 3.  Leading Edge Flap and Slat Position Indication Module_____________________________________________________
 A.  A leading edge flap and slat position indication module controls the operation of the position indicating system (Fig. 2). The module consists primarily of plug-in switch and logic cards in the LE DEVICES annunciator panel light circuits, additional transistor circuits that work with the plug-in cards to control the pilots' indicating lights, and interconnecting circuitry. The module receives 28-volt ac power from the 28-volt ac transfer bus and 28-volt dc power from the No. 1 dc bus and provides a reduced dc voltage to the proximity sensor coils. The module is located on equipment rack shelf E3-2.
