Sensor adjustment (teach-in) via teach input for (I)GS 63B
The following description applies to PNP switching logic!
The device setting is stored in a fail-safe way. A reconfiguration following power failure 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 illuminates and the warning output is activated if a teaching 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 teach)
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. 3 s
