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.

Page 10: Mounting The Pressure Transducer(S)
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
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 22: Controller Power And Communication Status
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: Controller Ms/Tp Network Isolation Bulbs
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).
