Enabling/disabling additional functions
Available special functions (dependent on device model)
12% – switching threshold close to the mark
This function is suitable for applications in which the background exhibits high inhomogeneity. It is operated via the
M
button
(> 12 s). The shift of the switching threshold is effective immediately, independent of the teach event.
The LED is also activated if a switching threshold position other than 50% was selected via IO-Link.
L/D – Light/dark switching
The function inverts the switching logic of the switching outputs. It is operated via the
B
button (> 12 s).
TRA – Tracking function
This function increases the process stability of the contrast sensor. Even if the mark changes slightly in color or contrast, the
sensor operates with optimum switching threshold since the threshold is automatically readjusted during the process. It is oper-
ated via the
B
button (> 12 s).
Press the button assigned to the additional
function for longer than 12 s.
Release the button.
To change the setting again, push the button
again for longer than 12 s and release.
Only the green LED flashes.
Switching threshold in center between mark
and background.
Switching threshold is near the mark.
OUT1
(Pin 4): high signal on mark.
OUT2
(Pin 2): low signal on mark.
OUT1
(Pin 4): low signal on mark.
OUT2
(Pin 2): high signal on mark.
Tracking function inactive.
