General Safety Instructions

• These Installation and Operating Instructions (MBA) must be read,
understood and observed by the person installing, operating or
maintaining the drive mechanism.

• The manufacturer accepts no liability for damage or malfunctions caused
by failure to follow theses Operating Instructions.

• Make sure that these Operating Instructions are readily accessible in the
garage.

• Observe and comply with the locally applicable accident prevention
regulations and EC standards.

Our new garage door drive mechanisms 'marathon 550 SL' 'marathon 800
SL' and 'marathon 1100 SL' combine reliability with innovation. The new
'marathon 550 SL' range replaces the current 'marathon S 550 N',
marathon S 800 N' and 'marathon S 1100 N' models whilst offering new
functions and connecting options (e.g. soft run, 2nd button, interface for
TorMinal, etc.).

As the connection set-up of the 'marathon 550 SL' control unit is not
compatible with the current 'marathon' models, the latter can only be
upgraded to 'marathon SL' models by replacing the control unit as a whole
or converting the control unit housing.

Furthermore, the new drive is supplied with our new radio control system
based on a frequency of 868.8 MHz, which offers enhanced security
standards. The system features rolling code technology, where the code is
changed for each new radio command, thus offering optimum security.

• Only install the drive mechanism to correctly aligned and weight­balanced doors. An incorrectly aligned door could cause serious injury or
damage to the drive mechanism.

• Doors that operate automatically by means of the drive mechanism must
comply with the following standards: EN 12604, EN 12605.

• Installation, connection and initial operation of the drive mechanism may
only be carried out by qualified specialists.

environment at an ambient temperature of between -20°C and +50°C.

• The drive mechanism should be stored horizontally.

Operation-related Safety Instructions

• The drive mechanism may only be operated if a risk-free force tolerance
has been set. The force tolerance must be set as low as is required to
ensure that the door's closing force does not constitute a danger
(see 'Force Setting' section).

• Keep your hands clear of any moving door or any moving parts.

• Keep children, disabled persons and animals away from the door.

• Only drive into and out of the garage when the door is fully opened.

• Closing edges and workings of the door pose risk of injury.

Safety Instructions for Radio-controlled
Operation

• The radio remote control may only be used for equipment and systems in
which defective remote operation of the transmitter or receiver does not
constitute a risk to people, animals or objects, or in cases where this risk
is eliminated by means of additional safety facilities.

•

Use of the radio remote control in conjunction with equipment or systems
subject to an enhanced risk of accident (e.g. crane systems) is prohibited!

• To ensure safe operation, local safety regulations relevant to the
equipment concerned must be observed! Information regarding this can
be obtained from electricity suppliers, the VDE and employers' liability
insurance associations.

• The user must be made aware of the fact that the remote control of
equipment with accident risk potential may only occur, if at all, when the
equipment concerned is clearly visible.

• Radio remote control may only be used if movement of the door can be
supervised and there are no persons or objects in the area of movement.

• Store the manual remote control such that there is no risk of it being
accidentally operated by, for instance, children or animals.

Installation Tips

• Check that all the parts have been supplied before you start installation
work in order to save time and unnecessary work if a part is missing.

• The drive mechanism can be installed to one side of the door if it cannot
be installed at the centre. It is important to note that the door does not
bend as a result and jam in the guide rails.

Check

Open and close the door several times by hand holding it at the point
where you intend fitting the drive mechanism. If the door can be moved
in this way without difficulty (in compliance with the above forces), then
the drive mechanism can be fitted at this point.

• Emergency Release
In the case of a garage without a separate entrance (e.g. slip door), the
emergency release of the drive mechanism must be operable from the
outside. To this end, you should fit a Bowden wire or a release lock,
accessible from the outside. See 'Accessories' section.

