Introduction
The Carrier TruVu™ Isolated Network Router, model TV-ISO-E2, is a crucial component for establishing and managing network communications within HVAC systems. This guide details the essential steps for its installation and initial setup, ensuring seamless integration and optimal functionality.
Key features include:
- Facilitates BACnet routing between various BACnet communication types.
- Acts as a BACnet Broadcast Management Device (BBMD) for BACnet/IP networks.
- Supports Foreign Device Registration (FDR) and DHCP IP addressing.
- Includes built-in network diagnostic capabilities for efficient troubleshooting.
- Compatible with the i-Vu® system, version 9.0 and later.
Key Features and Specifications
The TV-ISO-E2 offers robust connectivity options:
- Primary Port: 10/100 BaseT Ethernet for BACnet/IP, BACnet/IPv6, BACnet/Ethernet, and BACnet/SC.
- Isolated Port: 10/100 BaseT Ethernet for BACnet/IP, providing isolated network communication.
- Port S1 & S2: High-speed EIA-485 for BACnet/MSTP communication, supporting baud rates from 9600 to 115200 bps.
- Service Port: USB 2.0 host for configuration and troubleshooting via a local connection.
The device is powered by a 24 VAC +/- 10% or 24 VDC +/- 10% source, with a power consumption of 50 VA or 18 W respectively. It operates within an environmental range of -40 to 158°F (-40 to 70°C) and 10-95% relative humidity, non-condensing.
Installation and Mounting
The TV-ISO-E2 can be mounted using either a 35mm DIN rail or screw mounting. For high temperature and high humidity environments, screw mounting is recommended.
DIN Rail Mount: Hook the device onto the DIN rail and push until it clicks into place.
Screw Mount: Use #6 screws through the mounting holes, ensuring a torque of no more than 8 in.lbs.
Wiring and Power
WARNING: Do not apply line voltage to the device's ports and terminals. The TV-ISO-E2 is powered by a Class 2 power source.
Follow these steps for wiring:
- Remove power from the power supply.
- Connect the power supply wires to the red screw terminal connector labeled 24 Vac/Vdc (+/-).
- Ensure a negative terminal from the power supply is connected to earth ground with an 18 AWG or larger wire, not exceeding 12 inches.
- Apply power and verify the voltage is within the 20.4 to 28.8 Vac or 21.6 to 28.8 Vdc range.
- Insert the terminal connector into the device and verify the POWER LED is illuminated.
Connecting to the Device
The TV-ISO-E2 can be connected via the USB Service Port using a wireless adapter or a USB cable. Navigate to https://local.access or https://169.254.1.1 in a web browser to access the controller setup pages.
