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
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
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.
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.
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.
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.
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.
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
