1.24. Important safety rules
•
The SIS Easy anti-collision device is not a substitute for the operator manoeuvring vehicles forwards or in reverse.
Such vehicles must be driven and manoeuvred by personnel authorised to do so and adequately trained in
accordance with the applicable regulations.
•
Since the SIS Easy anti-collision device is merely an aid for manoeuvring a vehicle forwards or in reverse, the driver must
always look in the direction of travel, and make sure for himself that there are no hazards.
•
The Buyer/User is responsible for installing and setting up the SIS Easy anti-collision device. These operations must be
performed by fully qualified personnel whom the Buyer/User has ascertained to be in possession of the technical and
professional requirements.
The Buyer/User or the Fitter must consult the instruction handbook for the vehicle on which the SIS Easy anti-collision device
is to be installed, with specific reference to the wiring diagram, in order to identify the best branching point for the power
supply.
•
The SIS Easy anti-collision device is an aid for manoeuvring the vehicle. To get the maximum performance refer to the
maximum suggested veichle speed.
•
The choice of the preset must be compatible with the shape and configuration of the workplace.
•
While driving or manoeuvring a forklift truck on which an SIS Easy anti-collision device is mounted, it is mandatory to proceed
at a moderate speed to ensure that the vehicle can stop within the red band based on the speed settings.
•
The Buyer/User must provide the users of industrial vehicles using the SIS Easy anti-collision device with information and
training on the speed settings for the setted distances.
1.25. Identification of residual risks
No residual risks connected with the use of the SIS Easy anti-collision device itself have been identified.
There are, however, some residual risks associated with the use of the SIS Easy anti-collision device installed in an industrial vehicle.
The following factors may cause a hazard:
•
Incorrect behaviour while driving or manoeuvring the vehicle. Vehicle drivers must be informed and trained on how to use the
vehicles correctly and the risks associated with incorrect behaviour and failure to travel at the speeds required for the best SIS
system performance.
•
Failure to keept the sensor clean. An accumulation of dust and dirt on the capsules of the CySens transmitter and receiver
may generate interference with the ultrasonic signal transmitted/received, limit performance and reduce sensitivity.
•
Misuse and poor maintenance of the sensor. If the sensor signal transmission/reception capsules get crushed during cleaning
or maintenance, this will affect the quality of the signal received and, as above, limit performance by reducing sensitivity.
No part of the SIS Easy anti-collision device must be covered, as this would affect operation.
•
Wrong sensor position. If the transmission cone and receivers face downwards and are not positioned virtually parallel to the
ground, the sensor will only detect the ground, not the correct distance from any obstacles.
•
Interference with the surrounding environment. The presence of high ambient noise in the ultrasound wavelengths (e.g. with
ultrasonic machines) is likely to generate false alerts.
The diagrams below present a series of situations that could affect operation of the SIS Easy anti-collision device and cause a
hazard for the driver of the vehicle.
In Figure 5, which shows an obstacle covered by sound-absorbing material, the signal from the sensor transmitter is absorbed, so
the system is unable to detect the obstacle.
In Figures 6 and 7, the obstacles are out of range in terms of the height of the sensor, so the system cannot detect them. This is
why it is vital for the operator always to look in the direction in which the vehicle is moving.
Figure 8 shows the presence of a projection, which can deviate the ultrasonic signal emitted, preventing the device from detecting
the obstacle and the range.
