Tyco Electronics Galaxy SC Controller J85501F-1
5 - 12 Acceptance Testing Issue 13 February 2001
Load share should be disabled (BGB1 SW100-5) anytime that rectifier
voltage is adjusted in these rectifiers with the Output CBs closed.
If an Intelligent controller is being tested, History for all tested alarms
can be reviewed under the front panel path: Main → History.
Terminate
Rectifier (TR)
Test
The TR test may be performed even if rectifier sequencing is not
planned to be utilized, as it provides a convenient means of testing that
the Galaxy SC recognizes all plant rectifiers and is able to control each
over their assigned ports.
One at a time, connect a test lead on the TB3 terminal block of the BJT
Termination board, from position 13 (ETRR / Ground) to position 8
(TR1), 9 (TR2), 10 (TR3), and 11 (TR4). The rectifiers will shut down
in groups as depicted below and remain off until the connection is
removed at which time they automatically restart.
TR1: G01, G02, G09, G10, G17, G18, G25, G26, G33,
G34, G41, G42, G49, G50, G57, G58
TR2: G03, G04, G11, G12, G19, G20, G27, G28, G35,
G36, G43, G44, G51, G52, G59, G60
TR3: G05, G06, G13, G14, G21, G22, G29, G30, G37,
G38, G45, G46, G53, G54, G61, G62
TR4: G07, G08, G15, G16, G23, G24, G31, G32, G39,
G40, G47, G48, G55, G56, G63, G64
Fuse Alarm
Tests
These procedures are used to test major amd minor fuse alarms.
Major Fuse Alarm Major Fuse Alarm may be tested by placing a blown fuse in the alarm
fuse position of any distribution fuse position in the plant or by inserting
a paper clip into the alarm indicating hole of its fuse holder. For
distribution circuit breakers, temporarily connect the pins 8 and 9 of any
KS22010 or KS22012 style circuit breakers) of any breaker together.
For GPS cabinets, fuse alarms may be simulated at the BNL1 or BNL7
alarm card by strapping FAJ on these cards to the hot bus (P4-1 for
BNL1, P5-6 for BNL7).
The DIST and MAJ LEDs and Power Major and MJF alarm relays will
be active. Alarms should be tested in each distribution bay of the plant
to verify the integrity of the alarm bus throughout the plant. If the
distribution bays are equipped with “Bay Fuse Alarm” indicating LEDs,
