Flint & Walling Commander 3 Manual

Commander® 3 Variable
Speed Controller System
Instructions
The Commander® 3 Variable Speed Controller is a dependable
water system Variable Frequency Drive (VFD) that uses custom
programming to enhance the performance of single phase 3-Wire
& 3-phase submersible pumps as well above ground 3-phase
pumps. When applied correctly, the drive eliminates pressure
cycling associated with conventional pressure switch-controlled
water pumping systems and provides a constant output pressure.
Key features of the drive controller include:
• Can use either a pressure switch (no snap action) or a
4-20mA transducer as the pressure control.
• Constant water pressure with a wide range of settings (30-
80 psi) (Note: The maximum obtainable system pressure is
limited by the performance of the pump installed)
• Smaller pressure tank can be used.
• Can be used with F&W as well as industry standard 3-wire
single phase submersible motors as well as 3-Phase
submersible motors or above ground pumps with 3-phase
motors.
• Fits the pump to the application – pump speed is controlled
to provide the optimum performance without overloading the
motor.
• Low in-rush (power-on transient) current
Rules for safe installation and operation.
Read these warnings and instructions carefully. Failure to follow them could cause serious bodily injury and/or property damage.
Follow all local electrical and safety codes as well as
the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).
The power supply should be a separate circuit, independent
of all other circuits. Be sure it is equipped with a fuse and
disconnect box of ample capacity.
