While harbour operation is activated, either by a digital input or a signal from CustomLogic, the operation overrides the EDG max.
parallel time. During harbour operation the emergency genset is treated as an ordinary genset with the first priority and all normal
GENSET controller protections.
During harbour operation, the EMERGENCY genset controller can be forced under switchboard control by alarms that force the
other controllers under switchboard control, or by the Power management > Force all controllers in section to SWBD control input. In
this case, the EMERGENCY genset controller stays under switchboard control, and does not automatically start the emergency
genset during a blackout.
Inputs and outputs
Assign the Harbour operation digital input under Configure > Input/output. Select the hardware module, then select the digital input
to configure.

If the emergency genset controller is in harbour operation and this input is
activated, then harbour operation is cancelled and the genset returns to normal
operation.
If the Operator confirms harbour operation parameter is Enabled, then after the
Harbour operation digital input is activated, this digital input has the same effect
as pressing the Reject soft key then OK on the display unit.
Note: This is a pulse function. If this digital input is continuously activated, it will
NOT prevent or stop harbour operation.
