H. Airstair Door Lockpin Sensor Adjustment
(1) Adjust forward airstair door lockpin sensor.
(a) Loosen screws (33, detail G, figure 501) on bracket (32) and move bracket so that it is 0.08 (± 0.02) inch from sensor (31) when lockpin (30) is in fully extended position. Tighten screws.
I. Standby Door Closed Warning Switch Adjustment
(1) Adjust forward airstair door closed switch.
(a) Loosen nuts (34, Detail H, Fig. 501) holding switch (37) in bracket (36) and adjust switch so that plunger (35) is depressed 0.11 (+ 0.00/- 0.04) inch when door is operated to door closed position. Tighten nuts, cycle door, and recheck plunger travel.
J. Aft Entry Door Sensor Adjustment
(1) Adjust aft entry door sensor.
(a) Loosen nuts (39, Detail I, Fig. 501) attaching sensor (40) to bracket (38) and move sensor so that gap between sensor and sensor actuator (41) is 0.08 (± 0.02) inch. Tighten nuts.

2. Door Warning System Test
A. General
(1) Door warning sensor and door warning circuit tests are described in the following paragraphs. The door sensor test checks that the sensors in the system are adjusted correctly, whereas, the circuit tests checks that each door warning circuit is operating correctly. The circuit test will not necessarily indicate the applicable sensor is adjusted within the limits specified.
B. Door Warning Sensors Test
(1)
General
(a)
The door warning sensor test is applicable to any sensor in the door warning system and should be performed after any door sensor is adjusted. Also, the applicable portion of the system test should be performed after the sensor test. The door sensor test can also be used as an isolation procedure during trouble shooting to confirm a sensor adjustment.

Equipment and Materials
(a) Door Proximity Sensor/Actuator Gap Test Set - F80165-42 consisting of F80165-2 chassis, F80165-19 cable, F80165-43 test box and spacers F80165-28, -29, -32 and -33.
(3)
Test Door Warning Sensor
(a)
Open DOOR WARNING DC circuit breaker on panel P6 and remove miscellaneous switching module from E3-2 electrical shelf.
(b)
Install F80165-2 chassis assembly in module position and connect adapter cable F80165-19 between chassis assembly and F80165-43 test box.
(c)
Close DOOR WARNING DC circuit breaker and turn switch on test box to ON.
(d)
Position selector switch on chassis assembly to applicable switch designation as referenced on door warning wiring diagram.
(e)
Turn dial on test box fully clockwise.
(f)
Open applicable door and place spacer assembly on sensor. Use F80165-28 spacer assembly for all doors except tire screen doors. Use F80165-32 spacer assembly for the right and left tire screen doors.
NOTE: The spacer assembly can be taped to sensor temporarily while testing sensor. The spacer assembly consists of an actuator slug and a spacer bonded together. The spacer side of the spacer assembly is placed against the sensor to be tested.
(g)
Turn dial on test box counterclockwise until the light on the box illuminates.
(h)
Remove the spacer assembly. The light shall extinguish.
(i)
Close and lock the door. The light shall not illuminate.
1) If light illuminates, it indicates the sensor is too close to actuator and should be readjusted.
(j)
Open door and place spacer assembly between slug and sensor. Use F80165-29 spacer assembly for all doors except tire screen doors. Use F80165-33 spacer assembly for right and left tire screen doors.
(k)
Turn dial on test box counterclockwise until light illuminates, then clockwise until light extinguishes.
(l)
Remove spacer assembly. The light shall remain extinguished.
(m)
Close and lock door. The light shall illuminate.
