Analog Input - FlowLine Commander LI90 Series Quick Start Manual

BASIC CONFIGURATION DATA
There are several configuration aspects similar for all the Commander Controller's applications.

ANALOG INPUT

The Commander accepts any 4-20 mA signal. This signal may be scaled to the size of the tank or vessel or
with a non-configured transmitter (in its original factory setup). If the transmitter has been scaled or configured
to the size of the tank, use the Scaled Input for configuration. If the transmitter is a fixed output or in its original
factory settings, then use the Non-Scaled Input for configuration. Analog data can be configured for scaled
and non-scaled output, as follows:
Scaled Inputs
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, the data is
displayed as follows:

Sensor Max. Range – Displays the distance from the bottom of
the tank to the bottom of the installed sensor.

Sensor Dead Band – Displays the distance from the full level of
liquid to the bottom of the sensor.

Sensor Height – Displays 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 – Displays 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 – Displays the display value when the tank is
empty.

Full Setting – Displays the display value when the tank is full.
Non-Scaled Inputs
When using a transmitter that is either set with its original Factory
Settings or with a transmitter that has a fixed (non-configurable) 4-
20 mA output, the data is displayed as follows:

Sensor Max. Range – Displays the maximum range of the
sensor. This is typically the 4 mA set point for the sensor. Use
the sensor's manual to obtain the sensors maximum range (4
mA output).

Sensor Dead Band – Displays the dead band for the level
sensor. Use the sensor's manual to obtain the sensors dead
band (20 mA output).

Sensor Height – Displays the distance from the bottom of the
tank to the bottom of the installed sensor

Sensor Fill-H – Displays the distance from the bottom of the
tank to the highest level of liquid

Empty Setting – Displays the empty tank value.

Full Setting – Displays the full tank value.
