Sensor Does Not Communicate with WCI

Problem and Code
Sensor is not associated with UC (E1)
Sensor has not joined the network(E2)
Sensor drains battery current during sleep (E3)
Internal failure (E7)
Wrong sensor address (E8)
Duplicate sensor (E9)

No Communication

Problem
Power loss
Signal obstruction
One of the devices is outside of radio range
Incorrect power-up sequence

Slow Communication

Problem
Duplicate unit controller BACnet Device IDs.
BAS-SVX40K-EN
• Verify that the unit controller and WCI firmware are up to date.
• The configured address in the sensor does not match the dials of a UC for any WCI in the same
wireless network. Re-associate the sensor with the WCI by correcting the UC address in the sensor.

• Verify that the network is open.
• Normal for sensor configured with GRP-NET 0-0.
• Verify that the sensor has the correct group (GRP) and network (NET) addresses.
• Verify that the sensor is within radio range.
• If the sensor has previously joined the network, verify that WCIs in range are powered up. Force the
sensor to associate by pressing the UP arrow on WCS-SO/SCO
button twice on all other WCSs. Otherwise, set the correct GRP and NET addresses and open the
wireless network to allow the sensor to join.
If the error persists and batteries drain prematurely, the sensor may have defective components and
need to be replaced.
Sensor display fails to communicate with the radio. Replace the sensor.
The configured sensor address does not match the sensor address that is expected by the UC. Use
Tracer TU to configure the UC for the quantity of sensors it should accept, if more than one. Incorrect
number of sensors configured in the UC. Use Tracer TU to correct.
Another sensor with the same configured UC address and sensor address is already associated with the
UC. Resolve the duplication. This may involve waiting (up to 34 minutes) for the UC to forget the address
of a failed sensor.
Communication will automatically be restored when power is restored.
Routes in the mesh network are updated every 10–30 seconds.
Move network components to within radio range or break up networks to make smaller networks so that
all components are within radio range. Alternatively, you can add a repeater to extend the radio range.
Cycle power on the controller or Tracer SC connected to the WCI.
Make sure that every device on the network has a unique BACnet Device ID. Refer to the current version
of BAS-SVX51*-EN, BACnet MS/TP Wiring and Link Performance Best Practices and Troubleshooting
Guide.
