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.

PWRGreenInput voltage is ok and in the right input range.

RedInput voltage is too low.

Red blinkingBlinking at 1 hz means that the input power could not be measured.

BlueInput voltage is too high, possibly damaging the internal electronics.

PurpleInput voltage has large fluctuations, please check the power supply.

ETHGreenEthernet cable is connected.

BlueThe sensor has a connection to the internet.

SCNYellowA raw spectrum is collected.

GreenA raw spectrum is stabilized, analyzed, and stored.

AUXYellowA PTH reading is collected and stored.

GreenA GPS reading is collected and stored.

BlueAn auxiliary reading is collected (external sensor).

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