Page 4: Mounting The System Components
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 enclosure), complete the steps On a DIN Rail. -
Page 5: Mounting The Inclinometer
NOTE: Attach adequate strain relief (e.g. with wire ties) if needed to prevent the inclinometer from accidentally being pulled off of the damper blade during equipment maintenance. © 2021 KMC CONTROLS, INC. 19476 INDUSTRIAL DR. DRAWING TITLE: KMC CONQUEST A... -
Page 6: Mounting The Supply Airflow Pickup Tubes
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 7 In the Supply Air Duct (using SSS-101x) NOTE: The pressure flow pickup tubes should be mounted in filtered air in the location of laminar flow, which is about 6 straight duct diameters down the air duct. 1. Determine the duct’s flow direction and install the pickup tubes based on the flow arrow imprint. NOTE: The pickup tubes must be mounted with the arrow pointing in the direction of the airflow.

Page 8: Mounting Pickup Tubes For Pressure Assist
Mounting Pickup Tubes for Pressure Assist Mounting for OAD Pressure Assist Complete these additional steps only if installing a TRF-5901C-AFMS or TRF-5901CE-AFMS for an OAD pressure assist application. (See the TrueFit AFMS Selection Guide for details.) Mounting the First Pickup Tube 1. - Page 9 Mounting for RAD Pressure Assist Complete these steps only if installing a TRF-5901C-AFMS or TRF-5901CE-AFMS for a RAD pressure assist application. (See the TrueFit 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.

Mounting the Pressure Transducer(s) NOTE: Complete these steps only if using a TRF-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.

Connecting System Components to the Controller Connecting the Airflow Pickup Tubes For a TRF-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. -

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: Connecting The Return Air Temperature Sensor
Connecting the Return Air Temperature Sensor NOTE: Use 18 to 24 AWG shielded wiring for all connections. Do not locate the device wires in the same conduit with wiring used to supply inductive loads such as motors. 1. Feed the wire that will go to the AFMS controller through the bottom hole (if applicable). 2. -

Page 18: Connecting Networks
Connecting Networks Connecting an Ethernet Network For “E” models only, connect an Ethernet patch cable to the 10/100 ETHERNET port. CAUTION Do NOT plug a cable meant for Ethernet communications into the Room Sensor port! The Room Sensor port powers a NetSensor. The supplied voltage may damage an Ethernet switch or router. NOTE: The Ethernet patch cable should be T568B Category 5 or better and a maximum of 328 feet (100 meters) between devices. -

Page 21: Controller Power And Communication Status
Controller Power and Communication Status The status LEDs on a TRF-5901-AFMS and TRF-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. -
