Abstract :
Door Warning System is a detection device to provide visual indication to the crew when doors are not locked (not latched). Door warning lights are located on the announciator panel on P5 overhead panel. The door warning light is controlled by proximity sensor in door area. When the sensor with the target has a distance or gap that does not match, the door warning lights will comes on even thought the door have been closed. To overcome this gap, do the test at PSEU to get the gap value. After testing at PSEU its followed by an adjustment in the sensor reverse to usual condition the optimum gap. Adjustment are made by monitoring the PSEU to get optimum gap. After adjustment on the sensor its followed by checking and restesting. The gap sensor is at a specified distance of 3,94 inches (0,100 m) with tolerance 0,79 inches (0,02 m) after troubleshooting. After the sensor gap on optimum position, door warning light is normally use. Door warning light comes off when the door is closed
