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
2
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 monitors over and
under voltage, phase loss
phase
and
correct
sequence.
In case of N versions, the
relay monitors over and
under voltage.
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.
