Enabling switches PITenable

The enabling switch PITenable is a manually operated control device. It is used when working inside the danger zone of a plant or machine, when the effect of safety equipment has to be suspended (e.g. during setup or maintenance).
It is operated in three stages. In stage 1, the switch is not operated. The machine runs with the safety functions activated. Stage 2 activates the enabling function; the switch is in its middle setting. The machine runs while the protective effect of the movable guards is suspended. Stage 3 is a protective function which brings the machine to a standstill if the switch is suddenly released or fully depressed. This function protects the operator, should he overreact in a shock situation.
