3.2.3 DATA ENTRY
The Data Entry keys allow the operator to enter specific data into an active field. Data is
entered by using the numeric keypad and pressing “ENTER”, or by using the up and
down arrows to scroll until the desired setting is displayed and then pressing the
“ENTER” key. If using the arrow keys to change attenuation, slope or gain equalization
settings, the “ENTER” key need not be pressed. If using the numeric keypad to change
attenuation, slope or gain equalization the “ENTER” key must be pressed. Once a data
entry has been initiated with the numeric entry keys the up and down arrows can be
used to change the sign where applicable. Invalid entries will be ignored and cause an
error tone to sound. Any data entry not terminated by pressing the “ENTER” key will
expire after ten seconds, an error tone will sound, and the display will be restored to its
prior setting.
To change a setting while in local mode:
•
Use the up and down arrows to navigate until the desired screen appears on the
display.
•
Press the left or right arrow to change the cursor to a “right arrow” character “
→
”
•
If not already selected, select the desired data field by pressing the left or right arrow
keys until the desired data field is to the immediate right of the cursor. Data can
now be entered.
•
Enter the desired data using either the numeric entry keys or the up and down
arrows. Note that while the cursor appears as a “
→
” the up and down arrow keys
are used for data entry as opposed to screen navigation.
•
If necessary, press the “ENTER” key to accept the data entry.
3.2.4 REDUNDANCY CHAIN STATUS SCREEN
The Redundancy Chain Status screen is the default context of the display. These
settings appear at power-up. After one minute of idle time the display will default to the
Redundancy Chain Status screen. Repeated presses of the “STATUS” button will toggle
the display between the Status screen and the Redundancy Chain Status screen.
The fields in the Redundancy Chain Status screen provide overall status of the
redundancy chain including the status of the converters and switch modules in the
redundancy chain. The upper row of the display indicates redundancy chain position
and the state of the converters. The lower row of the display shows the transfer switch
position and status of the individual Switch Modules. The individual settings and NSU-
Converter Serial Link options of each converter can be accessed from this screen.