• Door lock
With doors supplied without the current door locking system, opening
approximately 50 mm by hand, this should be replaced by a spring latch.
This spring latch can be connected across the locking set to the drive, so
that when the door opens the spring latch locks first and then the drive
starts to open the door. Spring latches can be built onto the left, right or
middle of the door. Ask your dealer for details.

• Canopy doors
As the mechanical lock of a door with a drive mechanism has to be
dismantled or activated, it is possible to open the door manually up to
approx. 50mm depending on the door construction.

In order to accommodate this, spring latches that lock the door in
addition to the drive can be mounted. These spring latches are
connected to the drive via a locking set in order to first unlock the spring
latches before a drive opens the door when opening the door.

• Installation should be carried out quickly and safely by two persons

• All-round or side-sectional door
The polarity of wires 12 + 13 of drives that have to push one the
above-mentioned doors open has to be changed. See marathon SL
Control Unit fig. 29.1 terminal 12 + 13.

Safety Tips

• Installation, connection and initial operation of the drive mechanism may
only be carried out by qualified specialists.

• Do not operate the door when people, animals and/or objects are in its
area of movement.

• Keep children, disabled persons and animals away from the door.

• Door installation should be carried out by two persons, thus ensuring
safe and fast completion of the work involved.

• Safety goggles should be worn when drilling the mounting holes.

• Cover the drive mechanism up when drilling to ensure it does not get
soiled.

Before Installation

Very important to note!
The walls and ceiling must be firm and stable. Only fit the
drive mechanism to a correctly aligned door. A door that has
not been aligned correctly can cause serious injuries.

• Doors that operate automatically by means of the drive mechanism must
comply with the following standards: EN 12604, EN 12605.

• Doors must be stable because they are subjected to high tensile and
compressive forces. Light doors made of plastic or aluminium must be
strenghtened before installation if necessary. Ask your specialist retailer
for advice.

• Remove door locking system or disable same.

• Check that the door runs easily.

• The door must be balanced.

Test :

Manually open the door half-way. It must stay still in this position. If the
door moves downards or upwards, mechanically readjust it. Ask your
specialist retailer for advice.

• If the drive mechanism requires a rail extension to be installed, it is
essential that the second ceiling mounting be fitted for this purpose.

• Check the clearance between the door's highest up-position (THP, see
fig. 16) and the ceiling. The minimum clearance is 35 mm and the
maximum 100 mm, whereby the drive arm can only be at an angle of
max. 30°. If the clearance is less than is permissible, the drive
mechanism has to be moved back and an extended drive rail fitted.
Ask your local stockist for advice.

• If your garage door is fitted with a slip door but no slip-door safety facility,
you need to have one installed (see 'Accessories' instructions).

• If your door has no slip door and your garage has no separate entrance,
install a release lock or Bowden wire to facilitate drive mechanism
release from the outside (see 'Accessories' instructions).

Fitting and Connecting Push-button

Very important to note!
When operating the push-button, the user should not stand in
the door's area of movement and must have a clear view of
the door.

Never run the push-button cable along a power cable as this can cause the
control unit to malfunction. The push-button cable is supplied connected to
the control unit.

• Install push-button (1) in an appropriate, easily accessible location
inside the garage. Minimum height from floor - 1.6 m.

Do not install the push-button in the door's area of movement.

• Install connection cable (2) inside the garage.
Connect end of cable to push-button (1).

Useful Tip!
The Funkcody, a radio-operated interior switch and a key switch

General Information

SOMMER's new radio control system works at a frequency of 868.8 MHz,
so that code transfer occurs from the manual remote control to the radio
receiver. Each receiver can store up to 112 different codes. Each manual
remote control is allocated a factory-set radio code, whereby each
push-button or combination of buttons has its own code.

Example 1:

When setting various manual remote controls into a given receiver, only
push-button 1 should be programmed on channel 1, thus enabling 112
different manual remote controls to be learnt.

