Consistency

The system could work 24 hours a day, 7 days a week, 52 weeks a year. As long as the upper feeder system had enough raw materials feeding into it, it would never stop producing product.

Which is not to say that it was all on, all the time. Parts would break, aspects would require changing, maintaining the device needed downtime.

So it was modular, parts could be turned off, removed, fixed, while the rest of the machine worked. There was always something off or removed.

But saying the machine was off 24 hours a day, that seems wrong, somehow.
