HMC6 Power Management Controller User Manual
When genset voltage has fallen below than the set
value 3, it will initiate a trip alarm.
When controller detects the reverse phase, it will
initiate a trip alarm.
The controller does not detect synchronization signal
within the pre-set synchronization time, it will initiate a
warning alarm.
When controller detects negative reactive power is
greater than set value, it will initiate a trip alarm.
When controller detects that the engine fault signal is
active, it will initiate a trip alarm.
After the feedback function is selected and the system
has started, if the voltage and frequency have reached
the requirements but the feedback input is deactivate,
it will initiate a warning alarm.
Start the system, if the voltage and frequency have not
reached the requirements after the on-load stable
delay has expired, it will initiate a block alarm.
Alarm when rate of change is greater than set value
When controller detects the generator current has
exceeded the set value 1, it will initiate a warning
alarm.
When controller detects the generator current has
exceeded the set value 2, it will initiate a trip alarm.
When controller detects the generator current has
exceeded the set value 3, it will initiate a trip alarm.
When controller detects the generator current has
exceeded the set value 4, it will initiate a trip alarm.
When the controller detects that negative phase
current has exceeded the set value, it will initiate a
warning alarm.
