Proper Use

This wenglor product has to be used according to the following functional principle:
Reflex Sensors with Background Suppression
Reflex sensors with background suppression analyze the light reflected from objects. As these sensors work according to the principle of angular measurement, the color, shape and surface characteristics of the object have almost no influence on the detection range. Even dark objects can be reliably detected against a bright background. The output is switched as soon as an object passes the selected range.

Safety Precautions

This operating instruction is part of the product and must be kept during its entire service life.
Read this operating instruction carefully before using the product.
Installation, start-up and maintenance of this product has only to be carried out by trained personnel.
Tampering with or modifying the product is not permissible.
Protect the product against contamination during start-up.
Not a safety component in accordance with the EU Machinery Directive.

Distance	50 mm	100 mm	150 mm
Light spot Ø	1,2 mm	< 0,5 mm	1,5 mm

Switching distance

The minimum range is equal to the range × 0,9 (at an ambient temperature of 25°C). All specified switching distances apply to white, matt Kodak paper, 200 grams per square meter, with a surface area of 40×40 cm with light striking at a 90° angle.

Mounting instructions

During operation of the sensors, the corresponding electrical and mechanical regulations, as well as safety regulations must be observed. The sensor must be protected from mechanical impact.

Settings

Foreground Teach-In

Mount and adjust the Sensor.
Align the spot to the OBJECT.
Press and hold the Teach-In key until the LED blinks (approx. 1 second), and then release.
- Switching distance is set to directly behind the surface of the object.
Test the switching function.

Background Teach-In

Mount and adjust the sensor.
Align the spot to the BACK- GROUND, or to empty space.
Press and hold the Teach-In key until the LED blinks (approx. 1 second), and then release.
- Switching distance is set to directly in front of the background, or to Sn max. in the event of Teach- In to empty space (see "Teach-In to Empty Space").
Test the switching function.

Teach-In to Empty Space
In this case it is advisable to perform Teach-In at a distance of somewhat more than nominal sensing distance (150 mm). An object, such as a sheet of paper, is positioned approximately 160 mm in front of the Sensor to this end, and the Teach key is activated. The Sensor adjusts itself to a sensing distance of approximately 155 mm (Background-Teach-In).

Selecting a Teach-In Mode

Press and hold the Teach-In key for at least 10 seconds, until the LED switches from rapid to slow blinking

Blinking	Normally closed/ Normally open	TEACH Modus
1×	NO	Background Teach-In
2×	NO	Foreground Teach-In*
3×		Background Teach-In
4×	NC	Foreground Teach-In

* preset configuration

Press the key briefly to advance to the next Teach-In mode
After the key has not been activated for 15 seconds, the sensor returns automatically to the normal display mode
Repeat Teach-In process corresponding to setup instructions

Disabling
If the external Teach-In input is permanently set to +Ub, the sensor is protected against inadvertent misalignment.

External Teach-In
The sensor is equipped with an input for external Teach-In (pin 2). If a positive voltage pulse is applied to this input, sensing distance is adjusted automatically.

Additional Functions for activation via the interface: On-/Off-Delay
Either pull-in or release delay can be activated at the Sensor via the interface. Delay time can be adjusted. The A232 adapter box is required in order to be able to connect the Sensor to Demo software available at: www.wenglor.com

warning Attention!
The sensing distance can be set by pressing the Teach-In key. However, if a sharp object is used to this end, for example a needle or tweezers, damage to the rubber membrane which covers the key may result. A maximum pressing force of 20 N may not be exceeded.
