Next, the ADDRESS will become highlighted. Using the same procedure that was used for choosing the correct BUS, select the proper address. Press EXIT when finished. NOTE: By holding either the INCREASE or DECREASE softkey in, the display will automatically scroll one number at a time until it reaches a factor of 0, and then it will increase or decrease by increments/ decrements of 0 to facilitate faster selection. NOTE: For 30GX,HX applications, if the chiller is a standalone installation, then the bus number will be 0, and the address number is. If the chiller is installed on the Carrier Comfort Network, then the bus and address (element) numbers may be different. Usually this information is written on the side of the PSIO- controller. The information can also be accessed from the standard HSIO display, by pressing and using the down arrow key to display the setting for Target Address and Bus Number. NOTE: For 48/50E series units the default bus number is 0 and the default address is. 7. The remote enhanced display will now try to communicate with the selected device. If the selected device is not found on the bus, the display will reply COMMUNICA- TION FAILED. If the selected device is found the display will show the controller name (unless it is the first device listed in which case it will always display LOCAL). Press the ATTACH softkey and the LID-2B will upload the controller. When the remote the tables are being uploaded the message UPLOADING TABLES flashes at the bottom of the screen. It may take several minutes for the tables to load. NOTE: The LID-2B can only attach to one controller at a time. 8. Once the uploading process is complete, the display will show the default screen for 30GX,HX applications; or for 48/50E series applications, the controller ID screen will appear showing pertinent information of the controller. See Fig. 8 and 9. The enhanced display is ready for use. NOTE: For 30GX,HX applications, all of the information that is available through the HSIO display can also be accessed through the LID-2B enhanced display. Table 6A outlines the functions and subfunctions that are available through the HSIO display.
