 **ON A/C 301-399,
 Subtask 33-51-00-720-051-B
 D. Test of the forward and rear emergency-exit door switches of the
 emergency-exit escape-slide lighting.

 WARNING : BEFORE YOU START WORK ON THE DOOR, MAKE SURE THAT:
_______
 -
THE EMERGENCY CONTROL HANDLE IS IN THE DISARMED POSITION WITH THE SAFETY PIN INSTALLED.

 -
THE PERCUSSION LEVER OF THE DOOR-DAMPER AND EMERGENCY-OPERATION CYLINDER IS IN THE DISARMED POSITION WITH THE SAFETY PIN INSTALLED.

 WARNING : DO NOT OPEN THE EMERGENCY EXITS.
_______
 NOTE : Make sure that the EMER EXIT LT switch 4WL on the SIGNS panel 25VU
____ is in the OFF position. This test is for the forward RH/LH emergency-exit doors. For the rear RH/LH emergency-exit doors use the information in the brackets.

 (1) Do the test of the forward and rear emergency-exit door switches of the emergency-exit escape-slide lighting.
 -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the aircraft:
 -make sure that the related
 emergency-exit door is closed.

 2.
 In the cockpit, on the overhead circuit breaker panel 49VU: - open the circuit breakers,

 LIGHTING EMER LT CABIN, 1WL and
 2WL.

 3.
 In the cockpit, on the secondary circuit breaker panel 122VU: - open the circuit breaker, CABIN

 EMER LT, 3WL.

 4.
 In Zone 231 (251), on the emergency power-supply unit 15WL (11WL):

 -remove the electrical connector
 15WL-A (11WL-A).

 5.
 On the DGTL multimeter:

 -connect the positive test lead
 of the DGTL multimeter to pin C

 (S) of the connector 15WL-A
 (11WL-A),

 -connect the negative test lead
 of the DGTL multimeter to pin m
 of the connector 15WL-A
 (11WL-A).

 -set the DGTL multimeter to the
 kilo ohm range.

 NOTE : The closed circuit is in the kilo ohm range because the door switches
____
 are electronic types.

 6. On the forward (rear) left  In Zone 231 (251) on the DGTL emergency-exit door: multimeter:
 1EFF : 301-399, 1 33-51-00Page 556 1 1 Aug 01/05R 1 1 1CES 1

 -------------------------------------------------------------------------------
ACTION RESULT -------------------------------------------------------------------------------
-remove the safety pin from the control handle of the escape slide.
 -
set the slide control handle to the ARMED position.

-
set the slide control handle to the DISARMED position.

-install the safety pin in the control handle of the escape slide.
 7. On the DGTL multimeter:
 -connect the positive test lead of the DGTL multimeter to pin D
 (k) of the connector 15WL-A (11WL-A),
 -connect the negative test lead of the DGTL multimeter to pin m of the connector 15WL-A (11WL-A).
 8. On the forward (rear) left emergency-exit door:
 -lift the door handle approximately 10.0 mm (0.3937 in.), but do not open the emergency-exit door.
 -lock the door handle.
9. On the DGTL multimeter:
 -disconnect the testleads and remove the DGTL multimeter.
