Ä Select a response timet
a
of 80ms or higher.
Never define a value higher than 80ms for t
a
for access guarding or passage controls. With higher val-
ues it can happen that a person might not be detected when passing through the protective field with
an approach speed of 1600mm/s.
Ä Determine the machine/system's stopping timet
m
.
If data is not available, you can commission Leuze electronic to perform measurements (see chapter
14 "Service and support").
Ä If an increase in the stopping time within the regular test periods is to be expected, take an additional
time into account for the machine's stopping timet
m
.
Additional distanceC
RT
for finger protection
The required finger protection is ensured here by an additional distance C, which depends on the safety
sensor resolution, in addition to the safety distance.
• Detection of an adult's hand:
• Resolution: 30mm
• Additional distance C
RT
: 128mm
• Arm detection:
• Resolution: 40mm
• Additional distance C
RT
: 208mm
Protective field contour and reference contour
With a vertical protective field, you must define at least two sides of the protective field contour as refer-
ence contour. The objective is to monitor the position of the protective field with regard to its marginal area.
If the arrangement misaligns and the distance of the safety sensor to the reference surface changes as a
result, switch the safety-related switching outputs off.
Ä When defining the protective field ensure that there are no gaps bigger than 150mm.
Ä When defining the protective field boundaries, specify the sectors that monitor the position of the pro-
tective field as reference contour.
7.5 Mobile danger zone guarding on AGVs
Danger zone guarding protects people and objects that are in rooms in which vehicles move in, e.g. auto-
mated guided vehicle systems (AGVs).
A horizontally arranged protective field protects people and objects that are in the vehicle's path and are
detected by the front edge of the protective field.
WARNING
Danger of injury because of insufficient vehicle stopping distance
Ä The operator of the machine must use organizing measures to prevent people from entering
the protective field of the vehicle from the sides or being able to move towards an approach-
ing vehicle.
Ä Only use the safety sensor on vehicles with electrical drive and electrically influenced drive and braking
devices.
Ä Only install the safety sensor on the front of the vehicle.
If you must also guard the reverse travel, you must also install a safety sensor on the rear of the vehi-
cle.
Ä Mount the safety sensor on the vehicle so that there are no unmonitored areas ≥70mm between the
protective field and vehicle front.
Ä Set the mounting height such that the beam level is not more than 200mm above the floor.
A person lying on the floor can therefore be safely detected. This is required by the C standard,
EN1525 "Safety of industrial trucks – Driverless corridor supply vehicles and their systems".
NOTICE
The beam level of the safety sensor is level with the alphanumerical display.
