Automatic setting of the switching threshold (2)
• Stationary objects
• Diffuse reflection fibre (FT ...) and through-beam fibre (FE ...)
The unit detects input signals of various intensity in any sequence and
calculates the optimum switching threshold.
1
Press until the row of LEDs flashes.
Place the object into the
detection area.*
2
Press once.
Remove the object.*
3
Press once.
* You can also proceed in reverse order: first setting without the object, then
with the object.
If the setting of the switching threshold is not possible (e.g.
object signal and background signal are about the same), the
row of LEDs flashes after step 3. The unit then passes into the
operating mode with the switching threshold being unchanged.
