HGM9510N/HGM9530N Paralleled Genset Controller User Manual
When the controller detects that the mains frequency is above the
pre-set value, it will initiate a warning alarm.
It is detected after "Mains Parallel Mode" is active and after "Gen
closed".
When the controller detects the mains frequency has fallen below the
pre-set value, it will initiate a warning alarm.
It is detected after "Mains Parallel Mode" is active and after "Gen
closed".
When the controller detects that the mains voltage has exceeded the
pre-set value, it will initiate a warning alarm.
It is detected after "Mains Parallel Mode" is active and after "Gen
closed".
When the controller detects that the mains voltage has fallen below the
pre-set value, it will initiate a warning alarm.
It is detected after "Mains Parallel Mode" is active and after "Gen
closed".
When the controller detects mains ROCOF is above the pre-set value, it
will initiate a warning alarm.
It is detected after "Mains Parallel Mode" is active and after "Gen
closed".
When the controller detects mains voltage vector shift is above the
pre-set value, it will initiate a warning alarm.
It is detected after "Mains Parallel Mode" is active and after "Gen
closed".
When the controller detects the generator frequency and busbar
frequency is above 8Hz, it will initiate a warning alarm.
It is detected during synchronous close.
When the controller detects the number of the parallel gensets is
smaller than the set minimum parallel number, it will initiate a warning
alarm. There are 2 possible reasons: a) the communication wire
between the controllers is detached, leading to communication
interrupt. b) controller of parallel gensets is not powered on.
It is always detected.
When this is enabled and countdown time is 0, it will initiate a warning
alarm.
It is detected when the genset is running.
When the controller detects there is data losing of other gensets in
MSC1 bus, it will initiate a warning alarm.
It is always detected.
When the controller detects there is data losing of other gensets in
MSC2 bus, it will initiate a warning alarm.
It is always detected.
When the digital input port is set users-defined and if it is active, the
