LEDs

The detector has four LEDs embedded in the top cap. The orientation of the LEDs relative to the connector depends on the detector series. Some detectors are mounted with the fastening wings down such as the MS-2000, and some are mounted with the fastening wings up such as the MS-350 or the MS-1000. The position described below is with the connector oriented below the LEDs.

Name	Color	Function
PWR	Green	Input voltage is ok and in the right input range
	Red	Input voltage is too low
	Red blinking	Blinking at 1 hz means that the input power could not be measured
	Blue	Input voltage is too high, possibly damaging the internal electronics
	Purple	Input voltage has large fluctuations, please check the power supply
ETH	Green	Ethernet cable is connected
	Blue	The device is connected to the internal through an internal 4g modem and simcard
SCN	Yellow	A raw spectrum is collected.
	Green	A raw spectrum is stabilized, analysed and stored.
AUX	Yellow	A PTH reading is collected and stored
	Green	A GPS reading is collected and stored
	Blue	A auxiliary reading is collected (possibly external sensor)

If the SCN and AUX LEDs blink in red this means that the internal storage is almost full. The threshold percentage for this signal as well as the action taken when the device is full can be set on the settings page on the webserver. The default action when all storage space is taken is to overwrite the oldest data.
