Design and principle of operation

Using the AR evaluation unit, AR switch chains with up to 12 devices can be evaluated. All relevant status information on the switches connected is routed to the evaluation unit using only two inputs. The four safety outputs are switched depending on these input signals. Downstream parts of the safety circuit, e.g. contactors, can be monitored via a feedback loop. The system can be started either manually using a start button or automatically. With a total of 14 monitoring outputs, the CES-AR-AES supplies downstream control systems with information on the switching state of each safety switch, as well as any diagnostic messages present.
