Controlled voltage
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. 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.
