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 Figure 3-1 for location of the BSL board.
Procedure
One at a time, connect a test lead on the BSL alarm interface terminal
block from position 76 (ETRR/Ground) to position 73 (TR1), 79 (TR2),
85 (TR3), and 80 (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
Note: This function can be performed by using EasyView.
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.
