Chapter 4 Mounting Chapter 4 Mounting This chapter describes the preparation and completion of the mounting of the SC300 safety camera system.
Chapter 4 Mounting Protective field dimensions allowed at a resolution of 24 mm The lengths of the sides of a protective field monitored must not be shorter than 0.40 m and not longer than 1.20 m. Longer side of the protective field Shorter side of the protective field Minimum Maximum ≥0.40 m … <0.60 m = shorter side 2 × shorter side ≥0.60 m … ≤1.20 m = shorter side 1.
Chapter 4 Mounting Safety distance S (Ds) Protective field height Hazardous point All-round reflective tape Figure 9 - Safety distance from the hazardous point ATTENTION If the protective field is at an angle, pay special attention to the safety distance. S (D s) Ensure the necessary safety distance between the access point and the hazardous point is met at all parts of the protective field at an angle.
Chapter 4 Mounting K= 2000 mm/s Definition and value as per prEN ISO 13 855, derived from data on the approach speed of the body or parts of the body T= Stopping/run-down time of the entire system in [s] Stopping/run-down time of the entire system = Stopping/run-down time of the machine + response time of the protective device after light path interruption d= Detection capability (resolution) of the protective device in [mm] The reach/approach speed is already included in the calculation formula.
Chapter 4 Mounting Safety distance if OSHA and ANSI are applicable If OSHA and ANSI are applicable, the safety distance depends on: • Stopping/run-down time of the machine or system (The stopping/run-down time is shown in the machine documentation or must be determined by taking a measurement.
Chapter 4 Mounting Avoiding unmonitored areas ATTENTION ATTENTION Provide separate protection for unmonitored areas. During the installation of the SC300 safety sensor system, incorrect mounting or mutual interference between several systems may result in areas that are not monitored and through which an operator could reach the hazardous point. Protect unmonitored areas using mechanical guards. Note the following warning and precautions to prevent unmonitored areas. Avoid mounting in a frame.
Chapter 4 ATTENTION Mounting During mounting, please observe the maximum protective field width. If, during mounting, the maximum protective field width for one or two safety sensor systems is exceeded, the safety sensor will not see the reflective tape opposite. As a result an unmonitored area will be produced. The operator is at risk.
Chapter 4 Mounting Steps for mounting the safety camera system ATTENTION Special features to note during mounting: Avoid unmonitored areas as described in the previous section. Always mount the safety sensor on a flat surface. Always mount the safety sensor on a metal surface and ensure good mechanical contact. In this way you will ensure adequate heat dissipation from the device. During mounting, ensure that safety sensor and reflective tape are aligned correctly.
Chapter 4 Mounting Note You will find other mounting options on the example application at www.rockwellautomation.com. Mounting on a frame Notes Always mount the camera with at least two screws and use the fastening openings on two opposite sides of the housing. Secure the two mounting screws against unintentional loosening.
Chapter 4 Mounting Mounting in a frame SC300 R Figure 15 - Mounting in a frame Notes Always mount the camera with at least two screws and use the fastening openings on two opposite sides of the housing. Secure the two fixing screws against unintentional loosening. Always use washers under the screws (Figure 15). Use sliding nuts suitable for the profile system employed for mounting the camera.
Chapter 4 Mounting Figure 16 - Correct arrangement of the reflective tapes at joints If damage to the reflective tape is to be expected due to the application, e.g. because heavy or sharp-edged objects are pushed over the working area, you should use one of the following possible mounting methods: – Mount the camera in the bottom of the frame. – Mount the camera lower than the contact surface in front of the frame.
