Mode of Operation
Asymmetry definition.
Asymmetry is an indicator of
the mains quality and it is
defined as the absolute val-
ue of the maximum devia-
tion among the mains volt-
ages, divided by the nominal
voltage of the 3-phase sys-
tem. The definition changes
according to the voltage ref-
erence:
1) in case of measuring
2) in case of measuring

Tolerance definition.
Tolerance is another indicator
of the mains quality and it is
definied as the absolute val-
ue of the maximum deviation
of the mains voltages from
the nominal voltage, divided
by the nominal voltage of the
3-phase system. The defini-
tion changes according to
the voltage reference:
1) in case of measuring
2) in case of measuring

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 mon-
itor upper and lower voltage
level of each phase or their
asymmetry and tolerance.
Voltage level monitoring:
if one or more phase-phase
or
exceed the upper set level
or drop below the lower set
level, the red LED starts
flashing
respective
releases after the set time
period.
Asymmetry and tolerance
monitoring:
if one or more phase-phase
or
exceed the set levels the red
LED starts flashing 2 Hz and
the respective output relay
releases after the set time
period.
Note: For both functions, if
the
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.

Example 1
(Mains monitoring - over and

The relay monitors over and

and

Example 2
(Motor monitoring - starting
and operating load -asym-
metry
phase-neutral voltage)
DPC01 and PPC01 ensure
correct starting and operat-
ing conditions. They monitor
the
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
detects the failure and reacts
due to excessive imbalance
among the phases.
