System 2

Control of the flow of boxes on a packing line

There was an existing control panel, (see first photo) the central part of which was a Siemens S5 plc. The equipment it controlled was being re-installed in a slightly different configuration, and with additional conveyors and sensors. PJC Systems changed the plc to a Mitsubishi FX1S, added the necessary additional starters, replaced missing trunking lids, replaced trunkings where necessary (see second photo), rewrote the plc software, and commissioned the system on site.

To enable the system to perform as required, great attention had to be given to the timing of the system.

PJC Systems spent time to evaluate the system, which had to be set up to allow the faster lines to have priority over the slower lines.
