function of the gate opener / barrier.
In order to reduce the risk potential related to the movement of the barrier boom, additional optical
and/or acoustical warning devices should be installed.
2.2 Notes on safety for the operation
Children from the age of 8 years and persons with reduced physical sensory or mental capabilities or
lack of experience and/or knowledge may use these devices, provided they are supervised or have
been instructed in the safe use of the device, and have understood the hazards involved. Children
must not play with the device.
No persons, objects, or animals are allowed within the range of the gate movement / barrier movement
during opening or closing.
Never reach into moving parts of the gate operator, gate or barrier.
Drive through the gate system /barrier only after complete opening.
The gate system / barrier has to be secured depending on the type of usage, corresponding to the valid
standards and regulations (e.g. safety at the main and secondary closing edges).
The safety devices have to be checked regularly for functioning according to the standards and
regulations, at least once a year.
2.3 Safety notes for the operation with radio remote control
The radio remote control should only be used, if the area of movement of the gate / barrier is always
completely visible by the operator and thus it is assured, that no person, object, or animal is present
within this range of movement.
The radio remote control transmitters have to be carefully kept, so that an unintentional use is
impossible.
Radio remote controls should not be operated at radio-technical sensitive locations, like airports or
hospitals.
Interferences by other (properly operated) radio communication installations, which are used within the
same frequency range, cannot be ruled out.
2.4 Intended use of barriers
The vehicle barriers model ES 50-80 are exclusively intended for controlling access to and exit of
certain road vehicles in or from certain areas.

5 Function description
Barriers serve as passage control of vehicle paths. By raising and lowering of the barrier boom the
passage is granted or obstructed.
For a boom length of 4,000mm and longer we recommend the use of a fixed or swinging support, for a
boom length of 5,000mm and longer the use of a fixed or swinging support is mandatory.
The controller offers the possibility to activate the barrier by radio remote control.
The controller is able to observe the max. permitted force which was set before in the learning
sequence. If during the closing movement more force is needed, the barrier reverses. Additionally
several different safety features, e.g. photoelectric barriers, can be connected.
Safety devices (photoelectric barriers, light curtains etc.) must be installed on site. The safety devices
and induction loops must ensure that the barrier danger area is clear before the barrier closes.

8 Installation ES 50 – ES 80
Basic requirements
 Keep a safety distance of min. 500mm between all moving barrier parts and surrounding objects
like walls, fences etc.
 When preparing the foundation consider the alignment and distance related to a (optional) fixed
support.
 The installation of barriers in flood areas is prohibited.
REMARK!
For the barrier foundation we recommend a concrete strength class of C20/25 (or higher) and the use
of chemical dowels (M12).
WARNING!
Risk of injury by insufficient fastening!
Tilting barrier housings can result in severe injuries.
 Before installation ensure a safe stand oft he barrier housing.
 Do not lean the barrier boom against a wall or similar before isntallation. Store the boom
horizontally only.
 Install the barrier housing as specified.
 Use the recommended heavy duty anchor bolts M12, at least M10 is required.
 During maintenance check the housing for a correct fasenting on the foundation.
1. Before preparing the foundation lay enough underground cable (provide for a sufficient number of
wires) or a plastic cable conduit for a later cable installation. The foundation has to be absolutely
frost-free and with a horizontal surface of 600 x 650mm (if possible, at least 30mm higher than the
surrounding ground).
Drawing 4
2. Using the provided template you can either grout bolts (min. 12mm) into the foundation at the
appropriate positions or drill holes into the hardened concrete for heavy-duty fixings. Secure the
barrier on its foundation. For a correct functioning make sure the barrier housing is in a
perpendicular position.
A
nchor the spring assembly with all four fastening points through the housing into the foundation (see
drilling template ).
3. To open (release) the barrier boom during installation and current failure, pull the release lever
(2). The barrier can now be opened manually. In the vertical position the bolt (1) engages
automatically. To close (reposition) the barrier boom pull the lever again and move the boom
manually downwards.
