Notes
1 Important information
1.1 Use as prescribed
Our herein described barrier models and accessories are suitable for locking and opening
entries and exits to parking lots, access roads and entries for motor vehicles and motorbikes.
A different use or a use beyond the here described ones is not in line with the prescribed use;
especially not permissible for pedestrian traffic.
The control is only designed for operation with these barriers. Conversions or changes which are
not described herein are not permitted and need to be approved of in writing in each individual
incidence.
In case of improper use neither the manufacturer nor the distributor may be held liable for any
resulting direct injuries and/or damages or consequential damages.
1.1.1 Designated setting
The barrier may be mounted outdoors or indoors. All parts of the barrier are sufficiently protected
against corrosion in order to guarantee a long life span. The barrier base must be protected
against moisture with the aid of a pedestal. An escape (outlet) for rain must also be provided for.
The permitted temperature ranges are to be considered.
Mounting is not permissible in explosion-prone spaces or in spaces where hazardous and
combustible gases are present.
1.2 Influence of wind
The standard barrier pole fastening can withstand a maximum wind velocity of 10 (heavy storm)
or 28,5m/s resp. 102 km/h. With barrier pole length of more than 4m it must be taken into
consideration what damage can be caused in the case of barrier fracture of a vertically positioned
barrier pole.

1.3 Safety
1.3.1 General safety advice
This barrier is constructed and tested in order to guarantee sufficient safety when installed and
when used according to the following safety regulations.
The products have left our house free of faults. Still there can be risks involved when mounting or
during later operation, if the product has been installed or used improperly. Keep manual within
reach, so it can be consulted by the owner of the unit at any time.
The manufacturer cannot foresee each critical point which can be caused by the installed product.
The operator of the unit and the installer have to ensure that no risks may result for people or
objects. If parts of the unit are damaged (e.g. barrier pole broken) the unit must be taken out of
service. Only authorized and skilled professionals may make the necessary repairs. A complete
security check including proper documentation is necessary after the repair work.
1.3.2 Minimizing the risks
The installer of the unit has to take care to minimize possible remaining risks according to the
latest state of engineering.
Example 1: Put up sufficient signal panels, warning signs or surrounding construction in order that
pedestrians are adequately warned and do not cross the barrier unit’s path.
Example 2: Construct entry width for vehicles in a way so wider, longer and higher vehicles may fit
through entry without problems, i.e. without damaging the unit. Install clearly visible warning signs.
1.3.3 Safety for pedestrians
The utmost care must be taken to ensure the safety of pedestrians.
This means that this instruction manual must be followed carefully.
Also, country-specific directives and regulations in order to
avoid accidents must be considered and adhered to. A barrier unit is
not safe for pedestrians and/or cyclists and must not be operated by
either resp. be operateable by either. The installer or operator must
ensure suitable measures and separate pedestrian and vehicle traffic.
It is necessary to put up a sufficient number of warning signs and to
ensure security by means of construction (walls/fences etc.).
The pedestrian path must be outside the barrier path. The opening and
closing movements of the barrier must be carefully watched and sur
veyed. If no surveillance or monitoring is possible then operation is not
permitted.
1.3.4 Explanation of warning signs used in the manual
Possible risks and notes are indicated in the following way in this manual and operation guide:
WARNUNG / ACHTUNG:
This safety alert symbols mean "Caution " - failure to comply with such an instruction involves risk of
personal injury or damage to property. Please read these warnings carefully. Incorrect installation
and/or failure to comply with the following instructions may result in serious personal injury or property
damage.

