Action Result
Position the target for the second limit.
Click the TEACH button. The sensor stores both limits and Output LED turns solid amber.
The sensor returns to Run mode.

Figure 5. Fill-Level Control
The Fill-Level Control mode provides the switching logic required for fill-level, web tensioning control, and similar
applications. In this mode, the output energizes when the target reaches the first sensing window limit, and stays
energized until the target moves to the second limit. The output then de-energizes at the second limit and does not re-
energize until the target moves, again, to the first limit.

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.
