DUPLEX ELECTRICAL ALTERNATING SYS TEM
All electrical sys tems must be in stalled by a qualifi ed li censed elec tri cian and ac cord ing to the Na tion al Elec tri cal
Code. (See sec tion 430-71 through 430-113 plus any oth ers that apply)
Refer to FM0712 for correct selection of Electrical Alternator.

Sequence of Operation for Duplex Panel
1. Operation can begin after the following:
- Correct voltage is supplied to Panel
- Panel is properly grounded
- Pumps are connected correctly to Panel
- Panel Circuit Breakers are closed
- Floats are installed properly
- Overload Protection is adjusted to Pump nameplate amps
- Pump HOA Switches are set to “Auto”
- Control On/Off Switch is set to “On”
2. When the “Stop” and “Lead” fl oats are closed Pump 1 will energize
and the Pump 1 Pump Run Light will illuminate. Pump 1 will remain
operational until the “Stop” fl oat opens.
3. The next time the “Stop” and “Lead” fl oats are closed the Alternating
Circuit will energize Pump 2 and the Pump 2 Pump Run Light will
illuminate. Pump 2 will remain operational until the “Stop” fl oat opens.
This cycle will repeat each time the fl uid level rises and falls.
4. If the fl uid level continues to rise after the fi rst pump has been ener-
gized the “Lag” fl oat will close. When the “Lag” fl oat has closed the
second Pump will Energize. Both Pumps will remain operational until
the “Stop” fl oat opens.
5. In a three fl oat system when the “Lag” fl oat is closed the following will
also occur:
- The External High Water Light will illuminate
- The Audible High Water Horn will sound
- The Auxiliary Dry Contacts will close
6. In a four fl oat system, the alarm fl oat should be the third fl oat causing
an alarm to sound when the lead pump fails to operate or the rate of
in fl ow into the basin exceeds the capacity of one pump. When the
alarm fl oat is closed the following will occur.
- The External High Water Light will illuminate
- The Audible High Water Alarm will sound
- The Auxiliary Dry Contacts will close
As the liquid level continues to rise the fourth fl oat will close, energizing
the lag pump. The lag pump and the lead pump will remain energized
until the "Stop" fl oat opens.
NOTE: In Duplex systems where it is considered normal for two pumps
to operate in tandem during peak fl ow conditions, the third and fourth
fl oat may be re versed.
7. The Audible High Water Horn can be silenced by pressing the Alarm
Si lence Button. When the “Alarm” fl oat opens the External High
Water Light, Audible High Water Horn and Dry Auxiliary Contacts will
be reset.
