The password is entered by pressing the correct se-
quence of numerical keys (the 0 key through the 9
key), then pressing the
key. As digits are entered,
asterisks will be placed in the password field. Once
entered, the menu system will compare the password
to a list of stored passwords. If the entered password
matches one of the stored passwords, the user is al-
lowed access at the specified level, and the display will
show the first applicable parameter of the menu list,
with the appropriate edit prompts. If the password is
not correct, the screen will display “Password Incor-
rect” for two seconds and then revert back to the Login
Prompt. Pressing the
key during password entry
will cancel the password entry process and take the
user back to the Login Prompt.
Once a password has been accepted, reentry of that
password will not be required until key activity is idle
for fifteen minutes. This ensures that the menu system
reverts to password protection within an acceptable
timeout.
NAVIGATION
The keypad allows complete control of the system
from a central location. The keypad offers a multitude
of commands available to access displays, program
parameters, and initiate system commands. The key-
pad consists of thirty-six keys, which are divided into
three categories, Data Entry, Navigation and Menu Se-
lection keys. A description of each of the keys is con-
tained below.
Data Entry Keys
The Data Entry Keys provide a means to enter val-
ues for items that support edits. The keys available to
support numeric input are the 0 through 9 keys, the
decimal key, the +/- key, the
key and the
key. The
keys available to support choice input are the
key,
the
key, the
key, and the
key.
Once editing has
started, the user must press either the
key or the
key
. Any other key press will result in the “
Press
or
to Exit
” message displayed for two seconds. If you
try to edit an item that is view only, it will be ignored
by the menu system.
When a numeric value that can be modified is dis-
played under the “Setpoints” menu key, the Default,
High, and Low prompt will be shown in the upper right
portion of the display. Pressing the +/- key, the decimal
key, or any of the 0 through 9 keys will activate the
edit mode and a request for the proper password will
be made. After the proper password is entered, the cur-
sor will be shown at the digit to be changed. After the
desired numeric value has been entered, press the
key to save the new value and exit the edit mode. Press-
ing the
key will fill in the default value. Edits will
only be accepted when followed by pressing the
key.
Pressing the
key while in the edit mode will cancel
the edit mode and leave the value unchanged. If an out
of range value is entered, the Default, High and Low
prompt is replaced by the “Out of Range” message for
two seconds.
When a choice value that can be modified is displayed
under the “Program” or “Options” menu key, the
prompt will be shown to the left of the present choice.
The
key or the
key will allow the different choic-
es to be viewed, and pressing either one will activate
the edit mode and a request for the proper password
will be made.
See Password section of this manual for
the proper procedure for entering the password.
When
the desired choice is displayed, press the
key to save
the new value and exit the edit mode
.
Pressing the
key while in the edit mode will cancel the edit mode
and leave the value unchanged.
Navigation Keys
The Navigation Keys provide a means to browse items
within a menu. The keys currently available to support
navigation are the Menu Select keys, the
key, the
key, the
key, and the
key.
Pressing a Menu Select key brings the user to the first
screen under that menu. The screens within each menu
are arranged in a circular list. The user may browse
through the screens using the
key and the
key.
Pressing the
key will advance through the screens
in order from top to bottom until the bottom screen has
been reached. When the bottom screen is displayed,
pressing the
key will wrap the display to the top
screen of the menu. Pressing the
key will move
through the screens in order from bottom to top until
the top screen has been reached. When top screen is
displayed, pressing the
key will wrap the display to
the bottom screen of the menu. Once either the
key
or the key
is pressed, pressing any Menu Select key
will bring the user to the first screen under that menu
(even if it is the same menu being viewed).
Navigation through the circular list of items can also be
achieved by repeated presses of the same Menu Select
key, as long as no other keys are pressed. For example,
pressing the UNIT DATA key three times will bring
the user to the third screen of the UNIT DATA menu;
pressing the UNIT DATA key once, then pressing the
