Generator Trip Levels - BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual

The CSD oil also acts as a cooling agent for
the CSD and the generator. The oil is cooled
in a heat exchanger located on the engine
pylon service assembly. A sight glass on the
CSD allows for oil quantity checking. An oil
filter with a pop-out indicator button is pro-
vided to signal the need for a filter change. A
magnetic chip detection device is incorpo-
rated into the CSD drain plug.

Generator
The AC generator is a 30-kilovolt-amp (kva),
115-/200-volt, 3-phase, 400-Hz, brushless al-
ternator that is lubricated, cooled, and driven
by the CSD.

Generator Control Unit (GCU)
Each generator has its own generator control
unit to monitor, regulate, and control genera-
tor output. In conjunction with the other
GCU's, circuit protection and switching is
provided for the generator line contactors and
the generator transfer contactors.
The GCU will turn off the generator output if any
of the trip levels listed in Table 2-1 are exceeded.
Generator Line Contactor (GLC)
Each generator line contactor is responsible for
supplying its own main bus with power from:
• Its own generator through a generator
line contact; or
• A secondary source through a trans-
fer contactor
The secondary source is used only when the pri-
mary is unavailable. If power is not available
at either contact, the main bus is not powered
and the appropriate MAIN BUS OFF light on
the electrical control panel illuminates.
Generator Transfer Contactor
(GTC)
The GTC operates to supply power to the GLC
on demand. The priority of its sources are: (1)
the APU generator and (2) the opposite IDG.
