just prior to the lost signal, the device will continue to output
6.7 mA. Sensor will indicate the level when signal was
regain.
oEmpty - 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 when a fail-safe condition occurs.
If 20 mA at Bottom is selected, the sensor will output 20 mA
when a fail-safe condition occurs.
oFull - 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 when a fail-safe condition occurs. If 20 mA at
Bottom is selected, the sensor will output 4 mA when a fail-
safe condition occurs.
oOverfill (21mA) - The output current will go to 21mA when
the return signal is lost.
oOverfill (22mA) - The output current will go to 22mA when
the return signal is lost.
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 installations are set with 4 mA at

Wiring Diagram
Sample Wiring Diagram –Use WebCal to view appropriate wiring diagram
Wire Connections:
Red & Black
Red and Black leads are for connection to a 24 VDC power supply or to a 4-20 mA loop power
source. The red and black wires can be extended up to 1,000 feet using a 22 gauge or larger wire,
however do not extend the green and white wires.

31 MAR 11 EchoPod 19 of 29
Rev B MN204210
White & Green
White and Green leads are reserved for use with WebCal and should not be connected during usage
in the application. These wires should not be connected to WebCal while power is supplied from
any source other than the LI99 series Fob.
Never allow the white or green wires to touch any power supply.
Blue, Orange, Yellow & Purple
Blue, Orange, Yellow & Purple wires are the relay contacts (normally open) from each of the relays
respectively. Relay selection is determined by the configuration in WebCal.
Brown
The Brown wire is the common for all the relays.
General notes for electrical connections, usage and safety:
Where personal safety or significant property damage can occur due to a spill, the
installation must have a redundant backup safety system installed.
Wiring should always be completed by a licensed electrician.
Supply voltage should never exceed 28 VDC.
Always use stepper relays between the sensor and external loads. For DC circuits use a
catch diode such as 1N4148, shown on previous page.
Protect the sensor from excessive electrical spikes by isolating the power, whenever
possible.
The sensor materials must be Chemically compatible with the liquids to be measured.
Design a fail-safe system for possible sensor and/or power failure.
Never use the sensor in environments classified as Hazardous.
