ST series safety sensors with RFID technology Introduction In combination with the corresponding safety modules, the sensors of the ST series are suitable for the monitoring of protective devices on machines without inertia and allow the system in which they are used to reach a safety category up to SIL 3 acc. to EN 62061 as well as up to PL e and Category 4 acc. to EN ISO 13849‑1. These sensors use RFID (Radio Frequency IDentification) technology and provide high protection against possible manipulation thanks to the uniqueness of the codes transmitted by the actuator. Because they have no...

Laser engraving Pizzato Elettrica supplies a pro‑ grammable version of the ST series sensors. With a simple and brief ope‑ ration, the sensor can be program‑ . med to recognise the code of a new 0.. 011 actuator. 010 0 By activating a special input, the sensor is switched to a safe state, during which it waits for a new code to be accepted. As the actuator approaches, the ST sensor performs a number of checks on the code being received, whereby the code must adhere to certain parameters of RFID technology. If the checks are successful, the sensor uses LEDs to signal the suc‑ cessful...

Complete safety system The use of complete and tested solutions guarantees the electrical compatibility between the sensors of the ST series and the safety modules from Pizzato Elettrica, as well as high reliability. The sensors have been tested with the modules listed in the adjacent table. The adjacent diagram illustrates five logical, linked sub-functions of the sensor. Function f0 is a basic function and includes the monitoring of the power supply as well as internal, cyclical tests. Function fl monitors the status of the inputs, whereas function f2 monitors the position of the actuator...

Limit activation zone and safe activation zone (ST D^4«m) When aligning the sensor with the actuator, the status LEDs use various colours to indicate whether the actuator is in the limit activation zone or in the safe activation zone. The following figures use the ST DD420MK-D1T sensor as an example. Oldl rffjt /// ACT IN OUT PWR Operating voltage is applied to the sensor, (LED PWR on, green), the inputs are enabled (LED IN on, green), the outputs are deactivated (LED OUT off). The actuator is outside of the actuation zone (LED ACT off). If the actuator is moved inside the safe activation...
