7.4 Error conditions
The device can sense the error conditions in the table that follows. When the device detects a
measurement error, it supplies an output current at the error signal current value.
Error condition
Device does not start
immediately
The current output is incorrectly
calibrated
Component hardware errors
Ambient temperature is too high
Ambient temperature is too low
Incorrect measurement signal
(e.g. level lost)
Overfill
For more data, refer to the "Status and error messages" section in the handbook (document
[N1]).

Initial state (new measurement)
Cause
This error occurs if more than 20 seconds are necessary to start the
device.
Do a current output check. For the procedure, refer to
check
on page 31. If the values do not agree with the tolerances given
in the procedure, speak to the supplier.
Memory failure
Voltage failure
No signal
Microwave failure
The ambient temperature is more than +80°C / +176°F.
The ambient temperature is less than -40°C / -40°F.
The signal peak is not found within the measuring window that filters
the signals received by the antenna. The measurement is not correct.
The level is in the blocking distance. If menu item 2.5.3 OVERFILL EN.
is set to "YES", there is a risk that the product will overflow and cover
the antenna.
