Meaning
The Checkbox assesses the feature of a test part which differs most
from the teach data. The smaller the value of the test part deviation,
the more exactly the test part corresponds to the sample parts.
Operating mode of the Checkbox for automatic parts test (preset
when the Checkbox is started).
A device of type CHB-C...(Checkbox Compact) in the design Classic or PLC
A device of type CHB-C-C (Checkbox Compact Classic) for identifying
conveyed parts.
A device of type CHB-C-P (Checkbox Compact PLC) for identifying
conveyed parts. Additional connections for a higher-order controller
and encoder.
The C-value indicates the extent of the scatter of the features
of the sample parts.
A test part on which all features lie within the tolerances.
Identifying the laser radiation as per DIN EN 60825-1:1997
Laser devices are classified according to increasing degree of danger
in the classes 1, 2, 3A, 3B and 4.
Class 2
The eye is not damaged after a brief random influence (up to 0.25 s).
Long-term influences may cause damage. Laser devices of class 2 may
be used without further protective measures, providing it can be as-
sured that for the application neither intentional long viewing (longer
than 0.25 s) nor repeated viewing of the laser beam or mirror reflected
laser beam is necessary.
Class 3a
Comparable danger as with laser devices of class 2. When used with
convex optic instruments (magnifying glasses, telephoto lenses, tele-
scopes), damage comparable to that caused by class 3B can however
occur (damage to eyes and skin).
During the teach procedure, sample parts on the conveyor belt are
shown to the Checkbox and the features are scanned. This is also
referred to as "Teaching parts."
