SJE Rhombus® Type IFS w/C-Level™ Sensor
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 NFPA-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 C-Level sensor is suitable for use in sewage applications.
Do NOT use in potable water.
Installation
Installer Friendly Series® (IFS) control panels are designed to control
pump(s). The controller records number of pump cycles, elapsed run
time, alarm counts, and signal error counts.
Warranty void if panel is modied.

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 oat cables or the pump power
cables, splicing will be required. Note: For splicing C-Level cord,
use only shielded cable. Splice conductors as well as shielding.
Maximum total cable length is 300 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. (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 identication plate for voltage/phase requirements.

Installation Instructions
6. Determine location for mounting junction box according to local code requirements. Do not mount the
junction box inside the sump or basin.
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 ttings on junction box.
11. If a junction box is not required, pull cables through conduit into control panel.
12. Connect pump wires per wiring diagram or schematic, and sensor or oat wires to the proper terminals as
shown on the schematic.
13. 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 C-Level Sensor and Floats
WARNING : Verify C-Level™ and IFS panel are matched with CL40 or CL100. Using wrong sensor with panel will
cause settings to be incorrect.
CAUTION: If control switch cables are not wired and mounted in the correct order, the pump system will not function
properly. Sensor and oat cables need to run in separate conduit from pump and power lines.
Industry practices suggest that a secondary device, such as a oat switch, be used for redundant
activation of the high level alarm and pump shut o.
WARNING: Turn o all power before installing pump wires in pump chamber. Failure to do so could result in serious
or fatal electrical shock.
NOTE: The C-Level™ sensor operates between 0 and 39.9 inches of water pressure for the CL40 or between 0 and
99.9 inches of water pressure for the CL100. The C-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 (demand) or redundant o (timed dose) level is 4 inches (measured from 0) see Figure 2.
The maximum set point allowed is 39 inches (measured from 0) for the CL40 or 99 inches (measured from 0) for the
CL100. Operating temperature range is 32ºF (0ºC) to 120ºF (50ºC).
1. Determine the nominal operating levels for the conguration, as illustrated in Figure 3 or 4.
2. Position C-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 C-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 o oats are used, position and secure as shown in Figures 1, 3 or 4.
Redundant o oat should be located to activate at approximately the zero point for the C-Level per Figure
3 or 4.
NOTE: SJE Rhombus® recommends using the optional high water alarm oat for added protection against
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 SJE Rhombus® supplier
for replacement parts.
6. Functionally test the system by lling the tank and witnessing proper operation.

Operations
The Installer Friendly Series (IFS) control panel uses the C-Level sensor to continuously monitor and control
the liquid level in the tank. An optional high water alarm oat and redundant o oat can be used to provide
additional protection from high or low water conditions.
Hand Operation - The level must be above the stop/redundant o set point to put the panel in HAND operation.
To override the stop/redundant o 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 o 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 o 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 o 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 o after ve minutes of
non-use.

Troubleshooting
C-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 C-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 o oat, verify that the 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 innity (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.
