NS series safety switches with solenoid and RFID technology

NS series safety switches with solenoid and RFID technology Maximum safety with a single device Description These switches are used mainly on machi‑ nes where the hazardous conditions persist even after the machine has been switched off. Mechanical parts such as pulleys, saw blades, etc., could continue to move after the machine is switched off or could still be hot or under pressure. Thus, the switches can also be used if individual guards are only to be opened under certain conditions. Versions with mode 1 (safety outputs active when guard closed and locked) are interlocks with guard...

Six LEDs for immediate diagnosis As the LEDs have been designed for quick immediate diagnosis, the status of each input and output is highlighted by one specific LED. This makes it possible to quickly identify the interruption points in the safety chain, which device is released, which door is opened and any errors inside the device. All of this at a glance, without needing to decode complex flashing sequences. Holding force of the unlocked actuator The inside of each switch features a device which holds the actuator in its closed position. Ideal for all those appli‑ cations where several...

Activation mode of the OS1 and OS2 safety outputs Mode 1 S Safety outputs OS1 and OS2 are active when the actuator is inserted and locked. Safety outputs OS1 and OS2 are active when the actuator is inserted. Safety output OS1 is active when the actuator is inserted and locked and IS1 is active. Safety output OS2 is active when the actuator is inserted and IS2 is active. Interlocking Locking function function In case of machines with or without inertia of the dangerous elements. Safety category of the safety outputs: PL e, SIL 3. In case of machines without inertia of the dangerous...

Complete safety system The use of complete and tested solutions guarantees the electrical compatibility between the NS series switches and the safety modules from Pizzato Elettrica, as well as high reliability. The switches have been tested with the modules listed in the adjacent table. The diagram on the side represents the 7 logic functions which interact inside the device. 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 device inputs, whereas function f2 monitors the presence of...

Actuation sequence in mode 1 PWR ♦ ACT O IN 9 LOCkO OUT O The switch is supplied with power (PWR LED on, green), the IS1 and IS2 inputs are enabled (IN LED on, green), the OS1 and OS2 safety outputs are disabled (OUT LED off). The actuator is outside of the actuation zone (LED ACT off). When the actuator is brought inside the safe actuation area (dark grey area), the switch turns on the ACT LED (green). In this position, the O3 signalling output (door-closed) is activated. The actuator is not locked (LOCK LED off). The IE1, IE2 inputs can be used to lock the actuator (LOCK LED on,...
