    INTRODUCTION 7000 Series Safety Light Curtains The 7000 Series offers a wide range of models for finger, hand, leg and body protection. The 7000 system from Smartscan is compact in size and provides many sophisticated control features as standard, including: 2 and 3 beam floating blanking for press and press brake applications, external test and auto or latched reset control options.
  • Page 6 Guillotines Production lines Robots 7000 Series light curtains comply with British and International Safety Standards for Light Curtains BS EN 61496-1 & BS IEC 61496-2 Type 4. They are normally used in situations which demand a high level of safety integrity, where the risk assessment for the safety related parts of a control system, as indicated in BS EN 954-1, determines a requirement up to and including Category 4 control equipment.

  • Page 54 APPENDIX 2 Alignment though two mirrors 9. Follow instruction 1-4 10. A second person must adjust the position of the first mirror to the left and to the right until the entire length of the second mirror is reflected in the first mirror. If difficulties are experienced in seeing the reflection on the second mirror in the first mirror then use a piece of white paper cut to size and position in front of the second mirror.
  • Page 55 APPENDIX 2 16. Now turn on the power to the light curtain and check that the green LED beam indicator, mounted on the receiver unit is ‘on’. If not, it may be necessary to finely adjust each mirror in turn to ensure the infra-red energy from the transmitter unit is being reflected through the mirror(s) to the corresponding receiver unit.
