3. General safety instructions

WARNING!

Failure to comply with the documentation could

result in life-threatening danger!



Be sure to follow all the safety instructions in this docu-

ment.

Warranty

The function and safety of the equipment is only guaranteed

if the warning and safety instructions included in these

assembly instructions are adhered to.

The manufacturer is not liable for personal injury or damage

to property if these occur as a result of the warnings and

safety advice being disregarded.

The manufacturer does not accept any liability or warranty

for damage due to the use of non-approved spare parts and

accessories.

Intended use

The drives in the FTU series are suitable exclusively for

opening and closing re-resistant roller doors without spring

or weight compensation. The force transfer to the door takes

place via a chain drive.

In the case of doors that must be secured against falling, a

separate safety catch device is required.

Target group

Only qualied and trained specialist tters are permitted to

install the drive and perform mechanical maintenance.

Qualied and trained specialist tters must satisfy the

following requirements:

− Knowledge of the general and specic safety and accident

prevention regulations,

−Knowledge of the relevant regulations,

−Training in the use and care of appropriate safety

equipment,

−Capable of recognising the dangers associated with

assembly.

Only qualied and trained electricians are permitted to

connect the drive and perform the electrical maintenance.

Qualied and trained electricians must satisfy the following

requirements:

− Knowledge of the general and specic safety and accident

prevention regulations,

−Knowledge of the relevant electrical regulations,

−Training in the use and care of appropriate safety

equipment,

−Capable of recognising the dangers associated with

electricity.

Instructions regarding installation, connection and

testing

−The system must be disconnected from the electricity supply

before carrying out any electrical work. It must be ensured

that the electricity supply remains disconnected for the

duration of the work.

−It is essential to observe the local protective regulations.

−Observe the valid standards and regulations.

Information concerning operation

−If oil or emulsion mist is to be expected in the direct vicinity

of the drive, which can inuence the friction coefcient of

the brake, protection class IP65 must be selected.

−Unauthorised persons (particularly children) should not be

allowed to play with permanently installed adjusting or

control devices.

−Keep remote controls beyond the reach of children.

4. Product overview

4.1 4.1 Product descriptionProduct description

The drives in the FTU series are specially designed for re-

resistant doors without spring or weight compensation. They

form a model series from 250–1050Nm. They are connected

with the door shaft by a roller chain. In case of re, they close

independently and automatically by means of gravity alone,

without an energy supply.

In normal operation, the door is opened and closed again

through power operation by a three-phase motor. The gearing

consists of a non-self-locking spur gear unit, a centrifugal and

magnetic brake, an electric motor and an end position system.

The drives are not equipped with manual emergency

operation.

The door load is held by a magnetic brake that is released

immediately in case of re. The centrifugal brake ensures that

the door speed is limited.

In the case of doors that must be secured against falling, a

separate fall protection device is required.

4.2 4.2 VersionsVersions

The following versions of the FTU drive are available for

delivery:

4.4 4.4 Tensioning bracketsTensioning brackets

A special base means mounting the FTU drives is extremely

safe. These tensioning brackets, type MK-FT, enable tensioning

or re-tensioning of the chain drive at any time.

The list of available brackets and assignment to the individual

drive types can be found in the technical data.

5.1 5.1 Safety instructions for mechanical Safety instructions for mechanical

installationinstallation

WARNING!

Serious injuries possible due to incorrect installati-

on of the drive!

−All components for fastening, connection and the trans-

fer of force must be designed for the maximum loads

that can occur.

−The installation base (wall, pillar, etc.) must be suitable

for the maximum loads that can arise.

− Installation must take place whilst standing on a stable

foundation

(e. g. scaffolding).

ATTENTION!

Property damage due to improper installation of

the drive!

To avoid damage to the drive and door, only install the

drive if

−a special bracket for fastening the drive permits

tensioning or re-tensioning of the chain drive at any time,

−the drive is undamaged and not blocked,

−it has been checked after an extended time in storage

that the drive runs smoothly and does not exhibit any

corrosion,

− the ambient temperature is -20 ºC to +60ºC,

−the installation altitude does not exceed 1,000 m above

sea level,

−the correct protection type has been selected,

−no other danger sources are present,

−the installation location is widely cordoned off.

REFERENCE

When installing the drive on the door system, observe the

corresponding installation and operating manual from the

door manufacturer.

5.4 5.4 Installing the fall protection deviceInstalling the fall protection device

A roller chain is used for the transfer of force. Safe operation

of the roller/door system is therefore only possible in

connection with a fall protection device (e.g. external safety

catch device).

Fall protection must be additionally equipped with an electri-

cal disconnect device in the following case:

−The door drive is able to move the door leaf by motor

power after it has been stopped by the fall protection.

WARNING!

Life-threatening danger due to electric shock!



Before performing wiring work, always disconnect the

drive system from the power supply. Make sure that the

power supply remains disconnected during wiring work.

ATTENTION!

Property damage due to improper installation of

the drive!

In order to avoid damage to the drive, observe the

following points:

−Mains cables and control cables must be routed

separately.

−The line types and cross-sections must be selected in

accordance with the valid specications.

−It is essential to observe the local protective regulations.

− Observe the specications of the door manufacturer for

assembly.

−The mains voltage must correspond with the information

on the type plate for the drive and the wiring on the

motor terminal board.

−In the case of three-phase power, this must have a

clockwise rotating eld.

− With a xed connection, an all-pole main switch must be

used.

−With three-phase power, only triple block circuit breakers

(10A) shall be used.

−Observe the valid standards and regulations!

REFERENCE

In case of operation with a door control (e.g. CS320,

CS320FTU) consider the corresponding assembly manuals.

The CS320 FTU is installed in the combination housing and is

equipped with

−one additional power unit,

−two external relays for brake actuation and

−one separate connection terminal for accommodating

−the FTU motor cable,

−the UPS connection cable and the

Equipped with an additional power supply (UPS) for the

magnetic brake, the CS320 FTU operates in normal mode as a

door control with active safety devices.

In the event of a power failure, the magnetic brake continues

to be supplied via the UPS system and the door remains open.

In case of re, automatic (emergency) closing is implemented

by the re alarm system, independent of the mains power

supply.

The control and UPS are connected with each other in

accordance with the plug & play principle.

WARNING!

Life-threatening danger due to electric shock!



Before performing wiring work, always disconnect the

drive system from the power supply. Make sure that the

power supply remains disconnected during wiring work.

The drives of the FTU series are maintenance-free.

However, the drive must be checked by a qualied and trained

specialist at least once a year.

With a greater number of cycles the check must take place

more frequently.

The brake is subject to wear and must be checked regularly

and tested for functionality.

The hollow shaft must be kept free of rust.
