If one or more phase-phase or phase-neutral voltages exceeds the upper set level or drops below the lower set level, the red LED starts flashing 2 Hz and the output relay releases after the set time period. In any case if phase-neutral measurement is selected both phasephase and phase-neutral voltages are monitored. If the phase sequence is wrong or one phase is lost, the output relay releases immediately. Only 200 ms delay occurs. The failure is indicated by the red LED flashing 5 Hz during the alarm condition. Example 1 (mains network monitoring) Example 2 (load monitoring) The relay releases in case of interruption of one or more phases, when one or more voltages drop below the lower set level or exceed the upper set level. The relay monitors over and under voltage, phase loss and correct phase sequence.
