easyTune – Manual fine tuning of the switching threshold

With homogeneous web material, the signal on the web is greater than the signal
on the splice. 
For the taught switching threshold, there is a high function reserve, and the sensor
functions reliably.
To achieve a better function reserve, it can be advantageous to change the taught
switching threshold, especially for inhomogeneous web 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.

5

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.

Action

After teaching, the yellow
LED and the switching
output flicker if the splice
is moved through the sen-
sor:
The function reserve on
the splice is too low.

Reduce sensitivity of the
sensor
(upward shift of the
switching threshold)

Repeatedly press the mi-
nus button (-) briefly until
the sensor detects the
splice stably and without
interruption.

In certain cases, a highly
inhomogeneous web ma-
terial can affect the func-
tional reliability. The yel-
low LED and the switch-
ing output flicker if the
blank web is moved
through the sensor with-
out splices: 
The function reserve on
the web is too low.

Increase sensitivity of the
sensor
(downward shift of the
switching threshold)

Repeatedly press the
teach button (+) briefly
until the sensor detects
the transported web ma-
terial without splice stably
and without flickering.
