Defective sensor assembly
Cause
Incorrect wiring
Faulty wiring or poor
contact
Cause
Incorrect default file used.
The default file length does
not match the actual sensor
length.
The electronic board is not
communicating with the
sensor assembly. No
measurement data available.
This may be due to a faulty
connection, faulty cable, or
failure of the sensor
assembly.
Polls or requests are issued
from the LevelMaster
application to the unit
successfully, but correct
measurements are not
received back.
Solution
Connect the board to
the sensor assembly or
verify that the
connector is properly
attached.
Replace sensor
Solution
Verify pinouts, correct wiring
or ensure wires are inserted
securely in the connectors
(tighten terminal connector
screws to ensure there are no
lose wires).
Solution
Locate the default file for the
length of the unit and
download the configuration.
Click Re-read to verify the
new configuration yields
correct measurements.
Ensure the electronic board
sensor port (16-pin port) is
connected to the sensor
assembly cable. Ensure the
cable connector has
snapped into place and is
securely attached.
Click Re-read to verify the
problem is cleared.
