4 Fields of Application - What the LSI Can Do
These pages provide an overview of the key fields of application
of the LSI.
Area protection
On hazardous stationary machinery the LSI, in conjunction with
one or more PLS units, ensures that the machine (or its
hazardous movement) is shut down as soon as someone enters
the hazardous area. This is done by means of flexibly
programmable monitoring areas, each comprising a protective
field and a warning field, which are assigned to the connected
sensors for monitoring purposes. In the same way the LSI can
protect the interiors of large machines.
You can define various monitoring cases to match the active
protective fields to the situation on the machine and to monitor
different hazardous areas depending on the applicatio, such as
in different production phases.
Vehicle protection
You can deploy the LSI on vehicles, such as driverless transport
systems (DTS), forklifts and shunting cars, to safeguard a
vehicles path - on its way through a production hall for example.
The LSI with its connected sensors ensures that the vehicle
decelerates and stops if a person or obstacle is standing in the
way. You can protect both manually controlled vehicles and
driverless transport systems (DTS).
Several monitoring cases - defined by you - provide diverse
monitoring of various hazardous areas, such as when the vehicle
is moving forward and when reversing.
You can also record the speed of the vehicle by means of
incremental encoder, and so adapt monitoring areas of differing
sizes dynamically to the vehicle speed.
