GTx116 TRANSMITTER INSTALLATION The GTx116 transmitter is designed for use in an environment between -20° F to 120° F (-28.8° C to 48.8° C) where it will not be exposed to rain or snow. The transmitter should be mounted upright in a field accessible location. The enclosure (Figure 4) is designed to accept 1/2 in.
Figure 5. GTx116 Power Connections Multiple GTx116 transmitters wired to a single transformer must be wired “in-phase” (L1 to L1, L2 to L2). EBTRON, Inc. 1663 Hwy. 701 S., Loris SC 29569 • Toll Free: 800.2EBTRON (232.8766) • Fax: 843.756.1838 • Internet: EBTRON.com...
After mounting the sensor probes and transmitter, connect one or more sensor probe cable plugs to the circular recep- tacles located at the bottom of the GTx116 transmitter enclosure. Probes are “Plug and Play” and do not have to be con- nected to a specific receptacle on the transmitter (unless traverse data is desired - see note below).
Figure 8). In addition, when the Analog Output is concurrently used with the RS-485 Output, the Common connection for both Analog and RS-485 Outputs must be at the same potential.

Changing the System of Units - IP units or SI Units The GTx116 transmitter is provided with the system of units set to I-P. To change to S.I., simultaneously press and release the “ENT” and “ESC” buttons during normal operation. “IP/SI UNITS” will be indicated on the LCD display. Refer to Appendix B SYSTEM OF UNITS MENU for details on the System of Units menu.
Factory Default Menu Settings for GP1 Sensor Probes The GTx116 transmitter is “plug and play” and does not require setup unless a network option is selected that requires configuration. Table 4 shows the factory default settings for all compatible sensor probes.
(in FPM) by the free area of the air flow probe installation location. Refer also to Table 6 for a complete listing of conversions for each of the analog outputs of the GTx116. The AO1 full scale analog output (OUT- PUT1 ) value is determined by the AO1 FS setting within the SETUP menu.
Airflow and temperature of individual sensors can be displayed on the local LCD display by entering the Diagnostic Menu. Simultaneously depress the up ↑ and down ↓ arrows to enter the GTx116 SETUP menu, and then navigate to the Diagnostic submenu.

The node object is used for overhead activities on the LonWorks bus. This object is of little interest to the end user. The gtx116 function block contains a set of network variables and configuration properties that allow the end user to monitor various parameters related to airflow, pressure, and temperature that are generated by the transmitter.
This configuration property sets the duct area to be used in flow calculations. Note that this variable must be set to a non-zero value to get flow information. EBTRON, Inc. 1663 Hwy. 701 S., Loris SC 29569 • Toll Free: 800.2EBTRON (232.8766) • Fax: 843.756.1838 • Internet: EBTRON.com...

EB-Link card and/or the transmitter. The EB-Link card must be installed on the GTx116 main board in order to access sensor data with your PDA. If the EB- Link card is ordered separately from the transmitter, it should be installed after the transmitter is mounted.
If traverse data is desired, ensure that probes are installed using the mounting convention specified in Figure 10. Proper instal- lation simplifies sensor location decoding during data analysis.
