Description
The simulation mode is active. The given
measurements are simulated.
The advanced simulation mode is active.
The given lower volume value is invalid.
The given upper volume value is invalid.
The probe end projection is active in the
transmitter software.
An echo has been detected in the
reference zone.
This may result from various
measurement problems, such as:
• Rapid level changes
• Surface level within Blind Zone
• Disturbing echo
An echo has been detected in the
nearzone.
The nonlinear gain is enabled.
The current sweep can be used as a
measurement of the nearzone.
Description
The interface measurement is not OK.
No interface available
Interface threshold to high
Interface cannot be measured when the
probe is horizontally mounted.
Service and troubleshooting
Action
Turn off the simulation mode.
To turn off the Advanced Simulation
mode, set Holding Register 3600=0 (see
View/edit holding registers).
Check Lower Volume Status for details.
Check Upper Volume Status for details.
No action needed.
No action needed.
Check the tank to find out what causes
problem to track the surface.
• Set the Rapid Level Changes
parameter, see Rapid level
• In the Blind Zones, the level may jump
to Full Tank/End of Probe
• See Disturbance echo handling.

Action
Check other interface status messages
for reason.
No action needed.
Adjust Interface threshold, see
2: Interface peak not found.
Change the probe mounting or turn off
interface measurement by changing the
measurement mode.
