Installing the Float Switches
The Model 112 Single Phase Simplex control panel operates with
3 oat switches to activate pump STOP, START, and high-level
ALARM functions.

CAUTION!
NOTE
Ensure all power is turned OFF
before installing oats in tank.
Failure to do so could result in
serious or fatal shock.
Label each oat and cord
end with the provided pairs
of STOP, START, and ALARM
stickers.
If the distance to the control panel exceeds the length of
the oat switch cords or the pump power cord, splicing
in a liquid-tight junction box will be required. For outdoor
or wet installation, we recommend an SJE Rhombus UL
Type 4X junction box.

Make sure hose clamp
band does not interfere
with oat operation.
Do not install cord under
hose clamp.
Tighten
the
clamp.
Hose clamp is 18-8
stainless steel.
If the oats are not properly mounted and connected in the correct
order, the pumps will not function properly.
Floats require free range of motion.
They must not touch each other or any equipment in the pump chamber.

Operation
SJE-Rhombus® Model 112 Single 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 inactive until
the start oat 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 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 alarm will be
activated. The alarm horn can be silenced by pressing and
releasing the test/silence switch.
Alarm System (Indicator Light and Horn)
When an alarm condition occurs, the red light and horn will
be activated.
If the TEST/NORMAL/SILENCE switch is moved to the
SILENCE position and released, the horn will be silenced.
When the alarm condition is cleared, the alarm system is
reset.
Hand-O-Auto (HOA) Switch
The HOA 3-way switch controls pump functions.
In HAND mode, the pump will turn ON.
OFF turns the pump OFF.
In AUTO mode, commands from the oat
switches turn the pump ON and OFF.
Auxiliary Contact
Form C - Can be wired normally open or normally closed.
Circuit Breaker (optional)
The circuit breaker provides pump disconnect and branch
circuit protection.
Motor Contactors
The motor contactor controls the pump by switching
electrical lines.
Wiring the Control Panel
1Determine conduit entrance locations on control panel as shown.
Check local codes and schematic inside the panel for the number
of power circuits required.
Be sure the pump power voltage and phase are the same as the
pump motor being installed.
2Connect the following wires to the proper terminal positions:
• incoming power
• pump
• oat switches
See schematic inside control panel for details.
