supplied by when the Constant Speed Motor/Generator
is on line?
A - The CSM/G PMG.
B - Battery 2.
C - The DC BAT BUS.
What does the CSM/G control unit control when a
fault has been detected?
A - The solenoid control valve, the exciter
field and the GLC to off.
B - The exciter field to on, the GLC to off
and the generator speed to low speed.
C - The solenoid control valve to off, the
GLC to on, the exciter field to off.

TEST PUSHBUTTON PRESSED-IN
NOTE: the blue hydraulic system must be pressurized,
AC BUS 1 and 2 must be supplied.
When the EMER GEN TEST pushbutton is pressed in, a
loss of AC BUS 1 and AC BUS 2 and a speed higher than
100 knots are simulated by energizing relay 16XE.Relay
3PH is then energized, allowing relay 20XE to be
energized via relays 17XE and 18XE. The Constant Speed
Motor/Generator (CSM/G) CONTROL circuit is then
supplied from HOT BUS 703PP. This permits the VALVE
CONTROL circuit and the SOLENOID CONTROL VALVE to be
supplied from BAT2. DC ESS SHED BUS supply is
interrupted by relay 21XE.
Relay 22XE closes after the time delay and cuts the
CSM/G CONTROL circuit supply from HOT BUS 703PP. The
SOLENOID CONTROL VALVE supply is then transfered from
BAT2 to the PMG through the VALVE CONTROL circuit.
NOTE: RAT extension is inhibited by relay 30XE if 23XE
is released before 22XE closes.

When the EMER GEN TEST pushbutton is released out,
relay 16XE is de-energized. Relay 3PH is then
de-energized, allowing the LGCIU1 signal to stop the
CSM/G.
