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.
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.

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.
