Once the voltage drops below 5 to 50% of the treshold (hysteresis), the output relay changes state again instantly. Changing the hysteresis onthe front face does not therefore modify the value of the preset treshold. o Legend N Treshold Ue Hysteresis UPPER function UNDER function Unit power-up Controlled voltage Principles Unless otherwise specified, the characteristics given are applicable to all or part of the product range selected
