6.
To set the total fluid level offset, enter a value of
1
for the top float and then enter the
offset value. If the value is less than one, enter the decimal value, then press “Enter.”
7.
To set the level offset for the bottom float, enter a value of
2
for the bottom float, then
enter the offset value, and press “Enter.”
8.
To verify that the offset is correct, return to the main screen and then read level and
temperature values to verify the DLS is reading correctly.
9.
Once the level offsets are entered, there is no further calibration required unless the DLS
is removed and reinstalled in
another
tank.
Testing and Troubleshooting
If the sensor fails to respond or does not report an accurate level, several things could be at fault. See the
list of common issues below for help in diagnosing the problem.
Sensor does not respond:
Sensor is new and recently installed:
1.
The sensor wiring is incorrect: check the sensor connection (hook-up) diagram.
2.
Wrong baud rate: (Factory default is 9600)
3.
Wrong protocol: (Factory default is N81)
4.
There is insufficient voltage: The sensor needs at least 5.6 VDC.
Sensor has been in service for some time but is not working:
1.
There are corroded connections or damaged cables.
2.
Blown fuse or shorted suppressor on the barrier board (if equipped). Check the fuses
with a continuity tester.
3.
There is possible damage to sensor electronics.
Sensor sends inaccurate level or temperature:
1.
An incorrect level or temperature offset is programmed into sensor, RTU, or host.
2.
An incorrect number of floats are programmed. Check the sensor protocol list to
reprogram the sensor with the correct information.
Sensor sends temperature but no valid level:
1.
If the sensor reports error code 1, the float is not on the sensor in the correct
orientation. The white mark on the float must be on top of the strip on the side of
the sensor.
2.
An incorrect number of floats are programmed. Check the sensor protocol command
list to reprogram the sensor with the correct information.
