System Manual Safety System CES-A-S5H01 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-S5H01 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. The face is marked with the EUCHNER logo. The center of the circle corresponds to the middle of the read head. 1. Remove clamp from read head by undoing the screws (1). .
System Manual Safety System CES-A-S5H01 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-S5H01 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-S5H01 Electrical Connection Warning! Loss of the safety function due to incorrect connection.

System Manual Safety System CES-A-S5H01 Warning! Electrical connection may only be performed by authorized personnel trained in EMC and with the device and wiring isolated. The device is fully encapsulated, it is therefore not possible to remove the lid from the housing. Important! If the device does not appear to function when operating voltage is applied (e.g. green STATE LED does not illuminate or flash), the safety switch must be returned unopened to the manufacturer.

System Manual Safety System CES-A-S5H01 Teach-in function for actuator The safety actuator must be allocated 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-S5H01 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.
