Tyco Electronics Galaxy SC Controller J85501F-1
3 - 24 Installation Issue 13 February 2001
b. Check for battery voltage between terminals 5 and 8. Terminal
8 must be negative with respect to terminal 5 for negative plants
or terminal 8 must be positive with respect to terminal 5 for
positive plants.
c. Check for continuity between terminals 5 and 6 and continuity
between terminals 1 and 2.
3. Power up all rectifiers in the plant and adjust them to the selected
float voltage, reinstalling the regulation fuses removed in Step 1b.
Refer to the appropriate Rectifier Product Manual for the proper
procedure necessary to bring a rectifier on line.
Power Up the
Controller
1. Reinsert all Galaxy SC 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.
2. Reinsert the BJA (and if equipped, BJJ) Power board(s) into the
backplane of the Galaxy SC and lock into place by lifting the
circuit pack locking lever to its full upright position.
3. Reinsert the BASIC, INTEL, and PER MON fuses into their
positions in the BJF board. See Figure 3-2.
4. After a brief delay (up to 1 minute), all green LEDs on all circuit
packs should be active. Close the front cover and observe the
default display on the controller. A number of alarms and/or
warnings may be active at this point, along with the plant voltage
and load display. The plant load will remain at 0A until the plant
shunt is configured and distribution circuits are closed.
Galaxy SC
Configuration
Complete Galaxy SC’s initial configuration in accordance with Section
4.
Rectifier VI Circuit
Adjustment
Each Tyco Electronics ferroresonant rectifier reports its current output
to Galaxy SC through a “VI” (Voltage Proportional to Load) circuit
located on its control board. The accuracy of this circuit is essential for
proper operation of Galaxy SC’s Energy Management feature and to
eliminate nuisance “Rectifier/Plant Drain Inconsistency” alarms or
warnings. Check and adjust the VI circuit of each Tyco Electronics
ferroresonant rectifier in accordance with the appropriate Rectifier
Product Manual.
