INSTALLATION

STEP 3

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

3.1 – PRELIMINARY CHECKS

GD0 must not be used to power a door that is not efficient and safe.
It cannot solve defects resulting from incorrect installation or poor
maintenance of the door.

WARNING: incorrect installation could cause serious damage.

Before proceeding with the installation you must:

• Make sure that the door movement does not hinder roads or public
footpaths.

• After the motor has been installed, remove unnecessary cables or
chains and turn off any unneeded equipment

• Make sure that the weight and dimensions of the door fall within
the specified operating limits (Chapter 3.1.1). If they do not, GD0
cannot be used.

• Make sure that the structure of the door 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 door.

• Make sure that the mechanical structure of the door is sturdy
enough and that there is no risk of derailing out of the guide.

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

• Make sure that the installation area is compatible with the size of
the gearmotor and that it is safe and easy to release it.

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

8

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

• Make sure that the minimum and maximum clearances specified in
fig. 8 are observed.

• Pay attention in particular to the methods for securing the head of
the guide and the brackets to the ceiling. The head of the guide will
have to bear all the strain of opening and closing the door; the ceil­ing-mounted brackets will have to bear all the weight of GD0. In both
cases, the wear and deformations that may occur in time must be
taken into consideration.

• The gearmotor should be mounted so that it coincides with the
centre of the door, or is slightly off-centre, e.g. in order to mount the
OSCILLATING ARM next to the handle (Figure 9).

• Make sure that, in the position corresponding to the door, or slight­ly to the side, (see positions “A” and “B”) the conditions are suitable
for mounting the head of the guide; in particular, the material should
be sufficiently sturdy and compact.

Make sure that GD0 can be mounted on the ceiling along position
“C” using the mounting brackets.

If the door to be automated is an overhead type with springs or
counterweights, it will be necessary to install an OSCILLATING ARM,
which must be mounted next to the handle (Figure 9).

• Make sure that distance [E] in Figure 10, i.e. the minimum distance
between the upper side of the guide and the maximum point
reached by the upper edge of the door, is no shorter than 65 mm and
no longer than 300 mm, otherwise GD0 cannot be installed.

If the door closes a room that has no other means of access, we rec­ommend installation of the EXTERNAL RELEASE KIT, otherwise a
simple power failure will prevent access to the room (figure 11 and
11a).

Note: the oscillating arm and external release kit are supplied with
the related assembly instructions.

3.1.1 – Operating limits

Chapter 6 “Technical Characteristics” provides the fundamental data
needed to determine whether all the GD0 components are suitable for the
intended application.

In general GD0 is suitable for the automation of sectional and overhead
doors for residential applications having the following maximum dimen­sions:

Sectional doors: 240 cm max. height - 370cm (8.8m2) max. width - max­imum torque 55 kg.

Overhead garage doors non-protruding: 220 cm max. height - 350 cm
(7.7m2) max. width - maximum torque 55 kg.

12

Overhead garage doors protruding: 280 cm max. height - 350 cm (9.8m2)
max. width - maximum torque 55 kg.

The shape of the door and the climatic conditions (e.g. presence of strong
wind) may reduce this maximum limit. In this case it is necessary to meas­ure the torque needed to move the door under the worst conditions, and
to compare it to the data provided in the technical characteristics chart for
the GD0 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 12.

3.2 – PREPARING THE ELECTRICAL SYSTEM

With the exception of the plug and the power cable, 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 13) you
can start preparing the conduits for the electrical cables connecting the
devices to the control unit.
The shock-resistant conduits are designed to protect the electrical cables
and prevent accidental breakage.
Install any fixed control close to the door but away from moving parts and
at a height of 1.5m.

3.2.1 – Connection to the Electrical Mains

Although the connection of GD0 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.

• Have a suitably protected 16A “schuko” outlet installed, where you
can plug in GD0.

• Make sure that the power supply cable does not hang over moving
parts or hazardous areas.

• 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 3mm, which allows the power supply to be
disconnected during the installation and maintenance of the GD0.

