Machine directive 2006/42/EC and ISO 13849-1 help protect operators from injury while working around pneumatically controlled production equipment. ASCO helps the design engineer satisfy these requirements with its Zoned Safety approach. This safety concept eliminates the components and complexity found in discrete safety circuits. Numatics series 503 valve manifolds from ASCO can create up to three independent safety zones within a single assembly that ensure diverse redundancy. They can be configured to shut down air and power only to the group of valves that controls the machine's motion in the operator's vicinity. The operator does not have to shut down the entire machine by releasing compressed air with a redundant safety/control dump valve. Zoned Safety is a simple, user-friendly best practice that reduces component requirements, saves space, and improves design flexibility.
