ELECTRICAL CONNECTIONS AND COMMUNICATION OUTPUT
Current Output value < 4 mA
Reads 22 mA
The value at the current
output does not correspond
to the value at the display
Data communication via
the digital interface is not
working. The TDR-3000 is
in its start-up phase, wait 50
seconds and try again
TDR180003 Rev. I
Fault
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.
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.
No fault. The level has entered the gauge's top
dead zone and can no longer detect a return
signal.
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.
Occurs when there is a problem with the time
base on the HF board.
The probe has received an electrostatic
discharge.
No power supply.
Connection of the device is incorrect.
The calibration of the current output is
incorrect.
An error has occurred.
The device is in its start-up phase.
The current output settings are incorrect.
The communication parameters of the
computer are set incorrectly.
Bad connection to the interface.
Current output value is < 4 mA.
Current output value is = 22 mA.
Solution
None. Measurements should be normal
once the level is in the configured
measurement range.
None. Measurements should be normal
once the level is in the configured
measurement range.
Empty the tank below the top
measurement range limit and check the
measurement.
Ensure that tank is emptied below
maximum level and check the
measurement. If the signal is not detected
then modify the control threshold
manually.
Contact Bindicator for corrective
procedure.
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.
Check the power supply.
Check the connection between the
device and the power supply.
Execute the calibration if you have
authorized access or contact Bindicator
Customer Support.
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.
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
Check the current loop and the
connections.
Check computer setting (address/device
number).
Check connection.
If problem persists then contact
Bindicator.
