To provide staff with effective protection from hazardous energy sources you can introduce measures in the form of a LoTo system. These guarantee that machines and other work equipment are isolated from the energy supply, whether electrical, mechanical, hydraulic, etc. That way you can be assured that an unintended restart is excluded. http://www.pilz.com
The LoTo system from Pilz comprises two stages: LoTo analysis and LoTo procedure development. As part of the LoTo analysis we examine the existing documentation, such as the plant’s LoTo policies and the procedures for preventing re-energisation. This is to ensure they meet your own internal corporate requirements. Once the LoTo analysis has been successfully completed, we develop a detailed LoTo procedure for the specific machine, in graphic form. This describes the individual requirements step by step. As a result it is guaranteed that all hazardous energies are controlled through the lockout/tagout procedure.
