IGSU 14E standard functions During operation the sensor is always in this function. The sensor detects label gaps with high precision and speed. This is indicated by the yellow OUT LED and the switching output. ON LED Constantly ON when operating voltage is applied. green OUT LED Indicates the switching signal.

easy Teach while the label tape is passing through (dynamic) During the easy Teach process, a two-point calibration is performed on the carrier and the label. NOTICE With respect to detection reliability, the easy Teach process is gener- ally to be preferred over the static teach process. Preparation: Insert label tape into the sensor.

Sensor adjustment via teach input (pin 5) Teach-in To teach, a teach signal is applied to the teach input (pin 5). The duration of the teach signal (low level on the teach input) determines the teach-in function. NOTICE Before a low level is applied for teaching-in functions, a high level must be applied for at least 20 ms.

Locking the buttons via the teach input Manual locking of the buttons on the device is only suitable for protecting against tampering to a limited extent since locking can be canceled using the correspond- ing button combination. For this reason, it is also possible to lock the buttons via the teach input (pin 5).
