View Active
Alarms Mode
If alarms are active in the system, the last two rows of the screen
will provide additional softkey information. The third row will
provide a softkey that allows a user to deactivate all audible
alarms. This is performed by using the “ACO” feature. The
fourth row on the display will provide immediate access to the
system alarms. This mode is entered by pressing the View
Active Alarms softkey. While in this mode, alarms are listed in
order of severity. All major alarms will be listed first, followed
by minor alarms. If four or more alarms are present, use the up
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 BUJ1 board is a hardware enable switch for
Configuration mode of the J85501M-1. 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
custom applications. The defaults are determined by SW1-2.
SW1-2 = 0 is standard, SW1-2 = 1 is custom. SW1-2 is
recognized only upon power-up of the GCM.
In addition, the other remaining switches on SW1 (see Figure 2-
5) are used to configure the installed option card, the installed
rectifier class, and alarm setting for alarm contacts
