Operating Instructions Safety Switch CES-AR-C01-EH-SA Correct use The Coded Electronic Safety switches series CES are safety devices for monitoring movable safety guards. In combination with a separating safety guard and the machine control, this safety component prevents dangerous machine movements from occurring while the safety guard is open. A stop command is triggered if the safety guard is opened during the dangerous machine function.
Operating Instructions Safety Switch CES-AR-C01-EH-SA Important! ÌÌIn the case of series connection of more than 11 devices, the PFHd can be calculated according to one of the stated methods in EN ISO 13849-1:2008, section 4.5.1. ÌÌIf the simplified method according to section 6.3 of EN ISO 13849:2008-12 is used for validation, the Performance Level (PL) might be reduced when more than 11 devices are connected in series.

Operating Instructions Safety Switch CES-AR-C01-EH-SA Changing the approach direction Caution! Risk of damage to equipment as a result of trapped cables. ÌÌMake sure that the cables are not trapped or torn off when the approach direction is changed. The active face of the read head can be adjusted in 5 directions. It is marked by the red face. The plug connector can be realigned in 45° steps to change the direction of the cable outlet (when using elbow connectors). 1.
Operating Instructions Safety Switch CES-AR-C01-EH-SA Mounting Important! ÌÌFrom the assured switch-off distance Sar, the safety outputs are safely shut down. ÌÌWhen mounting several safety switches, observe the stipulated minimum distance to avoid mutual interference. min. 80mm ÌÌIf the actuator is installed flush, the switching distance changes as a function of the installation depth and the safety guard material.
Operating Instructions Safety Switch CES-AR-C01-EH-SA Electrical connection The following connection options are available: ÌÌSeparate operation ÌÌSeries connection with Y-distributors from EUCHNER (only with M12 plug connector) ÌÌSeries connection, e.g. with wiring in the control cabinet. ÌÌOperation on an AR evaluation unit Warning! In the event of a fault: Loss of the safety function due to incorrect connection. ÌÌTo ensure safety, both safety outputs (OA and OB) must always be evaluated.
Operating Instructions Safety Switch CES-AR-C01-EH-SA Caution! ÌÌPower devices which are a powerful source of interference must be installed in a separate location away from the input and output circuits for signal processing. The cable routing for safety circuits should be as far away as possible from the cables of the power circuits.
Operating Instructions Safety Switch CES-AR-C01-EH-SA Requirements for connection cables Caution! Risk of damage to equipment or malfunctions as a result of incorrect connection cables. ÌÌUse connection components and connection cables from EUCHNER ÌÌOn the usage of other connection components, the requirements in the following table apply. EUCHNER provides no warranty for safe function in case of failure to comply with these requirements.
Operating Instructions Safety Switch CES-AR-C01-EH-SA Determining cable lengths using the example table Example: 6 switches are to be used in series. Cabling with a length of 40 m is routed from a safety relay in the control cabinet to the last switch (#6). Cables with a length of 20 m each are connected between the individual CES-AR safety switches. lmax = 140 m l2 = 5 x 20 m l1 = 40 m ln = 20 m un = min. 19,2 V Sicherheitsrelais iout = min.

Operating Instructions Safety Switch CES-AR-C01-EH-SA Connection of a single CES-AR-C If a single CES-AR-C is used, connect the switch as shown in Figure 3. The OUT output can also be connected here to a control system as a monitoring output. The switch can be reset via the RST input. To do this, a voltage of 24 V is applied to the RST input for at least 3 seconds. The RST input must be connected to 0 V if it is not used. Important! The subsystem CES-AR complies with PL e in accordance with EN 13849-1.
Operating Instructions Safety Switch CES-AR-C01-EH-SA Warning! In the event of a fault: Loss of the safety function due to incorrect connection. ÌÌTo ensure safety, both safety outputs (OA and OB) must always be evaluated. Single-channel use of the safety outputs leads to a loss of the category in accordance with EN ISO 13849-1.
Operating Instructions Safety Switch CES-AR-C01-EH-SA Connection of several CES-AR-C in a switch chain Important! ÌÌAn AR switch chain may contain a maximum of 20 safety switches. ÌÌIn the estimation of the PL for the overall system, a maximum value of 100 years can be assumed for the MTTFd according to the limit value in EN ISO 13849-1:2008, section 4.5.2. This corresponds to a minimum value for the PFHd of 2.47x10-8/h.
