What it means
Fault on one or more plant environmental sensors: irradiance sensor (pyranometer or reference cell), module temperature probe (PT100/PT1000), weather station. Environmental data unavailable or unreliable.
Probable causes
- Sensor wiring broken, oxidized, or with a loose connection.
- Pyranometer out of calibration or dome dirty/damaged.
- PT100 module temperature probe disconnected or with insufficient thermal contact.
- Weather station offline due to power supply or serial communication fault.
Where to start
Identify the faulty sensor: irradiance (pyranometer/reference cell), module temperature (PT100), or weather station. Check the wiring from the sensor to the datalogger analog input. Is the wiring intact?
