 The proximity switches detect :
 -
the position of the control handle of the passenger/crew doors,

 -
the position of the flap of the emergency exits,

 -
the armed or disarmed state of the escape slides of the passenger/crew

 doors and emergency exits. The Emergency Power Supply Units (EPSU) 13WL supply these proximity switches 17WV1(2) with 6VDC. The battery bus bar 301PP or the hot bus bar 702PP will directly supply the proximity switches 17WV1(2) with 28VDC:
 -when the EPSU 13WL cannot supply them with 6VDC, - or in the conditions that follow: -------------------------------------------------------------------------------AIRCRAFT DC POWER | AIRCRAFT AC POWER | EMER EXIT LT SW 4WL | EPSU PIN
 -------------------------------------------------------------------------------OFF | OFF | OFF | NO ON | ON/OFF | OFF | NO ON | ON | ARM | NO
 -------------------------------------------------------------------------------
NOTE : The bus bar 101PP supplies the proximity switches which detect the
____
 position of the locking hook of the passenger/crew doors.
