Concept of operation

KT5-2 Display, Teach-in static

Note

The bar display visualizes the detection reliability during teach-in. The more LEDs that illuminate, the better the teach-in:

1 LED illuminates = operation not reliable – contrast difference too low

≤ 4 LEDs illuminate = operation OK – sufficient contrast difference

> 4 LEDs illuminate = reliable operation – high contrast difference

Example

Turn rotary switch to “Teach”

position. Press and hold

teach-in button > 1 s.

Red emitted light and yellow

LED flash.

1. Position mark

Press and hold teach-in button

> 1 s.

Yellow LED goes out.

Optimum emitted light is selected.

Fine adjustment possible using

the “+”/“–” buttons.

Dark mark, small deflection

Light background, large deflection

2. Position background

Switching characteristics

The optimum emitted light is selected automatically.

Light/dark setting is defined using teach-in sequence.

The switching threshold is set in the center between the background and the mark.

Teach-in can also be performed using an external control signal.
