Operation
Setting the switching points
The switching points can either be user set (Teach-in mode)
with a measured object positioned at the corresponding dis-
tance or can be set using the setting input, for remote setting.
For each output of the sensor (up to two), up to two switching
points can be user set.
Only one switching point is active in the foreground and back-
ground suppression modes.
For the 2-point window evaluation mode, two switching points
must be set.
Teaching the switching points in the normal mode
The sensor is set at the factory for both outputs to
BGS
, light
on.
1. Place the target object in front of the sensor at the desired
position.
2. Teach the switching point for output 1:
• Beginning with the
key, press it simultaneously with the
ENTER
key. Threshold level is obtained and the output/
LED is updated. Status LED is blinking.
• Using the
/ keys an adjustment of the switching point is
possible. The output/LED is updated immediately.
• Pressing the ENTER
key for more than 2 seconds or af-
ter 2 minutes without any activation of the keys, the sensor
returns to normal operation. The status LED is turned off.
3. Teach the switching point for Output 2:
• Beginning with the key, press it simultaneously with the
ENTER
key.
Main menu structure
When the ENTER
key is pressed for 2 seconds, the sensor
switches from the normal mode to the TEACH menu path.
The sensor switches to each next menu path when the EN-
TER
key is repeatedly pressed for 2 seconds. In the menu
paths, the required parameters can be selected by pressing
and
keys.
To skip a menu path, you can also press the ENTER key
for 4 seconds.

LED display
The distance from the measured object and the names of the menu levels during set-up of the sensor are
displayed by the 4-digit 7-segment LED display.
The display appears as red digits or letters.
If the sensor is set to a bar chart display, the distance from the measured object is displayed as a green
LED bar chart.
