“Roil-Out” Fea;urc
(TGW Tracts-Evlo:Jnted Unit)
Th:: s;cnerator set is supp!icd With two-channel-like tracks(JT,Fig. J) which arc
floor mounted in the gc!neraIor Ccrtmp~r’rmCnt of ths tC:v tractor.
Tracks arc cquippzd
with cam-follower, ne:;-die-bearing rollers which support the generator set ur+rlj al-
low it to roli in-and-au,
+ easily for servicing and maintenance.
Additiona! rollers
are mounkd on each
side of iho generator set main frame,
near the rear, to add
stability and to p;-cvet!t- the unit from tipping downward at ihe front when it is
rolled outward for service.
The set is secured in mounted position by two retaining bra&is attached at the front
of the unit (see 2-J, Fig. 2). The removal of twoscrews from the brackets allows the
set to be rolled out approximately38 inches,
wh.ere a stop-bar on the main frame
contacts a stop-block in the left track to prevent further outwardtravel.
B.
Protective Monitor
Asingle, solid-state device (4, Fig. JO) receives signals from a]1 of the fault sensing
units in t-he generator output circuit and functions to cause the load to be disconnected
from the generator if an abnormal ccndition of voltage, frequency, or load develops.
C. Pull-cut Trays
.
The control box is equipped with pul!-out, drawer-type trays (Fig. 8)
which provide ‘easy access to controls and equipment mounted in them. Each t&y
*
may be removed as an assembly bydi:;connecting a single quick-disconnect connector
and tripping. two safety latches.
D. Voltage Regulator
A solid-state, adjustable voltage regulator (Fig.
12) provides automatic voltage regula-
tion at the aircraft (or distribution panel when applicable). The regulator is also ad-
justable for a variety of output cable sizes and lengths.
E. Test Circuitry
A receptacle connector (Jo, Fig l
JJ) with wiring to various test points throughout the
electrical circuitry is provided for the attachment of a test box manufactured by Hobart
Brothers.
This test circuitry allows electricians to perform as many as twenty-four tests
and che,cks from one location, conveniently and easily.
F. Electric Governor
The engine is equipped with an all electric type governor kit (9, 17, and 20,
Fig. 3) and other speciai equipment more fully described under the engine description.
