The under or overvoltage threshold value is set by a graduated potentiometer by reading the Un scale to be monitored directly.
The hysteresis is set by a graduated potentiometer from 5 to 20 % of the preset threshold. The hysteresis value cannot be higher than the extremes of the measurement range.
In overvoltage mode, if the controlled voltage exceeds the preset threshold for longer than the time set on the front face (0.1 to 10 s), the output relay opens and LED R is extinguished. During the
time delay, this LED flashes.
Once the voltage falls below the threshold value minus the hysteresis, the relay closes instantaneously.
In undervoltage mode, if the controlled voltage falls below the preset threshold for longer than the time set on the front face (0.1 to 10 s), the output relay opens and LED R is extinguished. During
the time delay, this LED flashes.
Once the voltage rises above the threshold value plus the hysteresis, the relay closes instantaneously.

If "with memory" mode has been selected, the relay opens and stays in this position when threshold crossing is detected. The power supply must be disconnected to reset the product.
MUSF relays operate in window mode : they check that the controlled voltage stays between a minimum and maximum threshold.
The under and overvoltage threshold values are set by two graduated potentiometers by reading the Un scale to be monitored directly.
The hysteresis is fixed, value : 3 % of the preset thresholds.
If the controlled voltage exceeds the preset upper threshold, or falls below the preset lower threshold for longer than the time set on the front face (0.1 to 10 s), the output relay opens and LED R is
extinguished. During the time delay, this LED flashes.
Once the voltage returns to below the upper threshold value minus the hysteresis, or above the lower threshold value plus the hysteresis, the relay closes instantaneously.
When the unit is powered up with a measured fault, the relay stays open.
