The sectional drive of the paper machine
The supply has essentially managed the 8 AC 690V motors of the paper machine and 6 other 690V AC motors for the hood pumps and fans. The Machine automation has provided the classic functions of our sectional drive with the management through our exclusive “DCS in DRIVE” control system, with which we can say today, of being at the peak of any technical comparison in the sector. The DCS supervision system adopted was traced by our installed “SAEL paper machine supervisor” with on board trends, synoptics, alarms history, recipe management and remote assistance.
Using this system, the machine maintenance team can check before intervening where the problems are focused; in case of night technical support, the electronic SAEL technician directly from home, can connect to the server and guide the internal factory staff at the restart of the machine.
The automation of TURBOGAS, Nuovo Pignone and General Electric
The supply concerned the migration of the existing control system in which, even in this case, the availability of spare parts and the possibility of optimizing its operation had become almost impossible to handle. The various disturbances and the almost complete impossibility of understanding its motivations have pushed the paper mill towards our idea of replacing the MOORE control system currently in use and all its logic, with a new commercial PLC with OPEN SOURCE software. As requested the control system was developed on PLC Siemens S7-1500, I / O ET200MP Siemens, the CPU and I / O cards were installed in the existing framework, in the position of the Existing PLC.
The omnipresent Mr. Mario Lovato, CEO of the paper mill, together with Mr. Andrea Vivaldi, responsible for electrical maintenance, with this construction and start-up have obtained, in addition to the training of their technicians, a form of insurance on the plant. Absolutely and unequivocally, they have the peace of mind that, in case of anomalies or work problems, their technicians can intervene autonomously and promptly reduce the stop times to zero. Moreover, Internet World Sael Assistance has allowed us to annihilate our distances from the Zevio plant (Verona).
