2 Foreword
BLAXTAIR® is a pedestrian’s detection device for industrial
vehicles.
Combined with usual safety practices, it will help you to improve
the safety in the vicinity of dangerous industrial, earthmoving or
mining machines by providing relevant and reliable information
to the driver.
In order to get the best from this high-tech equipment
implementing a breakthrough technology, and before starting
using BLAXTAIR®, it is strongly recommended to read this
manual. It indicates the precautions, scope of use and basic
maintenance procedures of BLAXTAIR®, to maintaining the
equipment at its best level of performance.
BLAXTAIR® is designed to providing the
operator with additional information which
could help them when manoeuvring. It is not
an alarm system and it does not reduce the
responsibility of the operator or his/her
manager in case of a collision. BLAXTAIR® is designed to
supplement the usual safety practices already implemented. It
must be integrated into a comprehensive safety policy taking
into account the risk factors that are specific to the activity of
the company.
Vehicle control and safety of operations remains the
responsibility of the Operator and the authorities in charge.
BLAXTAIR® does not detect pedestrians lying on the ground.
BLAXTAIR® is not designed to detect small objects. As with
any detection system, an object or a pedestrian may not be
detected.
The current version of BLAXTAIR® does not detect squatting
pedestrians.

Most collisions between industrial vehicles and
pedestrians occur when setting off or after a
sudden change of direction.
BLAXTAIR® is optimized to provide pertinent
information to the driver during these critical phases.
When the vehicle is operational, it is the driver’s responsibility
to adapt the speed to the environment and remain observant
at all times.
BLAXTAIR® is not designed to detect pedestrians when the
vehicle is travelling at high speeds.
Each year plant accidents result in the loss of life, significant
personal injuries and damages to products and property. Most
plant accidents are the result of driver error.
Basic operator training should be carried out
prior to operators using any equipment
installed with BLAXTAIR® systems. Followed
by periodic training to ensure awareness of
usage and limits.
Optimal performance of a BLAXTAIR® systems is subject to
the compliance with recommendations for use and
maintenance as described in this manual.
BLAXTAIR® shall not be interfaced with the
command or control devices of machinery.
Output signals of BLAXTAIR® shall not be
used for controlling automatically, directly or
indirectly, machinery control devices.

4.2 Installation and start
Your BLAXTAIR® system has been installed by an authorised engineer.
To remain operational with optimal performance, the equipment should not be
disconnected or moved. The positioning of the sensor head(s) and processing
unit(s) have been set to achieve the best possible performance and the
system has been calibrated accordingly.
As soon as the driver switches on the vehicle, the BLAXTAIR® system starts
automatically.
The processing unit emits a ‘beep’ after 5 seconds (+/- 1 second) to confirm
power up.
The picture below shows the different screens that aresuccessively displayed
by the monitor during the initialization process.
The system performs a ‘self-test’ sequence. Once all the ticks of this page turn
green, the video is displayed on the monitor, with a green boarder, and the
LED (if installed) will turn green indicating that Blaxtair system is now fully
operational.

Do not shut down the processing unit during initialisation. The complete
initialisation process can last from 30 to 70 seconds.
The frame displayed on the screen is green if BLAXTAIR® is operational AND
does not detect any danger.
If the frame is red, the BLAXTAIR® is operational and
detecting obstacles or pedestrians.
If the frame is orange, the BLAXTAIR® requires
calibrating.
If there is no frame, the BLAXTAIR® is initialising.
If the frame is purple, the BLAXTAIR® has a problem. Please contact
the after sales service.

When the ignition is turned off the BLAXTAIR® system will automatically shut
down (similar to a laptop). A delayed shutdown option is available and may
have been set up by the installation engineer.
Do not disconnect the power supply (e.g. battery isolator) of the vehicle until
the BLAXTAIR® system has shut down.
4.3 Maintenance operations
4.3.1 Starting the machine: verification of
detection
At the beginning of each working day, before starting working with a vehicle
equipped with BLAXTAIR®, the operator should check that the BLAXTAIR®
is operational. Below is a more detailed procedure to verify correct operation
during the usual periodic checks of the machine.
Before performing the test, the operator should ensure that all safety
conditions are fulfilled and that he/she won’t endanger anyone. With the
assistance of a second person, the driver should carry out the following
procedure:
•Park the vehicle in a flat open area, surrounded by barriers. Make
sure that the vehicle cannot move;
•Draw the detection area on the ground;
•Turn on the ignition without starting the engine;
•Wait until the camera view is displayed on the screen and its frame
(and LED if fitted) is green;
•Make sure that the vehicle cannot move then engage reverse gear,
or any other signal needed to enable detection;
•Ask the assistant to move across the detection zone. Check that
the system detects the pedestrian as soon as they are inthe danger
area. The screen frame should turn red immediately and the alarm
should sound as long as they stayor move within the detectionarea;
•If the test fails, contact Blaxtair hotline.

4.3.2 Sensor head cleaning (at least once a day)
To ensure optimum performance, both lenses of the sensor heads should be
cleaned at least once a day (If the mirrors need cleaning, so will the sensor
heads!).
Clean the lenses at least once a day with a soft cloth. Products for washing
windows and water may be used.
After cleaning, make sure that the windows are:
•Dry, free of dirt and drops;
•Without scratches. In case of significant scratches, contact your
installer or Blaxtair’s customer support.
4.3.3 System setup (if necessary)
During installation, the system was set up for optimum performance.
If the sensor head has been moved from its initial position or suffered an
impact, performance will be degraded.
If the sensor head has received an impact of any kind,
the system must be checked ref: section 4.3.1 .
It in any doubt the system must be inspected by a
Blaxtair certified engineer.
4.4 Driver Periodical training
Before working with a machine equipped with BLAXTAIR®, operators should
be specifically trained as to its use and maintenance.
He/she shall be updated on a regular basis regarding:
•His/her own responsibilities (see warning. chapter 2);
•System operation and limitations (chapter 4);
•Precautions for use (section 4.1);
•Maintenance operations he/she is responsible for (section 4.3).

The mirror display mode is enabled or not during installation, according to the
positioning of the sensor head.
5.3 Detection/danger area
The detection area (also called danger area), has been defined by your
installer according to your needs and constraints.
It is generally composed of two separate sub-zones:
•an « obstacle » sub-zone where any obstacle, pedestrian or not,
triggers an alarm;
•a « pedestrian » sub-zone where only pedestrians trigger alarms.
5.4 Alarm trigger
The BLAXTAIR® System is unique in its ability to detect only pedestrians
Combined with the set detection zones, only active in the direction of travel,
it dramatically reduces the constant ‘nuisance’ alarms encountered by other
systems
The alarm will only sound if there is a person in the ‘Pedestrian Zone’ with
the option of a small ‘Obstacle Zone’ to protect the rear of the vehicle, if
required
The main complaint expressed by operators is of constant warnings emitted
by so called ‘safety systems. Apart from the fact that an operator will choose
to ignore these constant alarms they can also cause mental fatigue which can
lead to loss of concentration, promoting the likelihood of accidents as opposed
to reducing them.

Example of obstacle detection: red frame and warning icon. In the top
right corner, a radar view shows the detection zone (in red) and the
approximate position of the detected obstacle (white dot).
RED = DANGER
THE DRIVER SHOULD STOP THE VEHICLE IMMEDIATELY!
After having stopped the vehicle, and before moving again, the
driver should identify the cause of the alarm and check carefully
that there are no pedestrians or obstacles in the danger area.
