How do a level switch + relay control the start and stop of a pump?
Thread Content
Hello everyone. To use a level switch and a relay to control the start and stop of a pump motor, it works as follows: when the liquid level is high, an alarm is triggered, the relay activates and the pump starts; when the liquid level is low, an alarm is triggered, the relay activates and the pump stops. Who can create a whole CAD drawing?
The operation of the actual liquid level switch and the pump is accomplished indirectly through a relay; when the system supplies power to the relay, the relay activates and the pump starts, while the process is reversed when the pump stops.
