parts e.g. screws, springs, bolts, which pass through on a
conveyor belt.
Use the Checkbox only as follows:
– as intended in an industrial environment
– in perfect technical condition
– in original status without unauthorised alterations. Only
the conversions or modifications described in the docu-
mentation supplied with the product are permitted. The
guarantee will become invalid if the Checkbox is opened.
The maximum values specified for pressures, temperatures,
electrical connections etc. must not be exceeded.
Please observe the standards specified in the relevant
chapters and comply with the regulations of the trade associ-
ation and the German Technical Control Board (TÜV), the VDE
conditions as well as the relevant national regulations.

Laser irradiation
The Checkbox is a device of laser class 2 according to
EN 60825-1:1994 + A1:2002 + A2:2001 (Class II according
to CFR 21 §1040.10, USA), but contains a laser of class 3B.
Therefore, observe the following:
• Do not open the device.
• Do not remove any housing parts (e.g. prism support,
covers).
• Operate only with intact housing.
Avoid injuries to the eyes due to laser irradiation. Observe
the following rules for working with lasers of class 2:
• Do not bring any mirrors or reflecting items into the laser
beam.
• Never stare into the laser beam and never direct the
bean into the eyes of other people.
• If the laser beam hits the eye, consciously close your
eyes and move your head out of the beam.
Work with laser devices is subject to accident prevention
regulations. Users must be instructed on the risks of look-
ing directly into the beam.

Conventions
– The names of the operating, display and connecting
elements are represented in the text in upper case letters,
e.g. START, TEACH.
– Menu commands of the software are framed in brackets,
e.g. in the menu [Window], the command [System parame-
ters] opens the window for creating parameters.
– For selections within tree structures, e.g. for setting the
system parameters in CheckKon, the paths are marked
with a square. You will therefore find e.g. in the path
ZSystem ZOperating modes the parameter zLock the
Teach button = Off.
– Inputs and outputs of the plug connectors are specified
with the pin number as follows:
Input pin 1 I/1
Output pin 2 O/2
– Plug connectors are represented as when viewed on the
device. This representation corresponds to the view of the
(cable) connections which are to be wired.

Notes on the use of this manual
This manual refers to the standard designs of the Checkbox
Compact type CHB-C-X with operating system version 3.x.
When the Checkbox is switched on, the version number of the
operating system will be shown briefly (see Chapter 2.5).
The options and parameters available depend on the
operating system, the type of connected Checkbox and on the
factory pre-settings. Customer-specific designs may differ in
technical data, parameter settings and method of functioning.
The pre-setting of the Checkbox can be modified if required
with the software packages CheckKon (function “Modify
system”) or CheckOpti (see Chapter 1.2).

Term/abbreviation Significance
AUTO mode Operating mode of the Checkbox for automatic parts testing
(pre-set when CHB-C-X is started).
CHB-C-X A device of the type Checkbox Compact (without transporting device) for
identifying conveyed parts of a parts type.
C-value During the Teach procedure the C-value shows the extent of the
scatter of characteristics of the sample parts. The C-value specifies
the maximum value of the scatter of characteristics for the current
feature which differs to the greatest extent.
Deviation The Checkbox assesses the feature of an inspection part which differs
most from the Teach data. The smaller the value of the inspection part
deviation, the more accurately the inspection part corresponds to the
sample parts.
Feature Characteristic features are ascertained from the contour data of the
sample and inspection parts. These are e.g. length, height, etc. as well
as a feature for each configuration tool (CheckOpti).
Good part An inspection part on which all features lie within the tolerance.
Inspection parts All parts shown during the test procedure.
Laser class Labelling of the laser beam according to EN 60825-1:1994 + A1:2002
+ A2:2001. Laser devices are classified according to increasing degree
of danger into classes 1, 2, 3A, 3B and 4.
Class 2
An accidental, brief exposure (up to 0.25s) will not damage the eye.
With longer lasting exposure, damage to the eye is possible.
Laser devices of class 2 may be used without further protective meas-
ures, providing it can be guaranteed that during operation the user is
not required to look intentionally over a long period (longer than
0.25 s), or to look repeatedly into the laser beam or mirror-reflected
laser beam.
Class 3B
Lasers of class 3B can produce serious eye damage.
Longer radiation of a class 3B laser onto the skin causes erythema
formation (reddened skin), pigmenting, burns or photochemical
damage.

Orientation The parts to be tested by the Checkbox can be placed on the conveyor
belt facing in different directions. During the Teach procedure you can
define the orientations by showing the different directions. Orientation
1 is the preferred orientation (nominal orientation)
Parts type Conveyed part defined by the Teach data of the sample parts.
Reject part An inspection part on which at least one feature lies outside the
tolerance.
Sample parts Good parts which have been selected for the Teach procedure and
which possess all the features necessary for identifying the parts type.
(System) parameters Settings of the Checkbox (in some cases can only be set with
configuration software)
Teach data All features ascertained during the Teach procedure, each with
min./max. limits and the average value.
TEACH mode Operating mode of the Checkbox in which the Teach procedure is
carried out.
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”.
Test data Thetestdataarethedatausedforthetest.Thesecorrespondtothe

Test procedure During the test procedure, inspection parts on the conveyor belt are
shown to the Checkbox and graded according to their features with
regard to orientation and observance of the tolerances. This is also
referred to as “Testing parts”.
