Installing the Float Switches
The Fusion™ Three Phase Duplex control panel operates with 3 or
4 oat switches to 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.
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 a CSI Controls UL
Type 4X junction box.

Operation
Fusion™ Three 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.
If the TEST/SILENCE button is pressed when alarm is
present, it will silence the horn until the alarm condition is
reset. If the alarm is not present, the TEST/SILENCE button
will activate the alarm until the button is released.
Hand-Off -Auto (HOA) Switches (Not pictured)
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.
Motor Protective Switches
Each pump circuit has motor protective switches that
provides pump disconnect, overload, and branch circuit
protection. Adjust overload to pump FLA.
Transformer
The transformer converts incoming three phase power to
120V to be used for control and alarm.
Motor Contactors
Motor contactors control pumps 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 1 and 2
• oat switches
See schematic inside control panel for details.
