermination resistance.
Warning: if the STOP input is used to connect devices with safety
functions, only the devices with 8.2KΩconstant resistance output
guarantee the fail-safe category 3.
During the recognition stage the control unit, like ECSBus, recognizes
the type of device connected to the STOP input; subsequently it
commands a STOP whenever a change occurs in the learned status.

WG20 Instructions 21
Normally the recognition of the devices connected to the ECSBus and
the STOP input takes place during the installation stage. However, if new
devices are added or old ones removed, the learning process can be
gone through again by proceeding as follows:
1 On the control unit, press the P2 [B] button and hold it down for at least
three seconds, then release it.
2 Wait a few seconds for the control unit to finish recognizing the
devices.
3 When the recognition stage is completed the P2 LED [A] should go off.
If the P2 LED flashes it means that something is wrong; see paragraph
5.5 "Troubleshooting".
4 After you have added or removed any devices, the automation system
must be tested again according to the directions contained in paragraph
3.7.1 "Testing".

Figure 63
5.3.4 Addition of Optional Photocells
Additional photocells can be installed at any time on top of those
supplied with WG20. In an automation system for 2-leaf gates these can
be arranged as shown in Figure 64.
To ensure the correct recognition of the photocells by the control unit, the
former must be assigned addresses by means of jumpers. The address
allocation procedure must be performed on TX as well as RX (arranging the
jumpers in the same manner), but you must make sure that there are no other
pairs of photocells having the same address.
The photocells need to be assigned addresses to make sure that they are
correctly recognized among the other ECSBus devices, and in order to
assign the performed function.
1 Open the shell of the photocell.
2 Identify the position where they are installed based on figure 64 and
connect with jumper according to Table 11.
The unused jumpers must be stored in their proper compartment for
future use (Figure 65).
3 Perform the recognition stage as explained in paragraph 5.3.3
"Recognition of other devices".

22 WG20 Instructions
The CL20 control unit contains a radio receiver for TX4 transmitters;
those included in the package are pre-memorized and operative.
If you wish to memorize a new radio transmitter you have two choices:
• Mode 1: in this "mode" the radio transmitter is used to its fullest extent,
i.e. all the buttons execute a pre-established command (the transmitters
supplied with WG20 are memorized in Mode 1). It is obvious that in
Mode 1 a radio transmitter can be used to command a single
automation, i.e.:
• Mode 2: one of the four commands available can be associated to
each button. This mode, used properly, allows you to command 2 or
more different automations; for example:
Each transmitter is, of course, a separate unit, and while some are
memorized in mode 1 others can be memorized in mode 2 on the
control unit.
The overall memory capacity is 150 units; memorization in mode 1 takes up
one unit for each transmitter while mode 2 takes up one unit for each button.
Warning: since the memorization procedures are timed (10s), you
must read the instructions in the following paragraph before you
proceed with their execution.
T1 button "OPEN" command
T2 button "Pedestrian gate" command
T3 button "Open only" command
T4 button "Close only" command
5.4 Memorization of Radio Transmitters
5.4.1 Memorization Mode 1
1 Press button P1 [B] for at least 3 s.. When the P1 LED [A] goes off,
release the button.
2 Within 10s, press any button on the radio transmitter to be memorized
and hold it down for at least 3s.
If the memorization procedure is successful, the "P1" LED will flash 3
times.
3 If there are other transmitters to be memorized, repeat step 2 within
the next 10s, otherwise the memorization stage will terminate
automatically.
Figure 66
5.4.2 Memorization Mode 2
With the memorization in mode 2 of the radio transmitter, any one of the
four commands ("OPEN", "Open partially", "Open only" and "Close only")
can be associated to each button.
In Mode 2 each button requires a separate memorization stage.
1 Delete the remote control system by following procedure "5.4.4
Deleting a radio transmitter."
2 Press button P1 (figure 66) on the control unit as many times as the
number corresponding to the desired command, according to the
following table: (e.g. 3 times for the "Open only" command).
3 Make sure that the P1 LED makes as many quick flashes as the
number corresponding to the selected command.
4 Within 10 s, press the desired button on the radio transmitter to be
memorized, and hold it down for at least 2 s.
If the memorization procedure is successful, the "P1" LED will flash 3
times slowly.
5 If there are other transmitters to be memorized for the same type of
command, repeat step 3 within the next 10s, otherwise the
memorization stage will terminate automatically.

A new radio transmitter can be memorized in the control unit without
directly operating the buttons on it. You need to have an "OLD" pre-
memorized operational radio transmitter. The "NEW" radio transmitter to
be memorized will inherit the characteristics of the OLD one, i.e. if the
OLD radio transmitter was memorized in Mode 1, the NEW one will also
be memorized in Mode 1. In this case, during the memorization stage
you can press any key on the two transmitters. If, on the other hand, the
OLD transmitter was memorized in Mode 2 you must press the button
on the OLD transmitter which corresponds to the desired command,
and the button on the NEW transmitter to which you wish to associate
that command.
Holding the two transmitters, position yourself within the operating range
of the automation and perform the following operations:
1 Press the button on the NEW radio transmitter and hold it down for at
least 5s, then release it.
2 Press the button on the OLD radio transmitter 3 times slowly.
3 Press the button on the NEW radio transmitter once slowly.
At this point the NEW radio transmitter will be recognized by the control
unit and will assume the characteristics of the OLD one.
If there are other transmitters to be memorized, repeat all the steps
above for each new transmitter.

