The manufacturing process consists of a large rotating table, where the cable is spooled out and guided to 17 different spinners which are protected by a total of 68 Eden sensors. Each spinner rotates around the cable and has 16 paper rolls which are all simultaneously rolled out overlapped onto the cable. The cable is then coiled up in a intermediate storage facility where it awaits to be spooled into an oil bath. After this the cable is inserted into a lead pipe which is then sealed and reinforced.
The manager responsible for the machine safety on the NorNed project at ABB HVC is Jan Olof Sandberg who has discussed and reviewed different safety solutions together with Jokab Safety AB.
Jan Olof knew from earlier experience that the Eden safety sensor was an ideal sensor for use on the older spinner lines at ABB HVC. This is why Eden and Tina products, which are monitored by the Pluto safety PLC, were the perfect choice for monitoring the old machines and at the same time use new technology in an easy way.
Jan Olof himself would take care of the design work and the programming of Pluto at the same time as managing the installation work. In order to achieve this, Jan Olof attended a one-day Pluto training seminar at Jokab Safety to obtain basic programming knowledge. He also received an introduction on how to best utilize the Pluto system. The knowledge obtained by Jan was sufficient for him to be able to program the entire safety system. To prevent problems and possible future errors the program was reviewed by Erik Cascalheira from Jokab Safety’s Pluto support team.
"To obtain control of my programming was an assurance because this was my first Pluto installation", says Jan Olof Sandberg. He also says that the project has been a success because of good support before, during and after the project and due to excellent training.
