Sensor adjustment (Teach-In) via teach input for GS 61/… (with Teach)
The following description applies to PNP switching logic!
The device setting is stored in a fail-safe way. A reconfiguration following voltage interruption or switch-off is thus not required.
Line teach while label tape is passing through
Preparation: Insert the label tape in the correct position in the sensor (align the middle of the tape to the sensor marking).
The red LED lights if a teach error occurs (e.g. the label cannot be reliably detected due to insufficient signals).
Regardless of the state, the green LED is on when the teach event is terminated, the yellow LED indicates the current switching
state.
Line teach if the label tape cannot be advanced (static teaching)
Preparation: Remove one or more labels from the base material and place this blank area in the sensor. The label tape must now
not be advanced further.
The process is identical to the line teach with moving label tape.

Activation of the teach-in:
Action starts with the falling edge:
t
Teach
= 1100 … 1900ms
The rising edge starts the teach event. The green and yellow
LEDs flash alternately 3x per second as long as the signal is
high.
Advance the label tape so that several label gaps pass the
sensor, thereby allowing the teach values to be determined.
The teach event is concluded with the falling
edge.
50ms after the falling edge, the sensor returns to
normal operation.
The teach button is enabled again after max. 3s.
