5.14.2 Typical application errors
Error
The transmitted value takes a value from
a close range (most often around 0.2 m).
The measured value does not change
despite the level change.
Explanation
The type of the primary transmitted value (PV) by P01a
The device is in manual programming mode
(Only on devices featuring a display)
The device is in remote programming mode
The device is in simulation mode.
Caution! The output value is independent of the measured value
Password protection is active
Relay is energized
User lock is active. The parameters are protected by a password set
by the user
Factory lock is active. The factory default settings and calibration
data are locked
A display is connected to the device (Only on devices featuring a
display)
The device is in diagnostic mode
The transmitted value is on hold
The device is in calibration mode
The transmitted value is refreshed and valid
The device is in high-speed communication mode
Possible cause
Condensation or dirt on the antenna.
This typically happens when echo loss
occurs. In most cases, this is:
during foaming of the medium
•
dirt on the antenna
•
excessive waves
•
incorrect max. (P03) measurement
•
setting
it can happen in cases of echo below
•
the threshold curve
Type 2298 80 GHz Radar Level Sensor
Solution
Clean the antenna or use a threshold
mask to block the interfering echo.
Remove dirt from the antenna. Check the
surface of the medium to be measured, if
necessary, take measures to reduce
foaming or ripples!
Check threshold settings.
Check the P03 maximum measuring
distance setting.