Example 2:

When setting various manual remote controls into a given receiver,
programming push-button 1 on channel 1 and push-button 2 on channel 2
means only 56 different manual remote controls can transfer their codes to
the receiver concerned.
If the user attempts to set more than 112 codes into a given receiver, all the
LEDs start to flash.

Safety Instructions

• To ensure safe operation, local safety regulations relevant to the
equipment concerned must be observed! Information regarding this can
be obtained from electricity suppliers, the VDE and employers' liability
insurance associations.

• The operator of this radio-controlled equipment is in no way protected
from interference from other telecommunications systems and facilities
(e.g. other radio-controlled equipment that is licensed to operate at the
same frequency range).

• Try replacing the batteries should reception problems be encountered.

Radio Receiver

- Setting button (1):
Selects various operating modes for the radio receiver: learning
mode, delete mode, normal mode.

If a user of a multi-user garage facility moves house and wants to take his
manual remote control with him, then all the codes of the given user's
manual remote control have to be deleted from the radio receiver.

Very important to note!
For security reasons, each manual remote control button and/or
combination of buttons should be deleted!

• Press setting button (1) and keep depressed for 5 seconds until an
LED starts to flash (any LED)

• Release setting button (1) - radio receiver is in delete mode.

• Press push-button on the manual remote control, the one whose
code is required to be deleted on the radio receiver - LED goes out ­deletion process complete.

- Repeat procedure for all push-buttons and combination of buttons.

Deleting a Channel from the Radio Receiver

• Press setting button (1) on the radio receiver and keep depressed

- press 1x for channel 1; LED(3. 1) lights up

- press 2x for channel 2; LED (3.2) lights up

- The LED that lights up depends on which channel has been
selected. LED flashes for 5 seconds. After a further 15 seconds LED
lights up again; the channel has now been deleted.

• Release setting button (1) - deletion process complete.

Deleting All Codes on the Radio Receiver

If a manual remote control is lost, then for security reasons all channels on
the receiver have to be deleted! After this has been done, all the manual
remote controls have to be re-set into the receiver.

• Press setting button (1) on the radio receiver and keep depressed.

- LED shines for 5 seconds. After a further 15 seconds the LED starts
to flash.

- After 25 seconds all the LEDs start to flash; all the channels have
now been deleted.

• Release teaching key (1); the LEDs go out, a sign that the deletion
process has been completed.

Connecting an External Aerial (marathon)

• An external aerial can be fitted if the possible range with the radio
receiver's internal aerial is insufficient.

• The aerial cable must not exert any mechanical load on the radio
receiver. Fit strain relief.

• Remove jumper (4).

• Connect external aerial (5).

Troubleshooting

All LEDS are flashing - the unit is attempting to occupy more than 112
memory slots on the radio receiver.

LED lights up - learning mode. Radio receiver is awaiting a radio code from
a manual remote control.

Initial Operation

Safety Instructions

Very important to note!
The force setting is relevant to the system's safety and must
therefore be carried out with due care and attention. An
excessively high force setting can injure people and/or animals
and damage property.

Select as low a force setting as possible to ensure that
obstacles are identified in a fast, safe manner.

• Keep your hands clear of a door in operation and any moving parts.

• Keep children, disabled persons and animals away from the door.

• Only drive into and out of the garage when the door is fully opened.

• Store the manual remote control such that there is no risk of it being
accidentally operated, by for instance, children or animals.

Setting Correct Length of Travel

The distance over which the drive mechanism moves the door can be
increased/reduced by using the cut-out buffer.

Check that the door opens and closes completely. If it does not, its travel
must be adjusted.

• Loosen cut-out buffer (4), move it and tighten it until the door closes.
Check the final travel position by opening and closing the door.
If necessary, repeat this process until the door closes completely.

• Loosen cut-out buffer (1), move it and tighten it until the door opens.
Check the final travel position by closing and opening the door.
If necessary, repeat this process until the door opens completely.

