After the machine is overhauled or stopped, it needs confirmation before it can be restarted. You are the boot operator, that is, the machine can run normally immediately after boot. Actually, it's no big deal. Before starting the machine, it is necessary to check whether the work of various departments related to the equipment is in place, such as the maintenance team, whether any problems were found during the maintenance, and whether the instrument department found any problems with the equipment and instruments. Anyway, it's about the same as confirming the position, and then turn it on.
