Pump Genius Multipump floating control for five pumps in parallel. Power connection of the Pump Genius Multipump floating control for five pumps in parallel. CANADIAN AUTOMATION pump application, you can detect the fault with the internal parameters of VFD which could be more effective in compare to some vibration protection sensors. Differential pressure of filters can be connected to VFD with SoftPLC and get respective alarm or fault trip as required.set pressure or flow rate. As VFD has DI, AI, you can have a lots of interlocks for safety and similar to pump application, you can detect the fault with the internal parameters of VFD which could be more effective in compare to some vibration protection sensors.Traditionally, damper can be used for air flow or pressure control, and for fan protection you should be VOLUME 2, ISSUE 3 15
