Ultrasonic sensor with one ana-
logue output
Product Description
The pico+sensor offers a non-contact
measurement of the distance to an
object that has to be present within
the sensor’s detection zone. Depend-
ing on the set window limits, a dis-
tance-proportional analogue signal is
output.
The window limits of the analogue
output and its characteristic can be
adjusted with the Teach-in proce-
dure.
Two LEDs indicate operation and the
state of the analogue output.
Safety Notes
Read the operating instructions
prior to start-up.

accordance with the EU Machine
Directive
Proper use
pico+ultrasonic sensors are used for
non-contact detection of objects.
Installation
Mount the sensor at the installa-
tion site.
Connect a connection cable to the
M12 device plug.
Start-Up
Connect the power supply.
Carry out the sensor adjustment in
accordance with the diagram.

Synchronization
If the assembly distance falls below
the values shown in Fig. 2, the inter-
nal synchronization should be used.
For this purpose set the switched
outputs of all sensors in accordance
to the diagram »Sensor adjustment
with Teach-in procedure« at first.
Then set the multifunctional output
»Com« to »synchronization« (see
»Further settings«). Finally connect
pin 5 of the sensors plug of all sen-
sors.

chronization
Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend to clean the white
sensor surface.
Notes
The sensors of the pico+ family
have a blind zone. Within this
zone a distance measurement is
not possible.
The pico+ sensors are equipped
with an internal temperature com-
pensation. Due to the sensors self
heating, the temperature compen-
sation reaches its optimum work-
ing-point after approx. 20 minutes
of operation.
In the normal operating mode, an il-
luminated yellow LED signals the ob-
ject is within the adjusted window
limits.
If synchronization is activated the
Teach-in is disabled (see »Further
settings«).
The sensor can be reset to its fac-
tory setting (see »Further set-
tings«).
Optionally all Teach-in and addi-
tional sensor parameter settings
can be made using the LinkCon-
trol adapter (optional accessory)
and the LinkControl software for
windows© .
