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.
- Page 21 Installation & Operation Manual - Model AVT6000 The Airflow Volume Gauge provides the real-time measurement of the volumetric air flowing through the AccuValve. The range of this gauge is determined by the size of the valve and it cannot be reset in the field. 6.5.3 Valve Airflow Gauge The Valve Airflow Volume Gauge provides the real-time measurement of the volumetric air flowing through the AccuValve.
- Page 22 Installation & Operation Manual - Model AVT6000 6.5.5 Analog Output Configuration The AVT’s Analog Output is primarily used to provide an analog signal representing the Airflow Volume flowing through the valve. The signal type and full-scale range of the Analog Output are user-defined values that are configured by clicking on the boxes adjacent to each heading.
- Page 23 Installation & Operation Manual - Model AVT6000 6.5.6 Sensor Frequency Signals The AccuValve measures airflow using vortex shedders that are incorporated in the compression zone of each chamber inside the valve. Each vortex shedder provides an independent frequency-based signal that is directly proportional to the air flowing through the chamber.

- Page 26 Installation & Operation Manual - Model AVT6000 The primary application for AccuNet is in laboratories that have multiple VAV fume hoods which require the total lab exhaust airflow to be instantly tracked by the supply airflow to maintain the proper room pressurization. AccuValves must be equipped with the optional AccuNet Module to operate on the AccuNet Network.

Description AccuNet™ is a high-speed serial bus that is designed to provide a room-level network for summing the airflow volume of multiple AccuValves while providing a single analog signal representing the total sum of the AccuValve airflows. - Page 39 Installation & Operation Manual - Model AVT6000 How to Field-Configure the AccuNet Network Devices Each AccuValve on the network must be field-configured using the AccuValve Insight Program for the purpose of; assigning a unique network address to each device, associating each device on the network with one another, and configuring one device as the network Totalizer.
- Page 40 Installation & Operation Manual - Model AVT6000 Step 3: Configure each AccuValve in the Network (this example is a 4 AccuValve network) 3-1. Configure the first AccuValve in the network. 3-1a. Connect to the first AccuValve on the network and open AccuValve Insight. 3-1b.
- Page 41 Installation & Operation Manual - Model AVT6000 The utility will now assign a unique network address to this AccuNet Module and AccuValve TAG name will be assigned as the TAG name of this AccuNet Module. 3-3d. Close Insight and disconnect from the AccuValve. 3-4.
- Page 42 Installation & Operation Manual - Model AVT6000 Each item that was configured in Step 3 should appear in the list. If any devices are missing, there may be problem with the physical network or one of the devices was not configured properly. If only the Totalizer appears on the list, check the network wiring and verify the 120-ohm termination resistors are installed on each end of the network.
