If the relay coil in a liquid level control opens, what could result?

When the relay coil in a liquid level control opens, it typically interrupts the electrical current that signals the system to stop filling. If this relay controls a filling mechanism, opening the relay can cause an overflow condition. This occurs because the filling process may continue, incapable of stopping at the designated liquid level, resulting in excess fluid spilling over the container or system it is designed to keep filled.

In this context, the relay coil is crucial for maintaining the balance of liquid within a designated space. If the system cannot detect when to halt the filling due to the disruption from the open relay, it directly leads to an overflow. This scenario highlights the importance of proper relay functioning in liquid control systems within commercial food equipment, where precise liquid levels are essential for safety and operational efficiency.
