Description
limit for the
BusRight V del
time
.
Information about that is
recorded into controller history.
Setpoint
BusR protect
:
BusR Volt prot
has to be set to
ENABLED if healthy bus voltage detection and history
record are requested. Voltage has to be below the
BusRight >V
limit if BTB synchronisation should be started,
because the
BusRight >V
setpoint is used for healthy bus
detection (this condition applies only if
BusR Volt prot
is set
to ENABLED).
This alarm is issued if voltage protections are based on
phase to neutral voltages. It means that
Basic settings
:
FixVoltProtSel
is set to PHASE-NEUTRAL.
BusR L12, L23 or L31 under
H
Right bus L12, L23 or L31 voltage was under the
BusRight
<V
limit for the
BusRight V del
time
.
Information about
that is recorded into controller history.
Setpoint
BusR protect
:
BusR Volt prot
has to be set to
ENABLED if healthy bus voltage detection and history
record are requested. Voltage has to be over the
BusRight
<V
limit if BTB synchronisation should be started, because
the
BusRight <V
setpoint is used for healthy bus detection
(this condition applies only if
BusR Volt prot
is set to
ENABLED)..
This alarm is issued if voltage protections are based on
phase to phase voltages. It means that
Basic settings
:
FixVoltProtSel
is set to PHASE-PHASE.
BusR L12, L23 or L31 over
H
Right bus L12, L23 or L31 voltage was over the
BusRight
>V
limit for the
BusRight V del
time
.
Information about
that is recorded into controller history.
Setpoint
BusR protect
:
BusR Volt prot
has to be set to
ENABLED if healthy bus voltage detection and history
record are requested. Voltage has to be below the
BusRight >V
limit if BTB synchronisation should be started,
because the
BusRight >V
setpoint is used for healthy bus
detection (this condition applies only if
BusR Volt prot
is set
to ENABLED).
This alarm is issued if voltage protections are based on
phase to phase voltages. It means that
Basic settings
:
FixVoltProtSel
is set to PHASE-PHASE.
BusL f under
H
Left bus frequency was under the
BusLeft <f
limit for
BusLeft f del
time
.
Under frequency protection is based on
BusL protect
:
BusLeft <f
and
BusLeft f del
setpoints.
BusL f over
H
Left bus frequency was over the
BusLeft >f
limit for
BusLeft
f del
time
.
Over frequency protection is based on
BusL
protect
:
BusLeft >f
and
BusLeft f del
setpoints.
BusR f under
H
Right bus frequency was under the
BusRight <f
limit for
BusRight f del
time
.
Under frequency protection is based
on
BusR protect
:
BusRight <f
and
BusRight f del
setpoints.
BusR f over
H
Right bus frequency was over the
BusRight >f
limit for
BusRight f del
time
.
Over frequency protection is based on
BusR protect
:
BusRight >f
and
BusRight f del
setpoints.
Vb L1, L2 or L3 under
H
Bus L1, L2 or L3 voltage was under the
Bus < Hst
limit for
Bus V del
time
.
Undervoltage protections are based on
Bus protect
:
Bus < Hst
and
Bus V del
setpoints. This
alarm is issued if voltage protections are based on phase
