The display
reading does not
change and the
current output
value is incorrect.
2 ERR 200 Reference
pulse lost
Reference amplitude
is less than reference
threshold. This fault
could occur because
the device hardware is
defective.
Contact your supplier to check
that the electronics are still
functioning correctly.
1 ERR 201 Sensor
voltage failure
The device's hardware
is defective.
Contact the supplier.
The display
reading does not
change and the
current output
value is incorrect.
4 ERR 202 Level lost
error
The device cannot find
the product surface.
Measure the level of the contents
in the tank 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,
wait for the device to find the level
again.
The device cannot find
the level return signal
Refer to MEAS. AMP. (Measured
Pulse Amplitude, menu item
2.5.6) and then adjust MEAS.
THRESH. (measurement
threshold, menu item 2.5.7).
The measurement
and the current
output value stops
at the "full" value.
4 ERR 204 Overfill error The tank is full. The
level signal is lost in
the full area. The
measurement stops at
the blocking distance
value.
Danger of overflow! Remove the
contents from the tank until it is
at a safe level.
The measurement
stops at the last
measured value
and the current
output value is
incorrect.
3 ERR 205 Measurement
old
This error occurs if
the power supply is
not sufficient to
operate the device
correctly for
approximately 30
seconds. After 1
minute the error
message
"Measurement old" is
recorded.
Make sure that the power supply
has a min./max. value of
14...30 VDC when current output
is at 22 mA.
3 ERR 206 No sensor
detected
This error occurs if
there is a problem
with the power supply.
Contact the supplier.
1 Defective wiring.
1 ERR 207 Sensor