3.3 – INSTALLATION OF THE VARIOUS DEVICES

The GD0 installation is made up of three parts:

- Guide assembly (see paragraph 3.3.1).

- Fixing of the gearmotor to the guide (see paragraph 3.3.2).

- Fixing of the gearmotor to the ceiling (see paragraph 3.3.3).

3.3.1 – Guide assembly

The guide supplied with the GD0 must be assembled as follows:

1. Referring to figure 14, remove the belt tensioner device (14a); insert

one end of the belt into the pulley (14b); reintroduce the belt tensioner
device into the guide (14c).

2. Pass the same end of the belt through the head (B), as in figure 15.

Note – Make sure that the belt is correctly positioned: it must be with the
teeth facing inwards, straight and without twists.

3. Turn the lower section of the carriage so that the grooves correspond

with the two ends of the belt, as in figure 16.

4. Position both ends of the belt into all of the shaped slots of the lower

carriage (C). Secure the ends of the belt with the 2 screws (V4.2x9.5)
and 2 washers (R05), as in figure 17.

5. Fix the belt guide (D) to the upper carriage (E) with the V6x18 screw

and related M6 nut, as in figure 18.

6. Insert the upper carriage (E)into the lower carriage (C) and place the

entire carriage assembly inside the guide, as in figure 19.

14a

With the door closed, pull the cord and release the carriage [E] from

the guide.

8 Slide the carriage until the door mounted bracket [D] shown in Fig-

ure 32 is positioned on the upper edge of the door, exactly perpendi­cular to the guide [G].

Next, secure the door mounted bracket [D] with screws or rivets. Use
screws or rivets that are suitable for the door material, making sure
that they are capable of bearing all the strain resulting from opening
and closing the door.

The gearmotor can be rotated in three different positions

3.3.3 – Fixing of the gearmotor to the ceiling

1 Observing the A, B and C positions shown in Figure 8, mark the 2 fas-

tening points for the guide’s front bracket in the centre of the garage door
(or slightly off-centre – Figure 11).
Depending on the type of material, the front bracket can be fastened
using rivets, anchors or screws (Figure 26). If positions A, B, and C (figure

8) allow it, the bracket can be fastened directly to the ceiling.

2 After drilling the holes, leave the head of the gearmotor on the ground,
lift the guide from the front and secure it with two screws, anchors or riv­ets depending on the type of surface.

3 Secure the mounting brackets [L], using the screws [M] and nuts [N],

Description

Radio receiver aerial connection input. The FL1 has a built-in aerial, alternatively an
external aerial can be used or the small piece of wire that is already connected to the
terminal can be left, which acts as an aerial.

Input for manoeuvre control devices; “Normally Open” type contacts can be connected.

Input for the devices which block or eventually stop the manoeuvre in progress. Con­tacts like “Normally Closed”, “Normally Open” or constant resistance devices can be
connected using special procedures on the input. Additional information on STOP can
be found in paragraph “5.3.2 STOP input”.

Input for safety devices such as PH0 photocells. Cut-in during closure, inverting the
manoeuvre.
“Normally Closed” contacts can be connected. The PHOTO input is factory set short­circuited by means of a jumper between inputs 3 and 7 of the terminal. Additional infor­mation on PHOTO can be found in paragraph “3.3.4 PH0 Photocells (optional)”.

All safety devices are controlled each time a manoeuvre is performed and the manoeu­vre is only performed if the test has a positive outcome. This is possible by means of a
special connection; the “TX” photocell transmitters are powered separately in respect to
the “RX” receivers. Additional information on connections can be found in paragraph
“5.3.1 Phototest output”.

An FL1 flashing light with a 12V 21W car bulb can be connected to this output. During
the manoeuvre the unit flashes at intervals of 0.5 s.

TABLE 6

3.4 – POWER SUPPLY CONNECTION

The connection of the GD0 control unit to the mains must be

made by a qualified electrician.

