Page 4 Mounting the System Components Mounting the Controller NOTE: Mount the controller inside a metal enclosure for RF shielding and physical protection. NOTE: To mount the controller with screws on a flat surface, complete the steps in On a Flat Surface Or to mount the controller on a 35 mm DIN rail (such as integrated in an HCO-1103...
Page 5 4. Lower the controller against the DIN rail. 5. Push in the DIN latch to engage the rail. NOTE: To remove the controller, pull the DIN latch until it clicks once and lift the controller off the DIN rail. Mounting the Inclinometer NOTE: If the outside air damper has vertical-axis damper blades, you will first need to install an HLO-1050 Linkage Kit...
Page 6 Mounting the Supply Airflow Pickup Tubes There must be enough pressure flow pickup tubes must installed, for the size of the opening, to get an accurate average value for the air-stream. Multiple pickup tubes (at least 2) connected in a parallel pitot array are recommended.

Page 8 Mounting Pickup Tubes for Pressure Assist Mounting for OAD Pressure Assist Complete these additional steps only if installing a BAC-5901C-AFMS or BAC-5901CE-AFMS for an OAD pressure assist application. (See the KMC AFMS Selection Guide for details.) Mounting the First Airflow Pickup Tube 1.
Page 9 Mounting for RAD Pressure Assist Complete these steps only if installing a BAC-5901C-AFMS or BAC-5901CE-AFMS for a RAD pressure assist application. (See the KMC AFMS Selection Guide for details.) Mounting the First Airflow Pickup Tube 1. Find a location for the first pickup tube near the return air damper, on the damper’s upstream side. 2.
Page 10 Mounting the Pressure Transducer(s) NOTE: Complete these steps only if using a BAC-5901C(E)-AFMS controller. NOTE: Avoid locations with severe vibrations or excessive moisture. The enclosure has a standard 1/2-inch conduit opening and may be installed with either a conduit coupler or a cable-gland-type fitting. CAUTION Do not use in explosive or hazardous environments, with combustible or flammable gasses, as a safety or emergency stop device, or in any other application where failure of the product could...
Page 11 Mounting the OAT, RAT, and MAT Sensors STE-1411/12/13/14 Bendable Copper Sensor Use a bendable copper sensor for easily-accessible mixed air sections and outside air hoods. If the mixed air section is not easily accessible, a flexible cable sensor may be used. If the unit does not have an easily- accessible outside air hood, a rigid steel probe may be used.
Page 12 2. Insert the sensor cable into the mixed air chamber, stringing the cable to cover the air path, and secure as needed. NOTE: The flexible cable can be easily shaped to fit any duct size but observe a minimum bend radius of two inches to prevent damage to wires or sensors.

Page 14 Connecting System Components to the Controller Connecting the Airflow Pickup Tubes For a BAC-5901C(E)-AFMS Use appropriately sized polyethylene tubing for the pressure connections. The length of the tubing should not be longer than necessary. Arrange the tubing to minimize stress on the connections and prevent kinking. Connecting the Supply Airflow Pickup Tubes to the Pressure Transducer 1.
Page 15 NOTE: The other ports of the two pickup tubes are left unconnected and open to air. Connecting the Pressure Transducer(s) to the Controller 1. Connect the signal wire from OUT on the supply air pressure transducer to UI9 on the controller. 2.
Page 16 NOTE: The two-wire sensor is not polarity sensitive. 3. Plug the conduit with sealant to prevent air infiltration. 4. Swing the door closed until securely latched. 5. If desired for added security, install the two (provided) screws in the door’s integrated screw tabs. 6.

Page 18 • Subnet mask—255.255.255.0 • Gateway—192.168.1.1 Connecting an MS/TP Network 1. For a BAC-5901C-AFMS or BAC-9311C-AFMS, 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).
Page 19 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: The EOL switch is shipped from the factory in the OFF position. KMC Airflow Measurement System Installation Guide 925-019-05D...

Page 22 Controller Power and Communication Status The status LEDs on a BAC-5901-AFMS and BAC-9311-AFMS 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.
Page 23 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). Controller MS/TP Network Isolation Bulbs The two network isolation bulbs serve three functions:...
