Table 1 — Unit Sizes
Conventions Used in This Manual — The follow-
ing conventions for discussing configuration points for the
local display (scrolling marquee or Navigator™ accessory)
will be used in this manual.
Point names will be written with the mode name first, then
any sub-modes, then the point name, each separated by an
arrow symbol (. Names will also be shown in bold
and italics. As an example, the Lead/Lag Circuit Select Point,
which is located in the Configuration mode, Option sub-mode,
would be written as Configuration OPTNLLCS.
This path name will show the user how to navigate through
the local display to reach the desired configuration. The user
would scroll through the modes and sub-modes using the
and keys. The arrow symbol in the path name repre-
sents pressing to move into the next level of the
menu structure.
When a value is included as part of the path name, it will be
shown at the end of the path name after an equals sign. If the
value represents a configuration setting, an explanation will
be shown in parenthesis after the value. As an example,
ConfigurationOPTNLLCS = 1 (Circuit A leads).
Pressing the and keys simultaneously
will scroll an expanded text description of the point name or
value across the display. The expanded description is shown in
the local display tables but will not be shown with the path
names in text.
The CCN (Carrier Comfort Network
®
) point names are also
referenced in the local display tables for users configuring the
unit with CCN software instead of the local display. The CCN
tables are located in Appendix B of the manual.
Basic Controls Usage
SCROLLING MARQUEE DISPLAY — The scrolling mar-
quee display is the standard interface display to the ComfortLink
Control System for 30RAP units. The display has up and down
arrow keys, an key, and an key. These
keys are used to navigate through the different levels of the
display structure. Press the key until the highest
operating level is displayed to move through the top 11 mode
levels indicated by LEDs on the left side of the display. See
Fig. 1 and Tables 2-14.
Once within a mode or sub-mode, pressing the
and keys simultaneously will put the scrolling
marquee display into expanded text mode where the full mean-
ing of all sub-modes, items and their values can be displayed
for the current selection. Press the and
keys to return the scrolling marquee display to its default menu
of rotating display items (those items in Run Status
VIEW).
In addition, the password will be disabled, requiring that it be
entered again before changes can be made to password protect-
ed items. Press the key to exit out of the expanded
text mode.
NOTE: When the Language Selection (Configuration
DISP
LANG), variable is changed, all appropriate display
expansions will immediately change to the new language. No
power-off or control reset is required when reconfiguring
languages.
When a specific item is located, the item name alternates
with the value. Press the key at a changeable item
and the value will be displayed. Press again and the
value will begin to flash indicating that the value can be
changed. Use the up and down arrow keys to change the value,
and confirm the value by pressing the key.
Changing item values or testing outputs is accomplished in
the same manner. Locate and display the desired item. Press
so that the item value flashes. Use the arrow keys to
change the value or state and press the key to accept
it. Press the key to return to the next higher level of
structure. Repeat the process as required for other items.
Items in the Configuration and Service Test modes are pass-
word protected. The words ‘PASS’ and ‘WORD’ will alternate
on the display when required. The default password is 0111.
Press and the 1111 password will be displayed. Press
again and the first digit will begin to flash. Use the
arrow keys to change the number and press to accept
the digit. Continue with the remaining digits of the password.
The password can only be changed through CCN operator in-
terface software such as ComfortWORKS
®
, ComfortVIEW™
and Service Tool.
See Tables 2-14 and Appendix A for further details.
