of activating special operating modes of the devices.
WARNING
Prior to the commencement of work, each operator
(pedestrian, truck and station) must make sure that
ELOshield operates correctly by checking its correct
functionality – a test interaction of each ELOshield
module and combination of modules must be evoked in
order to trigger an alarm.

Instruction manual I ELOshield
Rev. 20 09.03.2020 Page 7 of 85
1.2 Electromagnetic wave radiation
As specified in the international standard ISO 14117:2012, the ELOshield electronic radio warning
system operates in the frequency band of over 3 GHz and does not constitute a hazard to human
life in accordance with their intended use.
ELOshield is intended to protect pedestrians (a pedestrian module), vehicles (a vehicle module) and
zones (a stationary module). The system may also be used to create industrial automatic control
systems reacting to an approaching/receding object.
1.3 Operation of ELOshield
Each person to whom a vehicle constitutes a potential threat must be equipped with the pedestrian
module. Each vehicle which is meant to detect pedestrians/vehicles/stationary zones must be
equipped with a vehicle module with antenna modules (A) (1-4) creating two protective zones
around the vehicle. Locations that are especially hazardous or require additional interactions with
vehicles/pedestrians must be secured using a stationary module with antenna modules (B) (1–4)
and stationary modules (1–4). Examples of such locations include crossings with heavy traffic or
entrance gates.
Each person/vehicle within the protective zone (span of the zone: up to 12 m for vehicles, 12 m for
pedestrians) is detected by the system. Entering the zone triggers pre-configured actions of the
vehicle or stationary infrastructures.
Example actions of the vehicle include: acoustical alarm, optical alarm, speed reduction and even
breaking down the vehicle.
By proper configuration of the stationary module, vehicles and/or persons within the range of the
stationary zone may trigger the following actions: opening of the entrance gate, change the state of
traffic lights, vehicle speed reduction within the range of the stationary zone, stopping a vehicle
entering an area where the pedestrian is present, etc.
The actions performed by the pedestrian module in an emergency situation include: a visual signal,
acoustic alarm, vibration.
The alarm/warning may be muted by pressing the Q button.

5. Use and operation of the pedestrian module and charger
The pedestrian module is used to warn about a potential threat from a vehicle equipped with
ELOshield. The protection is realized by generating broadband electromagnetic pulses with ultra-
low power.
WARNING
Risk due to signal disruption!
The water content of the human body can influence radio signals, either
preventing or limiting the function of ELOshield.
 Only wear the pedestrian module on the upper arm area.
 Always check that the ELOshield is working before starting work.
 ELOshield should only be viewed as an assistance system.
 The attention of all participants to the surroundings must always be
maintained.
CAUTION
Radio radiation!
Radio radiation is released due to the use of ELOshield.
• Other devices could be disturbed and their function impaired.
• Please check with the manufacturer of pacemaker or other medical devices,
whether disturbance cannot be excluded.
CAUTION
Beware of electrical voltage and heat!
Touching live parts can result in injuries. Also, a short circuit can occur which
causes components to be heated. This can lead to injuries.
 The power supply must be disconnected when working on electrical
components.
 Metal objects such as rings or watches must be removed beforehand.
 Connection, testing and measuring work on electrical parts may only be
carried out by a qualified electrician.
 If the electrical parts are faulty or damaged, turn off the electrical power
supply immediately and initiate repair.

Instruction manual I ELOshield
Rev. 20 09.03.2020 Page 17 of 85
DANGER
Electrical voltage hazard.
Touching live parts can result in death. Damage to insulation or individual
components can be life-threatening.
 The power supply must be disconnected when working on electrical
components.
 Metal objects such as rings or watches must be removed beforehand.
 Connection, testing and measuring work on electrical parts may only be carried
out by a qualified electrician.
 If the electrical parts are faulty or damaged, turn off the electrical power supply
immediately and initiate repair.
 The regulations of the local energy supplier must be complied with.
5.1 Operating modes
 Normal – the default operating mode, when the device is switched on. Active warning and
alarming for all threat types.
 Driver’s muting mode – It may be activated by short-pressing the Q button, when the
pedestrian module is within the muting zone range. This mode is designed for a vehicle
operator and used to mute the pedestrian module, when the operator drives the vehicle, so
as not to block its vehicle and other vehicles, as the vehicle is used. In this mode, the
pedestrian module becomes invisible to all vehicles, and stops alarming and warning about
threats. The visibility is restored, as the driver zone is exited by a driver. The driver zone must
be small enough to cover only the inside of the vehicle with its range.
Driver muting is only available with at least 2 antenna modules (A).
DANGER
 Note that a different person than the driver can mute his pedestrian module,
especially, if vehicle muting zone is too large.
 The acknowledge mode – It may be activated/deactivated by pressing the Q button for 2
seconds and is used to mute the alarm in the pedestrian module. Alerts in vehicles will still
be active. The mode will be automatically deactivated as conditions deteriorate (when a new
threat appears in the proximity) or when the configurable period of time elapses – from 0
seconds to 18 hours.

Instruction manual I ELOshield
Rev. 20 09.03.2020 Page 18 of 85
5.2 Q button
 When pressed – the device is switched on (if switched off), auto-test is completed or the
driver’s muting mode activating. The driver’s muting mode may be switched on, when the
pedestrian module is within the muting zone reach. The muting zone is configured from the
application level in vehicle module.
 When pressed and held for 2 seconds – activate/deactivate the acknowledge mode.
 When pressed and held for 5 seconds – power off (signaled with vibrations)
