DPC01, PPC01
Mode of Operation
Connected to the 3 phases
(and neutral) DPC01 and
PPC01 operate when all 3
phases are present at the
same time and the phase
sequence is correct. It can
be decided whether to moni-
tor upper and lower voltage
level of each phase or their
asymmetry and tolerance. In
any case if phase-netural

both
phase-phase
phase-neutral voltages are
monitored.
Asymmetry is defined as fol-

and also as
when measuring phase-neu-
tral voltages.
Voltage level monitoring: if
one or more phase-phase or
phase-neutral voltage exceeds
the upper set level or drops
below the lower set level, the
red LED starts flashing 2 Hz
and the respective output
relay releases after the set
time period.
Asymmetry and tolerance
monitoring: if one of them
exceeds the set level the red
LED starts flashing 2 Hz and
the respective output relay
releases after the set time
period.
If
sequence is wrong or one
phase is lost, both output
relays release immediately.
Only 200 ms delay occurs.
The failure is indicated by the
red LED flashing 5 Hz during
the alarm condition.

phase
Example 1
(mains - over and under
phase-phase voltage - moni-
toring)
The relay monitors over and
under voltage, phase loss
and correct phase sequence.
Example 2
(starting and operating load -
asymmetry and tolerance
phase-neutral - monitoring)
DPC01 and PPC01 ensure
correct starting and operat-
ing conditions. They monitor
the voltage level, phase
sequence (correct direction
of the motor rotation) and
asymmetry.
Frequent failures are fuse
blowing and incorrect volt-
age level. In case of fuse
blowing the motor regener-
ates a voltage in the inter-
rupted phase. These relays
detect the failure and react
due to excessive imbalance
among the phases.
