BAC-5900 Series Controller Installation Guide 6925-019-01J
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.
Green READY LED
25
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
26
• 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).
26
Green (EIO) COMM LED
27
The Expansion Input Output (EIO) status LED indicates
EIO network communication with one or more CAN-5901
expansion modules. After controller power-up or restart,
the LED flickers as it receives and passes the token:
• The EIO LED flashes when the controller is
communicating with the EIO network
• The EIO LED remains OFF when the (powered)
controller is not communicating with the EIO
network. Check the power and EIO network
connections.
NOTE: See the CAN-5901 I/O Expansion Module
Installation Guide for more information.
27
Green ETHERNET LED
28
The Ethernet status LEDs indicate network connection
and communication speed.
• The green Ethernet LED is 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.
2928
Amber ETHERNET LED
29
• 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.

BAC-5900 Series Controller Installation Guide 7925-019-01J
MS/TP NETWORK ISOLATION BULBS
30
The two MS/TP network isolation bulbs
30
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.
CONFIGURE/PROGRAM THE CONTROLLER
See the table for the most relevant KMC Controls tool for
configuring, programming, and/or creating graphics for
the controller. See the tools' documents or Help systems
for more information.
NOTE: After the controller has been configured, an
STE-6010/6014/6017 series analog sensor
can be connected to the controller in place
of an STE-9000 series digital NetSensor.
NOTE: A BAC-5901CEcan be configured by
connecting an HTML5-compatible web
browser to the controller’s default IP
address (192.168.1.251). See the Conquest
