Emergency power supply for GD-04K

The SHT 5002 water detector for top-hat rail mounting in the fuse box or small distribution board is designed as a level controller and has 2 different detection lines. Detection line 1 is the actual level controller, which receives the functions "Fill" or "Drain" by means of a wire jumper and switches its potential-free 5 A changeover relay depending on a lower and an upper level, each of which is defined by a mini float switch. Detection line 2 works like a simple water detector and is called "overflow detector" here, i.e. as soon as water is detected by a sensor or mini-float switch, the second relay of the SHT 5002 switches over.
