Table 2-11: Apply AC Power to BTS Frame
Step Action
7
Set the MAP power switch to ON.
– The MAP VOLT display should read 27.4 +
0.2 VDC with the TCP switch set to OFF.
! CAUTION
Once power is applied to the MAP, be careful not to short either of the VOLT TEST POINTS to
ground. Failure to comply will result in severe damage to the MAP.
8
On the MAP, set the TCP switch (Figure 2-5) to ON.
– Verify no alarm LEDs are lighted on the MAP.
NOTE
Depending on battery compartment temperature, the rectifier voltage displayed on the MAP VOLT
indicator may change by as much as +
1.5 V when the TCP is set to on.
9 Check the rectifier current bar graph displays (green LED display on the rectifier module).
– None should be lighted at this time.
10
If batteries are fitted, set the ACLC HEATER circuit breaker to ON.
NOTE
The GFCI AC circuit breaker should remain OFF unless the GFCI outlet is in use.
Apply DC Power
Refer to Figure 2-4 and follow the procedure in Table 2-12 to apply DC
power to a BTS frame.
Table 2-12: Apply DC Power to BTS Frame
Step Action
1 Be sure all DC PDA and battery shelf circuit breakers are OFF (pulled out).
2 If it has not already been done, apply AC power to the frame by following the procedure in
Table 2-11.
3 Close (push in) DC PDA MAIN BREAKER.
4 On the DC PDA(Figure 2-4), set the PS1 and PS2 circuit breakers to the ON position by pushing
them in one at a time while observing the rectifier output current indicated on the MAP AMP display.
– The display should indicate between 20 and 60 amps.
5 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. (If Pilot Beacon option is installed) PILOT BEACON
