Maintenance
See Section 3,
, before performing any maintenance and observe all
warnings
Under normal operation the switches in the FET Switch Adapter are energized and
will conduct the input signal from the MTA to the FAI module input circuitry.
Periodic maintenance of the FAI modules requires that the FET Switch Adapter
operate correctly, so it should be tested when the FAI module is removed from
service.
Figure 9–13 through Figure 9–16 show the FET Switch Adapter test setups.
