The screen transition system of the screen is selected from multiple screen transition systems, and the function items displayed on the display screen displayed on the screen can be executed in that screen transition system, and in other screen transition systems. This restricts the access rights to each functional item according to the level of various operators such as manufacturers, timer adjusters, end-user administrators, and general workers. This makes it possible to improve safety by making it foolproof. As a result, for example, the operating status display screen that end users often see, the setting value change screen that requires setting changes on a daily basis, and the data display screen that is only checked during maintenance can be separated into separate screen transition systems. The screen transition system including the maintenance screen is executed only when the lock key (-J switch) attached to the front panel of the setting display device is operated normally to prevent erroneous operation. The practice of planning for rain began to be practiced.

Further, by incorporating setting display contents on each menu according to the level of the on-site worker for each end user, the manufacturer can produce differentiated products for each end user.
