Problem Fault Solution
ERROR MESSAGES
"Tank full" status marker on,
reading frozen at max or min
value
No fault. The level has reached (and possibly
risen above) the top configured measurement
limit and is either displaying the maximum
(when measuring level) or minimum (when
measuring distance) output.
None. Measurements should be normal
once the level is in the configured
measurement range.
"Tank empty" status marker
on, reading frozen at max or
min value
No fault. The level has entered the gauge's
bottom dead zone and can no longer detect
a return signal. Either the maximum (when
measuring distance) or minimum (when
measuring level) output is displayed.
None. Measurements should be normal
once the level is in the configured
measurement range.
"Tank full" and "Level lost"
status marker on, reading
frozen at max or min value
No fault. The level has entered the gauge's top
dead zone and can no longer detect a return
signal.
Empty the tank below the top
measurement range limit and check the
measurement.
"Level lost" status marker
on, reading is frozen
The instrument has lost the level signal, has
searched but not yet found the return pulse.
This may occur if the pulse has dropped below
the threshold. Parasite signals from the flange
or obstructions in the tank may render the
gauge unable to identify the correct signal.
Ensure that tank is emptied below
maximum level and check the
measurement. If the signal is not detected
then modify the control threshold
manually.
"Reference not found" status
marker on
Occurs when there is a problem with the time
base on the HF board.
Contact Bindicator for corrective
procedure.
"Level lost" and "Reference
not found" status markers
on, reading frozen
The probe has received an electrostatic
discharge.
The gauge will search for the level again
and resume readings. If reading remains
frozen then signal converter may have
been damaged by ESD and may need
replacing. Please contact Bindicator.
ELECTRICAL CONNECTIONS AND COMMUNICATION OUTPUT
Current Output value < 4 mA
No power supply. Check the power supply.
Connection of the device is incorrect.
Check the connection between the
device and the power supply.
The calibration of the current output is
incorrect.
Execute the calibration if you have
authorized access or contact Bindicator
Customer Support.
Reads 22 mA
An error has occurred.
This happens in case the range 4-20 mA/
error 22 mA is selected. Check the status
of the device by selecting the marker
window.
The device is in its start-up phase.
Wait 50 seconds. If the current value
drops to a value between 4 and 20 mA
and goes immediately back to 22 mA,
contact Bindicator
The value at the current
output does not correspond
to the value at the display
The current output settings are incorrect.
Check the current loop and the
connections.
Data communication via
the digital interface is not
working. The TDR-3000 is
in its start-up phase, wait 50
seconds and try again
The communication parameters of the
computer are set incorrectly.
Check computer setting (address/device
number).
Bad connection to the interface. Check connection.
Current output value is < 4 mA.
If problem persists then contact
Bindicator.
Current output value is = 22 mA.
