Steady Flow Selection - Franklin Electric SubDrive15 Manuel D'utilisation

SubDrive/MonoDrive
Underload Sensitivity: Shallow Set
If the pump is installed in an extremely shallow (i.e. artesian) well and the system
continues to trip, then the Underload Potentiometer (Pot) will need to be adjusted
clockwise to a lower sensitivity setting. Check the Underload trip level and repeat
as necessary.
Underload Sensitivity: 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 Pot will need to be adjusted clockwise to a
higher sensitivity setting.

Steady Flow Selection

The SubDrive/MonoDrive controller is configured at the factory to ensure quick response
to maintain constant pressure. In rare cases (as with a water line tap before the pressure
tank), the controller may need to be adjusted to offer better control.
If the controller is used on a system that has a water line tapped before the pressure tank
and close to the well head or where audible speed variations of the PMA can be heard
through the pipes, adjusting the pressure control response time may be necessary. After
enabling this feature, the installer should check flow and pressure changes for possible
overshoot. A larger pressure tank and/or wider margin between regulation and pressure
relief valve pressure may be required as the Steady Flow Features reduce the controller's
reaction time to sudden changes in flow.
If it is necessary to adjust the pressure control, remove power and allow the controller
to discharge. Wait 5 minutes to allow internal voltage to dissipate, locate the DIP switch
marked "SW1". Move DIP SW1 Position 4 to "ON" (up) position.
