11.2 Smart Card - Level Controlled Pump Activation
The VersiStart p III smart card can be used to control start/stop activation of the
starter, based on information from external inputs.
In this example, the VersiStart p III 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.
A three-way selector switch allows the user to override sensor-based control, and
manually start or stop the motor.
