Datasheet

Set the selector switch to the 3-phase network voltage Un.
The position of this selector switch is only taken into account when the unit is powered up.
If the switch position changes while the unit is operating, all the LEDs flash but the product continues to work normally with the voltage selected on energisation prior to the change of position.
The LEDs return to their normal state if the switch is reset to its initial position defined before the last energisation.
The relay controls:
- correct sequencing of the three phases
- failure of one of the three phases (U measured < 0.7 x Un).
- undervoltage, adjustable from -2 to -20% of Un (-2 to -12% across the 3 x 208 V range and -2 to 17% for the 3 x 220 V range due to the minimum voltage 183 V AC).
In the event of a phase sequence or failure fault, the relay opens instantaneously.
In the event of a voltage fault, the relay opens at the end of the time delay set by the user.
When the unit is powered up with a measured fault, the relay stays open.
