Mode of Operation
Connected to the 3 phases (and neutral) DPB01 and PPB01 operate when all 3 phases are present at the same time, the phase sequence is correct (not N versions) and the phasephase (or phase-neutral) voltage levels are within set limits. 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) The relay monitors over and under voltage, phase loss phase and correct sequence. In case of N versions, the relay monitors over and under voltage. 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.

Note
When DPB01 or PPB01 is used with phase indicator lamps (see examples in the following diagrams), the lamp H1 or H2 might be dimly lit when there is a phase loss in L1 or L2. This might happen if the lamps used are the typical low power indicator lamps, and there are no other loads present. This fact can be avoided by using W4 models. Note that the neutral must be always connected to the device. DPB01
