4. Test the Ramp Rate (R) value by opening the shut-off valve after the pressure sensor, wait for
the system to stabilize, and then close the shut-off valve to monitor the shut-off time.
• If the shut-off time is less than 60 seconds, the R value is good.
• If the shut-off time is more than 60 seconds, increase the R value. If the maximum R value
is reached, increase the minimum frequency.
5. Make sure the system can regulate on minimum flow by closing all faucets except the one with
the least flow and open the shut-off valve after the pressure sensor. Verify that the system
reaches initial pressure within 10psi, stabilizes within 10 seconds, and shuts off within 60 sec-
onds.
Underload
These settings replace the Underload potentiometer when using the FE Connect mobile app for
setup. In addition, the app provides more detailed control of the feature.
• Underload, Off Time
• Prime Delay (Surface applications only): Selectable from 0 to 5 minutes.
Refer to "Underload Sensitivity" on page 29
Duplex Alternator
Configuration: This selection enables the duplex feature and sets
the identity of each drive in the network.
• Standalone (drives will operate independently)
• Pump 1
• Pump 2
Switching Interval: This parameter sets the run time (hours)
before the lead and lag roles alternate. The Pump 1 drive setting
controls the entire system.
• 1 to 24 hours
• Default = 1 hour

Alternator feature.
Advanced Options
Pressure Bump Mode: Bump mode controls how hard the drive will pump just before stopping the
motor when the pressure setpoint is reached.
For applications with a large pressure tank, or if the system takes too long to stop, the bump mode
can be modified to be more aggressive. The system behavior should be monitored when adjusting
these settings to ensure proper operation.
• Standard, Aggressive, or Off.
Tank Size: Use this setting to refine system performance when using a standard pressure sensor.
Select either:
• Small Tank, Large Tank
Steady Flow: Select either Normal Performance or Reduced performance.
