Micro CAN module LED functionality
Multi color status LED Function on the micro CAN
|4 flashes||The LED will flash 4 times every 15 seconds (and when booting) to indicate status:
Flash 1: Indicates CAN bus status (BLUE: Communication with CAN Control Module OK || RED: No communication detected)
Flash 2: Indicates the status of the external combined temperature/humidity I2C sensor (GREEN: External I2C temp/humidity sensor OK and used || RED: No external I2C temp/humidity sensor found)
Flash 3: Indicates the status of the temperature sensor (DS1820) connected on the first output OR the status of the external temperature/humidity sensor (GREEN: sensor OK || RED: Error or no sensor connected)
Flash 4: Indicates the status of the temperature sensor (DS1820) connected on the second output.
|GREEN flash||When a switch is pressed, the LED flashes GREEN|
|GREEN dim/on/off||When the instruction "input indicate" is used and an input of this micro CAN is selected|
|BLUE dim/on/off||When the instruction "sensor indicate" is used and a sensor (onboard sensor, temperature/humidity sensor or DS1820 on Output 1) of this micro CAN is selected|
|PINK dim/on/off||When the instruction "sensor indicate" is used and a sensor (DS1820 on Output 2) of this micro CAN is selected|
|RED flash||Short circuit or overcurrent is detected on the 5VDC output|
- It can take up to 2 minutes before a connected sensor is found.
- You can connect either a combined Temp/humidity I2C sensor, or 1 or 2 DS1820 sensors which means that LED indication is green for the I2C sensor or green for the DS1820.
