Duplex Alternator Feature

Configuration

SubDrive/MonoDrive Connect models support the built-in Duplex Alternator functionality. This
function requires an appropriate communication cable to be installed between two SubDrive/
MonoDrive Connect units.
Before the Duplex Alternator function will operate, each drive must be configured individually
using the FE Connect mobile app. The initial lead drive must be configured as Pump 1 and the initial
lag drive must be configured as Pump 2. Refer to
mation.
• Standalone (drives will operate independently)
• Pump 1
• Pump2
When using the Duplex Alternator function with pressure transducers, the Primary Setpoint of
Pump 1 must be set to the desired system pressure. The drive configured as Pump 1 will automati-
cally control the pressure set point of the controller configured as Pump 2, setting it to 5 PSI lower
than the primary system set point.
When using the Duplex Alternator function with pressure switches, the pressure switch connected
to the drive configured as Pump 1 must be set at least 3 PSI higher than the pressure switch con-
nected to the drive configured as Pump 2.
IMPORTANT: When using the drawdown function, the same cut-in pressure must be configured on
both drives.

Switching Interval

When operating two drives using the Duplex Alternator function, this parameter sets the accumu-
lated run time (hours) before the lead and lag systems will alternate roles.
• 1 to 24 hours
• Default = 1 hour
The Switching Interval time setting on the controller configured as Pump 1 sets the interval time for
the overall system.
When the Duplex Alternator function is operating, the status of the Duplex Alternator system is
shown on the Monitor screen of the app. The roles of the lead and lag pump can be manually
switched by pressing the Switch Pumps button in the FE Connect app.
