Simple Duplex System Application Example

A customer requires a duplex system with the following capabilities:
• Control the system pressure using two drives (no PLCs).
• Alternate drives everyday to even out the pump wear.
• Toggle switch for Run command.
• Each drive will have its own feedback transducer. Due to the shut-off valves, the network feedback should not be used as a

backup.

• Pump is at optimal running speed when running at fixed speed is 54.0 Hz.
• Setpoint is 100 PSI, feedback scale is 145 PSI, start level is 80 PSI.
