Operating Instructions Safety Switch CES-AH-C03-AH-SM Correct use The Coded Electronic Safety switches series CES are safety devices for monitoring movable safety guards. In combination with a safety guard, this safety component prevents dangerous machine movements from being performed for as long as the safety guard is opened. A stop command is triggered if the safety guard is opened during the dangerous machine function.

Operating Instructions Safety Switch CES-AH-C03-AH-SM 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-AH-C03-AH-SM System description The safety switch CES-AH-C03-AH-SM complies with the following safety requirements: ÌÌCategory 3 according to DIN EN ISO 13849-1 ÌÌProximity device with self-monitoring type PDF-S according to EN 60947-5-3.
Operating Instructions Safety Switch CES-AH-C03-AH-SM Montage 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, observe the stipulated minimum distance to avoid mutual interference. min.
Operating Instructions Safety Switch CES-AH-C03-AH-SM Electrical connection General notes Caution! Risk of damage to equipment or malfunctions as a result of incorrect connection. ÌÌTo avoid faults, the cable must be laid with protection. ÌÌThe power for the operating voltage and for the inputs +LA and +LB must be provided from a common power supply.
Operating Instructions Safety Switch CES-AH-C03-AH-SM Automatic restart and start button Pay attention to the notes for the following applications: Automatic start, with a jumper (+24 V are continuously present at the START input) ¨¨ The device restarts automatically after faults. Manual start (start via a start button) ¨¨ Prior to each restart the start button must be pressed ÌÌA sticking start button (fault due to welding etc.) is not detected by the device and results in an automatic restart.
Operating Instructions Safety Switch CES-AH-C03-AH-SM Voltage drop on cable and switch If a load is applied to the outputs, voltage drops will occur on the supply cables and on the switch. The voltage drops are to be taken into account during the calculation of the power available in the load connected. Parameter Value Unit Maximum resistance of an output path 250 mW Resistance for further connection cable (e.g.
Operating Instructions Safety Switch CES-AH-C03-AH-SM Connection cables and plug connectors Caution! Risk of damage to equipment or malfunctions as a result of incorrect connection cables. ÌÌUse EUCHNER connectors. ÌÌIf other connection components are used, the following recommendations apply. EUCHNER provides no warranty for safe function in case of failure to comply with these requirements. ÌÌThe maximum cable length should not exceed 50 m. Recommended connection cable: e.g.

Operating Instructions Safety Switch CES-AH-C03-AH-SM Typical system times Ready delay: After switching on, the unit carries out a self-test for 3 s. The system is ready for operation only after this time. Risk time according to EN 60947-5-3: If an actuator moves outside the operating distance, the safety outputs LA and LB on the corresponding safety switch are deactivated after a maximum of 260 ms. Difference time: The safety outputs LA and LB switch with a slight time offset.
