ZFR1811 Wireless Field Bus Router Installation Instructions

Troubleshooting
Use the Status Light-Emitting Diode (LED) (see
Figure 1) along with the information in Table 3 to
troubleshoot the ZFR1811 Router.
Wireless Signal Strength
A wireless signal strength indication LED displays the
reception strength of the transmissions between the
ZFR1810 Coordinators, ZFR1811 Routers, and the
WRZ Series Sensors. This LED helps determine the
network connectivity status when selecting locations for
the devices during system installation.
Wireless transmissions between ZFR1810
Coordinators and ZFR1811 Routers occur as needed.
Wireless transmissions between ZFR1811 Routers and
WRZ Sensors occur approximately every 60 seconds
or when the occupancy button on the WRZ Sensor is
pressed. Refer to the
WRZ Series Wireless Room
Temperature Sensors Installation Instructions (Part No.
24-10332-2)
for more information.
Approximately once every 10 seconds, the Signal
Strength LED flashes to indicate the strength of the
signal received from neighboring devices. See Table 3.
Note:
The Signal Strength LEDs on all the ZFR1811
routers in a network extinguish after approximately
2 hours of normal operation, making the ZFR1811 less
distracting when installed in an open area. To re-enable
the ZFR1811 LEDs for troubleshooting purposes,
perform a scan using the ZFR Checkout Tool (ZCT).
Alternatively, push the Network Optimize/Reform Push
Button on the ZFR1810 coordinator for 0-5 seconds.
Note that if you press this button more than 5 seconds
a Network Optimize or Reform is initiated.
Refer to the
ZFR1800 Series Wireless Field Bus
System Technical Bulletin (LIT-12011295)
for more
information on determining the signal strength between
ZFR1800 Series devices in your application.
