LED display
The sensor displays information about the operation state when
the LEDs are lit or flashing. The information is divided into
groups as follows:
Normal operation:
The output signal of the sensor is displayed. The LEDs flicker/
light up depending on the position of the material web within
the sensor field of view.
Error message:
Error n = 1 .. 3:
The output signal of the sensor (10s long) and the flashing
pattern of an error are displayed alternately. An error is
displayed until it has been corrected. It is still possible to use
the sensor.
Error n = 4 .. 7:
Only the blinking pattern of an error is displayed. The sensor is
no longer supplying a valid output signal.
Fault
In the event of an error, the LEDs flash with a certain pattern:
flash n times for 0.5s on - 0.5s off, followed by 1s pause.
The number of flashing pulses between two pauses encodes the
error number "n".
