Know How: CONTROL SYSTEM OF BOTTLE FILLER FACILITY
What is specific for this control system is that it has been carried out in Ex realization. The system consists of Omron Touch panel 12’’ certified for Ex and control part, in which Omron PLC CJ series with two OMRON frequency invertors are placed. The control part is physically distanced from filler itself, and signals arrive and leave over Ex barrier. Also, the system is specific by the fact that servo drive is not used. Instead a classical (asynchronous motor and frequency inverter) used, contributed to lower the costs of entire system.
The control system has two basic operating modes: maintenance and automatic. In maintenance mode, basic system parameters adjustment is performed and faultiness is tested, while in automatic, there are two main modes: filling and washing. The system is completely freely configurable, both in mechanical and software sense – it has filling nozzles flexibility in each direction and sizes, while it can memorize up to 5000 recipes, or types of filling.
