Monitoring Functions
The system display shows the current status of the system in real time, including:
• System status: Running, Idle, Faults
• System pressure or motor speed
• Wi-Fi connection status
Additional information is available using the FE Connect Mobile App. Refer to

Protection Features

Power Factor Correction

Active Power Factor Correction (PFC) minimizes input RMS current by allowing the drive to draw a cleaner,
sinusoidal input current waveform. This allows for a reduction in input power cable size when compared to
similar applications without power factor correction, because less average current is used by the drive for a
given load when compared to non-PFC devices.

Over Temperature Foldback

The system is designed for full power operation in ambient temperatures up to 122 °F (50 °C) at nominal
input voltage. In extreme thermal conditions, the controller will reduce output power in an attempt to avoid
shutdown or damage while still trying to provide water. Full output power is restored when the internal con-
troller temperature cools to a safe level.
NOTE: Motor over-temperature sensing is not provided by the drive.

Motor Soft Start

When the drive detects that water is being used, the drive starts and increases the motor speed slowly,
gradually increasing voltage, resulting in a cooler motor and lower start-up current compared to conven-
tional water systems. In those cases where the demand for water is small, the system may cycle on and off
at low speed. Because of the soft-start feature, this will not harm the motor or the pressure sensor.

Motor Overload Protection

The drive electronics provide motor overload protection by preventing motor current from exceeding the
maximum Service Factor Amps (SFA).

Broken Pipe Protection

When enabled, the Broken Pipe Detection feature will stop the system and display Fault 14 if the drive runs
at full power for a user adjustable time period without reaching the pressure setpoint.
If the system is used with a sprinkler system or is being used to fill a pool or cistern, the feature should be
disabled.
This feature is enabled and adjusted using the FE Connect app. Refer to

Adjustable Underload Off Time (App Only)

The Underload Off Time determines how long the drive will wait before attempting to run following an
Underload event. The default time is 5 minutes, but is user-adjustable through the FE Connect app from 1
minute to 48 hours.
