A milestone in machinery safety

A milestone in machinery safety As part of its machine-guarding programme, Banner Engineering has introduced Pico-Guard, a new fibre-optic safety system that directly replaces mechanical safety interlock switches to safeguard potentially dangerous machines. Pico-Guard is versatile, efficient and easy to install. It combines a controller and various plug-in, snap-lock Pico-Guard optical safety interlock switches and plastic fibre-optic cable to monitor doors, gates, and hard guards. It eliminates the need to run electrical wiring to the machine or hazardous area. Durable fibre optic-cables can be easily routed to multiple machine guard points or hazardous areas, making conventional copper wires that carry electrical current to the guarded points no longer necessary. In operation, when the system detects a break in the optical beam (absence of its signal) such as the opening of a door, or receives a safety stop request, it provides a stop signal to the machine control circuit to protect personnel from hazardous equipment. However, the system does allow for some degree off mechanical tolerance in hinges and door alignment, thus preventing nuisance tripping. In addition to personnel protection, the system can protect equipment, critical tooling, or other critical materials in process. Additional flexibility is provided with the patent-pending Universal Safety Stop Interface (USSI). It allows two or more Pico-Guard controllers to be connected to control a single machine when required. In addition, this interface permits other safety devices such as light curtains, E-Stop buttons and rope pulls to be connected to the controller. This makes it very easy to integrate many safety functions into one controller. Each controller has two of these very useful input connections, one latching output with manual reset and a trip output with automatic reset. The Pico-Guard is ISO 13849-1 (EN954-1) Category 4 approved.
