OPTO-ELECTRONIC SAFETY The design also yields advantages if a defect The advanced technology of the OSE yields a should arise: The safety edge can be replaced immediately Simple assembly during the technician's first visit. Repairs are there- High safety fore quick and inexpensive. High environmental stability Because defects in the safety edge are usually High flexibility. limited to the rubber profile, the OSE can be replaced quickly and easily keeping repair costs low For the customer, this not only means lower costs, and down time to a minimum. but also very high reliability and ready for...

OPTO-ELECTRONIC SAFETY High resistance to weathering and aging High mechanical stability Large temperature range performance Existing profiles can be used if suitable (dependent upon geometry and material). The rubber profile can be produced to the customer's specific requirements. This permits a large variety of profile shapes (folding gates, The intelligence of the safety edge is located in the high-speed gates, etc.) while keeping profile Simple interface to the control unit can easily be integrated into the gate control Automatic adjustment of the transmitter power Due to the dynamic principle,...

This further enhances the allows users to install the safety edge themselves. availability of the safety edge. Only a few components are required and can be combined into a perfectly functioning safety edge without requiring any special tools or technical know-how. moving edge (l.g. bottom section) Control unit OSE-C Alu-C Profile The receiver responds to failure of the dynamic IR Receiver OSE-R Bumper OSE-B light beam by generating an error message which...

OPTO-ELECTRONIC SAFETY Since the transmitter is effectively self-controlled, Since the signal interface between transmitter and the actuation- and the over travel are effectively receiver is well documented, the control unit can independent of the profile length. These parame- also be integrated into the gate control system. In ters are consequently determined by the speed of this case, the sensors can be connected directly to the gate and the shape of the profile. The product the terminals provided for this purpose. A current range already includes a large variety of profile list of control...

OPTO-ELECTRONIC SAFETY The safety edge can be installed directly on site, Installation of the opto-electronic safety edge (any because special tools and adhesives are not re- installed position) is a simple matter. Proceed as quired. The mechanical assembly should be exe- cuted by a skilled employee, the electrical connections by an electrical specialist.