Notes
1.3.5 Installation and maintenance
• All units must be connected according to our instructions.
• Before opening the control unit the power supply must be disconnected.
• In case of maintenance/repair work all command devices (radio, switches, push buttons, loops)
must be deactivated, so that the barrier does not move uncontrollably.
• There is a risk of jamming and getting caught due to moving parts when the barrier casing is
open (door/lid). Utmost caution should be taken with electrical power, tension springs and moving
parts.
• Minimum distance: 500mm between barrier pole tip and a solid obstacle.
• After installation is complete check to make sure that the mechanism is properly set and that the
drive, security system and emergency release function correctly.
• Remove all additional accessories out of the reach of children. Do not allow children to operate
push buttons or remote controls. Serious injury may be the result of a closing barrier.
• Upon start-up all necessary safety devices must be installed, working and tested. The locally
effective regulations must be adhered to.
• In case of maintenance, cleaning or service the roadway must be blocked from traffic.
• All command devices must be installed with direct visual contact to the barrier.
• During the movement of the barrier no people or vehicles may be directly under the barrier.
• When planning, mounting and operating the barrier care must be given towards cables and other
objects in the swivel axis of the barrier pole.
• The area for and around the mounting spot of the barrier must have a solid floor space with
heavy load capacity and must be free of obstacles.
• Start-up without proper anchorage of barrier unit to floor space is not permitted.
• The mounting/disassembly of the barrier pole is only permitted in calm wind.
• The mounting/disassembly of the barrier requires two people.
• With barrier pole length exceeding 4.5m we recommend a support or tip support post. If barrier
pole is 6m or longer this is a regulation and must be adhered to.
• The surface temperature of the motor can exceed 90°C. Potential danger of burning.
• In case of shut-down or in times when the unit is not checked, the barrier pole must remain
closed. If the barrier is to remain open, the barrier pole must be removed completely.

Notes
1.4 Service
Barrier units are not maintenance free and therefore need regular inspection. Hereby the number
and extent of the inspections depend on the frequency of use (number of cycles) and where the
unit is placed and less on the time span since the previous inspection. The operator must keep
an inspection record of all risks which describes and confirms the extent of the inspection.
An inspection record should contain:
• Visual inspection: apparent deficiencies, damages through vehicles, environmental influences
or vandalism. Visual inspection of safety installations and signposting. Frequency: depends on
where unit is placed and vehicle frequency: daily ? monthly to be carried out by a qualified /
experienced person (janitor, technician)
• Inspection / service: in addition to visual inspection. Complete inspection of unit regarding
mechanical signs of wear. If necessary exchange parts and repair.
• In order to make use of the guarantee it is necessary to conclude a maintenance contract with
the operator of the unit and to have regular maintenance / inspections of unit carried out.

5 Operation description
5.1 Operation of barrier
Barriers are available in models Right / Left. The casing is made of welded sheet steel (apart from
specific models) and is powder coated against corrosion. The drive unit and control are integrated
into the casing and accessible by lifting off the hood and opening the service door.
The drive motor is powered by the control and is fed by line voltage. Force and rotary motion are
transferred by a leverage system.
This leverage mechanism is defined ex works by a slow deceleration in both directions in case of
quick movement of barrier.
The effective force is limited through the applied capacitor and is defined ex works.
An incorporated sensor reverses the barrier in the direction OPEN if an obstacle should be hit.
The maximum run time of the motor as well as the opening time of the barrier are determined by
the drive in use and the time setting on the control (1-3-6 seconds).

