Alarm Threshold
An
Alarm Threshold
can be set for soiling detection. The
value range is 20%...90%. If the light reception level
normalized to the 100% reference falls below the alarm
threshold, the event
Maintenance Required – Cleaning
is
output and the Device Status is also set to
1 –
Maintenance Required
. In this case, the front lens of the
sensor or the reflector should be cleaned.
Current Receiver Level
The
Current Receiver Level
parameter is used to output
the currently available reception level to the reflector,
referenced against the 100% reference. The parameter is
thus a value for the current degree of soiling of the sensor.
If no valid measurement value is available after switching
on the sensor, the value of 255 is read out.
