1.4 PRESCIBED USE / APPLICATION
Only the correct installation and maintenance by an authorized/qualified company
or person in agreement with the user manual, logbook, check lists and mainte-
nance lists can ensure the safe operation of the system.

EN –Original user manual - 1.1 | 2022
7
A qualified person is, according to EN 12635, a person who has the required train-
ing, qualified knowledge and practical experience required to install, test and main-
tain a barrier system correctly and safely.
1.5 CONFORMITY
The installation complies with the following EU Directives/ regulations:
EU
2006/42/
EC
Machinerichtlijn
EU
2014/30
EU
EMC richtlijn (elektromagnetische compatibiliteit)
EU
305/2011
EC
Verordening bouwproducten (CPR)
UK
Supply of Machinery (Safety) Regulations 2008
UK
Electromagnetic Compatibility Regulations 2016
UK
Construction Products Regulations 2013
The design and production have been executed compliant with the applicable prod-
uct standard EN 13241 and EN 12453.
A Declaration of Performance (DoP) and Declaration of Conformity (DoC) are oblig-
atory for this product. The DoP and DoC are included in Appendix A.
The CE or UKCA mark is located on the cabinet of the barrier.
1.6 DELIVERY
The barrier, drive and control unit must be installed by a fitter or an engineer who
also connects and programs any accessories. The barrier control unit is adjusted to
the options/accessories agreed with the user. The relevant options are laid down
during hand-over.

1.7 ELECTRICAL CONNECTIONS
Electrical connections must be made compliant with the supplied wiring diagram.
The system must be correctly earthed (Protective grounding in accordance with
DIN VDE).
Because EMC-related suppression components can leak current to the earth cable,
it is advisable that you do not protect the control unit with a Residual Current De-
vice. When switching on the system, a high starting current can be generated due
to the charging of the intermediate circuit.
If after measurement during commissioning it appears that the leakage current ex-
ceeds the permitted 3.5 mA, an additional grounding, in accordance with EN
60335-1 and IEC 30364-5-54, must be provided. Measurement is made according
to EN 60335-2-103. Consult your installer for this.
Take into account good shielding, for example an automatic circuit breaker 16A B
characteristic.
Ensure that the feeder cables are not carrying power during commissioning.
1.8 DELIVERY OF BARRIER
After installation and commissioning, by a Heras technician or a technician trained
by Heras, the cover of the barrier must be closed and locked. This is done to pre-
vent unauthorised access.

documents.
Warning: Risk of limbs getting crushed.
2.2 GENERAL SAFETY INSTRUCTIONS
•The operator must read the entire user manual before the barrier is used for
the first time. The instructions stated in the user manual must be observed
and complied with. All other forms of use can cause unexpected hazards and
are forbidden.
•Applying a third-party drive unit, motor and/or safety devices may affect
safety and will invalidate the CE mark.
•The barrier must only be put into use if all safety facilities are in place and
connected, and work properly.
•All faults which might present a source of danger to the user or to third per-
sons must be eliminated immediately.
•All warnings and safety notices on the equipment must be in place and clear-
ly legible at all times.
•It is not permitted to mount items to the barrier arm and / or housing other
than as prescribed by Heras. Think of traffic and other signs and such. This
can negatively affect the safe operation of the barrier.
•All alterations or extensions to the barrier must be carried out by qualified
personnel using parts which the manufacturer has defined as suitable for
such alterations or extensions. Any failure to comply with these instructions
will be considered as non-compliant behavior and will invalidate the manu-
facturer's guarantee, as a result of which the risk entirely transfers to the
user.
•Improper usage or servicing or ignoring the operating instructions can be a
source of danger for persons, and/or result in material damage.
•If the meaning of any part of these installation and operating instructions is
not clear, then please contact your supplier before you use the equipment.

2.3 SAFETY PROVISIONS
•To protect people and goods from injury or damage, the barrier is fitted with
safety provisions including safety loops and/or a laser scanner.
These serve as emergency provisions that immediately stop (and reverse)
the movement of the barrier. It is forbidden to use these provisions to stop
the barrier normally.
•For a barrier with hold-to-run control, the above-mentioned safety provisions
are not necessary and will therefore not be standard provisions.
With this type of operation, the barrier stops immediately as soon as the
switch is released.
2.4 INTENDED USE
Giving safe access for goods and vehicles accompanied or driven by persons in in-
dustrial, commercial or residential premises.
2.5 SAFETY DURING USE
Children or people with a disability must not operate the barrier. Parents
must supervise their children to prevent them playing with the barrier.
➔PARENTS ARE RESPONSIBLE FOR THEIR CHILDREN 
•Keep a safe distance from the moving barrier. Warning icons to this effect
•have been installed in various locations
•Only pass through the barrier when it is completely open.
•The barrier must not be opened in windy conditions; wind force >12 Beau-
fort. The barrier arm can swing in a way that can result in damage to the
construction.
•When hold-to-run-control is employed, the barrier must only be operated if it
can be seen completely, directly and in real-time. Operation must be via a
permanently installed operating device, for instance a key switch or push
button. This operating device must be located in such a way that the opera-
tor’s position is safe. The barrier must stop immediately when the button or
key is released.
Other operating devices are not allowed.
•The barrier must be able to move freely without obstacles in the passage and
entire area where the barrier can move. Do not insert objects above or under
the barrier arm that could block the barrier arm.
•The barrier arm must always be free from snow, ice or dirt that might affect
its behaviour. In the event of frost, check this before commissioning the bar-