Notes
5.3 Operation of barrier (straight pole)
Barriers with straight barrier posts are available in different
lengths. The straight pole moves from horizontal to the complete
vertical position. Short barrier posts can be opened very quickly (1
second), long posts must be openend more slowly (3 / 6 seconds)
in order to ensure lasting and safe operation of unit.
5.4 Operation of barrier (90° articulated pole)
The 90° articulated pole is used when there is only limited height
available or an ensuing height restriction is indicated at the barrier
(limited to car entry only). These types of barriers open in 3 – 6
seconds. For dimensions see Technical Data.
5.5 Operation of barrier (180° folding pole)
The 180° folding pole operates similarly to the 90° version. The
difference is that the pole is swung completely out of the way. This
leads to a height saving which can be used otherwise. This type of
barrier requires at least 3 seconds to open. For dimensions see
Technical Data.
5.6 Operation of barrier (lattice/fence)
(in preparation) The lattice barrier is used in combination with the straight barrier pole. The lattice
moves with the barrier pole and visually keeps pedestrians from passing through the barrier resp.
redirects to a pedestrian path. These barriers work slower due to additional weight – normally 6
seconds.
5.7 Operation of motor
The rotary motion of the motor is transferred to the axle via a buffer lever. The characteristic
mechanism lets the barrier open slowly at first, then it accelerates it and finally slows it down again
before reaching the end position. This prevents the barrier pole from slamming and helps increase
the life span. The special mechanics results in the barrier being totally irreversible and for the
mechanics to break down first. This renders the barrier extremely durable and in case of
vandalism or the barrier pole being damaged – only the barrier pole has to be replaced.
5.8 Operation of spring (balancing spring)
There are 2 resp 3 springs (depending on model) under the casing’s hood. The main spring and 2
buffer springs. The main spring is responsible for the balancing of the barrier pole and the pre-
stressing is adjusted according to barrier pole length. The buffer spring or emergency spring
guarantees a smooth travel and serves for added safety in case the main spring should break.
5.9 Operation of limit switches
End stops are attached to the intermediate lever as well as the limit levers, which have been
preset ex works to the 90° movement. A contact-free limit switch shuts the control off. After the
preset time the control shuts off the motor. An exact setting can ensure the shortest possible motor
run time, preventing the motor from heating up unnecessarily when travelling towards the end
stops and shutting down in this position after some time.

Notes
6 Installation
6.1 Foundation construction: barrier
A stable position of the barrier casing is imperative. We recommend a foundation with the following
minimum requirements. If there is a risk of frost, the foundation must be constructed in a way as to
ensure protection against frost – so the ground does not rise. All necessary ductwork and wires
have to be led out of the center of the barrier’s pedestal.
• Duct for power supply
• Duct for Photocell
• Duct for control wires
• Duct for loop connection 1
• Duct for loop connection 2
• Etc.
Barriers up to 6m
Depth: 900mm
Diameter: 500 x 500mm
Barriers up to 8m
Depth: 1 400mm
Diameter: 500 x 500mm
The upper pedestal area is to be constructed in a smooth, flat and absolutely horizontal way with
regard to the road, so the barrier casing can be mounted vertically. The used concrete should
comply with hardness BH PC 250 (25N/mm2). The pedestal must be constructed with solid steel
reinforcement. The drilled holes are to be designated according to the dimensions and to be
fastened to the composite anchors (Ø 20mm x 110mm).
6.2 Foundation construction: tip support post (support)
In order to mount the support, a stable and inalterable location is required. The support is fastened
by means of composite anchors (not included in delivery).

Notes
6.3 Contact loops (induction loops) – description
A contact loop reacts to metal and is especially suitable for safe operation of barriers.
The dimensions, number and installation of loops has to be executed with great care.
Principally the following applies:
• Control loops prevent a premature closing. The most important loop for this is located underneath
the barrier pole (see Examples) and has to secure the entire length of the barrier pole. As long as
the vehicle is standing on the loop the barrier cannot be closed. After leaving the loop the
automatic closing mechanism is activated. This may happen immediately or after a short delay.
• Opening loops are installed infront of barrier unit and activate it like a switch. The distance
between both loops may be 1m at the most. Larger distances may cause problems with short or
slow vehicles.
• Motorbikes and bicycles can also be recognized by the loops. For this purpose special lanes must
be created and identified (e.g. Motorbike Lane). A car loop cannot be a motorbike loop and vice
versa.
• The loops should be installed at a minimum depth underneath road surface. The deeper the loop is
situated the less the detection. Particularly vehicles with higher ground clearance and also trailers
might therefore not be detected. The detection of trailers or campers is difficult due to their flooring
often being made of wood and thus not being detectable until axle crosses the loop. Either a
second loop has to be installed behind the barrier which the pulling vehicle must cross first or the
automatic closing has to be adjusted according to the trespassing speed. Photocells may be
installed as an alternative for added security.

