SICK LSI Technical Description - 06/98
As a check, click on Overview. This will show you the
monitoring cases with the associated sensors, fields and
speed ranges.
(In the example five monitoring cases are defined: three for
forward at different speeds, and two for reverse. The
monitoring cases forw1 and rev1 are active
simultaneously (simultaneous monitoring cases), and protect
the vehicle in both directions at slow speeds.)
Edit monitoring areas: Define the shape and size of the
various protective and warning fields for your application, as
described in sections 9.3 and 9.5.
Further tips and hints:
In section 11.1 you will find a number of examples of
applications with further options for implementing your on-
vehicle application in a configuration with incremental sensors.
Section 9.8 describes how you can simulate monitoring cases
on PC to check the assignment of the sensors and fields at
various speeds.
In section 9.10 you will find information on the I/O Monitor
menu function, with which you can receive and log the switching
states of the inputs and outputs and of the incremental sensors
from the LSI during operation.
A note about turning on-the-spot:
For turning on-the-spot, the directional information delivered by
the two incremental sensors differs. Under normal
circumstances this would cause the LSI system to shut down.
You can enable turning on-the-spot by defining a Turn
monitoring case as follows:
The Use speed range option is deactivated for this
monitoring case. The data of the incremental sensor are
then not evaluated during turning. In the overview (see
diagram) the entire speed range of the vehicle is then
highlighted.
Apart from the incremental sensors, one other input must be
configured, e.g. input A, with the sole function of activating
the Turn monitoring case. This input must be set to
0 = low in all other monitoring cases.
