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 1 enclosures are for indoor use only, primarily to

provide a degree of protection against contact with enclosed equipment.

Cable connectors are not required to be liquid-tight in NEMA 1 enclosures.

Do not use NEMA 1 enclosures if subjected to rain, splashing water

or hose-directed water. NEMA 4X enclosures are for indoor or out-

door 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.

A standard Type 112 panel is designed to operate with three ﬂ oats. These

ﬂ oats operate pump stop, pump start, and high level alarm functions.

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 label ﬂ oats for speciﬁ c operation (stop, start,

alarm, etc.). See schematic for ﬂ oat options.

2. Determine your normal operating level, as illustrated in Figure 1.

3. Mount ﬂ oat switches at appropriate levels as illustrated in Figures

2-4. 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 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 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.

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 (mounting ﬂ anges are furnished

with control panel).

3. Determine conduit entrance locations on control

panel. Check local codes and schematic for the

number of power circuits required.

NOTE: Be sure the proper power supply voltage,

and phase are the same as the pump motor 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.

You must use conduit sealant to prevent mois-

ture or gases from entering the panel.

5. Attach cable connectors and/or conduit connectors

to control panel.

FOR INSTALLATION WITHOUT A SPLICE,

GO TO STEP 11;

FOR INSTALLATION REQUIRING

A SPLICE, FOLLOW STEPS 6-10.

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. Attach liquid-tight con-

nectors to junction box.

9. Identify and label each wire before pulling through

conduit into control panel and junction box. Pull

pump power cables and control switch cables

through connectors into junction box. Make wire

splice connections at junction box.

10. Firmly tighten all ﬁ ttings on junction box. Insure all

cable connectors are liquid-tight and sealed.

11. If a junction box is not required, identify and label

cables on both ﬂ oat and stripped ends.

12. Connect pump and ﬂ oat wires to proper position

on terminals. See schematic inside control panel

for terminal layouts.

13. Connect control, alarm and pump power conduc-

tors to proper position on terminals. See schematic

inside control panel for terminal connections.

NOTE: It is the recommendation of the factory to use

separate pump and control/alarm power sources.

VERIFY CORRECT OPERATION OF CONTRO

PANEL AFTER INSTALLATION IS COMPLETE.

Alarm System (Horn and Indicator)

When an alarm condition occurs, a red light and 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 commands by the ﬂ oat

switches.

Pump Run Light

The run light will be ON in either the hand or the auto-

matic mode when the pump is called to run.

Circuit Breaker (optional)

The pump circuit has a thermal-magnetic circuit breaker

which provides pump disconnect and branch circuit

protection.

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 condition is

cleared.

NOTE: Some options ordered may not be included

in this manual.

Float with cable weight

SJE-Rhombus® Type 112 control panels are designed

to operate in a three ﬂ oat system as standard. When

all ﬂ oats are in the open or OFF position, the panel is

inactive. As the liquid level changes and closes the

stop ﬂ oat, the panel remains inactive until the start ﬂ oat

also closes. At this point the pump will start, providing

the HOA switch is in the AUTOMATIC mode and the

power is ON. The pump will remain ON until both the

stop and start ﬂ oats open (return to the OFF position).

If the liquid level travels beyond both the stop and start

ﬂ oats and reaches the alarm ﬂ oat, the alarm will be

activated. The alarm horn can be silenced by moving

the test/normal/silence switch to the silence position.

Operations

Checking the ﬂ oat resistance - The ﬂ oat resistance can be

measured to determine if the ﬂ oat is operating correctly or is defec-

tive. Use the following procedure to measure the ﬂ oat resistance.

WARNING: Disconnect incoming power to panel.

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. With power OFF, 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 Coil

WARNING: Disconnect incoming power to panel.

Check 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. Replace defective contactor with same type.

NOTE: Readings may vary depending on the accuracy of the

measuring device.

Alarm Horn

Moving the test/normal/

silence switch to the test

position or activating the

alarm float should turn

on the alarm horn. If the

horn does not sound,

replace horn with same type.

Alarm Light

Moving the test/normal/silence switch to the test position or activat-

ing the alarm ﬂ oat should turn on the alarm light. If the light does

not activate, replace with same type.

Circuit Breaker (optional)

Check each pole of the circuit breaker for proper resistance reading

using the following procedure.

WARNING: Disconnect incoming power to panel.

1. Isolate the circuit breaker by disconnecting either line side or

load side wires.

2. Place the ohmmeter leads across the corresponding line and

load terminals of each pole.

3. With the ohmmeter on the R X 1 scale and the breaker in the

OFF position, the reading should be inﬁ nity (very high resis-

tance). With the breaker in the ON position, the reading should

be nearly zero ohms (very low resistance). If the readings are

not as stated, replace the circuit breaker with one of the same

ratings.

NOTE: Readings may vary slightly depending on the ac-

curacy of the measuring device.

Float Controls

Check the ﬂ oats during their entire range of operation. Clean,

adjust, or replace damaged ﬂ oats.
