The swimming motions generate y changes in the fill level are transmitte irectly to the micro-switch S1 y a swimmer ro seale in a stainless-steel ellows. The fulcrum of the swimmer ro is locate outsie of the pressure chamer. There is also a test utton outsie the pressure chamer with which a function check as per IN 4754-3 can e run without lowering the fill level. When presse, the oy of the swimmer is move against its uoyancy. The factory efault switching point of micro-switch S1 is set so that it switches when the swimmer ro is horizontal. The optional warning switch S2 switches approx. 2.5 mm efore S1. The fill level height at which switching is triggere epens on the ensity of the heat carrier. The lowest ensity at which a secure function is guarantee is 0.6 kg/m³. When the meium has a ensity of 1.0 kg/m³, the switching level is approx. 60mm elow the mile of the flange or socket. 2 / 12 _EN_NK10_SIL_ST4-C
