Chapter 1 About This Document The term “dangerous state” The dangerous state (standard term) of the machine is always shown in the drawings and diagrams of this document as a movement of a machine part. In practical operation, there may be a number of different dangerous states: •...
On safety This chapter deals with your own safety and the safety of the equipment operators. Please read this chapter carefully before working with the SC300 or with the machine protected by the SC300. Qualified safety personnel The SC300 safety camera system must only be installed, commissioned and serviced by qualified safety personnel.
Chapter 2 On safety The device is a Type 3 ESPE (SC300 safety camera) according to EN 61 4961 and IEC/TR 61 4964 and is therefore allowed for use with controls in Category 3 according to EN ISO 138491. The device is suitable for hazardous point protection (hand protection).
• The operating instructions must be made available to the operator of the machine where the SC300 safety camera system is fitted. The machine operator is to be instructed in the use of the device by qualified safety personnel and must be instructed to read the operating instructions.
Protective field Figure 1 - Operating principle of the SC300 The SC300 safety camera system comprises a camera as well as a reflective tape with which the contour to be monitored is defined. The camera monitors the area bounded by its field of view and the reflective tape –...
Figure 5 - Hazardous point protection with two SC300, placement in opposite two SC300, placement at corner directions The SC300 safety camera system operates correctly as a protective device only if the following conditions are met: • The control of the machine must be electrical.
Restart interlock Figure 6 - Outline drawing of the protective operation The SC300 has an internal restart interlock. The dangerous state of the machine () is interrupted on a protective field interruption (), and is not re-enabled ()until the operator presses the reset button.
Reset If you activate the restart interlock on the SC300 (internal) and also realize a restart interlock on the machine (external), then each restart interlock gets its own button.

Avoiding unmonitored areas Provide separate protection for unmonitored areas. ATTENTION 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.
Page 23
Prevent the mutual interference of systems mounted in close ATTENTION proximity. If two SC300 are so arranged that they entirely or partially look at the same reflective tape, the two safety sensors may interfere with each other. This can disrupt the protective function of the system.
During mounting, ensure that safety sensor and reflective tape are aligned correctly. The SC300 accepts a defined lateral tolerance (see “Mounting the reflective tape” on page 24). Take suitable measures to attenuate vibration if the shock requirements are above the values given in the “Data sheet”...
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. ...
Only the longest contiguous section of the reflective tape is taught-in by the SC300. If there are gaps in the reflection, the safety camera system will ignore the shorter section of the reflective tape. Rockwell Automation Publication 10000202762 Ver 01—December 2014...

Principle of operation When the light path on the SC300 safety camera is clear and the input conditions on the GSR DI safety relay module are valid, the system is ready for switch on and waits for an input signal/switch on signal. The system’s corresponding logic path is enabled by pressing and releasing the related restart switch.
Otherwise un-monitored areas may be produced. Ensure the housing markings on the two cameras are aligned. You must synchronize the two SC300 with each other so that they do not interfere with each other (see page 30). Rockwell Automation Publication 10000202762 Ver 01—December 2014...
Protective field 2 × SC300 Figure 31 - Ergonomic workplace design due to the use of two SC300 (view from above) Notes In this application pay special attention to the correct mounting of the reflective tapes as shown in the diagram. The reflective tapes must always be perpendicular to the protective field area.
Protect the material transport using other measures. ATTENTION The SC300 does not monitor the material transportation with this mounting method. Protect the unmonitored areas on both sides of the material transport using mechanical guards.
Commissioning requires a thorough check by qualified safety ATTENTION personnel. Before you operate a system protected by the SC300 safety sensor system for the first time, make sure that the system is first checked and released by qualified safety personnel. Please read the notes in the “On safety”...
Check that personnel or body parts can only intrude into the hazardous area through the protective field of the SC300 (e.g. if a mechanical guard has been removed).

Check the effectiveness of the protective device as described in “Test notes” on page 38. How to deactivate the internal restart interlock: Permanently connect the Reset/restart input to 24V (“Connecting the SC300” on page 28). Switch on the SC300.
Switch on the SC300. Perform a teach-in procedure using the key-operated pushbutton for teach-in. The SC300 locks the internal teach-in key and saves this configuration in the device. Teach-in can now only be performed using the key-operated pushbutton for teach-in.
Care and maintenance The SC300 safety camera system is maintenance-free in operation. The front screen on the SC300 as well as the reflective tape should be cleaned regularly and also cleaned immediately in case of soiling. Do not use aggressive cleaning agents.
To place the device back in operation: Rectify the cause of the fault following the information given in this chapter. Switch the power supply for the SC300 off and on again (e.g. by unplugging the system plug and reinserting it).