Notes
6.4 Installation of induction loops – general
The geometry has to be executed depending on unit:
• The loop has to be positioned exactly underneath barrier pole. The barrier pole is positioned on the
side of the barrier casing.
• The monitored area for cars has to be at least 500mm on both sides. For trucks the loops have to
be larger or a second safety loop must be installed.
• Keep loop at a distance of 300 – 400mm from road side.
• Faulty road surface, cracked areas, moving subsoil, loose paving, coarse gravel, metal parts may
be diagnosed as errors and thus disturb the operation. The subsoil must be stable and rigid.
• Avoid iron reinforcements in the road. This may lead to the loop being disturbed. Keep >50cm
distance from iron.
• Heated roads also disturb loop (keep > 100cm distance)
• Garage doors, rolling gates, sliding gates and wing gates disturb the loop’s operation if made of
steel. Keep a distance!
• The distance between the loop’s control and the loop itself may be max. 15 – 20m. If that is not
possible the diagnosis unit must be installed outside the barrier unit.
• The cable of the loop must be fitted exactly. Coiled cable interferes with analysis.
• The loop’s resistance must be checked after installation. It shoul be about 0.8 – 2.0Ohm. The insu
lation resistance against ground must be larger than 1MOhm. The inductance of the loop must be
between 70 - 500μHenry.

17/40
Notes
6.5 Installation of induction loops – procedure
Installation under asphalt or concrete:
• Size and positioning of loop(s)has been decided upon. Mark positions on the ground and check
again.
• The corners of the loops are to be executed at an angle of 45°. See Illustrations.
• By means of a cutting disk or similarly suitable tool a furrow must be cut into the road with a
depth of 50mm. the width of the furrow must allow for the cable which will be inserted at a later
point in time. The loop must lie evenly deep (parallel) with regard to road.
• The furrow must be very clean! A vacuum cleaner is ideal to remove dirt and small obstructions.
• The loop is laid with one insulated wire with a profile of 0.75mm² to max. 1.0mm² in diameter.
3 – 5 windings are laid. Now resistance and inductance can be measured.
If supply has already been installed then do a check!
• Secure loop with a plastic or wooden spatula.
ATTENTION: Do not damage cable insulation!
• Both wires are intertwined with one another in the supply line to the loop (between loop
evaluation and actual starting point of loop) in order to prevent another loop from occurring
• The supply line is led to the evaluation or is wired through the ductwork into the barrier casing
• The loop cable is now covered with fine quartz sand in order to fill the gaps between cable and
wall. At least 25mm have to remain free to road surface
• The furrow containing the loop can now be closed up. Take care when using hot potting
compound, such as bitumen! Temperatures of 90°C damage the cable isolation and destroy the
loop. Laying under interlocking stone pavement. Pay additional attention!
• There has to be enough room between the individual stones of the pavement and the loop
(30mm). The stones may move in the course of time and damage the loop.
• The loop is laid as described above with 3-5 windings – not directly into the sand but through a
customary plastic duct with a small diameter. The diameter must be small in order to prevent the
cable in the loop from moving in case of vibrations (car). The windings can also be held together
by means of cable ties. The plastic duct prevents dirt from entering due to the weight of the cars.
These measures should be prepared in the workshop and not as late as on site. The loop can
also be tested in the workshop by placing it partly under a parked car.
• The duct in which the loop is laid is to be marked and excavated. Position loop inside and cover
with fine quartz sand. Do not use grit or gravel, as these materials do not remain firm and stones
may damage the loop.

