System Manual Safety System CES-A-C5... 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.

System Manual Safety System CES-A-C5... System Description The safety switch CES-A-C... meets the following safety requirements: CES-A-C5E-01: Category 3, PLe according to EN ISO 13849-1 CES-A-C5H-01: Category 4, PLe according to EN ISO 13849-1 Proximity device with self-monitoring type PDF-M according to EN 60947-5-3. Redundant design of the circuit in the evaluation unit with self-monitoring. As a result, the safety system is still effective even if a component fails.

System Manual Safety System CES-A-C5... Changing the approach direction Caution! Risk of damage to equipment as a result of trapped cables. Make 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. 1. Unscrew the screws on the fastening bracket. . Pull the read head from the fastening bracket and tilt the read head by 90° (arrow 2).
System Manual Safety System CES-A-C5... Installation Caution! Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffective. On 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.
System Manual Safety System CES-A-C5... Actuator and safety switch must be fitted so that the front faces are at the minimum switch-on distance 0.8 x Sao or closer (see section Operating distances). To avoid entering the area of possible side lobes, a minimum distance is to be maintained in case of a side approach direction. See section Typical operating distance for the related actuator. when the safety guard is open up to the distance Sar (assured switch-off distance), a hazard is excluded.
System Manual Safety System CES-A-C5... Electrical Connection Warning! Loss of the safety function due to incorrect connection. Not suitable for safety relays that realize short-circuit monitoring with different potentials (0 V/24 V).

System Manual Safety System CES-A-C5... Caution! Power 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. If a common power supply is used, all the inductive and capacitive loads (e.g. relay contactors) connected to the power supply must be connected to appropriate interference suppressors.

System Manual Safety System CES-A-C5... Teach-in function for actuator The actuator must be assigned to the evaluation unit using a teach-in function before the system forms a functional unit. During a teach-in operation, the safety outputs and the door monitoring output OUT are LOW, i.e. the system is in the safe state. Important! Repeated teach-in of the same actuator on the same evaluation unit is not possible.
System Manual Safety System CES-A-C5... Functional check After installation and any fault, the safety function must be fully checked. Proceed as follows: Warning! Danger of fatal injury as a result of faults in installation and functional check. Before carrying out the functional check, make sure that there are no persons in the danger area. Observe the valid accident prevention regulations. 1. Switch on operating voltage. The safety switch carries out a self-test.
