AR-Auswertung

Your advantages

Quick overview of the status of each switch in the chain
Safety relay already integrated
Reduced wiring effort due to AR technology
Easy to service due to plug-in connection terminals

Design and functionality

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. Connected 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 as well as any diagnostic messages present.

AR evaluation unit CES-AR-AES-12

Central evaluation of an AR switch chain
Status of each individual switch can be seen
For switch chains of up to 12 devices
Four individual safe relay contacts
Category 4/PLe according to EN ISO 13849-1

Important:Only safety switches CES-AR-C01..., CES-AR-CR2..., CES-AR-CL2 with a serial number from V 1.1.2 (see rating plate on the device) can be connected to the AR evaluation unit. The communication between this evaluation unit and the safety switches CET1-AR-... and CET2-AR-... from V 1.1.2 is expected to be available by the end of 2011.

Function

The AR evaluation unit is used to evaluate the individual safety switches in a CES-AR-... switch chain and the safe interruption of a safety circuit.

The unit has two inputs for connection of a CES-AR... switch chain. The safety contacts are switched as a function of the input signals. Downstream parts of the safety circuit can be monitored using a feedback loop.

The switching states of the connected safety switches can be signaled by means of monitoring outputs.

If the actuator on one of the safety switches in the switch chain is moved out of the operating distance, the AR evaluation unit opens its contacts and the corresponding monitoring output is reset.

The system is designed so that failures will not result in the loss of the safety function. The occurrence of failures is detected by cyclic self-monitoring at the latest at the next demand to close the safety contacts.

The system can be started either manually using a start button or automatically.

Category according to EN ISO 13849-1

Due to two redundant safety paths (relay contacts) with 2 internal, monitored normally open contacts per safety path, suitable for:

Category 4 / PL e according to EN ISO 13849-1

Each safety path is independently safe.
