NOTE TIP:
For some applications (e.g., when switching errors arise due to reflections), we recom‐
mend slightly misaligning the sender and receiver or significantly reducing the oper‐
ating reserve. The WSE26 can suppress switching errors under these conditions by
means of a teach-in (via IO-Link or using the Teach-in button on the housing). This
reduces the operating reserve at the same time.
