Troubleshooting
When the device is being calibrated or when the device is operational, in exceptional cases certain steps in the
process might not succeed.
When the device is successfully connected to the network and problems occur, the troubleshooting should be
performed on the network side. The device is working correctly.
Time-out
A time-out is a time limit for the completion of a certain process step. This can occur in three states:
• when a user action is required (blue LED)
• when the device is connecting to the network (blinking yellow LED)
• when the device is processing (solid yellow LED)
If a time-out occurs, the device will reset the calibration.
Blue LED
The blue LED will stay on for a maximum of 30 seconds; after this time limit, the device will reset the calibration.
• Required user action not completed within 30 s → the device resets the calibration
Blinking Yellow LED
A blinking yellow LED will stay active for a maximum of 2 minutes; after this time limit, the device will reset the
calibration.
• Connecting to the network failed → the device resets the calibration
Yellow LED
The yellow LED will stay on for a maximum of 30 seconds; after this time limit, the device will reset the
calibration.
• Sensor reading during calibration not stable → the device resets the calibration
