OPERATION
Monitoring Functions
Tank Fill, Drain, and Level Control (Float Switches)
The SubDrive Connect can use float switches connected to the Auxiliary Inputs to maintain water levels
in a tank. Refer to "Drive Control Using an External Device (Auxiliary Input)" on page 41
information.
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
page 48.
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 104 °F (40 °C) at nominal
input voltage. In high temperature conditions (above 104 °F / 40 °C) the VFD reduces output power in
an attempt to avoid shutdown or damage; however, product life and system performance will still be re-
duced. A thermometer icon is shown in the display when the VFD is in Over Temperature Foldback
mode. Full output power is restored when the internal drive temperature cools to a safe operating level.
NOTE: Motor over-temperature sensing is not provided by the drive.
Motor Soft Start
When the drive detects that water is being used, it starts and increases the motor speed gradually, in-
creasing voltage, resulting in a cooler motor and lower start-up current compared to conventional water
systems. In situations 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 VFD electronics provide motor overload protection by preventing motor current from exceeding the
maximum Service Factor Amps (SFA) programmed in settings.
