Measurement status
Level measurement lost E 1 The device can no longer find
the product surface. The
measurement is held at the
last measured value.
Check the tank contents
using another method of
measurement. If the tank is
empty (the level is below the
end of the probe), then fill the
tank until product level is in
the measurement range. If
the tank is full (the level is in
the blocking distance), then
remove the contents from the
tank until the level is back in
the measuring range. If the
product was lost and the tank
is neither full nor empty,
contact your supplier.
When the level return signal
and the probe end return
signal are lost. This is
applicable to automatic
(Direct/TBF) measurement
mode only.
If the device is in direct mode,
adjust the Level Threshold
(menu item C.1.16). If the
device is in TBF mode, adjust
the Probe End Threshold
(menu item C.1.18). For more
data, refer to Thresholds and
parasitic signals on page 92.
Level measurement low W The product is 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.
The product is outside the
measuring range. The
measurement is incorrect or
held at the last measured
value by the device.
Measurement old E This error can occur if the
power supply is not sufficient
to operate the device
correctly for 1 minute. After 1
minute the error message
"Measurement old" is
recorded. You can change this
time in supervisor mode. Go
to Advanced Setup > Output Advanced Setup > Output Advanced Setup > Output Advanced Setup > Output
1 > Error Handling Delay 1 > Error Handling Delay 1 > Error Handling Delay 1 > Error Handling Delay
(5...300 seconds).
Make sure that the power
supply for output 1 has a
min./max. value of
14...30 VDC (20...36 VDC for
Ex d-approved devices) when
current output is at 22 mA.
Interface measurement lost
2
W 1 The device can no longer find
the interface.
Check the tank contents
using another procedure. If
the interface is too low (the
interface is below the end of
the probe), then fill the tank
with interface product until it
is in the measurement range.
If the interface too high (the
interface is in blocking
distance), then remove the
contents from tank until the
interface is back in the
measuring range. If it is none
of these two, then there is
possibly an emulsion at the
interface. Wait for the device
to find the interface again.
