It is always detected.
When this is enabled and the controller detects that the voltage
unbalanced value has exceeded the pre-set limit, it will initiate an alarm
signal.
It is always detected.
When controller detects that ground relay close failure, that is, breaker
close input is inactive after ground relay close outputs, and then it will
initiate an alarm signal.
It is detected when ground relay is closing.
When controller detects that ground relay open failure, that is, breaker
open input is inactive after ground relay open outputs, and then it will
initiate an alarm signal.
It is detected when ground relay is opening.
Table 11 Safety Trip and Stop Alarms
When this is enabled, and the controller detects that the genset speed
is above the pre-set limit, it will initiate an alarm signal.
It is always detected.
When this is enabled and the controller detects that the genset speed is
below the pre-set limit, it will initiate an alarm signal.
It is detected after "warming up" and before "stop idle".
When the controller detects the genset speed is 0, it shall issue an
alarm signal.
It is detected after "safety on time" before "ETS solenoid hold".
When this is enabled, and the controller detects the genset frequency is
above preset limit, it shall issue an alarm signal.
It is always detected.
When this is enabled, and the controller detects the frequency is below
the preset limit, it shall issue an alarm signal.
It is detected after "warming up" and before "stop idle".
When this is enabled, and the controller detects the genset voltage is
above preset limit, it shall issue an alarm signal.
It is always detected.
When this is enabled, and the controller detects the voltage is below the
preset limit, it shall issue an alarm signal.
It is detected after "warming up" and before "stop idle".
When this is enabled, and the controller detects the genset current is
above preset limit, it shall issue an alarm signal.
