Presses and stamping lines
On a press, the point of operation is centimetres from the hands during manual loading and unloading. A fixed guard on the front slows every cycle, and a simple start button is operated with one hand while the other is free to enter the danger zone. During a die change, staff work inside the machine: if someone energises it from the panel while a person is between the platens, the accident is severe.
PSENopt II Type 4 safety light curtains, PLe per ISO 13849-1, on the loading side: 14 mm resolution for finger protection or 30 mm for hand protection, with no dead zones (except at the 150 mm height). The operator loads the part without opening a guard, and the press does not close while a hand is in the field. Blanking for parts or tools that pass through the field in a fixed position, and cascading to protect several sides of the machine. They withstand shocks up to 50 g and operate from -25 to +60 °C. The PNOZsigma relay, with time-delayed contacts from 0.04 to 300 s, handles stop category 1 and releases the guards only once the press has finished braking (SIL 3, PLe, Cat. 4).
Two-hand control: forces both hands to stay outside the point of operation on manually cycled presses, PLe per ISO 13849-1 and ISO 13851. Trapped key interlocking for die change: the access sequence is enforced mechanically, independent of electronics, and the key that opens the guard cannot be in the panel at the same time. 4000 N RFID Guard Locking for side and rear doors.
