We received two arc protection I/O unit (VAM12LSE), both with same error.
When we turned on the I/O units with 24VDC power supply, the error indicator is turned on and (unlike other sensor inputs) LED of sensor input no. 4 is blinking, without any arc sensor connection to it.
In addition, if we connect an arc sensor to input 4, the corresponding LED is turned off.
in the following link you can find the corresponding recorded movie.
can anyone help us to find the problem?
