Evaluation of the reading quality

NOTICE

Output of the reading quality

The bar code positioning system can diagnose the reading quality from the arrangement of the
BPS relative to the bar code tape.

Ä

The reading quality is displayed in % values.

Ä

In spite of optimum operating conditions, the reading quality may be slightly below 100%.
This does not indicate a defect of the BPS or of the bar code tape.

NOTICE

The warning threshold preset ex works for a reading quality < 60% as well as a switch-off
threshold for a reading quality < 30% corresponds to Leuze's experience in a typical application.

For applications that involve an intentional interruption of the bar code tape (switches, expan-
sion gaps, vertical slopes/descents), the preset limit values can be adapted to the respective ap-
plication.

The reading quality is dependent on several factors:

• Operation of the BPS in the specified depth of field

• Number of bar codes in the transmitted beam

• Number of bar codes in the reading field

• Soiling of the bar code

• Traverse rate of the BPS (number of bar code symbols within the time window)

• Ambient light incident on the bar code and on the optics (glass exit window) of the BPS

The reading quality is affected, in particular, in the following cases:

• Switches, expansion gaps and other transition points at which the bar code tape is not affixed interrup-

tion-free.

• Vertical travel if at least three bar code symbols are not completely in the reading field of the sensor at

any given point in time.

• Vertical curve in which the bar code tape was separated at the marked cut marks for adapting to the

curve.

NOTICE

If the reading quality is influenced by the factors listed above, the reading quality can be re-
duced to as low as 0%.

Ä

This does not mean that the BPS is defective, but rather that the reading quality characteris-
tics are reduced to as low as 0% in the given arrangement.

Ä

If, at a reading quality of 0%, a position value is output, it is correct and valid.

The parameters for the evaluation of the reading quality are set via the webConfig tool:

CONFIGURATION

>

DATA PROCESSING

>

Reading quality

(see chapter 9.3.4 "CONFIGURATION

NOTICE

The values of the reading quality are displayed via the optional display (

Quality

), the serial com-

munication protocol and via the webConfig tool (see chapter 9.3.3 "ALIGNMENT function").

The evaluation of the reading quality provides the following information, e.g.:

• The reading quality is constantly bad: Soiling of the BPS optics

• The reading quality is always bad at certain position values: Soiling of the BCB
