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 28 After controller power-up or restart is complete, the READY LED flashes steadily about once per second, indicating normal operation. Amber ETHERNET LED 31 · 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. Amber (BACnet MS/TP) COMM LED 29 · 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). 29 28 Green ETHERNET LED 30 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. BAC-9000 Series Controller Installation Guide MS/TP NETWORK ISOLATION BULBS 32 The two network isolation bulbs 32 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 5. · 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. 6 921-019-01L WATCH DOG JUMPER The watch dog jumper 33 resets the controller if there is a power failure or a communication timeout between the controller and the network. Never remove the jumper (from the two outer pins). For instructions on VAV balancing: · With an STE-9000 series NetSensor, see the VAV Airflow Balancing with an STE-9xx1 section of the KMC Conquest Controller Application Guide. · With a BAC-5051E Router, see its application and installation guide. · With KMC Connect or TotalControl, see the Help system for the software. 33 CONFIGURE/PROGRAM THE CONTROLLER See the table (on the next page) for the most relevant KMC Controls tools 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 STE9000 series digital NetSensor.
