Operating Instructions Safety Switch CES-I-AR-M-C04 About this document This document is valid for all safety switches CES-I-AR-M-C04. 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.
Operating Instructions Safety Switch CES-I-AR-M-C04 Important! 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. ÌÌWhen up to 11 devices are connected in series, these limit values can be assumed for the entire switch chain as a subsystem. As a subsystem, this switch chain achieves PL e.
Operating Instructions Safety Switch CES-I-AR-M-C04 General safety instructions Safety switches fulfill personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Operating Instructions Safety Switch CES-I-AR-M-C04 Function The device complies with the following safety requirements: ÌÌSafety category 4, PLe according to EN ISO 13849-1 ÌÌRedundant design of the circuit in the unit with self-monitoring ÌÌThis means that the safety system still functions even if an internal component fails ÌÌThe switch state of the semiconductor outputs is continuously monitored internally ÌÌShort circuit detection at the safety outputs by pulsed signals The following switch-on condi
Operating Instructions Safety Switch CES-I-AR-M-C04 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 on the next demand to switch the safety outputs (e.g. on starting). If the safety door with the actuator should settle over time, the actuator can drift out of the switch operating distance. The device recognizes this situation and indicates that the actuator is in the limit range.
Operating Instructions Safety Switch CES-I-AR-M-C04 Mounting Caution! Risk of damage to equipment as a result of incorrect installation. Safety switches must not be used as a mechanical end stop. ÌÌFit an additional end stop for the movable part of the safety guard. Important! ÌÌFrom the assured switch-off distance Sar, the safety outputs are safely shut down. ÌÌWhen mounting several safety switches and actuators, observe the stipulated minimum distance to avoid mutual interference.
Operating Instructions Safety Switch CES-I-AR-M-C04 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 case of an error, loss of the safety function through incorrect connection. ÌÌTo ensure safety, both safety outputs (FO1A and FO1B) must always be evaluated.
Operating Instructions Safety Switch CES-I-AR-M-C04 Caution! ÌÌIn order to avoid EMC interference, the physical environmental and operating conditions at the installation site of the device must comply with the requirements according to the standard EN 60204-1:2006, section 4.4.2 (EMC). Important! If the device does not appear to function when operating voltage is applied (e.g. green STATE LED does not flash), the safety switch must be returned unopened to the manufacturer.
Operating Instructions Safety Switch CES-I-AR-M-C04 Maximum cable lengths Switch chains are permitted up to a maximum overall cable length of 200 m taking into account the voltage drop as a result of the cable resistance (see table below with example data and case example). lmax =200 m l2 l1 ln un = 24 V -20% umin = 24 V -10% iout SPS PLC 5 x 0,34 mm2 oder 5 x 0,14 mm2 5 x 0,34 mm2 CES-I-AR # n 5 x 0,34 mm2 CES-I-AR # n-1 n Iout (mA) Max.
Operating Instructions Safety Switch CES-I-AR-M-C04 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) (conductor cross-section 0.34 mm²). Cables with a length of 20 m each are connected between the individual CES-I-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-I-AR-M-C04 Connection of a single CES-I-AR If a single CES-I-AR is used, connect the switch as shown in Figure 3. The OD 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-I-AR complies with PL e in accordance with EN 13849-1.
Operating Instructions Safety Switch CES-I-AR-M-C04 Warning! In case of an error, loss of the safety function through incorrect connection. ÌÌTo ensure safety, both safety outputs (FO1A and FO1B) 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-I-AR-M-C04 Connection of several CES-I-AR 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.
