SICK LSI Technical Description - 06/98
9.6 Teach-in protective field
You can teach in protective fields. In the teach-in process the
active sensor runs over the space contour and the LSI
generates a protective field on that basis. You can influence the
extent of the protective field by running a target board over it, for
example. You have to check learned protective fields.
You can also edit a learned protective field subsequently, just
like any other segmented field (function not available for use of
LSI with PLS 101-316).
•
From the Active Field list select the protective field you
want to edit.
•
From the Active Sensor list select the sensor from which
you want to receive data.
•
From the menu choose
Monitoring Area - Teach-in
.
•
Or click on the Teach-in Monitoring Area button on the
toolbar.
The active sensor scans its surroundings and shows you the
results. The contour you see on-screen is the largest possible
extent of the protective field (the precise contour of the
protective field is based on the ambient contours).
•
If you want to reduce the size of the learned contour, run a
target (e.g. a piece of cardboard, at least 10 x 10 cm in size)
slowly along the edge of your desired protective field.
The contour of the protective field is reduced at the relevant
point. On the screen you can track how the protective field takes
on the taught-in contour.
Note:
To prevent fixed obstacles in the scanning plane subsequently
producing false signals, 13 cm (= max. measuring error of PLS)
is automatically deducted from the learned contour. Take this
into account as appropriate when running over the protective
field.
Also note that the teach-in process may result in an additional
error of 4.5 cm.
•
To terminate teach-in, deactivate the Teach-in Monitoring
Area button.
