Safety Mats & Area Guarding UMA Series UMA Safety Mat System Heavy-duty two-wire or four-wire presence sensing safety mats with quick disconnect cables, perimeter trim and Cat. 3 controllers System When UMA series mats are combined with an SCC-1224A, MC3, or other Omron programmable safety controller (with complete diagnostics), the result is a system that meets the standard EN ISO 13856-1 and is entitled to display the CE mark. See below for an overview of the various components. UMA Series Mat IP65 rated Single-piece molded polyurethane (PUR) construction Black or yellow color LISTED Easy cable connection Controllers Safety category 3 devices SCC-1224A DIN-rail mount (MC3) Description Trim One-part or Two-part perimeter and joining trim simpli es The UMA Mat System o ers quick-connect M8 connectors installation on the mat that easily conceal under the trim o ering easier Two options for trim kit corners: Mitered and molded installation and quick replacement. The system can be used with with the MC3 and SCC-1224A controller UMA mats can also be directly connected to NX-S or G9SP programmable safety controllers eliminating the need to intermediate controllers. Applications Safety Mats are ideally suited to harsh environments where devices such as laser scanners and light curtains can false trip Presence sensing safety mats are used to monitor an entire due to contaminants in the environment. Safety mats when used hazardous area. They o er exibility, quick access and may as a start-up prevention device o er additional worker protection frequently be the most economic choice. Other options for o ering continual detection in hazardous areas. perimeter guarding include interlocked barrier guards and safety light curtains. However, personnel can become trapped inside a barrier guard and safety light curtains only monitor the perimeter, How the System Works not the hazardous area inside. Additionally, mats can also simplify The operation of a UMA Mat system is easy to understand. The routine tasks such as machine setup, maintenance and repair. mat is a simple, normally open switch. When a speci ed minimum Applications can be found throughout industry and typically include weight is applied to the mat the switch closes. This sends a the following areas: signal to the controller which, in turn, sends a stop signal to the Welding Robots guarded machine.
