There are many manufacturing processes that require human operators to perform tasks, which can create hazardous levels of particulate, fumes, gases, vapors, and mists. A few of these processes include: welding, sanding, grinding, brazing, laser cutting, tempering, and quenching. The Occupational Safety and Health Administration (OSHA) has regulatory requirements to reduce worker’s exposure to these hazards, which can cause respiratory and other health issues. Downdraft tables are workstations designed to better protect the operators who perform these tasks, in a bench top setting, by removing the hazardous material that laden the air from the worker’s breathing zone.

Several applications require manual reset switches, which are switches that need to be physically reset by an individual for a process to continue or restart. A manual reset is often needed when an area has to be inspected prior to equipment restart. This can help to ensure the safety/inspection of both equipment and other individuals in the area.
Some switches have a mechanical manual reset (such as the Dwyer Series 1900, 1831, and 1800). However, there may be a need to have a manual reset for applications beyond what these switches are designed for. If a pump is allowed to run with a clogged filter, for example, this may severely damage the pump. Continue reading “How to Program a Switch for Manual Reset”
