6. Troubleshooting Guide
Sensor COMM Error
 Verify all SmartWireless® CXT devices have a unique Modbus ID number.
 Verify the Sensor Input PCA and Relay PCA Modbus address are set correctly
 Verify the Radio Module Modbus address is set correctly
Sensor Fault
 Verify if sensor displays any fault. If so, follow sensor trouble shooting notes.
 Verify if sensor cell needs replacement.
Low Battery
 Attach external battery charger
 Verify solar panel (if used) is oriented correctly
Poor Link Quality
 Verify antenna is securely attached to all devices.
 Verify obstructions are eliminated or minimized between SmartWireless® CXT devices and
controller or other CXT devices.
Slow Gas Response
 Some delay in gas response is normal if the network update rate is greater than zero. To increase
response time, reduce the update rate. Reducing the update rate will reduce the battery life for
devices.
SmartWireless® CXT not found during controller Auto Configure
 Verify CXT device set to correct RF Channel
 Verify Radio Module has correct Modbus address
 Verify the Sensor Input PCA and Relay PCA Modbus address are set correctly
 Verify a proper mA load is present on sensor input. Sensor inputs are not detected unless the mA
input is greater than 1.9mA.
