Front-Panel Interface
Pushbuttons
enter the password for the higher access level, you remain at that access level
only until the front panel times out from inactivity or you
EXIT from the
specific command. When you EXIT the command, the front panel returns to
Access Level 1.
If the password jumper, JMP6A, is installed, there is no password protection,
and you will not be prompted for a password. If a particular level password
has been disabled with serial port command
PAS n DISABLE <Enter> , you
will not be prompted for a password.
When prompted for a password, enter the BAC or 2AC password, depending
on the requirements of the command. All commands are available using the
2AC password. The front-panel request for password shows a display of six
characters, shown initially as ABCDEF, with the A underscored. Use the up/
down arrow keys to scroll and set the first character of the password.
Passwords are case sensitive; be sure you use upper -or lowercase letters as
needed. Use the right arrow key to move to the second character, and adjust it
using the up/down arrows as before. Continue this process until
all six
characters are filled. If the password has fewer than six characters, fill the
remaining slots with a “blank,” found between the numeral 9 and the lower
case “a” in the character scroll. When the password is complete, push
{SELECT}
to enter it. If the password is correct, the relay will change to the higher level
and permit you to perform that level’s commands. If it is incorrect, the relay
will declare an
Invalid Password
, and allow another attempt. After three
incorrect attempts, the relay will pulse the
ALARM
contact for one second and
the front panel will exit the command you are trying to access.
Pushbuttons
Eight multifunction pushbuttons control the front-panel display. The button
legend defines the primary function in the top row and the secondary function
in the bottom row. The primary functions are for command selection, and the
secondary functions are for cursor movements and specific commands within
dialogues. The eight pushbutton primary functions will be discussed in the
order in which they appear from left to right on the front panel.
Primary Function
Review
TARGET RESET / LAMP TEST
The left-most button is dedicated to the
{TARGET RESET}
function. Except while
viewing or editing settings, pressing
{TARGET RESET}
causes the front-panel
LEDs to illuminate for a two-second lamp test and then clears all target LEDs
except for the
EN LED, which is illuminated if the relay is enabled. While
viewing or editing settings, the
{TARGET RESET}
button acts as a Help function,
showing specific information about the displayed setting.
METER
The
{METER}
pushbutton performs all of the MET serial port commands, via a
multilevel menu structure. The METER display is updated every two seconds.
While within the METER menu structure, the {CANCEL} pushbutton will take
the user back to the previous menu. The {EXIT} pushbutton will take the user
out of METER and back to the default display.
