ZFR1800 Series Wireless Field Bus System Technical Bulletin 33
3. Set the WRZ Sensor DIP switches as shown in Table 5.
4. Verify that the factory calibration jumper is installed. If the jumper is missing,
temperature readings report as unreliable values.
5. Install two AA alkaline batteries (supplied) into the battery compartment on
the back of the sensor. Ensure that you install the batteries in the proper
polarity.
6. Secure the sensor to its mounting base. Repeat these steps for each additional
zone.
Commissioning the ZFR1800 Series Wireless Field Bus System
Once a ZFR1800 Series System has been planned and installed according to the
guidelines in Designing and Planning the ZFR1800 Series Wireless Field Bus
System and Installing the ZFR1800 Series Wireless Field Bus System, use these
steps to commission the system.
1. Power the system and verify communications in the ZFR1800 Series Wireless
Field Bus System using the Signal Strength (ZFR1810 Coordinator) or Status
(ZFR1811 Router/Repeater) LEDs.
a. Remove the ZFR1810 Coordinator from the field bus before starting the
wireless network and verifying wireless communications.
b. Power up the ZFR1810 Coordinator. See Powering the ZFR1810
Coordinator.
c. Power up the ZFR1811 Routers/Repeaters. See Powering the ZFR1811
Router and WEFC and Powering the ZFR1811 Repeater.
d. Do not power up the WRZ sensors.
Table 5: Configuring WRZ Sensor DIP Switches
DIP Switch Setting
Mode Mesh
Zone Set according to application requirements.
Transmit Level 10 mW
MS/TP Address Match the MS/TP address of associated field controller
(FEC/IOM/VMA16).
PAN OFFSET Match the PAN OFFSET of associated ZFR1810 Coordinator and ZFR1811
Routers.
Power OFF
IMPORTANT: The PAN OFFSET switch setting must be the same for all the
ZFR1800 Series and WRZ devices on the same wireless mesh network.
IMPORTANT: To avoid interference, assign a unique PAN Offset to each
wireless network in a building. This 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.
