Output pulse extension
Switching the function input (PK) on to -U
B
or +U
B
makes it possible to select
a minimum pulse width of 120 ms for all output pulses of the three switch out-
puts.
Please note:
This can result in a condition in which more than one switch output is switched
through!

Display mode
The selected parameter assignment of the sensor can be displayed by swit-
ching the function input (PK) to voltage-free during normal operation. The
green LED displays the program number (the number of flashing pulses (1 ...
4) = the program number).
The outputs are inactive at this time.
If the function input (PK) is unconnected when power is supplied (Power-On),
the sensor will also work in display mode (green LED flashes).
If the function input (PK) breakes due to an error while the device is in normal
operation mode (broken cable, coming loose because of vibration), display
mode acts as a fault display (green LED flashes).
6.5
Parameter assignment
The sensor is equipped with 4 programs for different ranges of application.
This makes it possible to work with a wide range of material. The user can se-
lect the program best suited for a specific application.
The default setting, Program 1, is designed so that no change in the set-
ting is required for most applications.