To carry out tests, insert the plug for GD0K in a power outlet; if necessary,
use an extension cord.

3.5 – INITIAL CHECKS

As soon as the control unit is energized, you should check the following:

1 Make sure that the LED [A] flashes regularly, with about one flash per
second.

2 If the system is equipped with the PH0 photocells, make sure that the
SAFE LED [B] shown in figure 59 flashes (on both TX and RX). The type of
flashing is irrelevant, it depends on other factors; what matters is that it is
not always off or always on.

3 If the system is equipped with the KS1 key-operated selector switch,
make sure that the night light [C] is on.

4 If the above conditions are not satisfied, you should immediately switch
off the power supply to the 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”.

3.6 – REGOLATIONS

3.6.1 – Selecting door speed

The door can be opened and closed at two speeds: “slow” or “fast”.

To switch from one speed to the other press the P2 button [B] momen-
tarily; 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”.

3.6.2 – Selecting the type of operating cycle

The opening and closing of the door can take place according to different
operating cycles:

• single cycle (semiautomatic): the door opens with a command and stays
open until the next command is given, causing it to close.

• complete cycle (automatic closing): the door 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 P3 [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”.

3.5.1 – Recognition of the door’s open and closed positions

The opening and closing positions of the door must be recognised by the
control unit. In this phase, the door stroke from the mechanical closing
stop to the mechanical opening stop is detected. In addition to the posi­tions, the STOP input configuration and the presence or non-presence of
the PHOTO input “Phototest” mode connection are also detected and
memorised in this phase.

1 Make sure that the carriage is attached.

2 Press key P3 [A] on the control unit and hold it down for at least three

seconds, then release the key (Figure 61).

• Wait until the control unit has completed the recognition stage: closing,
opening and re-closing of the door.

• If any device is triggered during the recognition stage, or the P3 key is
pressed, the recognition stage will be immediately interrupted. In this case
it must be repeated from the beginning.

• During the recognition stage the courtesy light will flash just like the
flashing light.

3 An error has occurred if the LEDs P2 and P3 [B] are flashing at the end
of the recognition stage. See paragraph 5.5 “Troubleshooting”.

4 Press button 1 of the “TX4” transmitter to perform a complete opening
manoeuvre. Then push it again to perform a complete closing manoeuvre.
The control unit memorises the necessary force throughout the travel dur­ing these two manoeuvres.

It is important that these two first manoeuvres are not interrupted by any
commands. If the manoeuvres are not completed, repeat the recognition
procedure starting from step 1.
The position recognition stage can be repeated at any time in the future
(for instance, if one of the mechanical stops is moved); just repeat starting
from step 1.

WARNING: if the belt is not tightened properly, during the search
for the positions it may slip on the pinion. If this happens, stop the
leaning procedure by pressing key P3 and stretch the belt by tight­ening the nut [D]. Then repeat the recognition procedure starting
from step 1.

3.5.2 – Testing the radio transmitter

To test the transmitter just press one of its 4 keys, make sure that the red
LED flashes and that the automation carries out the related command.
The command associated to each button depends on how it has been
memorized (see paragraph 5.4 “Memorization of Radio Transmitters”).
The transmitter supplied has already been memorized and when you
press the buttons the following commands are transmitted:

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.

STEP 4

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 GD0 automation system do not require any spe­cial maintenance. However, periodically make sure (at least once every six

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 standard
12445 which establishes the test methods for sectional and over­head door automation systems.

3.7.1 – Testing

1 Make sure that the provisions contained in chapter 1 “WARN­INGS” have been carefully observed.

2 Using the selector switch (if provided) or the radio transmitter, test the

opening and closing of the door and make sure that the door moves in the
intended direction.

The test should be carried out a number of times to make sure that the
door 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 (if provided) 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 standard 12445. 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.

6 Ensure that the entire mechanism is correctly adjusted and that the
automation system inverts the manoeuvre when the door collides with a
50 mm high object on the floor.

7 Ensure that the automation prevents or blocks the opening manoeuvre
when the door is loaded with a mass of 20 Kg, fixed in the middle of the
doors lower edge.

