OPERATION
8.4.3
Automated adjustment of the interference signal limit
The adjustment of the interference signal limit (TrsHld) can be carried out automatically
in many applications.
Configuration
1.
Set a fill level of 30%.
2.
Log in to expert mode; see
.
3. Perform in the EXPRT-Pulse-AutoTn menu.
The sensor calculates a suitable value for TrsHld.
Note:
This setting can be used only in pulse mode.
8.4.4
Blanking the interference signals in the masked zone
To blank interference signals from the range above the maximum expected fill level,
a zone can be masked (dead zone). This zone begins at the process connection
and continues up to the configured point. If signal values above the defined limit
value (TrsHld) occur within this range, the sensor enters a safe state and signals the
error !MaskZ.