Notes
6.6 Installation of operation switches
Operation/command devices must be placed such as to ensure easy access from inside the
vehicle. They must be in direct visual contact with regard to barrier. Poorly placed switches and
pillars represent possible safety hazards.
6.7 Usage of Photocells
Photocells are especially suitable as an alternative to a contact loop; though even more effective
in combination with a safety loop. Especially when trailers, campers or trucks with trailers pass
through the barrier, Photocells are perfect. Ideally Photocells are positioned directly under the
barrier in order to recognize an object and delay the closing motion. They may also be installed
behind a barrier so as to send a further signal and thus prevent the barrier from closing or delay
the closing motion some more. The height of the installation depends on the situation and should
be located at a position which does not let the invisible light beam transmit underneath the
vehicles (truck, SUV).
Reflector Photocells are not suitable for operation, as vehicle finishes, sun or strong rain lead to
incorrect reflector operation.

7 Mounting
7.1 Service door
The included key (2 keys) is necessary to open the service door. It can
be found in the accessory package which is included in the barrier’s
transport packaging. On the inside of the service door the already pre-
installed and partly wired control is situated.
Attention: Inside the barrier electrical parts are located which are live
wired!
WARNING: The mechanics inside of the barrier can lead to serious
injury if barrier is activated.
7.2 Removing the hood
Attention: Disconnect barrier from power supply. Inspection necessary!
The hood is secured by means of a wing nut which is only accessible
when service door is open. In order to remove hood, reach into barrier
with hand and remove wing nut (twist off). Now lift up hood on door
side, approx. 2cm.Then, in lifted position, move backwards in the
direction of barrier pole and lift hood off completely.
Note: Hood is secured with one wing nut. A second one may be used if
necessary. This is not required for technical reasons. It is impossible to
remove a hood that is secured with a screw without this leading to
strong and lasting damage.
To place hood back in original position go through above steps in
reverse order.
Transport: For transport a plastic film is placed between hood and
casing in order to prevent the finish from getting damaged.
This precaution may be removed upon installation.
7.3 Release (manual operation)
For this purpose the release key is necessary which can be found in
the accessory package of the barrier.
On the side where the service door is located there is a drilling in the
hood. The release key must be inserted here and in order to release
barrier the key must be turned clockwise.
Barrier may only be locked again as in the initial position when
released. If barrier was closed never leave barrier pole unsecured in
open position, as it may move downwards unchecked. The manual
release is reserved for emergency situations or in case of maintenance
work and is not suitable for daily use.
The release function can be deactivated and is thus not accessible from
the outside if misuse is to be expected. For this purpose find enclosed
in the accessory package a small fastening which can be inserted into
the release drilling before the hood is put on.

Notes
7.4 Mounting the barrier (casing)
Note: 2 people required! The necessary parts can be found in the accessory package included in
the delivery contents of the barrier.
2x U-profiles
4x composite anchors Ø20mm x 110mm long
• Indicate drillings for composite anchors and prebore
• Position barrier and tighten screws slightly
• With barriers up to a length of 4m the final alignment can be executed after mounting the barrier
pole
• With barriers longer than 4m the alignment must be executed immediately (without barrier
pole) and the screws are tightened firmly
ATTENTION: It is important that the composite anchors are fitted well in order to prevent barrier
from becoming dislodged. Especially in case of long barrier poles this can be dangerous!
• The gap between the base of the barrier casing and the pedestal has to be grouted with silicone
to prevent moisture from entering (important for protection against corrosion).
7.5 Mounting the tip support post (support)
Mounting the pole strut should be done after barrier pole has been fitted and aligned.
Installation is executed by means of composite anchors (not included in delivery) in the
ground and on a solid and stable subsoil.
A pendulum support is available as accessory.
7.6 Mounting the barrier pole (straight)
Attention: 2 people required to secure barrier pole.
Barrier must be in “Closed” position. Barrier pole is slid onto attachment and fixed in place by
means of the cover plate and the two provided screws (accessory package barrier). The nut must
be put on from the outside resp. the screw is to be slid through from the inside out. The barrier
pole has to have a firm fit on the arm and must not move nor have any clearance. The screws
allow tightening. If the screws appear to be too short to begin with, omit the washer and/or the
circlip. After tightening both screws slightly, loosen one screw and remove it in order to provide
washer and circlip. Tighten screw again and now retrofit other screw.
