This could also entail assessing the present state of any or all equipment as to the present age of a system, i.e. is the present installation of a certain age that will benefit from an upgrade or retro-fit, for example, consists of large hard-wired electrical components and cabinetry that are very laborious and difficult to diagnose any maintenance problems.
A possible solution would be to implement PLC control systems and train maintenance personnel in the use of the equipment in order rapidly diagnose problems and to cut down on assembly line down times.
To replace failure prone AC solenoids through-out the system with the DC variety which are much less prone to such failures.
Just for a few.
