Selection of asymmetry and
time delay:
Centre knob:
Setting of asymmetry on rela-
tive scale.
Lower knob:
Setting of delay on alarm time
on absolute scale (0.1 to 30 s).
Function/Range/Level and Time Delay Setting
DPB02, PPB02
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,
sequence is correct and the
asymmetry is under the set
level.
Asymmetry is defined as fol-
lows:
the
phase
when
phase voltages and also as
measuring
phase-
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. In any
case if phase-neutral mea-
surement is selected both
phase-phase
neutral voltages are moni-
and
phase-
tored. 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.
