Page 5: General
General General The SLS 78/R Single Beam Safety Device is an a type 4 active opto-electronic protective device (AOPD) in accordance with EN IEC 61496-1, EN IEC 61496-2 and ISO 13849-1, and is equipped with two safety relays (positive-driven contacts). A protective field of infrared beams is generated between the transmitter and receiver of the safety light beam device. -

(e.g. EN ISO 14121, EN ISO 12100-1, ISO 13849-1, IEC 61508, EN 62061). The result of the risk assessment determines the required safety level of the safety sensor (see Table 2.1-1.). For mounting, operating and testing, document "SLS 78/R Single Beam Safety Light Barrier" as well as all applicable national and international standards, regulations, rules and directives must be observed. -

Page 9: Operating Mode
It applies for the SLS 78/R that people are only detected during the access; their presence in the danger zone, however, is not detected! If a person interrupts the light beam or if there is an AOPD fault, the safety sequential circuit must therefore go into safe interlock. -

Page 19: Examples For The Safe Integration Of The Sls 78/R In The Machine Control
Examples for the safe integration of the SLS 78/R in the machine control Various SLS 78/R connection options are possible. If the safety-related control system of the machine has the interlocking and monitoring functions required for the integration, such as “Start/restart interlock” and “Contactor monitoring", then the direct connection of the single beam safety device to the control system is possible. -
Page 20: Initial Operation
Bild 7.0-1: Warning: Before putting the SLS 78/R into operation for the first time on a power-driven production machine, an experienced and commissioned person with suitable training must check the entire setup and the integration of the opto-electronic protective device into the machine control system. -
Page 21: Alignment
For this, see also the diagram with minimum distances in chapter 5.7. 10. After the alignment has been completed the SLS 78/R must be fixed again. 11. After the alignment and initial operation work has been completed the proper functioning is checked using an object of at least 30 mm diameter at every point of the beam path between the transmitter and the receiver. - Page 22 LED on receiver: Red Alignment insufficient LED on receiver: Red and yellow, flashing Alignment bad LED on receiver: Green and yellow, flashing Alignment good LED on receiver: Green a = Transmitter b = Receiver Optical alignment check Bild 7.1-1: SLS 78/R Leuze electronic...
