    The EMX4i smart card can be used to control start/stop activation of the starter, based on information from external inputs. In this example, the EMX4i controls a pump which fills a tank, with maximum and minimum water levels. A pressure sensor is used to monitor the level of water in the tank and trigger the pump to fill the tank when water drops below the minimum level, and shut off the pump when the maximum water level is reached.
