Three different T-Rs are avai!able for use with the generator set. T-k op;"rate from
the 400-Hz, 115-V AC genzrcrtor output and produce a DC output of 28.5-V, 35-V,
or 112-V depnding upon the T-K selected.
6. Canopy
A sheet rretal enclosure, identified as a canopy (1, Fig. l),provides protection fti the
engine, generator and electrical controls.
The canopy is designed to reduce the operational noise level in the immediate area of
the moo h ine .
Doors and panels are covered on the inside with Fiberglas acoustic material
to reduce rcf lekted and conducted noise, and to abscb noise.
Noise prodvc ing vibration
in most freqtient ly used doors on the left side is reduced by the use of two-point s Iani locks.
.
Less frequently used doors on the right side are equipp&d with screw-operated latch fasteners
which are tightened after latching to reduce vibration.
Insulating strip around all doors
also reduce noise. ktal strip. are mounted ho;izontaIly acras the front grille to deflect
.
engine fun exhaust air and noise upward.
Two large openings in the canopy top provide an entrance for cooling air and an access
to internal components. A hood-type cover is mounted about two inches above each open-
ing . The cover is flanged downward and extends beyond the edges of the upwardly flanged
opening to prevent entrance of blowing rain while still allowing a good flow of air. Air
enters the forward opening into the engine compartment and is discharged through the
radiator by the engine fan. Air enters the rear opening into the generator compartment.
It is then circulated over generator controls and drawn into the rear exciter and genera-
tor housings where it passes over all windings before king discharged by the generator
fan.
All generator sets in this Series except the tractor-mounted unit are equipped with a canopy
having dotis on both sides. Tractor-mounted units have two large removable panels on
the right side mainly because the right side of the machine is not accessible when mounted
on a tow tractor, and secondly because the thick doors would not allow mounting in the
limited space available on the tractor. Panel mounted instruments may be observed through
