Rev 1_3 Commander LI90 Series

Common Information – There are several configuration aspects that are similar for all three

applications in the LI90 series.

• Analog Input

o The Commander accepts any 4-20 mA signal.

o The Commander has the ability to accept a 4-20 mA that has been scaled to the

size of the tank / vessel or with a 4-20 mA that is from a non-configured

transmitter (in its original factory setup).

o There are six parameters required to configure an analog input in the LI90 series.

o For a scaled output. Use this description when using a transmitter that has been

configured with 4 mA set to an empty tank/vessel and 20 mA set to a full

tank/vessel.

• Sensor Max. Range – This is the distance from the bottom of the tank to

the bottom of the installed sensor.

• Sensor Dead Band – This is the distance from the full level of liquid to

the bottom of the sensor.

• Sensor Height – This is the distance from the bottom of the tank to the

bottom of the installed sensor. This will be the same setting as the Sensor

Max. Range.

• Sensor Fill_H – This is the distance from the bottom of the tank to the

highest level of liquid. Adding the Fill_H value to the Dead Band value

will equal the Max. Range or Height values.

• Empty Setting – This is the display value when the tank is empty.

• Full Setting – This is the display value when the tank is full.
