Compactor control solution

When new Harmonised EN Standard, EN 16500:2014, a new construction guide to the safety of vertical compactors and balers, was introduced it brought some challenges, with the electrical and mechanical safety of these press machines being outlined. Wieland worked closely to assist Pearce Compaction in understanding and reacting to the standard in-line with the machinery Directive for the company’s vertical balers.

Wieland also assessed the company’s current machines in order to offer the best safety & interface solution package to ensure that their machines would comply, without heavily impacting financially on overall costs.

To be able to achieve this, not only were the safety systems assessed but also the total control, both electrically and mechanically, looking at where improvements and/or cost savings could be made, whilst assuring that everything adhered  to the new standard.

The final design outcome resulted in the replacement of part of the original control system and, instead, using the SamosPRO Compact Programmable Controller for all the safety control of their Two Hand Control, Emergency Stop circuit and mechanical safety. By doing this it therefore not only reduced the number of components within the system but, by also moving the relay control and safety to a software based programmable system, Pearce has gained flexibility and customisation to the type of systems that they could then offer their customers, including new features such as bale full counters, reordering of strap indicators, and number of hours used.

Wieland’s solution for Pearce has enabled full compliance with the new standard and an increase the machinery performance level of the system. It has also enabled a reduction in costs without any performance or safety compromise, along with additional functionality and reliability, increasing sales for Pearce with their fully compliant systems.
