7.3 LOAD MANAGEMENT OPERATION, cont.
7.3.3 Voltage Droop
Upon Shore Alarm, the Voltage Droop feature may be used to save up to 10% converter capacity by
reducing the converter output voltage up to 5%. This is offered as a solution where the yacht does
not already have power management and load-shed capabilities that can be triggered with the Shore
Cord Alarm signal. A recovery time is provided so that the system does not alarm and droop in an
oscillatory manner as the load level moves above and below the alarm threshold. 30 minutes is the
default setting and can be adjusted as appropriate to the yacht’s conditions. This recovery time is the
time the droop will remain in place, regardless of alarm or load level, until returning to the nominal
converter output voltage. Voltage Droop will take precedence over Programmable Output Voltage
settings if used.
From the front panel, press the SHORE POWER + F2 buttons, and then Droop (F2) to access the
following screen:
Press the F1 or F2 buttons to adjust the DROOP %, DROOP enable, and Recovery settings; Forward
(F3) to advance the cursor through the three settings; Back (F4) to return the cursor through the
three settings, and Exit (F5) to save the settings and exit the screen. When the cursor is on the
DROOP % or Recovery settings, the F1/F2 buttons will read More/Less. When the cursor is on the
DROOP enable setting, the F1/F2 buttons will read Enable/Disable.
Default Range Units
