  • Page 5: Overview

    “Additional Resources, ” p. BACnet Testing Laboratory (BTL) Certification The BCI-I supports the BACnet communication protocol and has been designed to meet the requirements of the application-specific control profile. For more details, refer to the BTL web site at www.bacnetassociation.org.

    4. Click the Connect button and the Tracer TU main page will appear after successful connection. Note: The BCI-I may be powered via the USB cable or 24 Vac from the HVAC unit. Concurrent connection of unit power and the USB cable will not harm the BCI-I device.

  • Page 7: Ip Units Configuration

    Configuration. IP Units Configuration The BCI-I supports both inch-pound and SI (metric) units of measure. The factory default units of measure is SI. The device allows only a change of units for all objects as a whole. Mixed units of measure is not allowed.

    6. Apply power to the HVAC equipment. Change Device ID By default, the BCI-I device sets its device ID to the same value as the one defined by the rotary switches (MS/TP MAC address) on the front of the device. Refer to the section, “Rotary Switches, ”...

  • Page 9: Stand-Alone Or Bas Operation

    The control system on HVAC equipment has the ability to operate the unit as a stand-alone system or as part of a building automation system. The BCI-I (either factory or field installed), by default, is configured for stand-alone operation. This configuration enables the HVAC equipment to operate prior to the commissioning of the unit into the BAS.

  • Page 10: Periodic Update Of Bas Values

    If the length of time exceeds a predefined limit, the BCI-I will place the object into the fault state and revert to a unit-supplied sensor value for control. At power up, the sensor objects are set to a fault state and they will remain in this state until a write is detected.

  • Page 11: Diagnostics Reset Command

    The BAS will change the state of the Filter Timer Reset Command object (BO 13) to the active state. Upon the change to active state, the BCI-I will set the present value of the Filter Runtime Hours object to zero and then set the Reset Command object back to the inactive state.

  • Page 12: Timestamp Configuration

    To minimize the possibility that the unit timestamp is not representing the actual time, the BAS should be setup to periodically synchronize the device time clock with the BAS clock using the BACnet TimeSynchronization service. ACC-SVP01B-EN • BCI-I Integration Guide...

  • Page 13: Bci Intellipak Rotary Switches And Leds

    This section provides information about the BCI-I rotary switches and LED displays. Rotary Switches There are three rotary switches on the front of the BCI-I device that are used to define a three-digit address when the BCI-I is installed on a BACnet communications network. The three-digit address setting is the BACnet MAC address.

  • Page 14: Leds Description, Behavior, And Troubleshooting

    LEDs Description, Behavior, and Troubleshooting There are 15 LEDs on the front of the BCI-I unit. However, LEDs BO1 through BO9 are not used for the BCI-I controller. Figure 2 shows the locations of each LED. The following table provides a description of each LED activity, an indication or troubleshooting tips for each, and any notes.