WG20 Instructions 23
5.4.5 Deleting all the Radio Transmitters
With this operation all the memorized transmitters are deleted.
1 Press the P1 button [B] on the control unit and hold it down.
2 Wait until the P1 LED [A] lights up, then wait until it goes off, than wait
until it has flashed 3 times.
3 Release the P1 button precisely upon the third flash.
4 Wait approximately 4s for the deletion process to be completed; during
this time the LED will flash very quickly.
If the procedure is successful, after a few moments the "P1" LED will
flash slowly 5 times. Figure 67

5.5 Troubleshooting
The following table contains instructions to help you solve malfunctions or errors that may occur during the installation stage or in case of failure.
Table 12
Symptoms Probable cause and possible solution
The radio transmitter does not emit any
signal (the LED [A] does not light up) • Check to see if the batteries are exhausted, if necessary replace them (page 34)
The manoeuvre does not start and the
"ECSBbus" LED [B] does not flash
• Make sure that the power cord is properly plugged into the mains outlet
• Check to see if the fuses [E] or [F] are blown; if necessary, identify the reason for the failure and then replace
the fuses with others having the same current rating and characteristics..
The manoeuvre does not start and the
flashing light is off
• Make sure that the command is actually received. If the command reaches the OPEN input, the
corresponding "OPEN" LED [D] must light up; if you are using the radio transmitter, the "ECSBus" LED must
make two long flashes.
The manoeuvre does not start and the
flashing light flashes a few times
• Make sure that the STOP input is active, i.e. that the "STOP" LED [C] comes on. If this does not happen,
check the devices connected to the STOP input.·
• The photocell test which is performed at the starting of each manoeuvre is not successful; check the
photocells, also according to Table 13 on page 24.
The manoeuvre starts but it is immediately
followed by a reverse run
• The selected force is too low to move the leaves. Check to see whether there are any obstacles; if
necessary increase the force as described on page 19.
The manoeuvre is carried out but the
flashing light does not work
• Make sure that there is voltage on the flashing light's FLASH terminal during the manoeuvre (being
intermittent, the voltage value is not important: approximately 10-30Vac); if there is voltage, the problem is
due to the lamp; in this case replace the lamp with one having the same characteristics.

5.4.4 Deleting a Radio Transmitter
If a radio transmitter is available, this operation allows you to delete it.
If the transmitter is memorized in Mode 1, a single deletion stage is
sufficient: just press any button at point 3. If the transmitter is memorized
in Mode 2, one deletion stage is needed for each memorized button.

• Keep at a safe distance while the gate is moving; do not pass
through until the gate has opened all the way and the leaves have
stopped moving.
• Do not allow children to play near the gate or with its controls.
• Stop using the automation system immediately if you notice
anything abnormal (strange noise or jerky movements); failure to
observe this warning may result in serious danger and accidents.
• Do not touch any components while they are moving.
• Have periodic checks made according to the instructions
provided in the maintenance schedule.
• Maintenance operations and repairs can only be performed
by qualified technicians.
This guide should be stored in an accessible location and made available
to all users of the automation.
7.3 Annexe 3: Operating Guide
7.3.1 Safety regulations
With radio transmitter
The radio transmitter is ready for use and the four buttons have the
following functions:
With selector switch
The selector switch has two positions, with automatic return to the centre.
Control with safety devices out of order
If the safety devices are out of order or malfunctioning, it is still possible
to control the gate.
1 Operate the gate control device (remote control or key-operated
selector switch). If the safety devices enable the operation, the gate will
open normally, otherwise:
2 The flashing light flashes a few times but the manoeuvre does not start
(the number of flashes depends on the reason why the manoeuvre is not
enabled).
3 In this case, actuate the control again within 3 seconds and keep it
actuated.
4 After approximately 2s the gate will start moving in the "man present"
mode, i.e. so long as the control is maintained the gate will keep moving;
as soon as the control is released the gate will stop.
If the safety devices are out of order the automation must be repaired as
soon as possible.

34 WG20 Instructions
Gearmotor release
The gearmotor is equipped with a mechanical system which allows the
gate to be opened and closed manually (i.e. as if WG20 were not present).
The manual operation must be resorted to in case o power failures or
system malfunctions. If a power failure occurs, the buffer battery can be
used (PR1 optional accessory).
If there is a malfunction of the gearmotor it is still possible to try and
release the motor in order to check whether the problem is connected
with the release mechanism.
1 Turn the release mechanism cover clockwise until the hole matches the
release pin.
2 Insert the key in the pin.
3 Turn the key anti-clockwise.
4 At this point, the gate leaf can be moved manually.
5 To restore the functionality of the automation system, rotate the lever
clockwise while simultaneously moving the leaf until it is caught by the
mechanism.
6 Remove the key and close the cover by turning it anti-clockwise.
The only maintenance operations that the user can and must perform
periodically concern the cleaning of the photocell glasses and the
removal of leaves and debris that may impede the automation.
• Use a slightly damp cloth (not wet) to clean the surface of the
devices. Do not use any substances containing alcohol, benzene,
diluents or other flammable substances. The use of these
substances could damage the devices, start fires or generate
electric shocks.
• Disconnect the power supply to the automation before you
proceed to remove leaves and debris, to prevent anyone from
activating the gate.
If the range of the remote control is significantly diminished and the light
emitted by the LED is feeble, the remote control battery is probably
exhausted. The remote control houses to CR2016 type lithium batteries.
To replace them proceed as follows:
1 Open the bottom by pulling it.
2 Insert a small pointed tool in the slit and prise the batteries out.
3 Insert the new battery, observing the polarity (the "+" symbol towards
the bottom ).
4 Close the bottom until it clicks.
The batteries contain polluting substances: do not dispose of
them together with other waste but use the methods established
by local regulations.
