Stationary Horizontal Guarding—Up to Four Safety Zones
Stationary Vertical Guarding—Two or More Safety Zones
The SafeZone multizone safety laser scanner can be mounted to
create up to four vertical detection areas in the same plane. Contour
as a reference should be configured to prevent manipulation of the
scanner. A static control input switches between the configured
fields.
Automatic Guided Vehicles (AGVs)
The SafeZone safety laser scanner is designed to detect fixed
objects (walls, columns), as well as moving objects (people, AGVs ).
The SafeZone safety laser scanner is typically mounted on the front
of a mobile vehicle or for AGVs capable of bi-directional travel, in
each direction of travel. Any object in the path of the moving
vehicle, of sufficient resolution, is detected. When an object or
person is detected in the configured warning field, a signal can be
used to decrease the speed of the AGV. Intrusion into the safety
field will send a signal to the AGV to stop. It is also possible to
configure a predetermined time delay where the SafeZone safety
laser scanner will monitor the safety field. If the safety field becomes
clear, the SafeZone’s Output Signal Switching Device (OSSD) will
change to a green state and allow the AGV to continue traveling.
The SafeZone multizone safety laser scanner can be configured with
up to four field sets; each set may consist of a warning zone and a
safety zone. If the application warrants, it may only be necessary to
configure the safety zone(s).
Note: Both the SafeZone singlezone and multizone can be used in
mobile applications, depending upon safety field range requirements
and the required number of switchable pre-configured field sets.
