Hardware error
The device will send this error message
if there is a microwave error, EEPROM
error (Config.), EEPROM error (HART) or
the current output is not calibrated.
—
Out of specification (NE 107 status signal)
Signal weak
The signal amplitude is less than the
average value. This can occur if the
liquid boils or if there is foam in the
bypass chamber. If this error occurs
frequently, the device will possibly show
the "No measuring value" error
message.
1
If this error occurs frequently, it is possible that you
must install a float with a radar target (if there is no
float supplied with the device).
Signal strong
This error can occur if there is a large
change in signal amplitude.
1
No corrective action is necessary.
Spectrum quality
bad
The quality of the spectrum is poor. If
this message is temporarily shown, this
will not affect the performance of the
device. If this message is continuously
shown, the measured values can be
incorrect. The error message
"Measurement old" will then be shown.
Possible causes are low reflectivity of
the liquid (if there is no float in the
bypass chamber) or the inner surface of
the bypass chamber is dirty.
Do a check of the device, bypass chamber and the
process. Change the device settings. If necessary,
contact the supplier.
Measurement old
This is a temporary error message. If the
device cannot get a measurement in this
time limit, the displayed measurement
is no longer correct. The voltage is
possibly too low. If the device continues
to show the message "Spectrum quality
bad", then this message is also shown.
Do a check of the voltage at the device terminals. Refer
also to the error message "Spectrum quality bad".
Maintenance (NE 107 status signal)
Sweep timing error It is possible that the device's hardware
is defective.
If this error message continues or occurs regularly,
replace the signal converter.
CPLD revision
mismatch
The CLPD software was not updated or
the device's hardware is defective.
Replace the converter. For more data, refer to
How to
replace the signal converter
on page 64.
Capacitor voltage
low
It is possible that the device's hardware
is defective.
Do a check of the power supply at the device terminals.
Make sure that voltage values are in the specified
limits. If the voltage is correct, replace the signal
converter.
Information
Current output set
to error
The device current output is at its error
value. The error value is set in the
Current output
Current output
Current output
Current output menu. For more data,
refer to
Current output
on page 54.
Do a check of the "Diagnosis" screen in the DTM to find
the problem. Then refer to the other errors shown in
this list. For more data, refer to
Diagnosis window
on
page 38.
Peak lost in tank
bottom
The tank is possibly empty. The device
will display the tank bottom
measurement.
If you fill the tank, the device will measure again.
Peak lost in
blocking distance
The level is in the blocking distance.
There is a risk that the product will
overflow and/or cover the device.
Remove some of the product until the level is below the
blocking distance.
