Description
___________ (Ref. Fig. 002) The wing and engine scan light system has two lights 3LX and 4LX with a fixed single filament. The lights are installed one on each side in the forward fuselage of the aircraft. An attached transformer gives the rated operation voltage to each light. Electrical power comes from the 115 VAC busbars 202XP and 103XP through the circuit breakers 1LX and 5LX.
4.
Operation
_________
(Ref. Fig. 002)
The switch 2LX is supplied with 115 VAC when:
-
the busbars 202XP and 103XP are energized,
-
the circuit breakers 1LX and 5LX are closed.
The wing and engine scan lights come on when the switch 2LX is in the ON
position.
