ZFR1800 Series Wireless Field Bus System Technical Bulletin 39
Powering the ZFR1810 Coordinator
The ZFR1810 Coordinator is required to start the ZFR network.
The ZFR1810 Coordinator needs to be powered, but does not need to be connected
to an NAE/NCE. In fact, the NAE/NCE does not need to be present or online when
you install any ZFR1800 Series component but is needed to complete system
commissioning.
1. Apply power to the ZFR1810 Coordinator.
2. Verify that the ZFR1810 Coordinator Signal Strength LED Goes ON. If not,
see Troubleshooting.
3. Verify that the ZFR1810 Coordinator Fault LED Goes OFF. If not, see
Troubleshooting.
Powering the ZFR1811 Router and WEFC
1. Apply power to each WEFC.
2. Verify that if the WEFC has an application downloaded, its Fault LED goes
off. If the Fault LED is on steady, and the WEFC has an application, a
firmware mismatch may exist between the WEFC and the ZFR1811 Router.
Connect to the WEFC with CCT, and correct the firmware mismatch.
3. Verify that the ZFR1811 Router LED is on. If the LED is off, the Router is not
joining the network; see Troubleshooting.
4. Verify that the ZFR1811 Router LED flashes a good or average Signal Strength
indication after 10 seconds (see Table 19 on page 63). If the LED shows poor
signal strength or is not flashing, see Troubleshooting.
5. Verify that the WEFC’s FC/SA Bus LED flashes to show communications (if
the supervisory controller is connected to the ZFR1810 Coordinator). If the
LED is off or on steady, see Troubleshooting.
Powering the ZFR1811 Repeater
1. Apply power.
2. Verify that the ZFR1811 Router LED lights ON. If not, see Troubleshooting.
3. Verify that the ZFR1811 Router LED flashes a Signal Strength Code after
10 seconds. If not, see Troubleshooting
