Mode of Operation
Connected with the 3 phas-
es (and neutral) DPB02 and
PPB02 operate when all 3
phases are present at the
same time, the phase
sequence is correct and the
asymmetry is under the set
level.
Asymmetry is defined as fol-
lows:
when measuring phase-
phase voltages and also as
follows:
when measuring phase-neu-
tral voltages.
If the asymmetry exceeds
the set level the red LED
starts flashing 2 Hz and the
output relay releases after
the set time period. If the
phase sequence is incorrect
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 after
the alarm condition occurs.
Example 1
(mains network monitoring)
The relay monitors asymme-
try, phase loss and correct
phase sequence.
Example 2
(load monitoring)
The relay releases in case of
interruption of one or more
phases or when the asym-
metry exceeds the set level.
