DOOR WARNING SYSTEM - ADJUSTMENT/TEST
1.  Door Warning System Adjustment
A.  General
(1)  Adjustments for the door warning system are described in the following paragraphs of this section. Adjustment is accomplished by mechanically positioning individual sensors or switches. Adjustment of a sensor consists of moving the sensor closer or further from the sensor actuator to meet the specified gap requirements. On doors where microswitches are employed, adjustments consist of varying the amount of the projection of the switch plunger or plunger actuator arm. After adjustment of any sensor, perform the Door Warning Sensor Test (Ref par. 2.B).
B.  Forward and Aft Service Door Sensors Adjustment
(1)  Adjust forward and aft service door sensor (Detail A, Fig. 501).
(a)  
On airplanes with alternate sensor loosen nuts (4) attaching sensor (3) to bracket (1) and move sensor so that gap between sensor and sensor actuator (2) is 0.08 +0.02 inch. Tighten nuts.

(b)  
On airplanes with preferred sensor, loosen adjustment nut (62) securing actuator (61) to adjusting screw (63). Move actuator so that gap between sensor and actuator is as shown in Fig. 501. Tighten adjustment nut (62).

C.  Forward and Aft Cargo Compartment Door Sensor Adjustment
(1)  
Equipment and Materials

(a)  
Shim - 65-67304-3

(b)  
Shim - 65-67304-4

 

(2)  
Adjust forward and aft cargo compartment door sensor (Detail B, Fig. 501).

(a)  Use laminated shims if and as required between sensor and mounting bracket or bracket and fitting to meet gap requirements shown on Fig. 501. Remove laminations as required.

D.  Tire Burst Protector Screen Door Sensor Adjustment (Right and Left Doors) (If Installed)
(1)  Loosen bolts (16, Detail C, Fig. 501), attaching sensor support (15) to screen support (18) and position sensor (14) so that the gap between actuator (20) and the sensor is 0.12 +0.05/-0.05 inch (Section C-C). Tighten bolts.
E.  Forward Entry Door Sensor Adjustment
(1)  Adjust forward entry door sensor.
(a)  Loosen screws (25, Detail D, Fig. 501) attaching sensor (23) to bracket (24) and move sensor until gap between sensor and sensor actuator (22) is 0.08 + 0.02 inch. Tighten screws.
