In the non-volatile memory units (341) of the local control units (34) of the units (3-6) composing an LC system, periodic inspection information, such as the installation date and time and next scheduled inspection date and time, is stored at an appropriate time. When analysis is carried out, in the system control unit (2) that controls each unit, a periodic inspection notification processing unit (211) collects periodic inspection information from each unit (3-7) upon power on or start up, compares the next scheduled inspection date and time and the current time according to a real-time clock (212), and determines for which units periodic inspection notification is necessary. If there is a unit for which periodic inspection notification is necessary, a notification request is sent to that unit, and the local control unit (34) of that unit outputs an indication prompting periodic inspection to a display unit (35). As a result, even if the installation periods for each unit are different and even if each unit is not provided with a real-time clock, it is possible to notify a user when a prescribed period of use has passed since the installation time of a given unit. |
