OPERATION
Control Functions
Standard Constant Pressure Operation
Drive Running
When the SubDrive/MonoDrive Connect is controlling the motor and
pump, the display will be illuminated and the following information
will be shown on the display:
•
System Pressure (1): When using a pressure transducer, the
system displays a numerical pressure reading (in PSI), followed
by a "P" suffix to distinguish it from motor speed. The "P" will
steadily flash on and off when the drive is running the motor.
•
Motor/pump speed (2): When using a standard pressure sen-
sor, the system displays the current motor speed (in Hz).
System Idle
When the SubDrive/MonoDrive Connect is powered on and idle (not
pumping water), the display will be illuminated and the following
will be shown on the display:
•
System Pressure: When using a pressure transducer,
the system displays the resting pressure reading with the "P"
steady (not flashing).
•
Motor/pump speed (3): When using a standard pressure sen-
sor, the system displays three dashes "– – –" indicating that the
motor is not running.
Fault Detected (4)
When a fault condition is detected in the system, the drive display
will illuminate red and the fault code will be displayed. Fault codes
begin with "F" followed by a one- or two-digit number. Refer to
"Diagnostic Fault Codes" on page 43
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 system 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 36
to activate and set the cut-in pressure.
