What do all of these light sequences mean?
Understanding the light sequences generated by your sensor is key to understanding its overall health. Below are the various light sequences that your sensor may display.
Healthy Light Sequences
Initialization
Three "magenta" (both the red and blue LEDs) blinks. This is the sequence displayed when the sensor is connected to either a power or data source. This is normal and occurs as the sensor's onboard computer turns on.
Charging
When plugged into a power source, your sensor will initialize and then slowly blink blue. This means your sensor is currently charging.
Fully Charged
When plugged into a power source, your sensor will initialize and then maintain a solid, unblinking blue light. This means your sensor is fully charged.
Projector Turning On
When plugged into a data stream (i.e. an iPad), your sensor will initialize and the square projector will begin emitting an infrared speckle pattern. You can see this as a reddish light. This means your sensor is currently capturing depth.
Unhealthy Light Sequences
Power Fault
When plugged into a power source, your sensor will initialize and then display a slow, red blinking light. This means that your sensor is experiencing some sort of power-related fault. Unfortunately, this cannot be fixed remotely, and sensors displaying a power fault must be sent in for repair or replacement.
Laser Fault
When plugged into a power source, your sensor will initialize and then display a solid red light. This means that the sensor's laser has been disrupted somehow. In most cases, cleaning the glass plate thoroughly, unplugging the sensor, and plugging it back in with sufficient space between the sensor and an object will reset this fault.
The sensor will display this light sequence if the projector is blocked, giving the impression the sensor is faulty. First ensure nothing is directly in front of the projector before assuming defect.
CPU Fault
When plugged into a power source, your sensor will initialize and then display a quickly blinking red light. This means that the sensor's central processing unit has failed. This cannot be fixed remotely, and sensors displaying CPU Faults must be sent in for repair or replacement.
