NOTE
Use this chart in conjunction with the test fixture lamp indication table 8-11. Refer to the
appropriate test number below. Alongside the lamp number with the fault indication, find the
suspect circuit items that could be the cause (see fig. FO-19 fault/safety gate logic diagram).
Apply standard digital troubleshooting techniques to isolate the faulty component. The test
fixture lamps DS1 through DS10 represent the following alarm monitor fault and safety alert
functions:
a.
DS1: safety alert waveguide interlock indication.
b.
DS2: safety alert antenna elevation indication..
c.
DS3: RSS system fault indication.
d.
DS4: dc power indication.
e.
DS5: CSS temp indication.
f.
DS6: audible alarm signal.
g.
DS7: CSS system fault indication.
h.
DS8: PA 1 inhibit signal.
i.
DS9: PA 1 inhibit signal.
