WE DO YOUR LEVEL BEST
Thank you for purchasing the Commander Controller (LI90). The LI90 Series is a general purpose level
controller displaying engineering units for up to four 4-20 mA continuous level sensor receivers and 6
programmable relays.
UNPACKING THE COMMANDER CONTROLLER
When unpacking the Loop-Powered Meter, thoroughly inspect the unit for
any damage that may have occurred during shipping. Be sure to report any
damage, as well as any missing parts or malfunctions to your supplier or
Flowline.
ABOUT THE COMMANDER CONTROLLER
Before using the Commander Controller, here is some general information
to help keep the unit at peak performance.
Temperature / Ventilation
The Commander Controller’s layout design allows for adequate ventilation
when used properly and maintained within an ambient temperature range
of between 0°C and +50°C. Consider ventilation and temperature
limitations when operating at the extreme ends of the ambient temperature
range. Should a cooling device be required, for example, allow adequate
clearance for ventilation.
Front View
Side View
Orientation
When panel-mounted, there are no orientation restrictions on the Commander Controller.
Noise
Consider the impact on ventilation, temperatures and performance if noise suppression devices are needed.
Be sure to maintain an adequate distance between the controller and noisy devices such as relays, motor
starters, etc.
Shock and Vibration
The Commander Controller has been designed to operate in typical industrial
environments that may inflict some shock and vibration on the unit. For
applications that may inflict excessive shock and vibration, please use proper
dampening techniques or relocate the Commander to a location that minimizes
shock and/or vibration.
Configuration
The Commander Controller is configured through the Human Machine Interface
(HMI) located on the front cover.
Front Cover

QS301036 Rev A1 3 |
MOUNTING THE COMMANDER CONTROLLER
The Commander Controller can be mounted through a panel or on a DIN rail.
Panel Mounting
Panel design should be completed with the Commander
Controller’s requirements in mind. Use the standard cutout for a
¼ DIN: 3.622” (92 mm) x 3.622” (92 mm). Use the four mounting
clips to secure the display to the panel. A mounting clip will
attach to all four sides of the display. With this in mind, panel
mount accordingly:
1) Remove all connectors from the Commander Controller;
2) Press the DIN rail clip up for passing the Commander
Controller through the cutout;
3) Verify that the Commander Controller’s gasket is
installed, is free from dust and debris, and has all corners
secure;
4) Pass the Commander Controller through the cutout; Panel Mounting Cut Out
5) Insert each of the four mounting clips into the Commander Controller’s case. One clip should be
installed at each corner. Tighten each screw so that the clip is held in place;
6) Tighten the screws on the clips so that the gasket is pressed against the panel; and
7) Mounting is now complete.
DIN rail mounting
The Commander Controller is designed to clip onto a standard 35
millimeter DIN rail. If your installation requires liquid or dust
protection, make sure the controller is placed in an appropriate
sealed panel when mounting on the DIN rail. Use the following
steps to mount on the DIN rail.
1) Move the DIN rail clip to the lower position;
2) Clip the “Top Clips” on the top of the DIN rail;
3) Press the Commander Controller into place; and
4) Press the DIN rail clip up. A small flat-head screwdriver
can be used in the slot of the DIN rail clip if clearance is an
issue. Din Rail Mounting
The DIN rail connection does NOT provide an earth ground.
Only qualified personnel familiar with the construction and operation of this equipment and the hazards involved
should install, adjust, operate, or service this equipment. Read and understand all applicable manuals in their
entirety before proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life. All
applicable codes and standards need to be followed in the installation of this product.

|4 QS301036 Rev A1
GROUNDING THE COMMANDER CONTROLLER
Ideally, a ground resistance measurement from equipment to earth is 0 ohms. This may actually turn out to be
a bit higher. While the U.S. National Electrical Code (NEC) states the resistance to ground shall not exceed 25
ohms, resistance to ground when using the Commander Controller should not exceed 15 ohms from
Commander Controller to ground. Resistance greater than 25 ohms can impede performance and possibly
damage the Commander Controller.
Testing for a Good Ground
In order to test ground resistance, a Ground Resistance Tester must be used. A typical Ground Resistance
Meter Kit contains a meter, two or three wire leads, and two ground rods. Instructions are supplied for either a
two-point or three-point ground test. The diagram below shows a two-point ground connection test.
Ground Connection Test Diagram
To avoid the risk of electric shock or burns, always connect the
safety (or earth) ground before making any other connections.

