4 Support beam location
5 Silo bottom signal
6 Support beam signals (interference signals) before the device does the empty spectrum scan
7 Signal of the solid before the device does the empty spectrum scan
8 Reflected signal if the device uses the data from the empty spectrum scan. The device only uses the reflection on the
surface of the solid to measure distance.

6.5 Status messages and diagnostic data

Device status and error messages are shown on a device status page in Normal mode and in
menu item "C7.3.1 Messages View" in Program mode. Messages shown agree with NAMUR
Guidelines NE 107. The error messages for the device are divided into status groups, each with
one status signal. There are 16 status groups with fixed status signals and 8 groups with status
signals that can be changed. The status groups are also divided into 4 groups: Sensor,
Electronics, Configuration and Process.
Each status message (or status signal) has a special symbol which agrees with the NAMUR
Guidelines. This symbol is shown with the message.
