Installing the Float Switches
The Fusion™ Three Phase Duplex control panel operates with 3 or 4 fl oat switches to activate pump STOP, LEAD pump START, LAG pump START and high-level ALARM functions.
-
WARNING!
Ensure all power is turned OFF before installing fl oats in tank. Failure to do so could result in serious or fatal shock. -
Label each fl oat and cord end with the provided pairs of STOP, LEAD, LAG, and ALARM stickers.
-
CAUTION!
If the fl oats are not properly mounted and connected in the correct order, the pumps will not function properly.
Mounting the Control Panel
NOTE
If the distance to the control panel exceeds the length of the fl 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.
Floats require free range of motion.
They must not touch each other or any equipment in the pump chamber.
Wiring the Control Panel
-
Determine conduit entrance locations on control panel as shown. Check local codes and schematic inside the panel for the number of power circuits required.
CAUTION!
Be sure the pump power voltage and phase are the same as the pump motor being installed. -
Connect the following wires to the proper terminal positions:
• incoming power
• pump 1 and 2
• float switches
See schematic inside control panel for details. Typical Layout (May vary with options ordered).
CAUTION!
You must use conduit sealant to prevent moisture or gases from entering the panel.
Type 4X conduit must be used to maintain a Type 4X rating of the control panel. -
Verify correct operation of control panel after installation is complete.
Operation
Fusion™ Three Phase Duplex control panel operates with float switches. When
all floats are in the open or OFF position, the panel is inactive. As the
liquid level rises and closes the STOP float, the panel remains inactive until
the LEAD fl oat closes. At this point the LEAD pump will turn ON (if the Hand-
Off -Auto switch is in the AUTO mode and the power is ON). The pump will
remain ON until both the STOP and LEAD fl oats return to their OFF positions.
If the liquid level rises beyond both the STOP and LEAD fl oats to reach the
LAG float, the lag pump will turn ON (if the HandOff -Auto switch is in the
AUTO mode and the power is ON).
Both pumps will remain ON until the STOP, LEAD, and LAG floats return to their
OFF positions. If the liquid level rises to reach the ALARM float, the alarm
will be activated.

Basic Operation:
Lead Pump turns on when Float 2 closes. Lag pump turns on when Float 3 closes.
Pumps turn off when Float 1 opens.
Timer Dial: Controls lag pump delay time (0-60 seconds).
Float Out-of-Sequence: If a float closes or opens in the incorrect sequence,
the alarm will activate. The Out-of-Sequence fault will clear if the failed
float returns to the correct position.
