ALC function

The 

ALC function can be manually deactivated and activated.

7

Ä

Press the minus button (-) until the green ON LED and the yellow OUT LED
flash synchronously.

Ä

Release the minus button (-).

NOTICE

The manual deactivation/activation of the 

ALC function is stored in

non-volatile memory in the sensor.

easyTune – Manual fine tuning of the switching threshold

With homogeneous label material, the signal in the gap between two labels is
much larger compared to the signal on the label. 
For the taught switching threshold, there is a high function reserve in both the gap
as well as on the label, and the sensor functions reliably.
To achieve a better function reserve, it can be advantageous to change the taught
switching threshold, especially for inhomogeneous label material.
The sensitivity of the sensor and, thus, the switching threshold can be adjusted
with the 

easyTune function, which is in principle comparable to a potentiometer.

NOTICE

Use of the 

easyTune function temporarily deactivates the ALC func-

tion!

The 

ALC function is reactivated after teaching again.

8

The sensitivity of the sensor can be adjusted by pressing the teach button (+) or
the minus button (-).

Increase sensitivity:

Ä

Briefly press the teach button (+).

ð

A single flash of the green ON LED confirms button actuation.

Reduce sensitivity:

Ä

Briefly press the minus button (-).

ð

A single flash of the yellow OUT LED confirms button actuation.