3.7.2 – Commissioning

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 56), analysis of hazards and solutions adopted, manufacturer’s decla­ration of conformity of all the devices installed. For GD0 use Annexe 1 “EC
Declaration of Conformity of the GD0 components”

2 Post a label on the door 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 Post a permanent label or sign detailing the operations for the release
and manual manoeuvre (use the figures in Annex 3 “Operating guide”).

7 Before commissioning the automation system inform the owner regard­ing dangers and hazards that are still existing.

8 Post a permanent label or sign with this image on the door (minimum
height 60 mm) with inscription WARNING – RISK OF CRUSHING.

an obstacle and reverses the movement.

STEP 5

The following chapters describe different ways of customizing GD0 to
make it suitable for specific application requirements.

5.1 – ADVANCED ADJUSTMENTS

5.1.1 – Adjusting the Parameters with the Radio Transmitter

The parameter adjustment operation can be performed using a radio
transmitter, provided it is memorized in mode 1 like the one supplied. If
no transmitter memorized in Mode 1 is available, you can memorize one
just for this phase and delete it immediately afterwards (see paragraph

5.4.1 “Mode 1 memorization” and 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 7 based on the

parameter to be modified.

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 fric-

tion on the door. Excessive force can compromise the operation of the
safety system or damage the door.

• 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 standard 12445.

• The weather conditions may affect the movement of the door, therefore
periodic re-adjustments may be necessary.

5.1.2 – Checking the Adjustments with the Radio Transmitter

With a radio transmitter memorized in Mode 1 you can check the values
set for each parameter at any time by following the sequence described
below:

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 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 7.

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 60s.

5.2 – OPTIONAL ACCESSORIES

In addition to the devices featured in GD0, other ones are available as
optional accessories designed to enhance the automation system and
improve its safety and performances.

Warning: if the STOP input is used to connect devices with safety
functions, only the devices with 8.2KΩ constant resistance output
guarantee the fail-safe category 3.

During the recognition stage of the opening and closing positions of the
door, the control unit recognizes the type of device connected to the
STOP input; subsequently it commands a STOP whenever a change
occurs in the recognized status.

5.4 – MEMORIZATION OF RADIO TRANSMITTERS

The control unit contains a radio receiver for TX4 transmitters; the one
included in the package is 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 transmitter
supplied with GD0 is 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 paragraphs before you
proceed with their execution.

5.4.1 – Memorization Mode 1

1 Press button P1 [B] for at least 3s.

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.

ing of the door even in the event of power failures.

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 GD0 automation system at
any time.

Do not add any devices until you have made sure that they are
perfectly compatible with GD0; for further information contact
MHOUSE Customer Service.

5.3.1 – Phototest output

This control unit is equipped with the “Phototest” function that increases
the reliability of the safety devices, making it possible to achieve “catego­ry 2” according to the EN 954-1 (edit. 12/1998) regarding the control unit
and safety photocells.

Whenever a manoeuvre is begun, the relative safety devices are checked
and only if everything is in order will the manoeuvre start. If the test has a
negative outcome (photocell blinded by the sun, short-circuited cable
etc.), the fault is recognised and the manoeuvre is not performed.

To add a pair of photocells, remove the jumper and connect as follows.

The photocell transmitter power is taken between terminals 8-6 of the
“Phototest” output and not from the services output. The maximum cur­rent that can be used on the “Phototest” output is 100mA.

Activate the synchronism as described in the Photocell instructions, in the
event there are two pairs of photocells that could interfere with one another.

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:

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.

5.4.4 – Deleting a Radio Transmitter

Only if the system features a radio transmitter, you can delete it from the
memory by proceeding as follows.

If the transmitter is memorized in Mode 1, only one deletion procedure will
be needed and at step 3 you can press any button. If the transmitter is
memorized in Mode 2, one deletion procedure will be needed for each key
memorized.

