Electrical System
Batteries
With the BAT 1 and BAT 2 switches in the on position, the bat-
tery relays close to direct battery power to the Battery Charging
bus. From the Battery Charging bus, power flows to the rest of
the electrical system through current limiters.
Ni-cad battery installations have a temperature monitoring sys-
tem consisting of BAT 140 and BAT 160 annunciators and a
battery temperature gage. If battery temperature reaches
140×F ( 6 0×C), the amber BAT 140 annunciator illuminates. If
battery temperature continues rising to 160×F (71×C), the red
BAT 160 annunciator illuminates.
Emergency Battery
Single or dual emergency ni-cad or lead-acid battery packs
provide 24V and 5V DC power for essential equipment (i.e.,
emergency gyro, lighting, etc). Depending on the module
installed, the battery pack’s module provides 24V DC, 115V
AC, and 26V AC power (DC to AC inverter module) or 24V and
5V DC (DC to DC converter module). The module used
depends on the electrical requirements of the equipment
requiring emergency power.
With the EMER PWR BAT switch(es) in the STBY position,
only the emergency gyro receives power. If there is a power
failure, placing the EMER PWR BAT switch(es) in the on posi-
tion supplies power to the emergency gyro, to landing gear
control and indication, and to flap control. Normally, with a fully
charged battery, emergency power is available for approxi-
mately 30 minutes.
