When the stability safety margin is indicated, "P" is always displayed.
Two methods of displaying incoming light level on the digital display
can be selected.
Normal display (initial mode): Displays the current incoming light
level (red) and the set value (green)
Stability safety margin indication: The letter P (green) and the ratio
(in %) if the incoming light level (red) to the detection threshold are
displayed.

The current consumption can be decreased about 30% if the display
will be turned off. A green moving point in the display shows that the
sensor is still working in normal operation.
If using the display-off function, the display changes to energy
saving mode after 20 seconds.

4.6 Self threshold adjustment STA
This function automatically adjusts the detection threshold using a
given ratio of the threshold to the incoming light level. The auto-
adjustment of the threshold is carried out at regular intervals

to a combination of the sensor and a diffuse scan fiber unit or a slow

Option settings allow a combination of automatic sensitivity
switching saving to EEPROM and enabling/disabling STA reset.
EEPROM storage: Settings modified by STA are stored in

EEPROM. When the function is enabled settings are stored in
EEPROM. When function is disabled settings are not stored in
EEPROM. If writing to EEPROM would be very frequent, select
"disabled" (durability: approx. 200'000 erase-write cycles).

Response times for Fr-2 differ from those for Fr-1.
Press
The emitter LED frequency can be selected from Fr-1 and Fr-2
(when "normal" or "semi fast" is selected). Even if fiber units are next
to each other, mutual interferences can be prevented for up to 2
units by selecting different frequencies.

5. Behavior if an error occurs during Teach-in
If an error occurs while teach-in (e.g. insufficient contrast, insuffi-
cient light level), it will be indicated on the display and the switching
output remains at 0V.
The switching output remains at 0V until another successful teach-in
has been carried out or the failed teach-in has been manually
acknowledged using the "FUNC/CANCEL" button.
