Explain the difference between the battery switch "ON" and the battery
switch "BATT EMERG" position.
ON = the #1 battery supplies voltage to both emergency contactors ;
EMERG = each battery supplies voltage to its respective emergency
contactor and the battery charge contactors are forced open.
What is the purpose of the BATTERY ISOLATE switch?
To isolate a single battery from its charging source.
What is the purpose of the BUS TIE?
To connect or isolate electrical power between the PS1 and PS2 buses.
For external starts, a ground power unit capable of supplying volts DC; a
short
term capability of _____ amps, and fitted with a amp current limiter must be
used.
28V; 1500A, 1100A
When charging the aircraft batteries off ground power, the EXT BATT
CHG switch should be selected off when the charge current drops to
less than ______________________________________________________ amps.
5A (NiCad batteries only)
The bus tie contactor will open when the voltage sensed on the PS1 bus bat
exceeds
_____ volts or drops below _ volts.
