To be used by maintenance personnel only. When pushed, resets the
associated BTR or APR. Switch has no effect when the electrical system is in
auto mode. Illuminates amber when a generator bus fault trips (and locks out)
the associated BTR or APR. Also illuminates when an ac tie bus fault trips
(and locks out) all of the BTRs.
2. GALLEY BUS 1/2/3 OFF Switch - amber
The GALLEY BUS switch is a momentary contact switch that inhibits the
galley transfer relays from being closed. .
This switch has no effect when system is in the auto mode. Switch has two
positions in the manual mode: OFF and reset/on. Switch position is controlled
internally by the electrical power control unit. The reset/on position initiates
a galley bus reset and allows galley transfer relays to close.
The switch illuminates amber when galley transfer relays are open or upon
receiving a trip signal from the galley load control unit.
