Steady Flow Selection (Dip Sw1 - Position 4); Tank Size And Bump Mode Adjustments (Fe Connect App Only) - Franklin Electric SubDrive 50 Manual Del Usaurio

DRIVE CONFIGURATION
Performance Settings
Deep Set: In cases where the pump is set very deep, run the system at open discharge to pump the well
down and observe carefully that an Underload is detected properly. If the system does not trip as it should,
then the Underload potentiometer will need to be adjusted clockwise to a higher sensitivity setting.
The Underload Sensitivity MUST be adjusted only when the drive is POWERED OFF. The new setting will not
take effect until the drive is powered up.
Off Time (App only): This setting determines how long the drive will wait before attempting to run following
an Underload event. The default time is five minutes, but is user-adjustable from one minute to 48 hours
using the FE Connect mobile app.
Steady Flow Selection (DIP SW1 – Position 4)
The drive is configured at the factory to ensure quick response to maintain constant pressure. In some cases,
when using a pressure sensor, the drive may need to be adjusted to offer better control through a slower
response time.
For example, if the system has a water line tapped before the pressure tank or close to the well head, or
where audible speed variations of the pump assembly can be heard through the pipes, adjusting the pres-
sure control response time by enabling the Steady Flow feature may be helpful. After enabling this feature,
the installer should check flow and pressure changes for possible overshoot. A larger pressure tank and/or a
wider margin between the regulated pressure and the pressure relief valve pressure may be required
because the Steady Flow feature reduces the drive's reaction time to sudden changes in flow.
To activate the Steady Flow feature, remove power and allow voltage to discharge. Move DIP SW1 Position 4
to the SF (up) position. The new setting will not take effect until the drive is powered up.
NOTE: The Steady Flow feature is operational only when using a standard pressure sensor. If DIP SW1 Posi-
tion 5 is in the XDCR (down) position, the Steady Flow selection is ignored (no fault occurs).
IMPORTANT: When Steady Flow is enabled, Bump Mode is automatically disabled.

Tank Size and Bump Mode Adjustments (FE Connect App Only)

Using the FE Connect App, the bump mode and tank size settings of the drive can be changed. 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.
