| Problem | Possible cause | Action |
|---|---|---|
| The data collecting system does not receive data. | Improper or loose connections | Check the wiring and tighten the screw terminals. |
| Incorrect messaging settings | Check and correct the messaging settings through the service connection. | |
| Power failure | Make sure that the power supply is connected and operational. | |
| Sensor shaft heating is not working. | Heating power is not connected properly. | Check the wiring and tighten the screw terminals. |
| Heating is not enabled in the transmitter settings. | Check and correct the transmitter settings using the service connection. | |
| The heating power supply has a power failure. | Make sure that the power supply is connected and operational. | |
| MWV message returns a null field (,,) for wind speed or direction reading. | Parameter spdvoltlimit or dirvoltlimit has too high a value and the sensor is considered absent or faulty. | Set a lower value for the parameter. See SETALR. |
| WA25 system returns null fields (,,) or incorrect values. | Parameter spdvoltlimit, dirvoltlimit, or powersave has a wrong value. |
For WA25, set: spdvoltlimit = 0 dirvoltlimit = 0 powersave = 0 |
| Wind vane returns readings with constant deviation from the correct direction. | The cross arm is incorrectly aligned or the offset parameter value is wrong. | Check the alignment. If correct mounting is impossible or inconvenient, correct the alignment with the offset parameter. See SETDIR. |
