Installing the Float Switches
The Model 123 Single Phase Duplex control panel operates with
oat switches. They activate pump STOP, LEAD pump START,
LAG pump 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.
If the oats are not properly mounted and connected in the correct
order, the pumps will not function properly.
Label each oat and cord end
with the provided pairs of
STOP, LEAD, LAG, 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.

Wiring the Control Panel Operation
SJE Rhombus Model 123 Single Phase Duplex control panel
operates with oat switches. When all oats are in the
open or OFF position, the panel is inactive. As the liquid
level rises and closes the STOP oat, the panel remains
inactive until the LEAD oat closes. At this point the LEAD
pump will turn ON (if the Hand-O-Auto switch is in the
AUTO mode and the power is ON). The pump will remain
ON until both the STOP and LEAD oats return to their OFF
positions. If the liquid level rises beyond both the STOP
and LEAD oats to reach the LAG oat, the lag pump will
turn ON (if the Hand-O-Auto switch is in the AUTO mode
and the power is ON). Both pumps will remain ON until the
STOP, LEAD, and LAG oats return to their OFF positions.
If the liquid level rises to reach the ALARM oat, the alarm
will be activated.
Alarm System (Indicator Light and Horn)
When an alarm condition occurs, the red light and horn will
be activated.
Circuit Breakers (optional)
Circuit Breakers provide pump disconnect and branch
circuit protection.
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.
Motor Contactors
Motor contactors control pumps by switching electrical lines.
Capacitor Start Modules
Start/run capacitor kits must be ordered separately.
Auxiliary Contact
Form C - Can be wired normally open or normally closed.
Hand-O-Auto (HOA) Switches
The HOA 3-way switches control pump functions.
In HAND mode, the pump will turn ON.
OFF turns the pump OFF.
In AUTO mode, commands from the oat switches
turn each pump ON and OFF.
1Determine conduit entrance locations on control panel as shown.
Check local codes and schematic on the inside cover of 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 1
• pump 2
• oat switches
See schematic on inside cover of the control panel for details.

Type 4X conduit must be used to maintain a Type 4X rating of
the control panel.
You must use conduit sealant to prevent
moisture or gases from entering the panel.
