PRECAUTIONS FOR PROPER USE
Teaching
• The threshold values can be set by normal mode (2-level teaching, limit teaching
• This is the method of setting the threshold value by teaching two levels, corresponding to
Notes: 1) Do not move or bend the fiber cable after the sensitivity setting. Detection may become unstable.
• Full-auto teaching is used when it is desired to set the threshold value
