window limit models
Teach procedures are identical for window-limit and fill-
level control models. Window-limit models function as
shown in the figure on the right, and fill-level control
models function as shown in Figure 5 on page 5. To
readjust minimum or maximum limits, 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 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 for the first limit.
