CONNECT (OPTIONAL) MS/TP NETWORK 1. For BAC-93x1/93x1C models (only), connect
the BACnet network to the gray BACnet MS/ TP terminal block 15 .
15
NOTE: Use 18 gauge AWG shielded twisted pair cable with maximum capacitance of 51 picofarads per foot (0.3 meters) for all network wiring (Belden cable #82760 or equivalent).
A. Connect the A terminals in parallel with all other A terminals on the network.
B. Connect the +B terminals in parallel with all other +B terminals on the network.
C. Connect the shields of the cable together at each device using a wire nut or the S terminal in KMC BACnet controllers.
2. Connect the cable shield to a good earth ground at one end only.
NOTE: For principles and good practices when connecting an MS/TP network, see Planning BACnet Networks (Application Note AN0404A).
NOTE: The EOL switch is shipped from the factory in the OFF position.
3. If the controller is at either end of a BACnet MS/TP network (only one wire under the terminals), turn the EOL switch 16 to ON.
NOTE: For more information, see Sample (BAC-9311) Wiring on page 7 and the BAC-9300 series videos in the KMC Conquest Controller Wiring playlist.
16
CONNECT POWER
NOTE: Follow all local regulations and wiring codes.
1. Connect a 24 VAC, Class-2 transformer to the black power terminal block of the controller.
A. Connect the neutral side of the transformer
to the controllers common terminal 17 .
B. Connect the AC phase side of the transformer to the controllers phase
terminal 18 .
17
18
NOTE: Connect only one controller to each transformer with 12--24 AWG copper wire.
NOTE: Use either shielded connecting cables or enclose all cables in conduit to maintain RF emissions specifications.
NOTE: For more information, see Sample (BAC-9311) Wiring on page 7 and the BAC-9300 series videos in the KMC Conquest Controller Wiring playlist.
POWER AND COMMUNICATION STATUS
The status LEDs indicate power connection and network communication. The descriptions below describe their activity during normal operation (at least 5 to 20 seconds after power-up/initialization or restart).
NOTE: If both the green READY LED and the amber COMM LED remain OFF, check the power and cable connections to the controller.
BAC-9300 Series Controller Installation Guide
4
925-019-02I
Green READY LED 19 After controller power-up or restart is complete, the READY LED flashes steadily about once per second, indicating normal operation.
19
Amber (BACnet MS/TP) COMM LED 20 · During normal operation, the COMM LED flickers as the controller receives and passes the token over the BACnet MS/TP network. · When the network is not connected or communicating properly, the COMM LED flashes more slowly (about once a second).
20
Green ETHERNET LED 21 NOTE: The Ethernet status LEDs indicate network connection and communication speed.
· The green Ethernet LED stays ON when the controller is communicating with the network.
· The green Ethernet LED is OFF when the (powered) controller is not communicating with the network.
21
22
Amber ETHERNET LED 22
· The amber Ethernet LED flashes when the controller is communicating with a 100BaseT Ethernet network.
· The amber Ethernet LED remains OFF when the (powered) controller is communicating with the network at only 10 Mbps (instead of 100 Mbps).
NOTE: If both the green and amber Ethernet LEDs remain OFF, check the power and network cable connections.
MS/TP NETWORK ISOLATION BULBS
The two network isolation bulbs 23 serve three functions:
· Removing the (HPO-0055) bulb assembly opens the MS/TP circuit and isolates the controller from the network.
· If one or both bulbs are ON, the network is improperly phased. This means the ground potential of the controller is not the same as other controllers on the network. If this happens, fix the wiring. See Connect (Optional) MS/TP Network on page 4.
· If the voltage or current on the network exceeds safe levels, the bulbs blow, opening the circuit. If this happens, fix the problem and replace the bulb assembly.
