The BFC can control up to two ECM motors through a local setpoint which is adjustable using a push button interface on the BFC, by an analog BAS input voltage, or over BACnet. In addition to fan control, the BFC can monitor filter pressure drop, filter loading, signal for filter changes, monitor the motor and filter lifetime in hours, as well as report airflow and air temperature over the filter. This information can be viewed from the LCD screen on the front of the BFC controller, or over BACnet on a building management system. NOTE: This manual only covers the BFC controller. For troubleshooting an ECM motor, please visit http://www.priceindustries.com and download the ECM Motor Troubleshooting Manual.

Do not use standard power or “thermostat” wire. This wire does not have the necessary requirements for digital communications. While it’s possible it may work (temporarily) the network will be unreliable and not operating at optimal. BACnet MS/TP Wire type recommendations • Use 1 balanced twisted pair • Low capacitance (17pF or less) • Plenum rated (FT6, CMP ratings) • 100-120 ohm, Balanced • (CAT5, CAT5E, CAT6 network cable has excellent specifications and will work in almost any BACnet MS/TP application.) • Price recommends using the Orange (B/-) and Orange compliment (A/+) and Brown (NET COM) and Brown Compliment (NET COM) wire pair from a standard CAT5 cable. Also pre-terminated CAT5 cables are available from Price.

If the BAS signal drops below 1VDC local control (via the push buttons) is restored. BAS Voltage Response Notes 0-1 VDC Local control mode using push buttons 1-2 VDC Motor Off 2-9 VDC Modulating Control 2 – 9 VDC modulates motor from 0 – 100% 9-10 VDC Maximum Speed Motor is running at maximum speed (100%) Local setpoint can be adjusted from 0 – 100% using push buttons Recommend sending a 1.5 VDC signal to command motor off BAS equations exist in each fan powered terminal product service and installation manual to relate CFM to volts DC. The VDC in the equations however are for the 1-5 volt scale of voltage measured across the manual mode POT taps. The BAS input voltage is a 2-10 VDC scale, and therefore VDC calculated for a given CFM using the equation must be doubled to achieve that cfm using the BAS input. See standard speed controller BAS section for an example of calculating the voltage required for a specific CFM. If the BFC will be connected to BACnet, the BACnet motor speed setpoint will override both the BAS analog input, and the local setpoint for motor speed control. Motor speed setpoint priorities are: 1. BACnet 2. BAS analog signal 3. Local setpoint adjust 12 BACNet Flow Controller - Manual | priceindustries.com BACNet Flow Controller NETWORKING & SETUP Analog RPM Feedback A two wire connection supplies an analog (0-10 VDC) signal that is directly proportional to the MOTOR 1 RPM. The range is 0 – 2500 RPM and it will output a proportional 0 – 10 VDC signal. If a dual blower system is used, only the RPM of motor 1 can be read. NOTE: The minimum speed of an ECM is approximately 250 RPM. Formula for outputs below (tolerance +/- 5%): • VDC output = (RPM /250) • Rpm = (VDC * 250) Output signal: 0 – 10 VDC @ 20 k ohm minimum input impedance and is short circuit protected (output impedance is 511 ohm to protect against incorrect wiring). • Black Wire – Analog RPM output com (-) • White Wire – Analog RPM output signal (+) priceindustries.com | BACNet Flow Controller - Manual 13 BACNet Flow Controller NETWORKING & SETUP Wiring and Cables *For In depth ECM motor troubleshooting, please refer to ECM Troubleshooting Manual on Price Industries’ website. The ECM speed controller requires 24 VAC power from a transformer and outputs control signals to the ECM motor on dual MTA100 jacks. Either jack or both jacks can be used (for dual fan systems). The control cable (with RED connector) must be plugged into the circuit board correctly. (See Figure 2) FIGURE 2 - ECM STANDARD SPEED CONTROLLER WITH CONTROL CABLE PLUGGED INTO MTR1 MTR1 JACK ECM CONTROL CABLE (NOTE: ORIENTATION) NOTE: Make sure that this cable is connected properly. It is keyed one way, and make sure all of the pins are covered. 