We designed the system and generated a set of electrical schematics to facilitate the manufacture of all the enclosures and field wiring listed.
We configured the hardware and created manual HMI screens on the Touch panel in the system software to operate the system. All alarms and feedback signals were going to be mimicked on the HMI’s.
DBI Control designed the system so that the operator of the machine is not caused undue stress or strain. After the system was successfully tested at our customers’ site, it was taken to our clients factory in Yorkshire where the completed equipment was successfully tested with all the panels networked and powered up.
The HMI screens were demonstrated for functionality and there was a trial of the completed system ensuring it was fully functioning with the product.
We supplied a comprehensive documentation pack, and technician training was given by DBI Control during the commissioning of the system.
DBI Control successfully delivered, installed and electrically commissioned all equipment to Thirsk, North Yorkshire within 8 weeks of the order being placed, giving the customer complete satisfaction by providing a high quality machine in a specified time frame.
