G.9 iQpump Software Multiplexing Set-up
◆ Application Examples
■
Simple Duplex System
A customer requires a duplex system with the following capabilities:
• Control the system pressure using 2 iQpump drives (no PLCs).
• Alternate iQpump drives everyday to even out the pump wear.
• Toggle switch for Run command.
• Each iQpump drive will have its own feedback transducer and because of shut-off valves, the network feedback as a back-up should not be used.
• 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.
