If you have a problem with using the transmitter, check the following tables before contacting Vaisala. If the problem you have is not listed in the tables, or if the proposed solution does not fix the problem, contact Vaisala technical support.
If you suspect that the problem is with the probes connected to the transmitter, you can also check the probe diagnostics and status with the Insight software and Modbus status registers. For probe-specific register information, see the connected probe's Modbus documentation.
| Problem: A power outage occurred. | |
|---|---|
| Possible cause: | Solution: |
|
Wait for the transmitter to power up again. This will take some minutes. When the transmitter powers up, it will continue to show measurements just like before the power outage. To access the web interface again:
|
|
| Problem: You cannot access the web interface login page. | |
|---|---|
| Possible cause: | Solution: |
| If the transmitter's IP address is assigned via DHCP, the IP address may have changed, for example, because the transmitter has been restarted. |
|
| If the transmitter is using a static IP address, there may be something wrong with the static network settings. | Check the static network settings on the touchscreen.
|
| The Ethernet cable may be disconnected from the transmitter. |
|
| Problem: There is no Modbus TCP/IP connection. | |
|---|---|
| Possible cause: | Solution: |
| Check the possible causes for the web interface login page problem above. | Check the solutions for the web interface login page problem above. |
| The Modbus off/on setting may be off. | Make sure that Modbus off/on is set on.
|
| Problem: Logging in to the web interface fails. | |
|---|---|
| Possible cause: | Solution: |
| The transmitter's time has not been set correctly. Some browsers do not accept valid browser sessions if the transmitter's time is significantly different from the browser's time. | Set the transmitter's time on the touchscreen so that browsers
will be able to create a valid browser session.
|
| You have forgotten your web interface password. | Restore factory default settings and reconnect to the web interface. When you reconnect, you will be prompted to give the activation code and create new users and passwords. |
| Problem: The web interface does not show the same contents as the touchscreen display. | |
|---|---|
| Possible cause: | Solution: |
| You have changed a setting on the touchscreen, but the change is not shown in the web interface before you refresh the web page. | Refresh the web page. |
| Problem: There is no measurement data from the connected probe. | |
|---|---|
| Possible cause: | Solution: |
| The probe may be disconnected from the transmitter. |
|
| The probe sensor may be faulty. | |
| Problem: Analog input is not available. | |
|---|---|
| Possible cause: | Solution: |
| You have not updated your transmitter's software. | Ensure you have updated to a software version that supports analog input. |
| Problem: Analog input shows incorrect values. | |
|---|---|
| Possible cause: | Solution: |
| If you have an external power source, the ground potential may have differences. | Use probe 2 connection terminal as power source. |
| Problem: Analog input is not showing any values. | |
|---|---|
| Possible cause: | Solution: |
| Analog input is wired incorrectly. | Check analog input wiring. |
| Analog input powering is not on. | If you are powering your analog input device through the transmitter, make sure analog input powering is on. |
