Table of Contents

If a distance measurement cannot be performed, a replacement value/ default value is output. Possible causes that the sensor cannot supply a measured value:

  • The measuring object is outside the measuring range.
  • The light signal received from the sensor is not strong enough.
  • The laser is switched off.
  • An error has occurred (in an error state the output ist 0 mA / 0 V)

The sensor behaves as follows:

FW Analog output Minimum distance undershot Maximum distance exceeded Signal too weak/ Laser off
V1.0 4 - 20 mA, rising (Default) 3.5 mA 20.5 mA 20.5 mA
4 - 20 mA, falling 20.5 mA 3.5 mA 3.5 mA
0 - 10 V, rising 0 V 10 V 10 V
0 - 10 V, falling 10 V 0 V 0 V
V2.2.0
V2.2.1		 4 - 20 mA, rising (Default) 3.5 mA 20.5 mA 20.5 mA
4 - 20 mA, falling 3.5 mA 3.5 mA 20.5 mA
0 - 10 V, rising 0 V 10 V 10 V
0 - 10 V, falling 0 V 0 V 10 V
V2.2.2 4 - 20 mA, rising (Default) 3.5 mA 20.5 mA 20.5 mA
4 - 20 mA, falling 20.5 mA 3.5 mA 3.5 mA
0 - 10 V, rising 0 V 10 V 10 V
0 - 10 V, falling 10 V 0 V 0 V

Please note: The behavior of the analog output in case of undershooting of the minimum distance or a too weak signal had changed in the "falling" state for FW V2.2.0 and V2.2.1 (SN 20340001 - 21130923)

Fix with FW V2.2.2 (SN 21130924)