1 Press the P1 button [B] (figure 71) on the control unit and hold it down.
2 Wait until the P1 LED [A] lights up, then, within three seconds:
3 Press the key on the radio transmitter to be deleted and hold it down for

at least three seconds. If the deletion procedure is successful, the P1 LED
will flash rapidly five times. If the P1 LED flashes only once slowly, it means
that the deletion procedure has not been successful because the trans­mitter is not memorized.

4 If there are other transmitters to be deleted, press the P1 key and repeat
step 3 within ten seconds, otherwise the deletion procedure will be termi­nated automatically.

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, then wait

until it has flashed 3 times.

3 Release the P1 button precisely upon the third flash.
4 Wait approximately 4 s 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.

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.

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 Press button P1 (figure 71) on the control unit as many times as the num­ber corresponding to the desired command, according to the following table:

2 Make sure that the P1 LED makes as many quick flashes as the number
corresponding to the selected command.

3 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.

4 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.

5.4.3 – Remote memorization

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.

Probable cause and possible solution

• Check to see if the batteries are exhausted, if necessary replace them (paragraph 7.3.4 “Replacing the
Remote Control Battery”).

• Make sure that the power cord is properly plugged into the mains outlet

• Check to see if the fuses [D] or [E] are blown; if necessary, identify the reason for the failure and then

replace the fuses with others having the same current rating and characteristics.

• Make sure that the commands are actually received. If the command correctly arrives to the control unit,
the “OK” LED will make two long flashes.

• 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 11 (Paraghraph 5.6.1 “Photocells”).

• The selected force is too low to move the door. Check for possible obstacles and if necessary select a
higher force as described in chapter 5.1 “Advanced adjustments”.

• Make sure that there is voltage between the flashing light terminals 9 and 10 (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.

• Replace the lamp [F] with one having the same characteristics.

Control with safety devices out of order

If the safety devices are out of order or malfunctioning, it is still possible to
control the door.

1 Operate the gate control device (remote control or key-operated selec­tor switch). If the safety devices enable the operation, the door will open
normally, otherwise: actuate the control again within 3 seconds and keep
it actuated.

2 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 door will stop.

If the safety devices are out of order the automation must be repaired as
soon as possible.

Gearmotor release

The gearmotor is equipped with a mechanical system which allows the
door to be opened and closed manually (i.e. as if GD0 were not present).

The manual operation must be resorted to in case o power failures or sys­tem malfunctions.

1 Pull the release cord until you hear the carriage being released.

2 At this point you can move the door manually.

3 To restore the functionality of the automation system, move the door

back in position until you hear the carriage being engaged.

The activation of the manual release may cause an uncontrollable
movement of the door if the springs are weak or broken, or if the
door is off-balance.

7.1.3 – Maintenance Operations to Be Performed by the User

The operations that must be periodically performed by the user are listed
below.

• 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.

I

STEP 7

This guide should be stored in an accessible location and made available
to all users of the automation.

7.1.1 – Safety regulations

• Keep an eye on the moving door and keep at a safe distance until
the door has completely opened or closed; do not cross the opening
until the door has completely opened and stopped.

• Do not allow children to play near the door or with its controls.

• Keep the transmitter out of the reach of children.

• 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.

7.1.2 – Door Control

With radio transmitter

The radio transmitter is ready for use and the four buttons have the fol­lowing functions:

• Disconnect the power supply to the automation before you pro­ceed to remove leaves and debris, to prevent anyone from activating
the door.

• Periodically check the system, especially cables, springs and sup­ports, for possible imbalance or signs of ware or damage. Do not use
the automation system if repair or adjustment is necessary, in as
much that a fault or an incorrectly balanced door could cause injury.

7.1.4 – Replacing the Remote Control Battery

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 two 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.

7.1.5 – Lamp replacement

Before proceeding, disconnect GD0 from the power supply.

1 Unscrewing screw [A] and pushing button [B], open the lid.

2 Push the lamp up and rotate to remove. Insert a new 12V / 10W lamp

with BA15 socket.
