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

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
