▊	Error code description

If there is an error code not listed in the table below, please contact our technical support.

serial number	format	meaning	debugging
1	@E203	Wrong command or parameter	Check input instructions, parameters and communication settings.
2	@E220	Communication error	Check and eliminate electromagnetic interference around sensors and communication lines.
3	@E234	no to scale	Adjust the distance of the measured target to make it within the measuring range.
4	@E252	The temperature is too high	Reduce the ambient temperature. If an error occurs at room temperature, please contact our technical support
5	@E253	The temperature is too low.	Raise the ambient temperature. For sensors with heating function, wait for the heating temperature to rise. If an error occurs at room temperature, please contact our technical support
6	@E255	The received signal is too weak	Improve the reflectivity of the measured target.
7	@E256	The received signal is too strong	Reduce the reflectivity of the measured target.
8	@E257	The background light is too noisy	Eliminate the clutter of background light
9	@E260	There are multiple targets in the measurement, so it is impossible to measure the distance.	Determine the distance of the measured target and eliminate the phenomenon of target distance jump.
10	@E289	Contact our technical support.	/

▊	Sensor indicator description

The sensor status and PROFINET interface status are displayed by LED lights as described in the following table.

LED	explain	Possible cause of abnormality	debugging
Port2	PROFINET interface 2 LED lights green: normal operation LED off: the connection is disconnected.	The device did not shake hands with the master station. The sensor is damaged.	Contact our technical support.
Port1	PROFINET interface 1 LED lights green: normal operation LED off: the connection is disconnected.	The device did not shake hands with the master station. The sensor is damaged.	Contact our technical support.
Power(Error)	Sensor status The LED lights green: the sensor is normal. The LED is red: the sensor is abnormal.	Not running. The sensor is damaged.	Check the operating voltage. Check the corresponding error code and eliminate the exception as instructed. Contact our technical support.
