Dc Electrical Controls - BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual

CONTROL AND MONITORING
A rotary selector on the DC metering portion
of the electrical control panel (Figure 2-25) al-
lows for the monitoring of voltage and load
conditions. Bus voltage is monitored on DC
bus 1, DC bus 2, and the DC essential buses.
TRU load is displayed in amps. The fifth con-
tact on the rotary selector allows for monitor-
ing of battery condition and is also the point at
which external DC power voltage is read. The
voltmeter scale is between 15 and 35 volts. The
current load is displayed on a loadmeter cali-
brated from 0 to 100 amps. A BUS OFF light
illuminates on the electrical control panel when
any of the four DC buses is unpowered.

Figure 2-26. BATTERY MASTER Switch
A BATTERY light on the overhead panel
(Figure 2-26) illuminates to indicate that bat-
tery power is not available for use by the bat-
tery bus, possibly due to one of the following
conditions:
• The BATTERY MASTER switch is in
the OFF position.
• The battery has failed.
Figure 2-27 shows the total electrical system
in simplified form and illustrates AC and DC
system interconnection.
Figures 2-28 through 2-34 show the circuit-
breaker panels and locations.
