Table 2-6: DC Power Application and Tests
Step Action
9 On the DC PDA), set the remaining circuit breakers to the ON position by pushing them in one at a
time in the following sequence:
1. PA (four circuit breakers, labeled 1A–1B through 3C–3D).
2. HEAT EXCHANGER (two circuit breakers)
3. ETIB
4. PILOT BEACON
5. OPTIONS
10
Confirm that the MAP AMP display continues to indicate between 20 and 60 amps during the initial
power application.
NOTE
No battery charging or heavy RF loading is present at this point.
11 If the frame is not equipped with the pilot beacon option, set the PILOT BEACON circuit breaker
to OFF.
Battery Charge Test (Connected Batteries)
Table 2-7 lists the step–by–step instructions for testing the battery
charging performance.
Table 2-7: Battery Charge Test (Connected Batteries)
Step Action
1 Close the battery shelf circuit breakers (NO TAG) for connected batteries only. This process should be
completed quickly to avoid individual battery strings drawing excess charge current
NOTE
If the batteries are sufficiently discharged, the battery circuit breakers may not engage individually
due to the surge current. If this condition occurs, disconnect the batteries from the 27Vdc bus by
setting the MAP power switch to OFF, and then engage all the connected battery circuit breakers.
The MAP power switch should then be turned ON.
2
Using the clamp–on DC current probe and DMM, measure the current in each of the battery string
connections to the battery bus bars. The charge current may initially be high but should quickly
reduce in a few minutes if the batteries have a typical new–battery charge level.
