Question

How does the Floatless Level Controllers "61F"operate when the power returns after power failure?

Answer

If the power fails while the self-holding circuit is set to ON, the self-holding circuit is turned OFF and kept in the OFF state even after the power recovers. Therefore, when using the Floatless Level Controller "61F-GN", in the automatic operation of water supply, the pump is ON until the level of water reaches the Electrode "E1".

Meanwhile, in the automatic operation of water drainage, the pump is not turned ON until the level of water reaches the E1.
