 The roller guides are mounted on the rear edge member of the door structure. The guide fittings are installed at the door frame of the fuselage.
 The guide rollers engage the slots of the guide fittings when the door is in the closed position. Thus, the guide rollers put the door in the correct position during the door is lowered. The guide rollers are mounted on each edge members of the door structure. The guide fittings are installed at the door frame of the fuselage.

R R  To get access to the inboard handle, the operator must pull the handle cover from the inboard handle. When the inboard handle is moved from its 
R R R R R  LOCKED position, this operates the internal control shaft so that the locking shaft turns. Thus, the target lever moves away so that the target does not align to the proximity sensor. The proximity sensor then gives two different signals to warn the crew that the door is not correctly locked. 
R R R R  One signal is sent to the ECAM system so that the MASTER CAUTION LIGHT in the cockpit comes on. At the same time it gives a single chime warning for the flight crew. The other signal causes the white indicator light SLIDE ARMED to come on.
 When the inboard handle moves from the LOCKED to the UNLOCKED position, the subsequent occurs: - The drift pin retracts and the locking hook disengages from the lock fitting of the door frame. This releases the spring-loaded switch mechanism so that its target is not aligned with the related proximity switch. It sends a signal to the ECAM system to warn the flight crew that the door is in the UNLOCKED condition.
 - The indication window shows the red color UNLOCKED.
 - The cover mechanism lowers the guide arm cover of the door lining so that the guide arms come free. - The lifting shaft turns and lifts then the door until its guide rollers are clear from the fuselage guide fitting. The support arm holds the door in balance.
 When the door is lifted, the operation lever of the escape slide-release mechanism operates the release lever of the door damper and the emergency

In the door open sequence a short interruption of max. 10 seconds occurs before the door is fully opened to make sure that the related escape-slide is deployed. During the door movement the release lever of the escape-slide release mechanism operates the actuation lever on the door frame. Thus, the escape- slide control mechanism inflates the emergency escape-slide below the door.

 When the door moves in the forward direction, the guide arms keep the door parallel to the fuselage. The door buffer at the support arm stops the door travel when it touches the fuselage. Then, the latch of the door stay mechanism engages with the latch fitting mounted on the door frame and the door is locked in its fully open position.
 B. Opening of the Emergency Exit Door from the Passenger Compartment (DISARMED Mode)
 NOTE : In the subsequent description the emergency exit door is referred

 to as door.

 For the maintenance procedure only, the operator must open the apron cover to get access to the slide control handle. To set the escape-slide release mechanism to the disarmed condition, the operator must pull the slide control handle. In the indication window you can see the red color DISARMED.
 This operation turns the intermediate shaft so that the target on the combined lever does is no longer aligned with the proximity sensor. This gives a signal to the ECAM system to show that the door is in the disarmed condition. The connection rod transmits the rotation of the intermediate shaft to the release shaft which turns then. Thus, the release lever does not engage with the actuation lever on the door frame. This prevents the operation of the escape-slide control mechanism when the door is manually opened during maintenance. At the same time the operation lever is no longer engaged with the release lever of the door damper. This prevents its operation when the door is open.
 When the inboard handle is moved, this operates the internal control shaft so that the locking sshaft turns. Thus, the target lever moves away so that the target is no longer aligned to the proximity sensor. The proximity sensor then gives two different signals to warn the crew that the door is not correctly locked.
