Interface measurement low
2
W The product is lost in the
empty area. The
measurement is held at the
sensor length.
Fill the tank to at least the
bottom of the measuring
range to continue
measurement.
Layer measurement low 2 W The layer is less than 50 mm /
2¨ thick.
Fill the tank with top product
until it is at least 50 mm / 2¨
thick.
Signal status
Reference pulse low
amplitude
W Reference amplitude is less
than reference threshold 1.
This fault could occur
because of electrostatic
discharge in solid
applications.
Make sure that your
installation has ESD
protection. For more data,
refer to Installation on page
17.
Reference pulse lost E Reference amplitude is less
than reference threshold 2.
This fault could occur
because the device hardware
is defective.
Make sure that your
installation has ESD
protection. For more data,
refer to Nozzles on conical
silos on page 34.
Contact your supplier to
check that the electronics are
still functioning correctly.
Level pulse lost W This shows that the device
lost the level signal in direct
mode but finds the signal for
the end of the probe. It will
continue to measure level in
tank bottom following (TBF)
mode. This warning is only
displayed in automatic
measurement mode.
The device continues to
measure in TBF mode. If the
device does not measure
correctly, make sure the
amplitude of the level
threshold is correct. For
more data, refer to
Thresholds and parasitic
signals on page 92.
Probe end pulse lost W The probe end pulse
amplitude is less than the
probe end threshold. This
means the device cannot find
the probe end to measure
level in TBF mode. The device
uses direct mode as an
alternative to TBF mode. This
error is only displayed in
automatic measurement
mode.
The dielectric constant of the
tank contents is too high.
Check that the Measurement Measurement Measurement Measurement
Mode Mode Mode Mode (menu item C.1.13) is
set to Direct Direct Direct Direct or Automatic Automatic Automatic Automatic.
Operating status
Overfill W 1 The tank is full. The level or
the interface signal is lost in
the full area. The
measurement is held at the
blocking distance value.
This is also used for
applications with WHG
approval. Danger of overflow!
Remove the contents from
the tank until it is at a safe
level.
