# Self-Diagnosis and Error Codes ORCA Level Sensors include the following diagnosis features: - **Self-Test**: When triggered by the respective IO-Link System Command, the RGB LED is checked electrically. - **Monitoring** of Supply and internal Voltages and MCU Temperature - **Overload Detection** on digital and analog outputs Detected errors are indicated via IO-Link Events and/or in the **Error Code** IO-Link Parameter, as well as by blinking patterns of the LED. ## Error Codes

Blink Code	IO-Link Error Code	Description
1	0x0001	Internal error
2	0x0002	Error with intermediate voltage
4	0x0008	Supply voltage overrun / underrun
8	0x0080	Parameter memory error
9	0x0100	Parameter error
12	0x0800	LED error
13	0x1000	Overload on digital output
–	0x2000	Overload on analog output
15	0x4000	Temperature overrun
