Three safety functions were to be reproduced on the inline measurement system– emergency stop, a safety gate required for setup and maintenance work, and a safety flap to prevent intervention in the upstream machine. In safety technology terms the safety solution also had to harmonise with the upstream and downstream production process. The safety solution …
PNOZmulti 2 carries out functional safety and burner control tasks as a complete solution in a single system; these are tasks that were previously performed by separate burner controllers. That’s quite a challenge, as monitoring involves a complex control sequence: At the heart of every wafer production line is the oven, which may be up …
The risk analysis from Pilz showed that appropriate protective measures needed to be taken on the assembly cell for the two intervention areas as well as the five maintenance flaps. As the required safety solution was to be flexible, modular and expandable for use on similar plants, the decision went in favour of the configurable …
From the storeroom, several tonnes of paper reels travel across the production plant’s operating area because, due to lack of space, the plant is built “back to front”. That’s why each reel must be inserted manually by an operator, with a considerable loss of efficiency. Also, for reasons of infrastructure, the plant had been reset …
The safe solution applied at EuroChem comprises a radar system and PSSuniversal PLC controller from the automation system PSS 4000. Six radar sensors are attached to each of the conveyor’s six discharge points. They reliably detect all movements in the surrounding area. Each discharge point has its own control unit, which interprets the sensors’ signals …
The CGM rotary indexing table is a servo-driven, modular and flexible fully automatic machine. A driven axis is responsible for the movement of the rotary table as well as the vertical and horizontal stroke. The motion control system PMCprimo DriveP specifies the movements and is responsible for the whole motion and safety management of the …
In addition to using PSS 4000, Arcelor Mittal also commissioned Pilz to completely overhaul the plant. One challenge in this modernisation process was the frequent shutting down of the start-up burners that ignite the main burners, which repeatedly led to extended outages. The existing burner control module and flame monitoring via UV cells were not …
The challenge: the rear access areas also have to be protected. On their own, however, the pair of safety light curtains provided did not offer rear access protection. The solution: a safety laser scanner PSENscan is added to the safety concept. Installed centrally underneath the test system racks, it permanently scans a defined safety zone …
To completely exclude a potential hazard, it is essential to comply with the prescribed minimum values for water flow, water pressure and air pressure when the nozzles are used. The automation system PSS 4000 now takes the place of the previous system in monitoring the nozzles and the machine – with an optimised function range. …
The automation system’s PSSuniversal PLC controller, in conjunction with the decentralised I/O system PSSuniversal, takes full control of the flight carousel on the Götterflug – from closing and locking the bars on the seats through to rotating the tower and monitoring the end positions of the extension arms. Coded safety switches PSENcode also manage the …
