Three Phase Duplex
SJE-Rhombus® Type 322
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.
Most Type 322 panels are designed to operate with three or four fl oat sys-
tems. The three fl oat system is standard, performing the common pump
stop, lead pump start, and lag pump start/high level alarm functions. The
four fl oat system utilizes separate fl oats for each function.
NOTE: Options ordered may affect the number of fl oats and their
functions. Please reference the schematic provided with the control
panel for proper installation.
Installation of Floats
CAUTION: If control switch cables are not wired and mounted in the correct
order, the pump system will not function properly.
WARNING: Turn off all power before installing fl oats in pump chamber.
Failure to do so could result in serious or fatal electrical shock.
1. Use fl oat label kit to identify and label cables on both fl oat and stripped
ends (stop, lead, lag, alarm, etc.). See schematic for fl oat options.
2. Determine your normal operating level, as illustrated in Figures 1 & 2.
3. Mount fl oat switches at appropriate levels as illustrated in Figures 3-5.
Be sure that fl oats have free range of motion without touching each
other or other equipment in the basin.
If using the mounting clamp; follow steps 4-6.
4. Place the cord into the clamp as shown in Figure 5.
5. Locate the clamp at the desired activation level and secure the clamp
to the discharge pipe as shown in Figure 5.
NOTE: Do not install cord under hose clamp.
6. Tighten the hose clamp using a screwdriver. Over tightening may result
in damage to the plastic clamp. Make sure the fl oat cable is not allowed
to touch the excess hose clamp band during operation.
NOTE: All hose clamp components are made of 18-8 stainless steel
material. See your SJE-Rhombus® supplier for replacements.

Installation
Mounting the Control Panel
1. Determine mounting location for panel. If distance
exceeds the length of either the fl oat switch cables or
the pump power cables, splicing will be required. 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.
NOTE: Be sure the incoming power, voltage, amperage,
and phase meet the requirements of the pump motors
being installed. If in doubt, see the pump identifi cation
plate for electrical 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 and switch cables through.
5. Attach cable connectors and/or conduit connectors to
control panel.
FOR INSTALLATION WITHOUT A SPLICE,
GO TO STEP 10; FOR INSTALLATION REQUIRING
A SPLICE, FOLLOW STEPS 6-9.
6. Determine location for mounting junction box according
to state and local code requirements. Mount the junction
box to proper support.
Installation Instructions
7. Run conduit to junction box. Drill proper size holes for
the type of conduit used. Attach connectors to junction
box.
8. Identify and label each wire before pulling through con-
duit into control panel and junction box. Make wire splice
connections at junction box.
9. Firmly tighten all fi ttings on junction box.
10. If a junction box is not required, pull cables through
conduit into control panel.
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. Connect pump wires directly to the motor contactors
terminal positions T1, T2, and T3.
NOTE: Three-phase motors will run in either direction.
Check pump motor before installation for proper rotation.
To correct rotation, change pump cable connections on
any two terminals T1-T2-T3.
13. Connect “power-in” conductors to proper locations:
208/240/480 VAC on the 3 position terminal block. In-
stall tagged factory wire to appropriate transformer
primary voltage tap.

