NOTICE
Risk of damage to drive or water system can occur due to improper adjustment
or settings.
• System behavior should be monitored when adjusting any of these settings to ensure
proper operation.
• Confirm that an adequate pressure relief valve is included in the system.
Drawdown Feature (FE Connect App Only)
When using a pressure transducer, an optional "cut-in" pressure can be set to allow for more water to
be drawn from the tank. For example, a system setpoint pressure of 50 PSI and a cut-in pressure of 30
PSI would cause the drive to maintain system pressure at 50 PSI when running; however when the sys-
tem is idle, the drive will not start the motor until the system pressure drops below 30 PSI.
Refer to "Drive Configuration Using the FE Connect App" on page 44
pressure.
System Response (DIP SW3)
When using a pressure transducer with a surface pump application, the system response can be adjusted
as follows:
System Response
Proportional Gain (P)
Integration Time (I)
Ramp Rate (R)
Select one DIP switch for preset F F A A S S T T , M M E E D D , or S S L L O O W W system response parameters. Selecting more than
one switch will result in an Invalid DIP Switch Fault (F24). If no selection is made, the system will default
to S S L L O O W W (no fault occurs).
M M i i n n i i m m u u m m F F r r e e q q u u e e n n c c y y : : In surface pump applications, placing DIP SW3 Position 6 in the O O F F F F (down) po-
sition will set the minimum output frequency to 30 Hz (default). Move the switch to the O O N N (up) position
to set the minimum output frequency to 15Hz. Refer to
on page 44 for more precise settings.
Underload Sensitivity
The drive is configured at the factory to ensure detection of Underload faults in a
wide variety of pumping applications. In rare cases (as with certain pumps in shal-
low wells), this trip level may result in unnecessary faults. If the pump is installed
in a shallow well, activate the drive and observe system behavior. Once the system
begins to regulate pressure, check operation at several flow rates to make sure the
default sensitivity does not cause false Underload trips.
If it becomes necessary to adjust the Underload trip level, remove power and wait
five minutes for the controller to discharge. Once the internal voltages have dissi-
pated, locate the Underload Potentiometer on the upper-right corner of the User
Interface Board.
S S h h a a l l l l o o w w S S e e t t : : If the pump is installed in an extremely shallow (i.e. artesian) well and the system continues to trip, then adjust
the Underload Potentiometer counter-clockwise to a lower sensitivity setting. Check the Underload trip level and repeat as
necessary.