Programming Force Values

The control unit has an automatic force setting. When the door opens or
closes, the control unit automatically reads in the required force and
memorises it.

• Connect mains plug

When filament lamp (3) is not flashing, delete saved force values:

• Press push-buttons (3 + 4) and keep depressed until filament lamp
(3) goes out.

- Release push-buttons (1 + 2)

- Force values deleted.

Carry out procedure 2x:

• Close door

• Press push-button (1) 1x
Door opens as far as limit switch

• Lamp (3) and LED (29.11) start to flash

• Press push-button (1) 1x
Door closes as far as limit switch

• Filament lamp (3) and LED (29.11) flash

• Lamp goes out, force values have been memorised.

Important to note!
An additional force tolerance has to be set if, after the force
values have been set, the drive mechanism does not reach its
final travel positions.

Do not set any additional force tolerance if the drive mechanism
reaches its final travel positions correctly.

Checking Force Setting

When the force is correctly set, movement of the door in both directions
can be stopped by exerting slight hand pressure.

For each movement of the door, the control unit checks the force values it
has memorised against those required and automatically adjusts the values
accordingly.

The following measures can be taken if the force values set for opening
and closing the door are too high:

- reduce the force tolerance

- delete the force values by initiating a control reset and set the new
values

- check door

Setting Correct Force Tolerance

Check force adjustment on a regular basis, every year at least, to
ensure correct functioning. See 'Maintenance and Care' section.

If the force is insufficient to allow the full opening or closing of the door, the
tolerance can be increased by turning the adjustment on the potentiometer
in a clockwise direction.

The maximum force value allowed is automatically made up of the force
read in together with an additional force tolerance set via the potentiometer
(29.14). The potentiometer's furthest anticlockwise setting (-) is equivalent
to the least force tolerance, and its furthest clockwise setting the largest for­ce tolerance. If the setting is adjusted during opening or closing door, the
new setting is read in by the control unit when the door is next re-opened or
closed.

Once the force tolerance has been set, you may have to re-adjust the door
OPEN and CLOSED final travel positions if the required position is not
reached.

Procedure:

• Close door.

• Engage bogie unit:
pull once on the emergency release wire (N) if bogie unit
disengages.

• Remove control unit housing lid (1).

• Turn potentiometer adjustment (1) as far anticlockwise as possible
(4).

If filament lamp (3) does not flash - delete set force values:

• Press push-buttons (3 + 4) and keep depressed until filament lamp
(3) goes out.

- Release push-buttons (1 + 2).

- Force values deleted.

If filament lamp (3) flashes - read in force values:

• Press push-button (1) 1x
Door opens to limit switch without stopping

• Press push-button (1) 1x
Door closes to limit switch without stopping

• Press push-button (1) 1x
Door opens to limit switch without stopping

• Press push-button (1) 1x
Door closes to limit switch without stopping

• Force values for opening and closing have thus been taught.
Filament lamp lights up.

Test run:

• Press push-button (1) 1x
Door opens to limit switch without stopping

• Press push-button (1) 1x
Door closes to limit switch without stopping

• The force value has to be increased if the door does not reach its
final travel position providing the travel length has been set correctly.

•

Turn potentiometer (1) approx. 10 degrees in a clockwise direction (5).

Additional Functions

Early Warning Period (DIL switch 5)

When the push-button is pressed or the manual remote control is operated,
the warning light flashes for 3 seconds before the drive mechanism starts
up. If the push-button is pressed again or the manual remote control is
operated during the 3 seconds, the early warning period is ended
prematurely.

Back Jump (DIL switch 6)

This feature serves the purpose of supporting door and drive mechanism
operation. The drive mechanism moves briefly back in a door OPEN
direction once it has reached the door CLOSED final travel position, thus
taking some of the strain off the other equipment.

Partial Opening

(DIL switch 8)

This function opens the door either completely or partially, depending on
the given setting.

