Figure 6. Using the Auto-Window feature for programming
Teach procedures are identical for window-limit and fill-
level control models. Teaching the same limit twice
automatically centers a 200 mm window on the taught
position. To readjust the sensing midpoint, repeat the teach
procedure.
A button click is defined as: 0.04 s. ≤ Click ≤ 0.8 s.
1. Enter programming mode.
Action Result
Push and hold TEACH push button for 2 seconds. Output LED turns solid red and the sensor waits for first limit.
2. Teach the first limit.
Action
Result
Position the target at the desired midpoint for the sensing
window.
Click the TEACH button. Output LED changes to flashing red
3. Teach the second limit.
Action
Result
Without moving the target, click the button again. The sensor stores sensing window and the Output LED turns solid
amber. The sensor returns to Run mode.
