Description

LPR®-SAFE is a system for safe distance measurement compliant with the functional safety standard EN ISO 13849 PLd. It is suitable for semi-automatic and automatic crane systems or rail-bound vehicles, for example. LPR®-SAFE consists of LPR®-1DHP-291 (60 GHz) or LPR®-1D24 (24 GHz)series radar distance measurement sensors which, together with a certified function block (EN ISO 13849 PLd) on a fail-safe Siemens PLC, enable precise, functionally safe distance measurement. Two redundant measuring sections with two sensors each, all of the same type, are set up for this purpose. Both measuring sections operate in redundant secondary radar mode ensuring that the measurement only takes place to the appropriately configured partner unit. Each of the two redundant measuring sections provides distance values, which are forwarded to a fail-safe PLC, where the measured distances are compared in the certified function block (EN ISO 13849 PLd). The measured values can be read and compared on one or both sides of the measuring section with its own PLC on each side. If the deviation of the measured distances of both sections is within the permissible tolerances, the measured values are marked as safe. If not, the measurement is marked as unsafe and corresponding actions can be triggered on the (crane) system side. Depending on the sensor type used, different ranges and accuracies result. The applications: • Position Detection • Distance Measurement • Collision Avoidance • Customized Solutions