Ideas for use: garage ventilation, opening of side-opening door for personal
access, to name but a few. Partial opening functionality can be used by
using two push-buttons or the manual remote control.

Partial opening using 2 push buttons

Mount an additional push-button and connect as 'Push-button 2' to
terminals 4 + 5.

Push-button 1 always opens door fully. If the door has been partially
opened by pressing push-button 2, it can be fully opened by pressing push­button 1.

Push-button 2 only carries out partial opening when the door is CLOSED.
If the door is already fully OPEN or has been partially opened via push­button 2, it can be closed by again pressing push-button 2.

Procedure

1. Close door.

2. Set DIL switch 8 to ON, thus activating partial opening functionality

- always leave DIL switch 8 in ON position; the OFF position
automatically deletes the partial opening function that has been set.

3. Press push-button 2 (opens door from CLOSED final travel position)

- door opens until such time as push-button 2 is pressed again or OPEN

final travel position has been reached.

4. Press push-button 2 when the desired position has been reached.

5. Close door by pressing push-button 2.
The required partial opening adjustment has thus been set. Press

push-button 2 to open door to set position.
Set DIL switch 8 to OFF position to delete partial opening setting.

Partial opening via manual remote control

(2-channel operation)

Program button 1 on manual remote control to radio channel 1 and
push-button 2 to radio channel 2.

Radio channel 1 always has the same function as push-button 1.
Radio channel 2 always has the same function as push-button 2.

GB

26

For your own safety, select as low a force tolerance as possible
to ensure that obstacles are identified in a fast, safe manner.

• Repeat test runs until the door reaches the UP and DOWN final
travel positions.

Check door if drive mechanism is unable to open or close door
completely despite maximum force tolerance setting
(potentiometer 29.14 turned as far clockwise as possible).

• Fit control unit housing lid (1).

Code Transfer - Manual Remote Control to
Drive Mechanism

Important to note!
New radio frequency of 868.8 MHz; the control unit is set the
codes from the manual remote control.

The drive mechanism must remain switched on whilst the radio codes are
being learnt.

• Press setting button (1) on radio receiver

- press 1x for channel 1; LED (3.1) lights up

- press 2x for channel 2; LED (3.2) lights up

- If no radio code is transmitted within 10 seconds, the receiver
switches back to normal operating mode.

- Interrupting setting mode: press setting button (1) as often as
required to put out all LEDs

• Press required button on the manual remote control (5). The manual
remote control transfers the code to the radio receiver.

• The LED which goes out, depends on which channel has been
selected.

See 'Radio Receiver 868.8 MHz' section for details of deleting
radio codes

Defined Opening and Closing (DIL switch 7)

Push-button/radio channel 1 opens and push-button/radio channel 2 closes
the door. 2-channel operation can also be used either via the relevant
push-buttons or via the manual remote control.

Settings:

- DIL switch 7 ON

- DIL switch 8 OFF

- a 2nd push-button on the manual remote control has to be read on to
radio channel 2.

Relay Output (Terminals 23 + 24)

Each time the drive mechanism starts up, a pulse is sent to the relay outlet.
This could be used to switch on stairway lighting via an automatic light­switching system. Further settings only possible Via TorMinal.

Automatic Close Mode (Potentiometer 29.13)

Important to note!
Installation of a light barrier or safety contact strip is advisable.
An additional light barrier can be connected to act as an extra
safety facility.

In automatic CLOSE mode, the door is automatically closed after the OPEN
period set via potentiometer (29.13) has elapsed. Use of this mode means
the door can only be opened via a push-button or manual remote control,
but not closed. Nor can the door be stopped in its opening cycle by issuing
a command.

If a further command is given during the door's automatic closing cycle, the
door then opens completely. A command given during the door OPEN
period restarts the given set period.

The partially OPEN function is automatically deactivated when the
automatic CLOSE mode has been set.