QS301036 Rev A1 5 |
CONNECTIONS TO THE COMMANDER CONTROLLER
Power Connections
The Commander Controller has one grounding connection and power connections for 10-30 VDC. The
configuration of the LI90 series is retained if there is a power loss or power is turned off.
Receiving Connections (Transmitter/Sensor Inputs)
The Commander Controller can receive signals from up to four 4-20 mA sensors. The 24VDC power supply
may be shared with the Power terminal as well as the other transmitters.
Power Connections Receiving Connections (Transmitter/Sensor Inputs)
Transmitting Connections (Relay Outputs)
The Commander Controller can control up to six relays, depending on the application selection. These relays
can switch voltages up to 275 VAC, 30 VDC with a maximum output current of 3 A at 250 VAC, resistive. All
relays are Normally Open (NO) relays and may share the same power source.
Relay wiring example Relay Output Connections

|6 QS301036 Rev A1
Observe all safety regulations. Electrical wiring should be performed in accordance with all agency
requirements and applicable national, state, and local codes to prevent damage to the meter and ensure
personnel safety.
Be sure to fuse the voltage measurement wires, locating them as close to the source as possible, to reduce
the risk of fire, electrical shock, or physical injury.
Fuses should be replaced with the same type and rating to protect against fire and shock hazards. Repeated
fuse failure, indicates a defective condition that will not clear by replacing the fuse.
SOME ADDITIONAL NOTES ON SAFETY:
When connecting electric circuits or pulse-initiating equipment, open their related breakers. Do not
make connections to live power lines.
Make connections to the module first; then connect the circuit to be monitored.
Route power wires in a safe manner in accordance with good practice and local codes.
Wear proper personal protective equipment including safety glasses and insulated gloves when making
connections to power circuits.
Ensure hands, shoes, and floors are dry before making any connection to a power line.
Make sure the unit is turned OFF before making connection to terminals. Make sure all circuits are de-
energized before making connections.
Before each use, inspect all cables for breaks or cracks in the insulation. Replace immediately if
defective.

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.
Scaled Output Data
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.

the two levels reaches a specific differential. The relays will de-activate (de-energize) when the differential
becomes less than the OFF value. As a result, Relays #3 and #4 will have a Differential ON and Differential
OFF setting instead of the Relay ON and Relay OFF settings.
Differential greater that 35”, Relay #3 will
energize Differential less that 10”, Relay #3 will de-energize
EXAMPLE: Relay #3 will energize when the difference between Level #1 and Level #2 is greater than 35”.
Relay #3 will de-energize when the difference between Level #1 and Level #2 is less than 10”. Level #1 is the
upstream level used for main differential control while Level #2 is the downstream level.
1. Press ENTER key for 5 seconds to access the Config Inputs and Config Outputs screen.
2. Press the Config Outputs Soft Key to begin. The first screen to appear is for Relay #1.
a. Use the Next Soft Key to advance to the next relay.
b. Use the Back Soft Key to return to the previous screen.
3. If the correct Relay is displayed, press the Config Relay #_ Soft Key to advance to Relay #_ ON /
Differential #_ ON.
4. Relay #_ ON / Differential #_ ON is the set point where the relay will
energize. For Alarm functions, this is the liquid level where the alarm
will activate. For Automatic Fill or Empty functions, this is the level
where the process begins.
a. If a tank’s sensor is reading between 0 to 500 gallons, then the relay set points must be
measured in gallons.
5. To change the Relay #_ ON / Differential #_ ON value, first press the ENTER key. The value will now
be highlighted and you can enter the
number using the F-Keys as you would a 10-digit key pad, with the down
arrow to enter the decimal point. Then, press ENTER again to complete
the entry and store the value into memory.
6. Press the Next Soft Key to proceed to Relay #_ OFF / Differential #_ OFF.