rier. If the barrier arm is blocked, the barrier will not move at all or will not
complete its movement. Irregularities can damage the drive and / or trans-
mission.
•Climbing the barrier is strictly forbidden as people climbing the barrier could
get hurt if the barrier is started unexpectedly.
•Do not place any obstacles in the opening.
•Always lock the drive unit cabinet during use.
2.6 SAFETY DURING INSTALLATION, MAINTENANCE AND DISASSEMBLY
•When work is carried out or while cleaning the barrier, the power supply to
the system must be switched off and it must be ensured that it cannot be
switched on unexpectedly.
•To move the barrier manually, first switch the automatic fuse in the cabinet
to “off” and make sure it cannot be switched on again (e.g. by locking the
cabinet).
•The barrier is driven by means of a lever construction. This is located in the
cabinet. Beware of moving parts when carrying out maintenance in and near
the barrier cabinet.
•The EN 12453 and EN 13241 standard must be taken into consideration dur-
ing installation and maintenance. To achieve a good safety level, the above
standard and the national regulations must be taken into account in non-EC
countries.
•If the barrier is damaged, always contact the supplier for an inspection.

4DESCRIPTION
4.1 94X SERIES
The Heras 94x series is a range of impact tested dual beam vehicle barriers used to
control vehicular access to any kind of high security controlled areas.
The dual beams integrated with the unique fibre system provide formidable me-
chanical characteristics and greater energy absorption on impact than a conven-
tional barrier system. The barrier is applicable for perimeter and interior site use
and can operate both indoors and outdoors. Various beam lengths are available
from up to 6 meters clear opening.
Figure 2: 94X barrier terms
4.2 LOOP DETECTION
A detection loop is an induction loop embedded in the road surface that, with the
assistance of electronics, can detect a vehicle. When the loop detects a vehicle, the
barrier will open and/or stay open. Detection loops do not detect people.
4.3 LASER SCANNER
A laser scanner is a motion and presence related detection device intended for de-
tecting objects in the detection zone. The laser scanner must read in a reference
point as part of the installation process. The barrier will no longer close without a
reference point. The laser scanner will ensure that the barrier does not close, or
stops during closing if an object is in the field.

EN –Original user manual - 1.1 | 2022
15
The laser scanner can also be set so that the barrier opens when a vehicle ap-
proaches.
4.4 ACCESSORIES
4.4.1 Traffic lights (Optional)
Red/green signal lights that indicate the open/closed position statuses. People are
only allowed to pass through the barrier opening when the green light is on.
4.4.2 Flash light / beacon (Optional*)
A flashing beacon to ensure extra attention before and while the barrier is open-
ing/closing.
* In some countries, a flash light is obligatory.
4.4.3 Temperature kits (Optional)
In climates with extreme temperatures, the addition of a heater and/or cooler kit
will be necessary to ensure the motor functions optimally. If temperatures regularly
fall below 0°C, a low temperature modification kit may be required. If temperatures
regularly exceed 40°C, a high temperature modification kit may be required.
Systems operating in such temperatures without the recommended temperature
kits may have operational issues.
4.5 OPERATING MODES
The control software is available to users in two possible operating modes:
•hold-to-run mode
•automatic mode

EN –Original user manual - 1.1 | 2022
16
4.5.1 Hold-to-run mode
The barrier drive can be operated in hold-to-run operating mode with limited com-
fort. In hold-to-run operating mode, the barrier does not require safety features.
The barrier will move as long as an OPEN or CLOSE key is pressed.
It shall only be possible to operate the manual actuators in such a position
that allows full, direct and permanent real-time view of the barrier during the
barrier movement and ensures that the person controlling the barrier is not in a
hazardous position. No controls other than manual actuators are to be installed.
The barrier shall stop when the manual actuators is released.
4.5.2 Automatic mode
If the safety facilities have been installed completely, the motor drive will usually
work in this automatic mode. The user can only use all barrier functions in auto-
matic mode. Total safety of the barrier is guaranteed here by the activated safety
facilities.
Opening or closing the barrier can be initiated in automatic mode by means of:
•hold-to-run buttons OPEN and CLOSE
•impulse buttons OPEN, STOP and CLOSE
Every movement command causes the full action that has been selected to be per-
formed (open barrier, close barrier etc.). Every action is stopped immediately by a
stop command or a signal from the safety facilities.

6.2 AUTO-CLOSE TIMER
When the barrier system is set to ‘automatic logic’ and an open signal is received
from either a push button or card reader the barrier will open, should no vehicle
drive through the barrier then the barrier arm will re-close after a set time.
Adjusting this timer is done by turning the bottom potentiometer. See Figure 4:
6.3 ELECTRICAL LIMITS
The travel of the barrier is governed by 4 proximity switches and can be adjusted
by loosening the lock nuts.
The proximity switches have a maximum read range of 4 mm and a mini-
mum read range of 2 mm. Stay within this range and make sure the lock
nuts are correct and tight
The open angle must not exceed 85˚ as illustrated on the drawing. The
slowdown activation position, is 15˚ short of full travel as shown on the
drawing. 15˚ measurement is for both up and down positions.