The interior lighting can be used as a second warning light. This involves
the interior lighting being disconnected and an external warning light
connected in its place.

In automatic CLOSE mode, the interior lighting and any external warning
light that has been connected have one and the same function, i.e. to flash.

Example

- External warning light 1 connected to terminals 16 + 17, mounted to the
outside of the garage.

- Warning light 2 connected to terminals 18 + 19, mounted on inside of
garage.

Time can be set via potentiometer (29.13) for between 1 and 120
seconds.

Automatic CLOSE Mode - Option 1

The automatic CLOSE mode is automatically activated when the door
reaches the OPEN final travel position. The period set via the potentiometer
starts running from this moment onwards. A command given during the
door OPEN period restarts the given set period.

Settings:

- Potentiometer (29.13) set to required time (1 - 120 seconds)

- DIL switches 7 + 8 OFF

- Other DIL switches set as required

See 'DIL Switch 29.8' section for details of behaviour of drive mechanism.

Automatic CLOSE Mode - Option 2

As described above, apart from the fact that the drive mechanism closes
the door 5 seconds after the light barrier has been crossed. With this
alternative, a safety contact strip can only be connected with an evaluation
device.

Settings:

- Potentiometer (29.13) set to required time (1 - 120 seconds)

- DIL switches 1, 7 + 8 OFF

- DIL switch 4 ON

- Other DIL switches set as required

See 'DIL Switch 29.8' section for details of behaviour of drive mechanism.

Automatic cut-off of supply ­Obstacle Identification

If, when opening the door, an obstacle is encountered or the light barrier is
interrupted, the drive mechanism recognises this and reacts in accordance
with the given DIL switch 1 setting. See 29.8.

If, when closing the door, an obstacle is encountered or the light barrier is
interrupted, the drive mechanism recognises this and reacts in accordance
with the given DIL switch 3 setting. See 29.8.

Interim Stop

If an interim stop occurs due to the operation of a push-button or the
manual remote control, the drive unit stops immediately. The next command
given sends the drive in the opposite direction. See 'Impulse Sequence of
Door Movement' section.

Safety Stop (Emergency Stop)

If the safety input (somebody crosses the light barrier) or the automatic
cut-off of supply function is triggered, the drive mechanism stops, reverses
or opens the door, depending on the given DIL switch setting:

-DIL switch 1 + 3 - see 29.8.

The drive mechanism's next movement is always away from the obstacle
concerned:

- safety stop during door closing - door opens

- safety stop during door opening - door closes.

Overload Protection

If the drive mechanism is subjected to excessive strain when opening or
closing the door, this is recognised by the control unit which then stops the
drive mechanism. After approx. 20 seconds or a control unit reset, the
control unit deactivates the overload protection.

The drive mechanism can now recommence normal operation.

Operation after Power Failure

In the event of a power failure, the programmed force values are stored in
the memory. The drive mechanism's first movement after a power failure is
always in the door OPEN direction.

What Purpose Does the 2nd Push-button
Serve?

Defined Opening and Closing (2-channel Operation)

If this function is used, a second button can be connected to terminal 4 + 5.
For setting details see 'Additional Functions' section. This enables the door
to be opened using one push-button, and closed using another.

Operation and Handling

Safety Instructions

• The drive mechanism may only be operated if a risk-free force tolerance
has been set. The force set should be so small that the closing force
does not constitute an injury risk. (See 'Force Setting' section).

• Keep your hands clear of a door in operation and of any moving parts.

• Keep children, disabled persons and animals away from the door.

• Only drive into and out of the garage when the door is fully open.

• Closing edges and workings of the door pose risk of injury.

Opening Door

• Press push-button (1) or button on manual remote control 1x.

• The door stops if the button is pressed during its opening cycle. See
DIL switch 7 setting.

• The door closes if the button is pressed again.

Closing Door

• Press push-button(1) or button on manual remote control 1x.

