16Table 10 — EMM Board Inputs and OutputsLocal Equipment Network — Information is trans-mitted between modules via a 3-wire communication bus orLEN (Local Equipment Network).Board Addresses — All boards (except the Touch Pilotdisplay and the Energy Management Module board) have DIPswitches to set the address.Control Module CommunicationRED LED — Proper operation of the control boards can bevisually checked by looking at the red status LEDs (light-emitting diodes). When operating correctly, the red statusLEDs will blink in unison at a rate of once every 2 seconds.If the red LEDs are not blinking in unison, verify that cor-rect power is being supplied to all modules and that all com-munication wiring is connected securely. Be sure that theTouch Pilot™ module is supplied with the current software.If necessary, reload current software. If the problem stillpersists, replace the Touch Pilot module. A red LED that islit continuously or blinking at a rate of once per second orfaster indicates that the board should be replaced.GREEN LED — All boards have a green LEN (LocalEquipment Network) LED which should be blinking when-ever power is on. If the LEDs are not blinking as describedcheck LEN connections for potential communication errorsat the board connectors. A 3-wire bus accomplishes com-munication between modules. These 3 wires run in parallelfrom module to module. They connect to J9 on EMM andAUX boards, and to J12 or J13 on SIOB boards. A validunit configuration must be in the Touch Pilot module forproper LEN communication.Carrier Comfort Network ® (CCN) Interface —All 30XV units can be connected to the CCN, if desired. Thecommunication bus wiring is a shielded, 3-conductor cablewith drain wire and is field supplied and installed. The systemelements are connected to the communication bus in a daisychain arrangement. The positive pin of each system elementcommunication connector must be wired to the positive pins ofthe system elements on either side of it. The negative and sig-nal ground pins of each system element must also be wired inthe same manner. Wiring connections for CCN should be madeat TB3. Consult the CCN Contractor’s Manual for further in-formation. See Fig. 19.NOTE: Conductors and drain wire must be 20 AWG(American Wire Gage) minimum stranded, tinned copper.Individual conductors must be insulated with PVC, PVC/nylon, vinyl, Teflon*, or polyethylene. An aluminum/polyester 100% foil shield and an outer jacket of PVC,PVC/nylon, chrome vinyl, or Teflon with a minimumoperating temperature range of –20 C to 60 C is required.See Table 11 for recommended wire manufacturers andpart numbers.Table 11 — CCN Communication Bus WiringCHANNEL IN/OUTTYPEBOARDCONNECTOR CCN POINT POINTDESCRIPTIONI/O POINTNAMEINPUT/OUTPUTTYPECH 01 AIJ6— — AI-01 5/10K ThermistorCH 02 AI SPACETMP Space temperature AI-02 10K ThermistorCH 03 AI — — AI-03 5/10K ThermistorCH 04 AI — — AI-04 5/10K ThermistorCH 05 AI J7A SP_RESET Setpoint reset AI-06 0-5VCH 06 AI J7B LIM_ANAL Capacity limit AI-07 0-5VCH 07 AO J8 CAP_T % Total capacity running AO-01 0-10VdCCH 08 DI J4, CH8 OCC_OVSW Occupancy override DI-01 —CH 09 DI J4, CH9 LIM_SW2 Demand limit SW2 DI-02 —CH 10 DI J4, CH10 REM_LOCK Remote lockout switch DI-03 —CH 11a DI J4, CH11A ICE_SW Ice done DI-04 —CH 11b DI J4, CH11B — — DI-05 —CH 12 DI J5, CH12 — — DI-06 —CH 13 DI J5, CH13 — — DI-07 —CH 14 DI J5, CH14 — — DI-08 —CH 15 DI J5, CH15 — — DI-09 —CH 16 DO J2A CP_A Compressor A run status DO-01 TriacCH 17 DO J2A CP_B Compressor B run status DO-02 TriacCH 18 DO J2A — — — —CH 19 DO J2A — — — —CH 20 DO J2B — — — —CH 21 DO J2B — — — —CH 22 DO J2B — — — —CH 23 DO J2B — — — —CH 24 DO J3 SHUTDOWN Shutdown relay DO-09 RelayCH 25 DO J3 ALERT Alert relay DO-10 RelayMANUFACTURER PART NUMBERRegular Wiring Plenum WiringAlpha 1895 —American A21451 A48301Belden 8205 884421Columbia D6451 —Manhattan M13402 M64430Quabik 6130 —*Teflon is a registered trademark of DuPont.
