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.
