fit lockout device to door so before entry padlocks have to be fitted to keep door open and disable system.

as a back up movement sensors could be used in case operators bypass lock out then anyone moving in the room will be detected

Thanksinadvance,

Welcome to the site. I wonder if your facility can afford the risk I see in your suggestion. At the same time, I understand your desire to minimize "nuisance" trips. Interconnecting the settings and the supposed presence or absence of personnel doesn't seem to be wise, in my thinking. Over time, the reasons for the interconnection can be forgotten or be viewed as unimportant or be seen as a nuisance. The settings you use should be for safety to the equipment and processes the equipment serves. Arc flashes represent the energy released in a fault condition, not the "cost of doing business". I feel that you would want breaker settings that are protecting the equipment---all the time.
