11.1 Smart Card - Pump Control and Protection

The VLT® Soft Starter MCD 600 smart card is ideal for applications with extensive external inputs, such as pumping situations where
external sensors provide extra protection to the pump and motor.
In this example, the MCD 600 controls a bore pump via scheduled start/stop operation. The control panel is fitted with a 3-way selector
allowing Auto Run, Stop, or Manual Run. Three 4–20 mA transducers are used to monitor water depth, pipe pressure, and flow.
