Module 92 - Autocontrol - Leuze electronic BCL 248i Operating Instructions Manual

Starting up the device - Configuration
The autoReflAct function uses the scanning beam to simulate a photoelectric sensor and thus permits an
activation without additional sensors. This is achieved by directing the scanner with reduced scanning
beam towards a reflector mounted behind the conveyor path. As long as the scanner is targeted at the re-
flector, the reading gate remains closed. If, however, the reflector is blocked by an object such as a con-
tainer with a bar code label, the scanner activates the read procedure, and the label on the container is
read. When the path from the scanner to the reflector has cleared, the read procedure has completed and
the scanning beam is reduced and again directed onto the reflector. The reading gate is closed.

8.15.3 Module 92 – AutoControl
PROFINET-IO module identifier
Module ID: 1092
Submodule ID: 1
Description
The module defines the mode of operation of the function AutoControl. The function monitors the quality of
the decoded bar codes and compares these with a limit value. If the limit is reached, a status is set.

Leuze electronic GmbH + Co. KG
Description
This parameter activates the
function of the diffuse laser sen-
sor. If "Autom. reading gate con-
trol" is set as the parameter
value, the BCL activates the
reading gate automatically if the
reflector is obscured.
The parameter defines the de-
bounce time in scans for the re-
flector detection. With a motor
speed of 1000, 1 scan corre-
sponds to a debounce time of
1 ms.
Description
This parameter can be used to acti-
vate or deactivate the AutoControl
function
