Installation Instructions and Operation/Troubleshooting Manual
This control panel must be installed and serviced by a
licensed electrician in accordance with the National Electric Code
NFP A-70, state and local electrical codes. All conduit running from
the sump or tank to the control panel must be sealed with conduit
sealant to prevent moisture or gases from entering the panel. NEMA 4X enclosures are for indoor or outdoor use, primarily to provide
a degree of protection against corrosion, windblown dust and rain,
splashing water and hose-directed water. Cable connectors must be
liquid-tight in NEMA 4X enclosures.
The Level Sensor is suitable for use in sewage applications.
Do NOT use in potable water.
Installation
Intelligent Panel Series control panels are designed to control pump(s).
The controller records pump status, number of cycles, elapsed run
time, alarm counts, and signal error counts.
Mounting the Control Panel
Note: The control panel should not be mounted in a location that may
be subject to submersion.
1. Determine mounting location for panel. If distance exceeds the
length of either the sensor or fl oat cables or the pump power
cables, splicing will be required. Note: For splicing Level Sensor
cord, use only shielded cable. Splice conductors as well as
shielding. Maximum total cable length is 100 feet. For outdoor
or wet installation, we recommend the use of an SJE-Rhombus
liquid-tight junction box with liquid-tight connectors to make required
connections. You must use conduit sealant to prevent moisture
or gases from entering the panel.
2. Mount control panel with mounting devices furnished.
3. Determine conduit entrance locations on control panel. Check local
codes and schematic for the number of power circuits required.
(Level Sensor cable requires separate conduit from power
and pump cables.)
Note: Be sure the proper power supply voltage, amperage, and phase
meet the requirements of the pump motor(s) being installed. If in doubt,
see the pump identifi cation plate for voltage/phase requirements.
4. Drill proper size holes for type of connectors being used.
Note: If using conduit, be sure that it is of adequate size to pull the
pump cable(s) through.
5. Attach cable connectors and/or conduit connectors to control panel.
FOR INST ALLATION REQUIRING A SPLICE, FOLLOW STEPS 6-10;
FOR INST ALLATION WITHOUT A SPLICE, GO TO STEP 11.
6. Determine location for mounting junction box according to local
code requirements. Do not mount the junction box inside the
sump or basin.

Installation Instructions
7. Mount junction box to proper support.
8. Run conduit to junction box. Drill proper size holes for the type of conduit used.
9. Identify and label each wire before pulling through conduit into control panel and junction box. Make wire
splice connections at junction box.
10. Firmly tighten all fi ttings on junction box.
11. Set motor protective switches:
a) set the dials to match motor full load amps.
b) turn dial on motor protective switch to the ON position.
NOTE: Resetting the dial with power applied to the motor protective switch could start the motor.
12. If a junction box is not required, pull cables through conduit into control panel.
13. Connect pump wires per wiring diagram or schematic, and sensor or fl oat wires to the proper terminals as
shown on the schematic.
14. Connect pump, control, and alarm incoming power conductors to proper position on terminals. See schematic
for terminal connections.
VERIFY CORRECT OPERATION OF CONTROL PANEL AFTER INSTALLATION IS COMPLETE.
Installation of Level Sensor and Floats
CAUTION: If control switch cables are not wired and mounted in the correct order, the pump system will not
function properly. Sensor and fl oat cables need to run in separate conduit from pump and power lines.
WARNING: Turn off all power before installing pump wires in pump chamber. Failure to do so could result in
serious or fatal electrical shock.
NOTE: The Level Sensor operates between 0 and 39.9 inches of water pressure. The Level Sensor reads 0 inches
at the approximate point shown in Figure 2. As the liquid level rises, the IFS display shows depth of liquid from the
zero point. The minimum set point for the stop or redundant off level is 3 inches (measured from 0) see Figure 2.
The maximum set point allowed is 39.9 inches (measured from 0). Operating temperature range is 32ºF (0ºC)
to 120ºF (50ºC).
1. Determine the nominal operating levels for the confi guration, as illustrated in Figure 3 or 4.
2. Position Level Sensor at appropriate location on pipe and secure sensor and vent as shown in Figure 2 using
hose clamps.
WARNING: Do not support the Level sensor by the cable. Position the sensor in the tank so that nothing is
pushing in the diaphragm.
3. Position vent so it is above the water level and stow excess vent tube as shown in Figure 2.
WARNING: Do NOT kink or place black tubing under hose clamp. Doing so will cause sensor to fail.
4. If optional high water or redundant off fl oats are used, position and secure as shown in Figures 1, 3 or 4.
Redundant off fl oat should be located to activate at approximately the zero point for the Level Sensor per
Figure 3 or 4.
NOTE: Liberty Pumps, Inc. recommends using the optional high water alarm fl oat for added protection against
fl ooding.
5. Tighten all hose clamps using a screw driver. Over tightening may result in damage to the plastic parts.
NOTE: All hose clamp components are made of 18-8 stainless steel material. See your Liberty Pumps, Inc.
supplier for replacement parts.
6. Functionally test the system by fi lling the tank and witnessing proper operation.

