Proper Use
The WTB 190TL High Grade photoelectric proximity switch is
an optoelectronic sensor and is used for detection of optical,
non-contact detection of objects, animals, and people.
Starting Operation
1
Select switching function;
[Lon]: light-switching; if light received, output (Q) switches.
[don]: dark-switching; if light interrupted, output (Q)
switches;
If required, set a time delay [dLY] (0 to 10 s).

2A 1-point Teach-in with background suppression
(BGS mode); [bgS]
Align the sensor to the background.
Press the [tch] select button in the Teach-in program until
[1Pt] appears in the display. LED yellow lights for a short
time and the [1Pt] display blinks in the display.
Press the Teach-in button.
Position the object. Yellow LED lights. Background is not
detected in a straight line.
If required, external Teach-in (ET) via control line
PNP: Control wire ET to L+,
NPN: Control wire ET to M.
2B Position Teach-in with background suppression
(BGS mode); [bgS]
Align the sensor to the object.
Press the [tch] select button in the Teach-in program until
[Pos] appears in the display. The LED yellow and display
light briefly.
Press the Teach-in button.
Move the object away from the sensor linearly.
Yellow LED lights.
Object is detected dependent on position.
If required, external Teach-in (ET) via control line
PNP: Control wire ET to L+,
NPN: Control wire ET to M.
2C Precise setting:
The taught scanning range can be corrected manually via
the select key.
2D 1-point Teach-in with foreground suppression (FGS mode);
[FgS]
Align the sensor to the background.
Press the [tch] select button in the Teach-in program until
[1Pt] appears in the display. LED yellow lights for a short
time and the [1Pt] display blinks in the display.
Press the Teach-in button.
Position the object. Yellow LED lights.
The object closer to the taught range is hidden (detected).
If required, external Teach-in (ET) via control line
PNP: Control wire ET to L+,
NPN: Control wire ET to M.

Align the sensor to the background.
Press the [tch] select button in the Teach-in program until
[2Pt] appears in the display. LED yellow lights for a short
time and the [2Pt] display blinks in the display.
Press the Teach-in button.
Position the object.
Press the Teach-in button.
The value in the display goes out.
Release the teach in button. LED yellow lights for a short
time, and [2Pt] appears for a short time in the display and
switches to a numeric value.
Remove the object laterally. Yellow LED lights.
The scanning range is between the taught values.
Objects, which are closer or at a greater distance, are
hidden (detected).
If required, external Teach-in (ET) via control line
PNP: Control wire ET to L+,
NPN: Control wire ET to M.
2f Precise setting:
The taught scanning range can be corrected manually via
the select key.

Function check:
Simulate changing the object; check functioning at the
outputs (see diagram: x=scanning distance, y=% of
scanning distance).
If device does not function correctly, repeat startup
procedures (Teach-in).
Maintenance
SICK photoelectric switches do not require any maintenance.
We recommend that you clean the optical surfaces and check
the screw connections and plug-in connections at regular
intervals.
