Installation & Operation Manual - Model AVT6000

SECTION 1 - INTRODUCTION
The AVT6000 product family is intended for applications that require accurate and repeatable
airflow measurement with high turn-down that achieves precise control using an external PI
controller. The AVT6000 incorporates a state-of-the-art vortex shedding digital transmitter
with an intuitive user-interface software known as the AccuValve Insight.
1.1 Theory of Operation (Reference the Diagram Below)
The AccuValve®divides the airflow into two equal chambers using an airfoil shaped
compression section. Each chamber is comprised of a vortex shedding airflow sensor, a
modulating control surface and a static regain section. As air enters the chambers it accelerates
and compresses, creating an ideal condition for measuring airflow velocity. The vortex
shedding airflow sensors provide a highly repeatable digital pulse-train with a frequency that is
directly proportional to the air flow velocity in each chamber of the AccuValve®.
The digital pulses generated by each vortex shedding sensor are used to calculate the total
airflow volume flowing through the AccuValve®. The transmitter provides a software-
selectable analog output signal that is directly proportional to the total airflow volume
measurement. The airflow volume can also be provided directly to the building management
system’s BACnet MS/TP network by ordering the optional BACnet MS/TP communications
module.
Field configuration is accomplished through AccuValve Insight, which is an intuitive user-
interface software. Connection between the AVT and the computer is provided through a USB
port located on the AVT transmitter or using the optional Bluetooth connection.

SECTION 4 - INSTALLATION
Read all instructions and review the installation diagrams provided on the following pages prior
to beginning installation. Also reference the product submittal drawings before proceeding.
CAUTION: Wear eye protection, cut-resistant gloves, and clothing suitable for working
with sheet metal. Failure to do so may result in personal injury.
1. Verify the tag number located on the valve label matches the HVAC schedule.
2. Locate the duct section which the valve is servicing and select a suitable mounting
location for the valve.
NOTE: the AccuValve does not require straight-run inlet conditions to operate properly,
however it’s always best to follow HVAC Best Practices for Commercial Buildings during
installation which includes locating the valve away from transitions and bends to
minimize impact on system static pressure. Also, be sure to select a location that will
provide a minimum clearance of 14” (356mm) unobstructed access to the transmitter,
actuator and valve access cover.
3. Provide an opening in the duct section sized appropriately for the valve being installed.
NOTE: A slip-fit valve will require an opening approximately 2” smaller than the valve
length and a flanged valve will require an opening the same as the valve length. For
valve dimensions, reference Section 4.
4. Install duct hangers within 12” (305mm) from each end of the valve connections.
Reference Section 4 for valve weights.
WARNING:Use duct hangers and hardware designed to support the total load of the
valve and associated duct sections. Failure to do so may result in serious personal injury
or death.
5. Install the valve into the duct in accordance with the airflow direction label located on
the valve. Position the valve for easy access to the transmitter side. Since the
AccuValve is not position sensitive, it can be installed in any plane or rotational axis
without having impact on the performance.
NOTE: Screws, nuts, fasteners, duct sealant, hangers, companion flanges and gaskets
are NOT provided by Accutrol.

Note: If 24VAC is applied and the USB is connected beforehand, or if the
switch position is changed while a USB connection is active, the
transmitter will revert to bootloader mode and will not function properly.
Note: If a transmitter is in bootloader mode, disconnect the USB,
disconnect the 24VAC power, ensure the power source switch is set to
the “operational position”, and wait 5 seconds. After these steps,
reconnecting 24VAC power first will resume normal operation.
6.4 Connecting the PC to the AVT Transmitter
6.4.1 Connecting to a standard AVT6000 using a USB cable.
6.4.1.1 Power Source Switch
The AVT6000 transmitter has a Power Source Switch which should always be in the
“Operational Position” for the transmitter to function normally. The “Nonoperational
Position” is provided so the transmitter can be programmed or configured when there is no
24v power source available. This is a convenient feature for configuring the BACnet
parameters or the transmitter’s analog output prior to having the 24v power source wired.
Operational Position
Nonoperational Position
24v power is provided to the transmitter
through the 24v connector. This is the
normal position for the Power Source
Switch.
5vdc power is provided to the
transmitter through the computer
connected to the USB Configuration Port.
This is a temporary position only.
Note: The Power Source Switch must be returned to the Operational Position after
completing the configuration otherwise the transmitter will not function.

6.5.1 Configuring USB Driver
In some instances, the Windows 10 machine being used to run Insight may not be equipped
with the appropriate USB driver package needed to connect. This is a possible occurrence with
new machines which have never downloaded this driver package. This can be fixed by now
downloading the driver package which Accutrol has provided.
If the correct driver is missing, insight will likely display “No Accutrol Device Located” after
clicking Locate Accutrol USB Devices despite the PC being connected to the transmitter board.
Should troubleshooting indicate that a missing driver is the problem; follow the steps listed
below:
1. Navigate to the unzipped Zip file named “Accuvalve Insight”that was already
downloaded to your pc.
2. Within this folder is another Zip file called CP210x_Windows_Drivers.
3. Extract the contents of this .zip file and enter the unzipped folder.

4. Find the .exe files called “CP210xVCPInstaller” and run the x64 version or x86 version
depending on the type of operating system that’s on your pc.
5. After installation, Insight should successfully locate a COM port when connected to an
AccuValve transmitter.
Note: It may be necessary to restart your PC after installation of the CP2120x driver for
the install to take effect.
