10.15.2 Module 91 – AutoReflAct (automatic reflector activation)
Description
The module defines the mode of operation of the laser scanner for controlling the reading
gate.
The AutoReflAct function uses the scanning beam to simulate a photoelectric sensor and
thus permits an activation without additional sensory mechanism. 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 reflector, the reading gate remains
closed. If, however, the reflector is blocked by an object such as a container with a barcode
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.

Debouncing
The parameter defines the
debounce time in scans for
the reflector detection
With a motor speed of
1000, 1 scan corresponds
to a debounce time of
