Tyco Electronics Galaxy SC Controller J85501F-1
3 - 34 Installation Issue 13 February 2001
Controller Fusing Remove the BASIC, INTEL and PER MON fuses from the BJF
Fuse/Termination board located to the right of the Basic side circuit
packs, using the fuse puller provided. Insure that all other fuses on this
board are fully engaged. See Figure 3-2.
Power, Regulation,
and Shunt Inputs
1. Pass the terminal side of the leads on the provided Pigtail wire set
(comcode 847411824) through the hole in the right side of the
Galaxy enclosure and fasten them to the appropriate terminals of
TB1 on the BJF Fuse/Termination board. See Figure 3-2.
Note that for this MCS retrofit, a strap is provided in the controller
parts kit for use in tying DG and DG2 together between positions
5 and 6 of TB1, since only one DG lead will be available from the
input power connections for the MCS.
2. Verifying proper polarity, connect the power, regulation and shunt
leads (DB, DG, RB, RG, SH-, SH+) removed from MCS to the
butt splices of the Pigtail wire set at the rear of the Galaxy,
dressing and securing these leads as necessary.
3. Connect the power and regulation leads to the same bus bars they
were disconnected from. The DB lead may be fused at 10 amps
(comcode 847572732). Use this option if the power is not obtained
from the same bay in which the Galaxy is located. Again, verify
proper polarity when making these terminations.
4. Connect the shunt pair to the plant shunt, observing polarities as
indicated in Figure 3-3. Check voltage at TB1 as stated on page
3-6, item 4.
Reconnect Alarm
Wiring
Reconnect the alarm leads previously removed from MCS TB1 to the
BJT1 terminal block. Refer to Figures 3-5 and 3-6 and Table 3-I.
Optional Feature
Wiring
If any optional features are to be equipped on the Galaxy, complete their
external wiring in accordance with the Sections of this manual
referenced in Table 3-G.
Power Up Galaxy
Controller
1. Reinsert all Galaxy circuit packs except the BJA (and if equipped,
BJJ) Power board(s). Slide each pack along its guides into the
backplane and lock into place by lifting the circuit pack locking
lever to the full upright position.