Operations
The Intelligent Panel Series control panel uses the Level Sensor to continuously monitor and control the liquid
level in the tank. An optional high water alarm fl oat and redundant off fl oat can be used to provide additional
protection from high or low water conditions.
Hand Operation - The level must be above the stop/redundant off set point to put the panel in HAND operation.
To override the stop/redundant off set point, press and hold the HAND button. The pump runs until the HAND
button is released. The panel then returns to the AUTO mode. If the level is above the stop/redundant off set point
and the panel is placed in the HAND mode, and left in HAND mode, the pump continues to run until the liquid
level reaches the stop/redundant off set point. The panel then returns to the AUTO mode.
Off Operation - The panel is in the OFF mode.
Auto Operation - In time dose (t-dose) mode, when the panel is in the AUTO mode, the timer controls pump
ON and OFF time as long as the redundant off and timer enable set points are activated. In demand (d-dose),
the stop and lead set points control the pump.
Level Indicators- Illuminate if the corresponding set point is triggered.
Green Control and Alarm Power Indicators - (mounted on interior circuit board) Illuminates when
control power and alarm power is present. If the control fuse needs replacing the panel sounds an alarm.
LED Display- Used to view and set panel settings and cycle count data. Will turn off after fi ve minutes of non-use.

Troubleshooting
Level Sensor
1. Verify that the black tube is not kinked or has any
holes in it. If either condition exists, the pressure
sensor may fail or give inaccurate level readings.
2. Vent must be above water and unobstructed.
This is required to compensate for barometric
pressure changes. Obstructing the vent will result
in inaccurate level readings.
3. The black diaphram is located on the end of the
sensor body . The diaphragm must not be damaged
or deformed. A damaged or deformed diaphragm
will result in inaccurate level readings.
4. Verify the bottom of the Level Sensor is not resting
on the bottom of the tank or on any other obstacle.
5. Verify that the electrical cable is not damaged or
severed.
6. Verify that the shielding for cable is properly
attached to ground.
7. If the panel includes the optional redundant off fl oat,
verify that the fl oat is properly wired to the panel.
Fuse
To check the continuity of the fuse, pull the fuse out of
the fuse holder. With the ohmmeter on the R X 1 scale,
measure resistance. A reading of infi nity (high resistance)
indicates a blown fuse that must be replaced with a fuse
of the same type, voltage, and amp rating.
Alarm Light
With power on, hold the test/normal/silence switch in
the “test” position. The alarm light should turn on. If not,
replace the light with that of the same type.
Alarm Horn
With power on, hold the test/normal/silence switch in
the “test” position. The alarm horn should turn on. If not,
replace the horn with that of the same type.
