Safety switch CET-AP

Benefits for you

  • Safety switch with guard locking and safe guard lock monitoring
  • Integrated CES-AP electronics
  • A special evaluation unit is not required
  • Safety category 4 and PL e according to EN ISO 13849-1 in any installation orientation, head downward/upward/horizontal
  • Two safe semiconductor outputs and monitoring output OUT
  • Safety outputs with pulsing
  • Input (optional) for the connection of feedback loop and start button

Design and functionality

The CET-AP forms a complete safety solution (PL e according to EN ISO 13849-1). Depending on the version a start button and feedback loop can be connected. As a result, the CET-AP includes everything that is necessary to secure a guard. It could not be easier!

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 1 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.

Connection to decentralized peripheral systems (e.g. ET200pro)

Switches of series CET-AP-...-SI-... (2x plug connectors M12) have a special pin assignment that makes possible direct connection to decentralized peripheral systems, e.g. Siemens ET200pro.

OUT output

The semiconductor output OUT is switched if the guard is closed (actuator in the actuating range). It is not allowed to be used for safety functions. The OUT outputs on the individual switches can, however, not be polled if connected in series using a Y-distributor.
Evaluation is possible only on parallel wiring to the control cabinet.

RST input

The switches in a chain in a fault state can be reset using the RST input. To do this, a voltage of 24 V is applied to the RST input for at least 3 seconds. It is not necessary to disconnect the power supply to reset a fault.
