ERR 100 Device reset 1 The device detected an internal
error (watchdog timer issue).
Record the data that is in menu
item 2.2.2 DIAGNOSTIC
(Configuration mode /
Supervisor menu). Speak to the
supplier.
ERR 101 Current Output Drift 1 The current output is not
calibrated.
Speak to the supplier to get the
calibration procedure.
1 Hardware error. Replace the device.
ERR 102 Temperature out of
range
1 The ambient temperature is
outside the given range. This
can cause loss or corruption of
data.
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. If this error occurs 2
times, replace the device.
ERR 103 Converter memory
failure
1 The device's hardware is
defective.
Replace the signal converter.
For more data, refer to How to
turn or remove the signal
converter on page 35.
ERR 104 Converter Voltage

1 The device's hardware is
defective.
Replace the signal converter.
For more data, refer to How to

Communication
1 The device's hardware or
software is defective. The
converter cannot transmit
signals to or receive signals
from the antenna electronics.
De-energize the device. Make
sure that the signal cable
engages in the terminal and the
screw connection is tight.
Energize the device. If the
problem continues, replace the
signal converter. For more data,
refer to
How to turn or remove
the signal converter on page 35.
ERR 201 Overfill 2 The level is in the blocking
distance. There is a risk that the
product will overflow and/or
cover the antenna.
Use a different procedure to
measure the level in the tank.
Remove some of the product
until the level is below the
blocking distance.
If a viscous product touched the
antenna:
• remove the device and clean
the antenna, or
• If the device has a purging
option, use the purging system
to clean the antenna.
ERR 203 Peak Lost (Level
Lost)
2 The signal peak is not found
within the measuring window
that filters the signals received
by the antenna. The
measurement is not correct.
The device will automatically
increase this window to find the
correct signal.
Do a check of the device, tank
and the process. Reconfigure
the device and record a new
empty spectrum. Follow the
instructions on page 75. If
necessary, speak to the
supplier.
