exceeds 57
C. For engine start limitations
see AOM 17, Power Plant.
EXT PWR AVAIL light (blue).
When light is on, external power is connected
and is available for use.
DC AMP/VOLT indicator.
Indicates the voltage for respective selected
bus or source. If L or R GEN selected the
indicator also shows current load in amperes.
NOTE: AMP is only indicated when L or R GEN
is selected.
DC AMP/VOLT selector.
Selects bus or source to be displayed on
DC AMP/VOLT indicator.
26V MAIN/STBY switch.
MAIN INV
−
Connects L and R INVERTER BUS
26 V AC to the main inverter.
STBY INV
−
Connects L and R INVERTER BUS
26 V AC to the standby inverter.
MAIN INV light (amber).
Comes on if the main inverter fails or the
MAIN INV 115/26V switch is in OFF position.
MAIN INV 115/26V switch.
In ON position the main inverter supplies 115V AC to
the L and R INVERTER BUS 115V AC.
It also supplies 26V AC to the L and R
INVERTER BUS 26V AC if the 26 V MAIN/STBY INV
switch is in MAIN position.
