HB EML3020 A-(en)LevelWave LR01
_ Signal Weak 4 The signal amplitude is less
than the average value. This
can occur if the liquid is
agitated or if there is foam in
the tank. If this error occurs
frequently, the device will
possibly show the "Peak Lost
(Level Lost)" error message. 1
If this error occurs frequently, it
is possible that you must install
the device in a stilling well or
use a different antenna type.
_ Signal Strong 4 This error can occur if there is
a large change in signal
amplitude. 1
No corrective action is
necessary.
_ Bad Measurement Quality 4 The measurement is incorrect
and continues to be incorrect
after more than 10 s. This error
can occur if the tank contents
are immediately below the
antenna. 1
Record the process with the
PAC Tw a re ™ software tool to
find the cause of the problem.
If necessary, speak to the
supplier.
_ Temperature <-35°C/ -31°F 3 The process connection or the
ambient temperaure is less
than -35°C/ -31°F. T h i s
temperature is near to the
minimum limit for device
operation. 1
Measure the ambient
temperature. De-energize the
device until the ambient
temperature is back in the
given range. If the temperature
does not stay in the correct
range, make sure that there is
insulation around the signal
converter.
_ Temperature >+75°C/ +167°F 3 The ambient temperaure is
more than +75°C / +167°F.
This temperature is near to the
maximum limit for device
operation. 1
Measure the ambient
temperature. De-energize the
device until the ambient
temperature is back in the
given range. If the temperature
does not stay in the correct
range, make sure that there is
insulation around the signal
converter.

INFORMATION!
In 4.0.0 MASTER menu, the type of error shown for error codes 102, 201 and 203 can be
changed from "Error" to "Warning" (the NE 107 status signal changes from "Failure" to "Out of
specification"). For more data, speak to the supplier.
