The Advanced Technology of the OSE Yields a Number of Advantages:
Simple assembly
High safety
High environmental stability
High flexibility
For the customer, this not only means lower costs, but also very high reliability and ready for availability of the safety edge.
Assembly The OSE can be installed very simply and easily. Single components can be exchanged very easily. The aluminum rail and the rubber profile are supplied as endless sections which are cut to the required length. Transmitter and receiver are then inserted into the rubber profile and wired to the electronic control unit. It is not necessary to bond or preassemble the components. The simplicity with which the rails can be assembled yields the following advantages:
Neither technical know-how nor special tools are required to install the safety edge
The quality of the safety edge does not depend on its assembly
The system can be installed without difficulty directly on site
Short delivery times
Simple logistics and cost-efficient stock keeping
Lower production costs
The Design also Yields Advantages if a Defect Should Arise:
The safety edge can be replaced immediately during the technician's first visit. Repairs are therefore quick and inexpensive. Because defects in the safety edge are usually limited to the rubber profile, the OSE can be replaced quickly and easily keeping repair costs low and down time to a minimum.
Machine downtimes and gate stoppages can be minimized.
Safety The high safety and reliability of the OSE is due to the dynamic transmitter-receiver concept. Approved by the employers' liability insurance associations (BG) up to safety category 4 as defined by DIN EN 954-1.
Broken wires and short-circuits are detected in the coiled cable (and in the transmitter / receiver leads)
All deviations from the normal operating condition are detected
The system is self monitoring. Defects are detected in advance of accidents
Environmental Stability
Total resistance to moisture
High resistance to weathering and aging
High mechanical stability
Large temperature range
High resistance to weathering and aging
High mechanical stability
Large temperature range performance
The Intelligence of the Safety Edge is Located in the Transmitter and Receiver:
Simple interface to the control unit can easily be integrated into the gate control
Automatic adjustment of the transmitter power in accordance with the length of the safety edge
Compensation of any aging phenomena in the rubber profiles
Moisture and dirt in the profile can be compensated within limits
Complex integrated receiver circuit ensures extensive resistance to extraneous light
No sensitive lines to the control system and therefore no problems as regards EMC
Connecting lines to the sensors can be up to 200 meters long.
The Completely Sealed Sensors are Located at the Ends of the Safety Edge.
The part of the safety edge that is most susceptible to vandalism is comprised of a rubber profile for which standard materials are used (sulphur-crosslinked EPDM)
Operation is not affected by minor damage to the rubber
Flexibility
The ease with which the safety edge can be assembled gives the user or engineer great flexibility allowing for extensive variability in planning.
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, high-speed gates, etc.) while keeping profile and tool costs low.
The system's electronic components (transmitter and receiver) are completely enclosed in a special sealing compound assuring the protection of an IP 68 enclosure. This gives the sensor element of the safety edge the following properties:
