Installing the ZFR1831 Wireless Router to a Smart Equipment RTU controller - Johnson Controls - LIT-12013765 - Wireless field bus - Smart Equipment Control

To install the ZFR1831 Wireless Router to the Smart Equipment controller, complete the following steps:

1. Refer to the ZFR1831 Pro Series Wireless Router Installation Guide (Part No. 24-114610-0004).
   Note: Setting FCBusMode to “Wireless Field Bus” (located in Controller > Network menu) enables the Smart Equipment controller to operate in a wireless mode using the WRG1830/ZFR183x Pro Series Wireless Field Bus System. Set the Smart Equipment controller FCBusMode to “Wireless Field Bus” for wireless operation. Set the Smart Equipment controller FCBusMode to “Wired Field Bus” for hard-wired BACnet MS/TP operation.
   Note: Do not connect the ZFR Pro Router to the Smart Equipment controller before setting the PAN OFFSET switches.
2. Set the ZFR1831 Router’s PAN OFFSET switches according to the job drawings.
   Note: When selecting a PAN OFFSET for a wireless network, consider the following points:
   1. All devices within one wireless mesh network must be set to the same PAN setting.
   2. Select PAN settings that are unique for the site.
   3. Set the AREA rotary switch to 0.

   Important: To avoid interference, assign a unique PAN setting to each wireless network in a building. Using a unique PAN setting is particularly important if you have PANs on adjacent floors of a building. Do not use the same PAN OFFSET on multiple wireless networks in a building, even if the PANs do not overlap.
3. At each Smart Equipment controller, set the MS/TP address as described in the job plans.
4. Connect the ZFR Pro Router to the Smart Equipment controller as shown in Figure 2.
