Ethernet Port
The Ethernet port is 10/100 Base T with an RJ connector and supports BACnet IP, Modbus TCP/IP and EtherNet/IP protocols.
The Ethernet option must be ordered with the transmitter. For Energy models, the Ethernet option is not available with the
Totalizing Pulse option.
See”Communications Protocols” on page66 for information on configuring Ethernet settings.
USB Programming Port
The USB programming port is a USB 2.0 Type B connector similar to the USB port on many printers. The USB programming
port on the transmitter is the cable connection point from a computer with UltraLink software. UltraLink is used for
configuring, calibrating and troubleshooting the meter.
See “Parameter Configuration Using UltraLink Software” on page48 for further details.
HEAT FLOW FOR ENERGY MODEL ONLY
The Energy model allows the integration of two 1000 Ohm, platinum RTDs with the transmitter, effectively providing an
instrument for measuring energy consumed in liquid heating and cooling systems. RTDs ordered with the Energy model are
factory calibrated and shipped with the transmitter.
The Energy model has multiple heat ranges. Select the range that encompasses the temperature range of your application.
The three-wire surface-mount RTDs are attached at the factory to a plug-in connector. Install the RTDs on or in the pipe as
recommended, and then plug the RTDs into the RTD connector in the transmitter.
Four ranges of surface-mount RTDs and two lengths of wetted insertion probes are offered. Other cable lengths for surface
mount RTDs are available. Contact the manufacturer for additional offerings.
All RTDs are 1000 Ohm platinum, three-wire devices. The surface-mount RTDs are available in standard lengths of 20 feet
(6 meters), 50 feet (15 meters) and 100 feet (30 meters) of attached shielded cable.
Installing Surface-Mounted RTDs
Use surface-mount RTDs on well insulated pipe. Use insertion (wetted) RTDs on pipes that are not insulated.
1. Select areas on the supply and return pipes where the RTDs will be mounted.
2. Remove or peel back the insulation all the way around the pipe in the installation area.
3. Clean an area slightly larger than the RTD down to bare metal on the pipe.
4. Place a small amount of heat sink compound on the pipe in the RTD installation location. See Figure 37.
5. Press the RTD rmly into the compound. Fasten the RTD to the pipe with the included stretch tape.
6. Route the RTD cables back to the transmitter and secure the cable so that it will not be pulled on or abraded inadvertently.
7. Replace the insulation on the pipe. Check that the RTDs are not exposed to air currents.