14 BACNet Flow Controller - Manual | priceindustries.com BACNet Flow Controller MAINTENANCE Troubleshooting Fault Solution Binary Outputs not functioning The Binary outputs send out 24VAC and are factory wired to the LED on the FFU-HE. Make sure the BFC has 24VAC power, and then check voltage at binary outputs and COM terminals if the LED does not light up. Analog Outputs not functioning The Analog outputs send out 0-10VDC. Make sure the BFC has 24VAC power, and then check voltage at the suspect analog output with a multimeter. You should see a voltage range of 0-10VDC. BACnet Communication Errors Option #1 BACnet - MS/TP is based on a RS-485 network. It must be wired in a daisy chain configuration. A daisy chain means that there is only one main cable, and every network device is connected directly along its path. DO NOT use Star, Bus, “T”, or any other type of network configuration. Any of these other network configurations will result in an unreliable network, and make troubleshooting almost impossible. Correct polarity is imperative on MSTP wiring. Always ensure that the positive terminal on a device has the same color wire connected to it throughout the network, same for the negative terminal.Eg. 2 wire conductor with black and white wires – black to the positive terminal, and white to the negative terminal. Keep this consistency throughout the network. Option #2 Price does not use EOL or termination on their devices. Terminating a device is almost never required at the low baud rate of MS/TP devices. In fact terminating can create more problems than it solves. The network speed or baud rate must be the same throughout the network. NOTE: The default speed for Price BACnet MS/TP controls is 76800. BACnet MS/TP currently supports 4 standard speeds which are: 9600, 19200, 38400 and 76800. Option #3 Binary Address must be unique for each device on the network. No two devices can have the same Address. This includes if you are incorporating a Price product into an existing network. Determine the existing Addressing scheme for the existing network. The Address is set on the Addressable dip switches on the UMCB. Option #4 Grounding and 24VAC polarity: Proper grounding is absolutely essential when wiring the MS/TP BACnet Network. Proper grounding will prevent many potential problems that can occur in a network of devices. Common symptoms of a poorly grounded network can include inconsistent BACnet MS/ TP communications and damage from voltage spikes. The most practical method of grounding is to ground every 24VAC transformer common/neutral used to power the controls. Connect the “common/neutral” wire of the SECONDARY side of the transformer to earth ground – such as the ground screw on in the electrical box. Option #5 NOTE: Flipping 24VAC HOT and COMMON will cause the BACnet MS/TP Network to stop communicating!!! Ensure HOT and COMMON are not reversed on ANY controllers. WARNING: Controllers will still power up and run even if HOT and COMMON are reversed. However output signals to other devices such as heaters, relays, etc will not work as intended! priceindustries.com | BACNet Flow Controller - Manual 15 BACNet Flow Controller MAINTENANCE Specifications Power: Pluggable 24 VAC, 50/60 Hz, 50 VA Class 2 Input Power: 24 VAC, 50/60 Hz, 5 VA (plus external loads), Class 2 Environmental (operating): 10°C to 50°C (50°F to 122°F), 0% to 95% RH (non-condensing) Environmental (storage): -30°C to 50°C (50°F to 122°F), 0% to 95% RH (non-condensing) 1 Thermistor Input (10K Ohm, Type J) Inputs: 2 Analog Inputs: 0-10 VDC 1 Contact Closure Input 3 Binary Outputs (24 VAC) for LEDs Outputs: 2 Analog Outputs (10 mA maximum, 0-10 VDC) 2 ECM motor connections Networking: BACnet (MS/TP) Indicators: BACnet RX/TX and Fault lights 16 BACNet Flow Controller - Manual | priceindustries.com BACNet Flow Controller MAINTENANCE BACnet points list for BFC firmware v1.10 Object Name Units Default Range Description R/W AO1 Analog Output 1 Volts DC N/A 0-10VDC Configurable for Unit Pressure, CFM, RPM, Filter Load and BAS R/W AO2 Analog Output 2 Volts DC N/A 0-10VDC Configurable for Unit Pressure, CFM, RPM, Filter Load and BAS R/W AO3 ECM Setpoint % 50 0-100 Set ECM motor setpoint R/W AI1 Analog Input 1 (BAS) Volts DC Dynamic Dynamic Analog Output can be tied to several signals.
