4.3 Incoming light level display
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.
4.4 Monitor sleep mode
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.
4.5 Display inversion
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
(approx. every 3 s). When STA is enabled, the STA indicator is lit. If
the threshold is not adjusted due to the incoming light level fall in
below the limit, the indicator blinks. When STA is enabled, neither
manual tuning nor auto-tuning is possible. If STA will be used, check
its operation in advanced. If the incoming Light level fluctuates due
to a combination of the sensor and a diffuse scan fiber unit or a slow
work piece speed, STA may fail to adjust the threshold to the
expected one.
4.7 Option
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).
4.8 Emitter frequency switching
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.
