SubDrive/MonoDrive Connect
NOTE: This knob is only compatible with the default 4-20mA 100 PSI analog pressure
transducer. If using an analog pressure transducer with a different range, the FE Connect
DIP switch (DIP Switch 1 – Position 1) must be in the ON/UP position and the Pressure
Transducer Type, Pressure Transducer Range, and Pressure Setpoint parameters must
be configured using the FE Connect mobile app. Refer to the Advanced Setup section for
more information.
For SubDrive Pressure Sensor
The pressure sensor communicates the system pressure to the SubDrive/MonoDrive
controller. The sensor is preset at the factory to 50 psi (3.4 bar), but can be adjusted by the
installer using the following procedure:
a. Remove the rubber end-cap.
b. Using a 7/32" Allen-wrench (provided), turn the adjusting screw clockwise to
increase pressure and counter-clockwise to decrease pressure. The adjustment
range is between 25 and 80 psi (1.7 and 5.5 bar). Note: 1/4 turn = approximately
3 psi (0.2 bar).
c. Replace the rubber end cap.
d. Cover the pressure sensor terminals with the rubber boot provided. Do not place
boot in direct sunlight.
Underload Sensitivity (if needed)
The Underload Sensitivity MUST be adjusted only when the SubDrive/MonoDrive is
POWERED OFF. The new setting will not take effect until the drive is powered up.
The SubDrive/MonoDrive controller 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 shallow wells) this trip level may result in nuisance faults. If the pump is installed
in a shallow well, activate the controller and observe system behavior. Once the controller
begins to regulate pressure, check operation at several flow rates to make sure the default
sensitivity does not induce nuisance Underload trips.
If it becomes necessary to desensitize the Underload trip level, remove power and wait five
minutes for the controller to discharge. Once the internal voltages have dissipated, locate
the Underload Potentiometer on the upper-right corner of the User Interface Board as
shown in the figure on the next page.
