Commissioning For commissioning, a person is considered competent when he/she has the expertise and experience in the relevant field and is sufficiently familiar with the application of the protective device on the machine that he/she can assess its operational safety status. Operation and maintenance For operation and maintenance, a person is considered co ...

Overview The C4-RD safety light curtain is an electro-sensitive protective device (ESPE) consisting of a sender and receiver. A series of parallel infrared light beams forms a protective field between sender and receiver that protects the hazardous area (hazardous point, access, and hazardous area protection). When one or more beams are completely interrupted, the safety light curtain reports the interruption in the light path to the secure output signal switching devices (OSSDs) by a signal change. The machine or its control must safely analyze the signals (for example using a safe control or safety rel ...

DANGER Hazard due to lack of effectiveness of the protective device Persons and parts of the body to be protected may not be recognized in case of non-observance. b Conduct a risk assessment and check whether additional protective measures are required. b Comply with the applicable national regulations derived from the application (e.g., work safety regulations, safety rules, or other relevant safety guidelines). b Do not combine the components of the safety light curtain with components from other safety light curtains. b Apart from for the procedures described in this document, the components of the ...

Persons and parts of the body to be protected may not be recognized in case of non-observance. b Make sure that the following construction requirements are met so that the safety light curtain can fulfill its protective function. ° Sender and receiver must be arranged such that persons or parts of the body are reliably detected when they enter the hazardous area. ° Reaching under, over, and around as well as moving the safety light curtain must be prevented. ° Check whether additional safety measures (e.g. restart interlocking) are nec‐ essary when it is poss ...

The calculation of the minimum distance is based on international or national stand‐ ards and statutory requirements applicable at the place of installation of the machine. If the minimum distance is calculated according to ISO 13855, then it depends on the following points: • Machine stopping time (time interval between triggering the sensor function and the end of the machine’s dangerous state) • Response time of the protective device • Reach or approach speed of the person • Resolution (detection capability) of the safety light curtain • Type of approach: orthogonal (at right a ...

If the new value S is > 500 mm, then use the newly determined value as the minimum distance. 5. If the new value S is ≤ 500 mm, then use 500 mm. !

over. Left: Protective field that cannot be reached over. Right: Protective field that can be reached over. 4.3.3 Minimum distance to reflective surfaces Overview The light beams from the sender may be deflected by reflective surfaces and dispersive media. This may prevent an object from being detected. Therefore, all reflective surfaces and objects (e.g. material bins, machine table, etc.) must maintain a minimum distance (a) from the protective field. This minimum dis‐ tance (a) must be maintained on all sides of the protective field. This applies in ho ...

The minimum distance can be determined as follows: b Determine the distance between sender and receiver D in meters (m). b Read the minimum distance a in millimeters (mm) in the graph or calculate using the respective formula to determine the minimum distance to reflective surfaces: 500 400 300 200 100 a/mm 10 11 12 D/m 1 2 3 4 5 6 7 8 9 Figure 11: Graph of minimum distance from reflective surfaces Table 2: Formula for calculating the minimum distance from reflective surfaces Distance (D) between sender and receiver in m Calculation of the minimum distance (a) from reflective surfaces in mm D ≤ 3 ...
