MULTI-CABINET OPERATION
Multi-cabinet systems are operated from the Master’s control panel. Each cabinet retains its own
control panel and metering display for individual monitoring.
Apply shore power to both cabinets and turn the disconnect switch
(14)
on each cabinet to the on
position. Within 1-3 seconds each cabinet will start, fans will be heard, and the display will
become active. Using the SHORE POWER
(2)
button on each cabinet, verify the applied shore
power measures the expected form. Use the Figure 7, Front Panel Controls on page 25 for button
references.
Press the SHORE POWER ON
(7)
button on the Master cabinet, bringing the Master and Slave
cabinets to the standby state. The green shore power LED
(7A)
on the Master and Slave cabinets
should now be lit. Measure the voltage being produced by the system by pressing the
CONVERTER POWER
(4)
buttons on the Master and Slave cabinets: they should indicate the
desired form and be within 5% of each other.
When ready to place the converter onto the ship’s distribution system, press the CONVERTER
POWER ON
(8)
button on the Master cabinet. This will close the output contactors of both the
Master and Slave cabinets simultaneously. The green LED
(8A)
should light on the Master and
Slave cabinets. With the ship’s loads now supplied by the converter, measure the load power
being supplied by each cabinet to ensure compliance to the system ratings. The system status
display will indicate a summary load percentage, based upon a worst case measurement of all
parameters.
If the system is equipped with the Seamless Transfer option, press the SHIP’S POWER -
CONVERTER
(9)
button on the Master cabinet to transfer power from the generator to the
converter. The system will operate as per the description in Section 6.1.2.
