Designated use
The Festo Checkbox has been designed for use under normal
operating conditions in enclosed work rooms in industrial
applications.
The Checkbox Compact described in this manual is intended
exclusively for use as follows:
For contactless checking of the position and quality of small
conveyed parts such as e.g. screws, springs, bolts.
Use the Festo Checkbox only as follows:
– in accordance with designated use
– in faultless technical condition.
– without any modifications by the user.
No guarantee claims can be accepted if the device is opened.
Laser radiation
The Checkbox Compact is a device of laser class 2 as per
EN 60825-1:1997 (class II as per CFR 21 §1040.10, USA).

Notesontheuseofthismanual
This manual refers to the standard designs of the Checkbox
Compact Classic (type CHB-C-C) and Compact PLC (type
CHB-C-P) with operating system version 3.x.
When the Checkbox is switched on, the version number of the
operating system will be displayed briefly (see chapter 2.4).
The options and parameters available depend on the operat-
ing system, the type of Checkbox connected and the pre-set-
tings made at the factory. Special customer-specific designs
may differ in technical data, parameter settings and function-
ality.
The pre-setting of the Checkbox can be modified if required
with the software packages CheckKon (function “Modify sys-
tem”) or CheckOpti (see chapter 1.2).

Good part A test part on which all features lie within the tolerances.
Laser class 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).
Teach procedure 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.”

Term/abbreviation Meaning
Features Characteristic features are ascertained from the contour data of the
sample and test parts. These are, e.g. length, height etc., as well as a
feature for each configuration tool (CheckOpti).
Scatter of characteristics The value range of a feature ascertained from several parts.
Sample parts Good parts selected for the teach procedure which show all features
necessary for identifying the parts type.
Orientation The parts to be checked by the Checkbox may lie in different align-
ments on the conveyor belt. During the teach procedure, you can
define the orientations by showing the different alignments.
Orientation 1 is the preferred orientation (nominal orientation).
(System) parameter Checkbox settings (in some cases settings can only be made with
configuration software)
Test d a t a Thetestdataarethedatausedforthetest.Thesecorrespondtothe
teach data plus the specified tolerances.
Te st p a r ts All parts shown during the test process.
Test p roc e dure During the test procedure, test parts on the conveyor belt are shown
to the Checkbox and classified according to their features with regard
to orientation and observance of tolerances. This is also referred to as
“Testing parts.”
Bad part A test part on which at least one feature lies outside the tolerances.
Teach data All features ascertained during teaching, in each case with min./max.
limits and average value.
TEACH mode Operating mode of the Checkbox in which the teach procedure is
carried out.
Parts type Conveyed part defined by the teach data of the sample parts.
Tole ranc e Factor in percent related to the average values and which has an effect
on the min./max. limits of all the features.
