maximum of 328 feet (100 meters)

between devices.

NOTE: Before May 2016, BAC-xxxxCE models

had a single Ethernet port. They now

have dual Ethernet ports, enabling

daisy-chaining of controllers

. See

the Daisy-Chaining Conquest Ethernet

Controllers Technical Bulletin on

the KMC Partner web site for more

information.

NOTE: On newer models, the Room Sensor

port is yellow

instead of black to

help differentiate it from the black

Ethernet ports.

NOTE: For more information, see Sample

(BAC-9311) Wiring on page 7 and the

YouTube video KMC Conquest Wiring:

BAC-9300 Series Unitary Controllers.

CAUTION

Do NOT connect 24 VAC to the analog

outputs (UO7–UO10 and GNDs)!

BAC-9300 Series Controller Installation Guide 4925-019-02G

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 ⊥

B. Connect the AC phase side of the

transformer to the controllers phase

terminal ∼

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

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

to ON.

NOTE: For more information, see Sample

(BAC-9311) Wiring on page 7 and the

YouTube video KMC Conquest Wiring:

BAC-9300 Series Unitary Controllers.

BAC-9300 Series Controller Installation Guide 5925-019-02G

Green READY LED

After controller power-up or restart is complete,

the READY LED flashes steadily about once per

second, indicating normal operation.

Amber (BACnet MS/TP) COMM LED

 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).

Green ETHERNET LED

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.

Amber ETHERNET LED

 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

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.