Operations
SJE-Rhombus® Type 322 panels are designed to
operate with three or four fl oats for pump sequencing. The
standard fl oat functions are common pump stop, lead pump
start, lag pump start/alarm (three fl oats), or separate lag
and alarm fl oats (four fl oats). Other fl oat options, such as
redundant off, are available.
Three Float Operation: As the liquid level passes the
stop fl oat and tips it to the ON (closed) position, the panel
will remain inactive. As the liquid level tips the lead fl oat,
the lead pump will start. If the liquid level tips the lag/alarm
fl oat, the lag pump will start and the audio/visual alarm will
activate. Both pumps and the alarm will remain active until
the liquid level drops and the lag fl oat is in the OFF (open)
position. At this time the alarm will silence. Both pumps will
remain on until the liquid level drops to normal and all three
fl oats are in the OFF (open) position. When both pumps have
stopped running, the alternator will switch the lead pump and
lag pump operating functions in the next sequence.
Four Float Operation: The alarm will activate and
remain on only if the alarm fl oat is tipped to the ON (closed)
position.
Alarm System (Horn and Indicator)
When an alarm condition occurs, a red light and a horn will
be activated. If the test/normal/silence switch is moved to the
silence position, the horn will be silenced. When the alarm
condition is cleared, the alarm system is reset. The alarm
system can be tested by moving the test/normal/silence
switch to the test position.
Control/Alarm Switch
Allows the control/alarm power to be turned on or off.
HOA Switch
A hand-off-automatic switch is provided for each pump. In
the hand mode, the pump will turn on unless other safety
features are employed. In the automatic mode, the pump will
turn on from commands by the fl oat switches.
Motor Protective Switch
A motor protective switch is supplied for each pump to pro-
vide an adjustable overload, branch circuit protection and
disconnect. The overload must be set in the fi eld. To set the
overload, dial the amp scale to the pump’s full load amp rat-
ing (FLA). If the FLA’s are unknown, use a calibrated amp
meter to measure the pump amperage draw under loaded
conditions. An auxiliary contact is wired in series with the
magnetic contactor coil so that on an overload trip, the mag-
netic contactor will be disabled. In the event of an overload
trip, the motor protective switch must be reset by fi rst turning
the selector handle counterclockwise to the OFF position and
then turning the handle 90o clockwise to the ON position.
Control/Alarm Light
The light will illuminate when the control ON/OFF switch is
in the ON position.
Pump Run Lights
Each pump has a run light. The run light will be ON in either
the hand or the automatic mode when the pump is called
to run.
Float Status Lights
Lights will illuminate when the respective fl oat is in the closed
position.
Dry Auxiliary Contacts (optional)
Normally open - Contacts are open under normal conditions
and closed when alarm condition is present.
Normally closed - Contacts are closed under normal condi-
tions and open when alarm condition is present.
Both types automatically reset once alarm condition is
cleared.
Seal Failure Circuit and
Indicator Light (optional)
The seal fail circuit has resistance sensitivity and will sense
the presence of water in the pump seal chamber. Upon in-
stallation, turn the sensitivity dial on the seal fail module to
the point where the light turns on, then dial back slowly until
the light turns off. If water enters the seal chamber at this
point, the seal fail circuit will sense the change in resistance.
After a short time delay, the indicator light will turn on. When
the condition is cleared, the relay will de-energize and the
indicator light will turn off. The seal fail relay has a sensitivity
adjustment so that false readings may be tuned out.
Thermal Cutout (optional)
The thermal cutout is wired in series with the magnetic
contactor coil. If the pump’s thermal switch opens on high
temperature, the contactor will turn off and stop the pump.
When the thermal switch cools and closes, the magnetic
contactor will turn on if the pump is called to run.

Warranty void if panel is modifi ed.
Alarm Horn
Pressing the alarm test/normal/silence switch to the test position
or activating the alarm fl oat should turn on the alarm horn. If the
horn does not sound, replace with horn of same type.
Alarm Light
Pressing the alarm test/normal/silence switch to the test position or
activating the alarm fl oat should turn on the alarm light. If the light
does not activate, replace with bulb of same type.
Alternating Relay or Device
The alternation can be sequenced by lifting the fl oat switches or
making jumper wires to simulate the fl oats closing. If the alterna-
tor fails during testing, replace with same type. Consult factory at
1-800-RHOMBUS (1-800-746-6287) when in doubt about testing
procedures or results.
Float Controls
Check the fl oats through their entire range of operation. Clean,
adjust, or replace damaged fl oats.
Checking the fl oat resistance - The fl oat resistance can be mea-
sured to determine if the fl oat is operating correctly or is defective.
Use the following procedure to measure the fl oat resistance:
Troubleshooting
1. Isolate the fl oat by disconnecting one or both of the fl oat leads
from the fl oat terminals.
2. Place one ohmmeter lead on one of the fl oat wires, and the
other ohmmeter lead on the other fl oat wire.
3. Place the ohmmeter dial to read ohms and place on the R X
1 scale. With the fl oat in the “off” position, the scale should
read infi nity (high resistance). Replace the fl oat if you do not
get this reading. With the fl oat in the ON position, the scale
should read nearly zero (very low resistance). Replace the
fl oat if you do not get this reading.
NOTE: Readings may vary depending on the length of wire and
accuracy of the measuring device.
Fuses
Check the continuity of the fuse. Pull the fuse out of the fuse block.
With the ohmmeter on the R X 1 scale, measure resistance. A
reading of infi nity indicates a blown fuse and must be replaced.
Replace fuse with same type, voltage and amp rating.
Magnetic Contactor
Contacts - Check the contacts for severely burnt or welded con-
tacts. The contactor arm should move freely.
Coil - Measure the coil by disconnecting one of the coil leads.
Measure the coil resistance by setting the ohmmeter on the R X
1 scale. A defective coil will read zero or infi nity, indicating a short
or opened coil respectively. If contactor is defective, replace with
same type.
NOTE: Readings may vary slightly depending on the and accuracy
of the measuring device.
Motor Protective Switch
Test by inserting a paper clip or other small device into the test
hole and push to the left. The relay should trip.
