ZFR1800 Series Wireless Field Bus System Technical Bulletin 35
• If a ZFR1810 Coordinator shows poor signal strength, you may improve
the signal strength by moving the device’s antenna a couple of inches in
either horizontal direction.
If you cannot complete Step 1, review the information in Location and
Estimating Guidelines and Designing and Planning the ZFR1800 Series
Wireless Field Bus System.
For more information, refer to the following documents:
• ZFR1810 Wireless Field Bus Coordinator Installation Instructions
(Part No. 24-10325-2)
• ZFR1811 Wireless Field Bus Router Installation Instructions,
(Part No. 24-10325-10)
2. Use the ZFR Checkout Tool (ZCT) to perform a scan of the mesh.
a. Ensure all controllers and repeaters are communicating on the ZFR system
mesh.
b. Select the Status Tab and ensure everything in the Device Status column is
green.
c. Select the Routing Tab and verify there are no controllers requiring more
than 5 hops to communicate with the ZFR1810 coordinator.
d. If new devices are failing to join the network, or if the ZCT indicates
abandoned children or duplicate short addresses, you may benefit from
reforming the network using the Commands > Reform Network menu
item. Devices should come online in 5 to 15 minutes. Be careful with
network reforms. If all the devices are not online, a reform can make things
worse, particularly if done too frequently. A good practice during startup
commissioning is to reform nightly as you leave the site, which allows the
mesh to stabilize by morning.
Note: Disconnect the NAE from the MSTP network before initiating a
reform. The extra communication traffic that the NAE attempts while
the ZFR PAN is in this mode can be very disruptive, causing the reform
to take longer or fail.
Note: The Signal Strength LED on the ZFR1811 Routers flashes rapidly for
5 minutes when the Network Reform command is received. See
Table 7.
For more information on the ZCT, refer to the Using the ZFR Checkout Tool
(ZCT) chapter of the Controller Tool Help (LIT-12011147).
3. Use the Controller Configuration Tool (CCT) to check addressing and versions
of all wirelessly enabled devices on the trunk.
a. Use the MS-BTCVT-0 Wireless Commissioning Converter at the FC/SA
Out Bus connection of the coordinator.
Note: Use a six-wire phone extension cable (less than 100 ft long) to place the
Wireless Commissioning Converter in a convenient location.
