Operating Instructions Safety Switches CES-AR-C.
Operating Instructions Safety Switches CES-AR-C.2-AH 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 Switches CES-AR-C.2-AH 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 Switches CES-AR-C.2-AH Exclusion of liability and warranty In case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed, or if any servicing is not performed as required, liability will be excluded and the warranty void. General safety instructions Safety switches fulfill personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Operating Instructions Safety Switches CES-AR-C.
Operating Instructions Safety Switches CES-AR-C.2-AH If the safety door with the actuator should settle over time, the actuator can drift out of the read head operating distance. The device recognizes this and indicates that the actuator is in the boundary area (function available for V 1.1.2 and higher). This allows the safety door to be readjusted in time.
Operating Instructions Safety Switches CES-AR-C.2-AH Mounting Caution! Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffective. ÌÌOn this topic pay attention in particular to the measures for reducing the possibility of bypassing according to EN 1088:1995.A2:2008, sec. 5.7. Caution! Risk of damage to equipment as a result of incorrect installation. Safety switches must not be used as a mechanical end stop.
Operating Instructions Safety Switches CES-AR-C.2-AH 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 (OA and OB) must always be evaluated.
Operating Instructions Safety Switches CES-AR-C.2-AH 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 Switches CES-AR-C.2-AH 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 Switches CES-AR-C.2-AH 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 5 x 0,34 mm2 5 x 0,34 mm2 STATE DIA 5 x 0,34 mm2 oder 5 x 0,14 mm2 STATE DIA CES-AR # n CES-AR # n-1 n Iout (mA) Max.
Operating Instructions Safety Switches CES-AR-C.2-AH 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-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 Switches CES-AR-C.2-AH 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 Switches CES-AR-C.2-AH Warning! In case of an error, loss of the safety function through 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 Switches CES-AR-C.2-AH 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.
