2 Safety

This chapter concerns your own safety and the safety of the BAS users.

▸

Please read through this chapter carefully before using the BAS or the vehicle

monitored by the BAS.

2.1 Qualified personnel

The BAS must be installed, commissioned, and maintained only by adequately qualified

personnel.

A qualified person

• has sufficient skills in the field of the respective equipment based on their technical

training and experience and

• has been instructed by the manufacturer in system operation and all applicable safety

guidelines and

• is familiar with all relevant country-specific occupational safety regulations, work safety

regulations, guidelines, and generally accepted technical rules and standards (e.g.,

DIN standards, VDE regulations, country-specific rules) to such an extent that he/she

is able to evaluate the safe condition of the power-operated equipment, and he/she

• has access to and has read the operating instructions.

2.2 Applications of the system

The BAS (Backup Assistance System) is a driver assistance system that monitors the

blind spot behind a manned forklift truck and other industrial vehicles with a 2D-LiDAR

sensor and thus minimizes the risk of collisions.

When reversing, the system warns the driver of the vehicle via acoustic signals when the

vehicle is too close to a stationary or moving object. A signal column for visual warning is

also optionally available.

The BAS was designed specifically for manned forklift trucks and can be connected to the

reverse drive function of the vehicle to eliminate false alarms.

The driver assistance system is designed for installation in manned forklift trucks or other

industrial vehicles. Different versions are available for vehicles with different voltages and

electrical systems.

The BAS detects only objects which are visible in the measurement plane for the 2D

LiDAR sensor. Therefore, the 2D LiDAR sensor must have a free view of the area to be

monitored.

Use of the retrofittable stand-alone solution makes it possible to reduce accidents and

damage, and the driver can concentrate on the current tasks being performed.

The BAS is a driver assistance system. This means that at all times the driver bears the

full responsibility for safe operation, in particular for people who are in the hazardous

zones of the vehicle.

OPERATING INSTRUCTIONS | BAS

WARNING

System does not comply with safety standards

The BAS is not suitable for the protection of persons according to the applicable safety

standards for machines. The system therefore does not comply with safety standards.

The BAS is a driver assistance system. It provides the driver of manned forklift trucks or

other industrial vehicles with acoustic and, where applicable, visual warnings about

objects outside the field of view when backing up. The steering system of the vehicle is

not overridden.

At all times the driver bears the full responsibility for safe operation, in particular for

people who are in the hazardous zones of the vehicle.

2.4.3 Potential hazardous points

Laser radiation

WARNING

Damage to the eye by laser beam

The 2D LiDAR sensor TiM3xx used in the BAS conforms to laser class 1 (eye-safe) in

accordance with ((EN 60825-1:2014), eye-safe).

The laser operates at a wavelength of γ = 850 nm (invisible infrared light). The laser beam

is not visible to the human eye.

The radiation emitted in normal operation is harmless to human skin and eyes.

Improper use (e.g., opening the housing and stopping the motor) can result in dangerous

exposure to radiation.

▸

Never open the 2D LiDAR sensor housing. Opening the housing does not interrupt the

operation of the laser beam.

▸

Pay attention to the laser safety regulations as per EN 60825-1:2014 (latest version).

• No maintenance is required to ensure compliance with laser class 1.

• The laser output aperture is the window of the 2D LiDAR sensor.

Electrical current

HAZARD

Risk of injury and damage caused by electrical current

Improper handling of live devices may lead to severe personal injury or death by electric

shock.

▸

Electrical installation and maintenance work must always be carried out by personnel

authorized to do so.

▸

The power supply must be disconnected when attaching and detaching electrical

connections.

▸

Select and implement wire cross-sections and their correct fuse protection in accordance

with the applicable standards.

▸

Do not touch any live parts.

▸

In the event of danger, immediately disconnect the object detection system from the

power supply.

▸

Always use original fuses with the specified current rating.

▸

Report any damaged cables to the maintenance team without delay.

▸

Observe the up-to-date safety regulations when working on electrical systems.

HAZARD

Damaging potential equalization currents due to different ground potentials

BAS has been designed and tested for electrical safety in accordance with EN 60 950-1

(2006-04) and EN 60 950-1/A11 (2009-03).

It is connected to the peripheral devices via shielded cables. The cable shield (e.g. supply

cable) is connected to the metal housing of the TiM3xx. The device can either be

grounded through the cable shield or through both fastening clips.

If the peripheral devices have metal housings and if the cable shields also are connected

to these housings, it is assumed that all devices contained in the system have the same

ground potential.

This is achieved, for example, by complying with the following conditions:

• Mounting the devices on conductive metal surfaces.

• Properly grounding the devices and metal surfaces in the system.

