Description
during synchronisation and you may need to adjust their
setting.
Actual state of synchronization is visible on the controller
measurement screen with synchroscope where speed and
voltage regulators' outputs, slip frequency and generator
and mains/bus voltages can be observed during the
synchronization process.
BOC L1, L2 or L3 under
A+H
Generator L1, L2 or L3 voltage was under the Gen <V
BOC limit for Gen V del time. Undervoltage protections
are based on Gener protect: Gen <V BOC and Gen V del
setpoints. 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.
19
BOC L1, L2 or L3 over
A+H
Generator L1, L2 or L3 voltage was over the Gen >V BOC
limit for Gen V del time. Overvoltage protections are
based on Gener protect: Gen >V BOC and Gen V del
setpoints. 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.
19
Sd L1, L2 or L3 over
A+H
Generator L1, L2 or L3 voltage was over the Gen >V SD
limit for Gen V del time. Overvoltage protections are
based on Gener protect: Gen >V SD and Gen V del
setpoints. 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.
19
BOC L12, L23 or L31 under
A+H
Generator L12, L23 or L31 voltage was under the Gen <V
BOC limit for Gen V del time.. Undervoltage protections
are based on Gener protect: Gen <V BOC and Gen V del
setpoints. 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.
19
BOC L12, L23 or L31 over
A+H
Generator L12, L23 or L31 voltage was over the Gen >V
BOC limit for Gen V del time. Overvoltage protections are
based on Gener protect: Gen >V BOC and Gen V del
setpoints. 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.
19
Sd L12, L23 or L31 over
A+H
Generator L12, L23 or L31 voltage was over the Gen >V
SD limit for Gen V del time. Overvoltage protections are
based on Gener protect: Gen >V SD and Gen V del
setpoints. 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.
19
BOC fgen under
A+H
Generator frequency was under the Gen <f limit for Gen f
del time. Under frequency protection is based on Gener
protect: Gen <f and Gen f del setpoints.
20
BOC fgen over
A+H
Generator frequency was over the Gen >f limit for Gen f
del time. Over frequency protection is based on Gener
protect: Gen <f and Gen f del setpoints.
20
BOC ReversePwr
A+H
This alarm is issued by the reverse power protection. This
protection is based on Gener protect: Reverse power and
ReversePwr del setpoints. This alarm means that either
engine speed/power control does not work properly or
