SINGLE GENERATOR FAILURE
In the event of a single generator failure in
flight, the operating generator must supply
the load for both sides of the DC electrical
power system. To prevent shock loading of
the remaining generator, load shedding of the
non-essential busses automatically occurs.
After a 5 second voltage check delay, the bus-
tie automatically closes. The CAS will display
an amber “L or R GEN FAIL” message and a
white “BUS TIE CLSD” message after the
bus-tie automatically closes. Indications on the
electrical control panel would be illuminated
OFF captions on the left and right NON-ESS
bus switches, an illuminated OFF caption on
the GEN switch of the failed generator and an
illuminated bar on the BUS-TIE switch. This
is illustrated in Figure 2-23. All other sys-
tems will continue to operate normally. If nec-
essary, the crew should reduce the load further
in accordance with AFM procedures and if
conditions warrant, attempt to reset the failed
generator. Following AFM procedures, non-
essential busses may be regained by selecting
the appropriate NON-ESS switch. No aircraft
electrical system power is required to reset a
generator, however, the corresponding L GEN
or R GEN circuit breaker must be in to sustain
generator operation.
