Fuses
Check the continuity of the fuse. With power OFF,
pull the fuse out of the fuse block. With the ohm-
meter on the R X 1 scale, measure resistance. A
reading of innity indicates a blown fuse and must
be replaced. Replace fuse with same type, voltage
and amp rating.
Indicator Lights
If defective, replace all indicator pilot lights with
same type.
Magnetic Contactor
Contacts - Check the contacts for severely burnt
or welded contacts. The contactor arm should
move freely.
Coil - Measure the coil by disconnecting one of
the coil leads. Measure the coil resistance by set-
ting the ohmmeter on the R X 1 scale. A defective
coil will read zero or innity, indicating a short or
opened coil respectively. Replace defective con-
tactor with same type.
NOTE: Readings may vary depending on 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.
Alarm Horn
Moving the alarm test/normal/silence switch to the
test position or activating the alarm oat should
turn on the alarm horn. If the horn does not sound
replace with horn of same type.
Alarm Light
Moving the alarm test/normal/silence switch to the
test position or activating the alarm oat should
turn on the alarm light. If the light does not activate,
replace with bulb of same type.
Float Controls
Check the oats during their entire range of opera-
tion. Clean, adjust, or replace oats.
Checking the oat resistance - The oat resis-
tance can be measured to determine if the oat
is operating correctly or is defective. Use the fol-
lowing procedure to measure the oat resistance:
1. Isolate the oat by disconnecting one or both
of the oat leads from the oat terminals.
2. Place one ohmmeter lead on one of the oat
wires, and the other ohmmeter lead on the
other oat wire.
3. Place the ohmmeter dial to read ohms and
place on the R X 1 scale. With the oat in the
“off” position, the scale should read innity
(high resistance). Replace the oat if you do
not get this reading. With the oat in the ON
position, the scale should read nearly zero
(very low resistance). Replace the oat if you
do not get this reading.
NOTE: Readings may vary depending on the
length of wire and accuracy of the measuring
device.
Troubleshooting
Installation of Floats
Standard three phase simplex panels are designed
to operate with three oats. These oats operate the
pump stop, pump start, and high level alarm functions.
NOTE: Options ordered may affect the number
of oats and their functions. Please reference
the schematic provided with the control panel for
proper installation.
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 oats in
pump chamber. Failure to do so could result in serious
or fatal electrical shock.
1. Use oat label kit to identify and label cables on
both the oat and stripped ends (stop, start, alarm,
etc.). See schematic for oat options.
2. Determine your normal operating level, as illustrated
in Figure 1.
3. Mount oat switches at appropriate levels as il-
lustrated in Figures 2-4. Be sure that 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
2.
5. Locate the clamp at the desired activation level and
secure the clamp to the discharge pipe as shown
in Figure 2.
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 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.

Mounting the Control Panel
1. Determine mounting location for panel. If
distance exceeds the length of either the oat
switch cables or the pump power cables,
splicing will be required. For outdoor or wet
installation, we recommend the use of a 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 motor being installed. If in doubt,
see the pump identi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 junction box to proper support.
7. Run conduit to junction box. Drill proper size
holes for the type of conduit used. Attach
connectors to junction box.
Installation Instructions
8. Identify and label each wire before pulling
through conduit into control panel and junction
box. Make wire splice connections at junction
box.
9. Firmly tighten all ttings on junction box.
10.If a junction box is not required, pull cables
through conduit into control panel.
11. Set motor protective switch:
a) set the dial 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
contactor 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 on 3 position terminal
block. Install tagged factory wire to
appropriate transformer primary voltage
tap.
VERIFY CORRECT OPERATION OF
CONTROL PANEL AFTER
INSTALLATION IS COMPLETE.
Operations
Three phase simplex control panels are designed
to operate in a three oat system as standard.
When all oats are in the open or OFF position,
the panel is inactive. As the liquid level changes
and closes the stop oat, the panel remains inac-
tive until the start oat also closes. At this point
the pump will start, assuming the HOA switch is in
the AUTOMATIC mode and the power is ON. The
pump will remain ON until both the stop and start
oats open (return to the OFF position). If the liquid
level travels beyond both the stop and start oats
and reaches the alarm oat, the audio/visual alarm
will be activated. The alarm horn can be silenced
by pressing the silence switch.
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.
HOA Switch
A hand-off-automatic switch is provided for the
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 com-
mands by the oat switches.
Motor Protective Switch
A motor protective switch is supplied for the pump
to provide an adjustable overload, branch circuit
protection and disconnect. The overload must be
set in the eld. To set the overload, dial the amp
scale to the pump’s full load amps (FLA). If the
FLA’s are unknown, use a calibrated amp me-
ter 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 magnetic contactor will be
disabled. In the event of an overload trip, the mo-
tor protective switch must be reset by rst turning
the handle counterclockwise to the OFF position
and then turning the handle 90oclockwise to the
ON position.
Pump Run Light
The run light will be ON in either the hand or the
automatic mode when the pump is called to run.
Control Power Light
Light will illuminate when the control circuit has
power.
Alarm Power Light
Light will illuminate when the alarm circuit has
power.
Alarm Fuse
Provides alarm circuit protection and provides a
means of disconnecting alarm circuit power.
Control Fuse
Provides control circuit protection and provides a
means of disconnecting control circuit power.
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 conditions and open when alarm condition
is present.
Both types automatically reset once alarm condi-
tion 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 installation, 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 chamber circuit will sense a 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 circuit is wired in series with
the magnetic contactor coil. If the pump’s thermal
switch opens on high temperature, the magnetic
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.
NOTE: Some options ordered may not be included
in this manual.
