Pilot’s Operating Manual
APU GENERATOR (if APU installed)
The generator driven by the APU is rated at 28 VDC at 250 AMPS. When the APU is running, operating
the APU GEN switch, located on the APU control panel - vestibule panel inner face, to CLOSE and held
for 5 seconds causes the APU generator contactor to close. The electrical output of the APU is
connected to PS2 busbar and selecting the BUS TIE switch to CLOSE also connects the APU output
to PS1.
OVERVOLTAGE PROTECTION
The GCU overvoltage protection circuit operates when the generator terminal voltage rises above 32.5
VDC. This opens the generator field and signals the GLC to open, disconnecting the generator from its
busbar.
