MN300840 REV A5
LOOP FAIL-SAFE
This feature allows you to select the fail-safe current output if the
sensor looses echo confidence (LOST). When the sensor regains
echo confidence, the output current will revert back to the current level
condition.

Hold Last Value - The output will remain in the same state as
the last confident echo detected. Example: If the output was
6.7mA just prior to the lost signal, the sensor will continue to
output 6.7mA until echo confidence is regained.

Empty - The output will revert to the current value for an
empty condition. When 4 mA at Bottom is selected, the
sensor will output 4 mA during a fail-safe condition. If 20 mA
at Bottom is selected, the sensor will output 20 mA during a
fail-safe condition.

Full - The output will revert to the current value for a full
condition. When 4 mA at Bottom is selected, the sensor will
output 20 mA during a fail-safe condition. If 20 mA at
Bottom is selected, the sensor will output 4 mA during a fail-
safe condition.

Overfill (21mA) - The sensor will output 21mA during a fail-
safe condition.

Overfill (22mA) - The sensor will output 22mA during a fail-
safe condition.
OUTPUT AT EMPTY
This feature allows you to select the orientation of the 4 to 20mA
output (4 to 20 mA or 20 to 4 mA). Choose which output setting best
fits the application. Typical applications are set with 4 mA at Bottom.
Factory default is 4mA at bottom and 20mA at top. When connecting
your sensor to a display, you must account for your output orientation
setting.

4mA at Bottom - The output current will be 4mA when the
sensor measures an empty tank and 20mA when the sensor
measures a full tank.

20mA at Bottom - The output current will be 20mA when the
sensor measures an empty tank and 4mA when the sensor
measures a full tank.
