Phenomena |
Reason |
Solution |
|---|
| 1 |
Node does not send RF to the base station periodically and LED does not blink |
There is no power supply or battery is flat |
Measure the voltage of the battery OR check the installation of the battery OR check the power supply if applicable |
| The configuration sending cycle is incorrect or is accidentally changed |
Check the sending cycle configuration by offline tool |
| Hardware node is defective |
Check with offline tool and/or check visually any burnt mark, disconnection, heat on the hardware. Contact manufacturer for repair or replacement if needed |
| The node is accidentally in black-list of Sigfox operator |
Check with the Sigfox operator |
| The Sigfox base stations at the node location are out of operation |
Check the operation of another node at the same location or check with Sigfox operator about status of the Sigfox base station |
| New objects are added between the sensor and Sigfox base station |
Check and remove the obstruction objects at site |
| 2 |
Node does not send RF to the base station according to the alarm, LED does not blink |
The alarm threshold values are incorrect and/or alarm function is disabled |
Check alarm threshold values and alarm enable on start up message or heartbeat message or parameter update message or on node memory map with offline tool |
| The number of real alarms during 24-hour are greater than daily alarm limit |
Check the configuration for the maximum number of alarms per day on node memory map |
| 3 |
Node does not send RF to the base station when activated by the magnetic switch, LED does not blink |
The magnetic switch has malfunctioned |
Read the status of the magnetic switch via Modbus (when powering or attaching the battery) to see if the magnetic switch is working OR check the magnetic switch visually |
| Magnet key is not in right touching-position on node housing |
Put the correct position for the magnet key on the node housing |
| 4 |
Node has blinked LED when sending RF but the base station cannot receive the data |
The number of sending message during 24-hour are greater than the limit RF packages of uplink per day (max 140 packages/day) |
Check on the base station whether the event message exceeds the number of RF packets |
| 5 |
Node has sent RF but the LED does not blink |
The LED is malfunctioned |
Contact manufacturer for repair or replacement |
| 6 |
The node does not send RF and the RF module is too hot |
Battery is inserted in the wrong direction |
Check battery polarity |
| Working environment of the node is too hot |
Improve ventilation to lower environment temperature |
| Hardware node is defective |
Contact manufacturer for repair or replacement |
| 7 |
RSSI is weak and often loses data |
Distance between Node and Base station is too far |
Check the location of the Sigfox node and relocate it if applicable |
| There are many obstructions between the node and Sigfox base station |
Check and remove the obstruction objects at site or re-locate the position of the node if applicable |
| New objects are added between the sensor and Sigfox base station |
Check and remove the obstruction objects at site |
| There is a problem of Sigfox antenna connection |
Check the antenna connector on the printed circuit board |
| 8 |
The measurement values from the sensor do not change and keep constant values for a long time |
Sensor got failure |
Check the sensor visually or/and with offline tool. Contact manufacturer for repair or replacement if needed |
| Sensor cable is broken |
Check sensor cable. Contact manufacturer for repair of replacement if the cable is broken |
| The sensor connector is not connected firmly |
Check sensor connector and contact manufacture for repair of replacement if the connector is broken |
| Some sensor measurement settings such as CONSTANT_A, CONSTANT_B, LOW_CUT, HIGH_CUT are misconfigured |
Check and correct right sensor measurement configurations |
