Information on binary
output available (See
list of Binary outputs)
BOC Gen Lx <V
(where x=1,2,3)
given by Gen <V BOC and Gen >V Sd
setpoints.
The generator voltage is unbalanced
more than the value of Volt Unbal
BOC setpoint.
The generator frequency is out of
limits given by Gen >Freq BOC and
Gen <Freq BOC setpoints.
Genset voltage phases are not wired
correctly. MCB closing is prohibited by
controller.
The generator current is unbalanced.
Generator current exceeds the limit
for IDMT protection given by Nominal
current and Amps IDMT Del setpoints.
The load is greater than the value
given by Overload BOC setpoint.
Generator current is higher than the
value given by Short Crct BOC
setpoint.
This alarm is activated when Earth
Fault value exceeds Earth Fault Sd
limit for at least Earth Fault Del period.
The protection comes active if the
speed is greater than Overspeed
setpoint.
During starting of the engine when the
RPM reach the value of Starting RPM
setpoint the starter is switched off and
the speed of the engine can drop
under Starting RPM again. Then the
Underspeed protection becomes
active. Protection evaluation starts 5
seconds after reaching StartingRPM.
Mains Lx >V
Mains Lx <V
(where x=1,2,3)
The mains voltage is out of limits
given by Mains <V and Mains >V
setpoints.
The mains voltage is unbalanced
more than the value of Mains VUnbal
setpoint.
The mains frequency is out of limits
given by Mains >Freq and Mains
<Freq setpoints.
Mains voltage phases are not wired
correctly. MCB closing is prohibited by
controller.
AMF controller in MRS mode detects
a voltage on mains connector.
If the input Emergency Stop is opened
shutdown is immediately activated.
The protection is active if the output
Sd Override is closed.
Failure of generator circuit breaker.
Failure of mains circuit breaker.
Failure of magnetic pick-up sensor for
