HMC6 Power Management Controller User Manual
When the controller detects that the number of DG in
the network exceeds the limit when SG synchronizes,
SG & DG parallel number exceeds the limit and alarms.
When the controller detects that SG capacity is unable
to receive the total loads, SG capacity is insufficient to
output and an alarm is given.
When the controller detects that SG capacity is unable
to receive the total loads, DG & DG parallel number
exceeds the limit and alarms.
When the controller detects timeout of
grid-connection, it outputs and alarms.
When controller detects that there is no Close signal
after the Close delay has expired, it will initiate a trip
alarm.
When controller detects that there is no Open signal
after the Open delay has expired, it will initiate a trip
alarm.
When the controller detects that the main switch
abnormal trip input port is active, the controller
initiates an alarm signal.
When the controller is grid-connected in non-manual
mode, it detects that the feedback input port of
generation closing is inactive and the voltage, power
and current are both 0, then the controller initiates an
alarm signal.
When using BUS bar breaker, if the Bus bar breakdown
input is active of other controllers on bus tie, but the
current bus breakdown input is inactive, an alarm is
given.
When the SG mode is enabled and the input port is
configured with the shaft solenoid valve closing
feedback is effective, alarm will be given if the
feedback state of the shaft solenoid valve closing and
opening is inconsistent with that of the controller.
When controller detects the power supply voltage has
exceeded the set value, it will initiate a warning alarm.
