ACCESSORIES FOR LIGHT BARRIERS
Pulsating-light amplifier WLV3
The pulsating-light amplifier pulses the transmitter diode of the light barrier. The signal detected by the receiver element
of the light barrier is amplified and synchronously evaluated.
All sensors of GLS series can be operated in combination with the pulsating-light amplifier WLV3. The output of the
pulsating-light amplifier provides a signal that gives information about the switching state of the light barrier (unfree/
free).
Features:
Technical data:
w Pulsating-light operation increases the insensitivity of
the connected light barrier to outside light and dirtying
(synchronous evaluation).
w The sensitivity can be set by means of a potentiometer
w LED switching output indicators
(red: unfree / green: free)
w Switching mode: dark-switching / bright-switching
w NPN or PNP output
w Yellow LED as indicator for dirtying

Comment
Setting
Turn potentiometer 3 turns in clockwise
direction (+direction).
Minimum detectable segment width: 0.3 mm
(depends on the fork light barrier or blow-air fork
light barrier used).
Turn potentiometer 3 turn in clockwise
direction (+direction).
Then turn it 1.5 turns in anticlockwise
direction (-direction).
WLV is more insensitive to dirtying:
minimum detectable segment width: 0.5 mm
(depends on the fork light barrier or blow-air fork
light barrier used).
Turn potentiometer 3 turns in anticlockwise direction (-direction).
WLV is extremely insensitive to dirtying:
minimum detectable segment width: 0.7 mm
(depends on the fork light barrier or blow-air fork
light barrier used)

Dark-switching
PNP output:
In case of the PNP output the load is connected to GND at the
output line. If an event occurs, the PNP output transistor
switches the output through to plus, which results in a current
flow through the load resistor. This type of control logic is called
minus-switching.

+24V
GND
NPN output:
The electronic unit has a transistor output; the load lies
between the plus pole of the supply voltage and the
output line, which is switched through to GND by the
output transistor (NPN transistor), if an event occurs.
This output is also called plus-switching.
