or down arrows to scroll through the alarms. When no alarms are
present, the default screen will display No Active Alarms. To
exit View Active Alarms mode, press “Done” the Home key. If
no key is pressed for 3 minutes, the Vector returns to the default
screen automatically.
Configuration
All rectifiers must be numbered uniquely. Valid numbers for
rectifiers are 1 through 24. Refer to the appropriate sections of
the plant manuals for setting ID numbers. NP rectifier
numbering is managed through configuration in the shelf. For
additional information, consult the appropriate NP
documentation.
SW1 and Softkey Display Navigation in Configuration Mode
SW1-1 of the BLJ3 or BTJ2/BTJ3 board is a hardware enable
switch for Configuration mode of the Vector display. If
Configuration is not enabled, the user is only permitted to access
and view the configuration parameters, but may not change any
of them. To allow configuration changes, move SW1-1 to
position 0. Once configuration has been completed, it is a good
practice to disable (position 1) SW1-1 to prohibit someone from
mistakenly changing these parameters.
Configuration mode is entered by pressing the Home key to
display the menu selections. Press the appropriate softkey to
enter the Configuration mode. The first parameter of the
configuration menu will be displayed. Refer to Table 4-A for a
description of the parameters of the configuration menu. Note
that two columns of default values are shown, for standard and
Flexent applications. The defaults are determined by SW1-2.
SW1-2 = 0 is standard, SW1-2 = 1 is Flexent. SW1-2 is
recognized only upon power-up of the GCM.
In addition, the other remaining switches on SW1 (see Figures
2-6 and 2-7) are used to configure the installed option card, the
installed rectifier class, and alarm setting for alarm contacts
HV/2ACF/VLV. If no option card is installed, set S1-3 to the
factory default of “0”. This will allow local terminal access. The
GPS rectifier class includes all 596 and 595 series of serial
controlled rectifiers. NP rectifiers include NP2500, NP1500,
NP1200, and NP1300 with installed NPC1 GP serial
communication option cards. The alarm select switch, S1-5, can
be changed and recognized while the GCM is powered.
Similarly, S1-7 can be recognized while the GCM is powered
and setting this switch to “1” will manually force a PBT session
