The relay monitors its own supply voltage. It controls:
- Undervoltage, adjustable from -20 to -2% of Un (-12 to -2% over the 3 x 208 V AC range and -17% to -2% for the 3 x 220 V AC range due to the minimum voltage 183 V AC)
- Overvoltage, adjustable from +2 →+20% (+2 →+10% over the 3 x 480 V AC range due to the maximum voltage 528 V AC).
An adjustable time delay from 0.3 to 30s can be used to disable the output relay during a transient fault.
In the event of a voltage fault, the relay opens at the end of the time delay set by the user.
In the event of phase failure, the relay opens instantaneously, without waiting for the end of the time delay.
When the unit is powered up with a measured fault, the relay stays open.
