Local Equipment Network

Information is transmitted between modules via a 3-wire com-
munication bus or LEN.

Board Addresses

All boards (except the Carrier Controller display and the Energy
Management Module) have DIP switches to set the address.

Control Module Communication

RED LED
Proper operation of the control boards can be visually checked
by looking at the red status LEDs (Light-Emitting Diodes).
When operating correctly, the red status LEDs will blink in
unison at a rate of once every 2 seconds. If the red LEDs are
not blinking in unison, verify that correct power is being sup-
plied to all modules and that all communication wiring is con-
nected securely. Confirm current version of software installed
on SmartView panel by navigating to Control Identification

Menu (Main Menu Configuration Menu

uration Menu Control Identification Menu
Part Number). If a newer version of the software exists, con-
tact your Carrier service representative service to reload current
software. If the problem still persists, replace the Carrier Con-
troller module. A red LED that is lit continuously or blinking at
a rate of once per second or faster indicates that the board
should be replaced.
GREEN LED
All boards have a green LEN LED which should be blinking
whenever power is on. If the LEDs are not blinking as de-
scribed check LEN connections for potential communication
errors at the board connectors. A 3-wire bus accomplishes

communication between modules. These 3 wires run in parallel
from module to module. They connect to J9 on EMM and
AUX boards, and to J12 or J13 on SIOBs. A valid unit config-
uration must be in the Carrier Controller module for proper
LEN communication.
Carrier Comfort Network
All 30XV units can be connected to the CCN, if desired. The
communication bus wiring is RS-485 Communication Wiring,
CM or CMP rated consisting of a shielded, 3 conductor cable
with drain wire and is field supplied and installed. The system
elements are connected to the communication bus in a daisy
chain arrangement. The positive pin of each system element
communication connector must be wired to the positive pins of
the system elements on either side of it. The negative and signal
ground pins of each system element must also be wired in the
same manner. Wiring connections for CCN should be made at
TB3. See Fig. 22. For noise consideration, communication wir-
ing must be separate and not run in parallel with other wiring.
NOTE: Conductors and drain wire must be 20 AWG (American
Wire Gage) minimum stranded, tinned copper. Individual con-
ductors must be insulated with PVC (Polyvinyl Chloride), PVC/
nylon, vinyl, Teflon 1 , or polyethylene. An aluminum/polyester
100% foil shield and an outer jacket of PVC, PVC/nylon,
chrome vinyl, or Teflon with a minimum operating temperature
range of –20°C to 60°C is required. High temperature applica-
tions may require a higher temperature range. Plenum applica-
tions will require plenum rated cable. Cable voltage require-
ments must match the application.
