For Your Safety 2.1 Use for Intended Purpose The product is based on the following functional principle: Through-Beam Sensors The transmitter and receiver in through-beam sensors are integrated in separate housings. The output switches if the light beam is interrupted. The function of the transmitter and receiver can be tested with a test input. Through-beam sensors are available with laser light, red light or infrared light. The fine laser beam creates a small spot of light, which can be used to reliably detect even the smallest parts. Their good visibility facilitates easy adjustment and commissioning, even at great distances. In the case of some laser through-beam sensors, the focus is adjustable. Aligning through-beam sensors with red light is very easy thanks to the visible light spot. This product can be used in the following industry sectors: • Special machinery manufacturing • Consumer goods industry • Heavy machinery manufacturing • Paper industry • Logistics • Electronics industry • Automotive industry • Glass industry • Food industry • Steel industry • Packaging industry • Aviation industry • Pharmaceuticals industry • Chemicals industry • Plastics industry • Alternative energy • Woodworking industry • Raw materials extraction 2.2 Use for Other than the Intended Purpose • Not a safety component in accordance with 2006/42/EC (Machinery Directive) • The product is not suitable for use in potentially explosive atmospheres. • The product may only be used with accessories supplied or approved by wenglor, or combined with approved products. A list of approved accessories and combination products can be accessed at www.wenglor.com on the product detail page. DANGER!

DANGER! Risk of personal injury or property damage in case of non-compliance! The system’s safety function is disabled. Personal injury and damage to equipment. • Required action as specified in case of fault. 6. Settings • Emitter and receiver must be securely mounted. • Turn the receivers potentiometer all the way up (right stop). • Turn back the potentiometer to its left stop. • Turn the potentiometer up, until the output is activated. • Keep on turning the potentiometer about 5° in order to increase the switching reserve. • Place the object to be scanned within the light barrier and check for correct functioning. Test Input If the test input is open or connected with minus, the barrier works normally. If it is connected with plus, the sensor switches off. The barrier is tested via this changing of the switching status. 7. IO-Link Further settings are possible via the IO-Link interface.
