400W Series Installation Manual Page 4-19190-00356-02 Rev. G4.8.2.4 FlagPin Name Connector Pin I/OVOR/LOC +FLAG P4006 3 OutVOR/LOC -FLAG (VOR/LOC COMMON) P4006 4 OutGLIDESLOPE +FLAG P4006 30 OutGLIDESLOPE +DOWN/-FLAG (GLIDESLOPECOMMON)P4006 31 OutThe Flag output is capable of driving up to three 1000 Ω meter loads. When valid information is present(Flag OUT OF VIEW) the Flag output is 375 ±80 mVDC. When invalid information is present (Flag INVIEW) the Flag output is 0 ±25 mVDC.4.8.2.5 OBSPin Name Connector Pin I/OVOR OBS ROTOR C P4006 9 OutVOR OBS ROTOR H (GROUND) P4006 10 OutVOR OBS STATOR D P4006 13 InVOR OBS STATOR F P4006 12 InVOR OBS STATOR E/G (VOR/LOCCOMMON)P4006 11 OutVOR OBS ROTOR C and H are a buffered 500 Hz output that is intended to drive the OBS rotors. VOROBS STATOR D and VOR OBS STATOR F are each phase and amplitude shifted version of the VORROTOR C output. Each pair is intended to read one of the two windings of the indicator’s OBS stator.4.8.2.6 VOR/LOC COMPOSITEPin Name Connector Pin I/OVOR/LOC COMPOSITE OUT P4006 8 OutWith a Standard VOR Test Signal applied, VOR/LOC COMPOSITE OUT is 0.5 ±0.1 VRMS into a 10kΩ load. With a Standard Localizer Centering Test Signal applied, VOR/LOC COMPOSITE OUT is0.350 ±0.05 VRMS into a 10 kΩ load.4.8.2.7 ILS ENERGIZEPin Name Connector Pin I/OILS ENERGIZE P4006 29 OutThe driver output voltage is not more than 1.0 V when sinking 20 mA. The maximum off state leakagecurrent with respect to GND is less than 10 μA.4.8.3 VOR/ILS Indicator ConfigurationNone.4.8.4 VOR/ILS Indicator Calibration and CheckoutRefer to Sections 5.3.14 and 5.3.15 for the VOR/LOC/GS checkout.4.8.5 VOR/ILS Indicator InterconnectRefer to Figure H-20 for the VOR/ILS indicator interconnect.
