10.2 Smart Card - Level Controlled Pump Activation
The ASA 4.0 Advanced smart card can be used to control start/stop activation of the starter, based on information from external inputs.
In this example, the ASA 4.0 Advanced 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.
