ANNUNCIATOR LIGHT TEST AND DIMMING - DESCRIPTION AND OPERATION
______________________________________________________________
1. General
_______ R R Bulbs supplied with 5VAC-400Hz are used for the lighting of the sun readable R lights in the cockpit. The current is delivered by the 115V/5V transformers. R Each light is parted in two sections ; each one has two 5V bulbs. R An annunciator light test switch permits illumination of all annunciators R and therefore check of all lights.

3. System Description__________________
R
R (Ref. Fig. 003)
R Miniature lamps (115 mA, 5VAC) are used for the lighting of the annunciator
R lights mounted on the panels and instruments in the cockpit.
R A relay (system) or internal contacts (case of ON-OFF position indication
R pushbutton switches) control illumination of each annunciator light. Four
R different busbars:
R - AC1 supply: 103XP
R - AC2 supply: 202XP
R - 115VAC STAT INV BUS: 901XP
R - Essential supply: 801XP
R supply the annunciator lights with 5VAC-400Hz through the transformers. In
R the case of emergency supply only busbar 901XP is serviceable.
R The system comprises:
A. Four Identical Transformers
Each one is supplied with 115V-400Hz.
Each one is connected to a different busbar.
They supply 5VAC-400Hz for the annunciator lights installed on the
overhead panel and on instrument panel and 6.3V voltage (full wave