• The door stops if the button is pressed during its closing cycle. See
DIL switch 7 setting.

• The door opens if the button is pressed again.

Pulse sequence of gate movement

Pulse sequence is set using DIL switch 7.
OFF : Open - Stop - Close - Stop - Open - etc.

ON : - Push-button 1: Open - Stop - Open - Stop - etc.

- Push-button 2: Close - Stop - Close - Stop - etc.

Emergency Release

• Pull once on emergency release wire (N): the drive mechanism
disengages and the door can be opened by hand.

• Pull once again on emergency release wire (N): the drive mechanism
re-engages and the door can only be power-driven (see fig.).

• Door is fitted with a slip door but no safety mechanism for the slip
door - retro-fit slip-door safety mechanism (see 'Accessories'
instructions).

• Door has no slip door and garage no second entrance - install
release lock or Bowden wire option outside release access
(see 'Accessories' instructions).

Control reset

• Press button (1+2) and keep depressed until filament lamp (2) goes
out.

• When filament lamp has gone out, this means the force

Accessories

The accessories listed can be used in conjunction with all SOMMER
garage door drive mechanisms.

Slip-door Safety Facility

If your garage door is fitted with a slip door, you need to have a slip-door
safety mechanism installed.

Bowden Wire

If your garage has no slip door or separate entrance, you need to install an
emergency release mechanism that can be operated from the outside. The
Bowden wire enables you to extend the emergency release facility from the
drive mechanism to the door. Use the long Bowden wire if your drive
mechanism has a tilting arm, an extended drive shaft or if the garage is
equipped with swing-door fittings.

Release Lock

An alternative to the Bowden wire.

Adjustable Drive Shaft

If the clearance between the door's highest up-position and the garage
ceiling is less than 35 mm, you should install the drive mechanism further
away from the door and replace the existing drive arm with an adjustable
one.

Tilting Arm

This is needed for doors with a vertical guide rail (up-and-over doors).
Beware, stroke travel may be up to 700 mm shorter. Fit (long) Bowden wire,
if outside-access emergency release is required.

Important to note!

Installation of a tilting arm reduces net headroom by up to 160 mm.

Swing Door Fitting

This type of fitting is required for swing doors. The drive mechanism can be
ordered with the swing-door option.
Please contact the Manufacturer if a customised swing-door solution is
needed.

Vertical Sectional Door Fitting

A vertical sectional door fitting should be installed with the following door
types:

- single-walled doors

- doors wider than approx. 3.5 m

- doors with a ceiling-mounted guide rail.

Locking Set

If the door is equipped with a shearing mechanism or if the door can be
opened more than 5 cm in a closed state, an additional locking facility with
a spring-loaded catch should be installed.

Status Indicator

This indicates whether the door is OPEN or CLOSED.

Rail Extension

This is used to extend the length of stroke travel.
Example: the net length of travel of up-and-over door drive mechanism is
reduced by approx. 700 mm through the use of a tilting arm.

Ceiling Mounting

An additional ceiling mounting should be fitted if the rail is extended by

1.6 m or more.

Bow arm convertor System

A bow arm convertor is required to enable one-piece doors with canopy
operating gear to be electrically operated. Typically, canopy doors have a
spring located on the frame above the door opening and protrude from the
front of the garage to create a “canopy” when in the open position.

Impulse Generators

Key switch

Opening and closing the door from outside. As the button can only be
activated with a key, the opening and closing of the door by unauthorised
personnel is eliminated. A connecting wire from the control housing to the
key switch must be laid.

Funkcody

Opening and closing the door from outside. As the command to open and
close the door can only be set with an access code, the opening and
closing of the door by unauthorised personnel is eliminated.
No connecting wire should be laid from the control housing to the key
switch.

Radio operated interior switch

Opening and closing the door from inside. When fitting in a normal double
thick flush-box each preferred key can be included.
No connecting wire should be laid from the control housing to the key
switch.
