Terminate Rectifier (TR) Test
Introduction 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 controller recognizes all plant rectifiers and is able to control each
over their assigned ports.
Refer to Figures 2-1 and 2-2 for the BJT board of the rear access SC
controller and to Figures 2-3 and 2-4 for the BLG board of the front
access SCF controller.
Test Procedure One at a time, connect a test lead on the TB3 terminal block of the BJT
(SC) or BLG (SCF) 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
TR2: G03, G04, G11, G12, G19, G20
TR3: G05, G06, G13, G14, G21, G22
TR4: G07, G08, G15, G16, G23, G24
Caution: When this test is performed on a live plant, it may cause a
battery discharge (BD) to occur. Ensure that the battery reserve is able
to support the plant load.
