.
18
17
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 specications.
NOTE: For more information, see Sample
(BAC-9311) Wiring on page 7 and the
YouTube video KMC Conquest Wiring:
BAC-9300 Series Unitary Controllers.
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.
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 Controller Installation Guide 5925-019-02G
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.
22
21
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, x 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, x the problem and
replace the bulb assembly.
