4.5.2
Closing the shore connection breaker
Control Procedure
PMS control
When the operator closes the shore connection breaker, the power management system transfers the
load from the gensets to the shore connection. The shore connection must therefore be live and have
enough capacity to take over the genset load.
To close the shore connection breaker:
1. Operator action: Press to close the shore connection breaker.
a. System response: The power management system synchronises the busbar with the shore
connection. During synchronisation, the breaker LED is yellow (flashing).
b. System response: When the shore connection and busbar are synchronised, the controller closes
the breaker. When the breaker is closed, the breaker LED is green.
• If the shore connection and busbar are not synchronised before the synchronisation timer
expires, the breaker does not close. The synchronisation failure alarm is activated.
• If the shore connection does not have the capacity to take over the genset load, the controller
does not close the shore connection breaker, and displays an info message.
c. System response: After the shore connection breaker is closed, the power management system
automatically de-loads and opens the genset breakers of all the GENSET controllers that are in
AUTO mode. After the genset cooldown period, the power management system then automatically
stops the gensets of all the GENSET controllers that are in AUTO mode.
Switchboard
control
When the controller is under switchboard control, the display unit push-buttons are disabled. The shore
connection breaker can only be closed using the switchboard.
