Your advantages High protection against tampering Category 4 / PL e according to EN ISO 13849-1 Integrated short circuit monitoring Large operating distance Connection via plug connectors Diagnostics using LED The CES-AP makes transponder technology available to protect even very small guards and doors. The typical CES features such as large read distance and center offset are naturally also offered by the CES-AP. What is more, mounting on profile rails couldn't be easier. Design and functionality The safety switch CES-APÉ has two safety outputs. These outputs are connected directly to drives, downstream safety relays or safe control systems. The switch monitors itself for short circuits using pulsed signals. External clock signals are therefore not required. More information Indication for actuator in the limit range 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 situation and indicates that the actuator is in the limit range. This allows the safety door to be readjusted in time. Connection to safe control systems or safety relays Do not use a control system or safety relay with pulsing for monitoring short circuits or switch off the pulsing function in these devices. The switch generates its own clock signals on the output lines OA/OB. A downstream device must tolerate these test pulses, which may have a length of up to 0.4 ms. The inputs on the downstream device must be suitable for positive-switching devices (pnp outputs), as the two outputs on the safety switch deliver a level of +24 V in the switched-on state. OUT output (depending on version) The semiconductor output OUT is switched if the safety guard is closed (actuator in the operating distance). It is not allowed to be used for safety functions. DIA output (depending on version) The semiconductor output DIA is switched in the fault state. It is not allowed to be used for safety functions. Reset input
