3.3 Electronics
The sensors must be connected in a voltage-free state (U
V
= 0 V). The information in
the graphics [B] must be observed, depending on the connection type:
–
Male connector connection: pin assignment
– Cable: wire color

Only apply voltage/switch on the voltage supply (U
V
> 0 V) once all electrical connec‐
tions have been established. The green LED indicator lights up on the sensor.

3.4 Functioning of the programmable input
Value Notes
PNP mode Deactivated < 5.0 V Also deactivated when not connected
Active > 10.0 V Max. applied voltage not higher than
UV
NPN mode Deactivated > 10.0 V Max. applied voltage not higher than
UV
Active < 4.0 V Also active when not connected
The programmable input must be active for the durations specified below (e.g., U
> 10.0 V in PNP mode ) in order to set the corresponding functions. For a description of
the available functions and how to select them via the menu, see "Setting the analog
output, switching output, and other sensor configurations via the menu", page 9
Function Minimum duration Maximum duration
Laser shutdown 4 ms -
External teach-in Q1 4 ms -
3.5 Alignment
Align the sensor with the object. Select the position so that the red emitted light beam
hits the center of the object. You must ensure that the optical opening (front screen) of
the sensor is completely clear [F]. We recommend making the adjustments using an
object with a low remission.
