Lamp return passes to external system equipment through connector
pins A1P1-9 and J8-Z.
d. Power Distribution. The countermeasures control receives +5
Separate circuits distribute the inputs
and +28 V dc power inputs.
The +5 V dc input at connector pin J6-V (figure FO-2,
sheet 1) passes through connector pin XA3-1 to the
The +28 V dc mission power at connector pins J3-F, J3-G,
and J3-Y (figure FO-2, sheet 2) passes to terminal studs
E1 and E3. Mission power is distributed to indicator CCA
A3, power transistor Q1 (figure FO-2, sheet 1), relay
TB2K1, and voltage regulator A1.
Through-wiring connections pass the +28 V dc mission
(ARC-186(V)) and (KY-58) inputs at connector pins J8-A
thru J8-D to external system equipment at connector pins
J7-a, J7-b, J7-Y, and J7-Z.
The +28 V dc ICS power input at connector pin J7-R passes
ICS power return
through filter FL1 to terminal stud E4.
at connector pin J7-S passes to terminal studs E5 and E7.
Filtered ICS power is distributed to diodes TB1CR3 thru
TB1CR5 and to external system equipment at connect pins
ICS power return is also
J8-b, J8-c, J3-H, and J3-J.
distributed to external equipment at connector pins J7-D,
J2-T, J2-W, J2-d, and J2-e.
