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 N Legend Treshold Ue Hysteresis UPPER function UNDER function Unit power-up Controlled voltage Principles When the value of the controlled voltage, AC or DC, reaches the treshold Ue displayed on the front face, the output relay changes state at the end of a time delay T1, which can be set on the front face at between 0.1 and 3s and remains latched in this position. o Legend N Treshold Ue Hysteresis UPPER function UNDER function Unit power-up Controlled voltage *** TRADUCTION MANQUANTE *** Dimensions (mm) EUL / EUH Unless otherwise specified, the characteristics given are applicable to all or part of the product range selected
