Operating Instructions Safety System CES-A-ABA-01/CES-A-ABA-01B 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 System CES-A-ABA-01/CES-A-ABA-01B General Safety Instructions Safety switches fulfill personal protection functions. Incorrect installation or tampering can lead to severe injuries to personnel. The number of teach-in and switching operations is saved in the internal memory in the evaluation unit. If necessary, this memory can be read by the manufacturer.
Operating Instructions Safety System CES-A-ABA-01/CES-A-ABA-01B Function The safety system CES-A-ABA... complies with the following safety requirements: Ì Category 3, PLe according to EN ISO 13849-1 Ì Proximity device with self-monitoring type PDF-M according to EN 60947-5-3. Ì 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.

Operating Instructions Safety System CES-A-ABA-01/CES-A-ABA-01B Installation Caution! Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffective. Ì 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. Ì The evaluation unit must be mounted in a control cabinet with a minimum degree of protection of IP 54.
Operating Instructions Safety System CES-A-ABA-01/CES-A-ABA-01B Note the following points: Ì Actuator and read head must be easily accessible for inspection and replacement. Ì The switching operation must only be triggered by the specific actuator designated for this purpose. Ì Actuator and read head must be fitted so that Ì the front faces are at the minimum switch-on distance 0.8 x Sao or closer (see section Operating distances).
Operating Instructions Safety System CES-A-ABA-01/CES-A-ABA-01B Electrical Connection Warning! In case of an error, loss of the safety function through incorrect connection. Ì To ensure safety, both safety outputs (13/14 and 23/24) must always be evaluated. Ì The monitoring output OUT must not be used as a safety output. Ì Lay the connection cables with protection to prevent the risk of short circuits. Caution! Risk of damage to equipment or malfunctions as a result of incorrect connection.
Operating Instructions Safety System CES-A-ABA-01/CES-A-ABA-01B Safety in case of faults Ì The operating voltage UB is reverse polarity protected. Ì The connections for the read heads, ERR and OUT are not short circuit-proof. Ì A short circuit between 13/14 and 23/24 can be detected only by means of external pulsing. Ì A short circuit in the cable can be excluded by laying the cable with protection. Fusing of the power supply and the safety contacts.