• Low-impedance and current-carrying equipotential bonding between areas with different

ground potentials, if necessary.

If these conditions are not met, e.g., on devices in a widely distributed system over several

buildings, potential equalization currents may, due to different ground potentials, flow

along the cable shields between the devices and create hazards.

Potential equalization currents between the TiM3xx and other grounded devices in the

system can have the following effects:

• Dangerous voltages on the metal housing, e.g. of the TiM3xx

• Incorrect function or irreparable damage to the devices

• Damage/irreparable damage of the cable shield due to heating and cable fires

▸

For smaller installations with only slight potential differences, the insulated installation

of the TiM3xx and of peripheral devices may be a sufficient solution.

3.2 System components

TiM3xx 2D LiDAR sensor

A TiM3xx 2D LiDAR sensor installed on the roof or rear of the industrial vehicle

continuously monitors the ground behind the vehicle in a radius of up to 8 m from the

sensor while the vehicle is backing up. The monitored area depends on the sensor type

used.

The 2D LiDAR sensors of the TiM series are based on the laser scanner principle and use

time-of-flight measurement. 2D LiDAR sensors scan their surroundings by emitting a laser

pulse which they then direct in the required direction using a moving mirror.

The laser beam is emitted through the front screen. The scan plane position is indicated

by a housing marking next to the front screen.

Fig. 3: Scan plane of the TiM3xx

When the laser pulse hits an object in the scan range, it is reflected and sent back to the

receiver of the 2D LiDAR sensor. By calculating the time difference between sending and

receiving and also the signal strength, the position of the object is detected with

millimeter accuracy.

Fig. 4: Position determination with TiM3xx

2D LiDAR sensors have one specific task in “detection” applications, namely to detect

whether or not an object is located in a defined scanning field. Switching outputs deliver

the result “object in field” or “object not in field” within fractions of a second.

Detection scanners are therefore often used to prevent vehicle collisions. These non-

contact laser scanners scan the environment and keep track of important objects at all

times. If there is a risk of a collision, the scanners can be relied upon to output a warning

via the switching outputs prior to an accident occurring.

Control unit with relays and power supply unit

The control unit comprises a power supply unit, three relays and a terminal block. The

control unit is installed in the control cabinet of the industrial vehicle.

• The power supply unit (1) is connected to the voltage supply of the industrial vehicle.

The power supply unit acts as the central voltage supply for all connected system

components of the BAS driver assistance system.

Different power supply units are available for vehicles with different voltages and

electrical systems.

• The driver assistance system is controlled via three relays (2). Two relays process the

incoming signals of the 2D LiDAR sensor and forward the processing result by means

of an I/O signal to the acoustic signal generator (and optionally to the signal column).

The third relay processes the vehicle signal for reversing. Different versions are

available for vehicles with different voltages and electrical systems.

• All system components of the BAS driver assistance system are connected with each

other via the terminal block (3) upon delivery.

Tone buzzer

A tone buzzer warns the driver about obstacles.

OPERATING INSTRUCTIONS | BAS

3.3 Operating principle

BAS is a driver assistance system for manned forklift trucks and other industrial vehicles.

Using a 2D LiDAR sensor, the system warns the driver when the vehicle is too close

to a stationary or moving object.

Monitoring fields

As the factory setting, the monitoring field scanned by the 2D LiDAR sensor is divided into

the two monitoring fields Warning and Stop. If an object is detected in one of the fields,

an acoustic warning is issued for the driver to reduce the speed or stop the vehicle

immediately.

The size and geometry of the monitoring fields can vary and must be configured

correspondingly during commissioning.

Switching signals for object detection

Each monitoring field is assigned to a switching output of the 2D LiDAR sensor. In the

event of a field violation, the switching signal is forwarded to the responsible relay. The

relay processes the incoming signals of the 2D LiDAR sensor and forwards corresponding

results such as “Warning field violation” or “Stopping field violation” to the acoustic signal

generator (and to the signal column, where applicable).

Fig. 9: Switching signals of object detection

In order to avoid false alarms, the driver assistance system can be configured so that the

signals from the 2D LiDAR sensor are taken into account only when the vehicle is reversing.

The reversing signal is processed by one relay.

Acoustic (and visual) signaling of field violation

The BAS driver assistance system warns the driver acoustically and (in conjunction with

the optionally available signal column) also visually.

A prerequisite for visual signaling is that the reversing signal is active. The signal column

lights up green in this case.

Fig.. 10: Acoustic (and visual) signaling of field violation

• Violation of the warning field is indicated acoustically by means of an intermittent

warning tone. The signal column lights up yellow (when the reversing signal is active).

• Violation of the stop field is indicated acoustically by means of a continuous warning

tone. The signal column lights up red and yellow (when the reversing signal is active).
