6 Trouble shooting
6.1 Tank sensor is not visible on PICO
If the tank sensor is not visible in PICO’s menu, check the following:

Is the ST107 properly connected via the SiCOM port to the PICO.

If you are using your own SiCOM cable make sure you are using the right one. See 4.2.1 SiCOM data cable.
6.2 Tank sensor is showing the same liquid level for long time
In case you installed the sensor for the first time, consider checking the following:

Are you using a compatible resistance/voltage tank sensor? Check the requirements in chapter 5 Technical
specifications.

Is the tank sensor properly installed and working?

Is the tank sensor properly connected to the right resistance or voltage input sensor on ST107?

Is the tank sensor calibrated via PICO’s menu? Each tank sensor needs to be calibrated to show the right level. Check
PICO’s manual, how to calibrate a tank sensor.
In case the tank sensor has stopped working, consider checking the following:

Is the tank sensor properly installed and working? In case you are using a floating sensor, it could be stuck.

Consider to recalibrate the tank sensor.
6.3 Tank sensor is showing empty tank
In case you installed the sensor for the first time, consider checking the following:

Is the tank sensor covering the whole tank level? In case you are using a floating sensor, which is to short, it can
happen that the sensor is not detecting any liquid under a specific level.

Consider to recalibrate the tank sensor.
