Operating procedures
2-9.1 Normal lighting
a.
ROWPU space. Close circuit breaker 2P13 on power panel 3 (Figure 2-5) to supply power to deck lighting
panel. Close circuit breakers 2P13-1 thru 2P13-4 on deck lighting panel (Figure 2-6) to supply power to
fluorescent lights in ROWPU space. Door interlocking switches (blackout switches) automatically turn lights
on when the port or starboard doors are closed and turn lights off when either door is opened. Red light stays
on when a door is opened.
b.
Dayroom. Close circuit breaker 2P13 on power panel 3 (Figure 2-5) to supply power to deck lighting panel.
Close circuit breaker 2P136 on deck lighting panel. Turn fluorescent lights ON in dayroom by operating
either of the rotary dayroom light switches located by starboard or aft door. Door interlocking switch
(blackout switch) automatically turns fluorescent lights ON when starboard door is closed and turns lights
OFF when door is opened. Red light stays ON when door is opened.
c.
Workshop. Close circuit breaker 2P13 on power panel 3 (Figure 2-5) to supply power to deck lighting panel.
Close circuit breaker 2P13-5 on deck lighting panel. Turn fluorescent lights ON in workshop by operating
rotary workshop light switch located by door to ROWPU space.
d.
Void. Close circuit breaker 3P 13 on power panel 3 (Figure 2-5) to supply power to void lighting panel.
Close circuit breakers 3P13-1 thru 3P13-8 on void lighting panel (Figure 2-7) to turn lights ON in voids.
2-9.2 Emergency lighting. If the normal power system fails, the emergency power system automatically keeps
emergency lights (white fluorescent and red incandescent) lit. As soon as the failure occurs, the 24 Vdc battery bank on
top of the deckhouse supplies power to the inverter. The inverter changes the 24 Vdc power to 120 Vac and supplies the
emergency panel.
A green (Barge 1 ) or blue (Barges 2 and 3) light on the switchboard indicates that emergency power from the 24
Vdc battery bank is available for emergency lighting In the event of power failure. When the circuit breakers listed below
are closed, emergency lights can be turned ON or OFF by activating any of the four ON/OFF toggle switches. One
switch is near the green (Barge 1) or blue (Barges 2 and 3) light, one near the dayroom starboard door, one near the
ROWPU space port door, and one near the ROWPU space starboard door.
a.
ROWPU space. ROWPU space white lights circuit breaker 1 OP1 3A-1 and ROWPU space red lights circuit
breaker 10P13A-3 on emergency lighting panel (Figure 2-8).
b.
Dayroom. Workshop, dayroom white lights circuit breaker 10P13A-2 and workshop, dayroom red lights
circuit breaker 10P13A-4 on emergency lighting panel.
c.
Workshop. Workshop, dayroom white lights circuit breaker 10P13A-2 and workshop, dayroom red lights
circuit breaker 10P13A-4 on emergency lighting panel.
d.
Voids. Voids 1 and 2 white lights circuit breaker 1 OP1 3A-5 and voids 3, 4, and 5 white lights circuit breaker
10P13A-6 on emergency lighting panel.
