15. All controllers, including those assigned to data processing, shall be same model and series. 16. Controllers shall be the current generation product that will be supported by the manufacturer, with parts and service, for a minimum of ten years from time of installation. 17. All controllers shall be mounted within specified control panels. 18. Examples of acceptable controllers: Hays-Cleveland Station”, “AC MicroMod 30 ML”, Moore 323, Preferred III”, Toshiba “Mod “PCC “LC500”. C. Supplies: Provide separate uninterrupted power supply for each boiler controller. Any signal that is common to all boilers, such as plant master control signals, shall be isolated from all other boilers so that failure in one boiler circuit will not affect other boilers. SPEC WRITER NOTE: Include the following paragraph if touch screen operator interface is required. D. Touch Screen Operator Terminals: 1. Provide one touch screen control station and display for each boiler mounted on the boiler control panel. Touch screen shall be in complete communication with all controllers associated with the boiler and with the burner management system. Provide alternate control station to replace touch screen control functions if touch screen fails. 2. Control Station and Display Requirements: a. Local operation and programming of controllers, graphic display of information, alarm message display, historical and real time trending, remote controller tuning, x/y plots of fuel air curve data for intuitive commissioning of controllers, Ethernet connectivity and standard Internet browser remote communication. Network to boiler control and burner management systems. b. Selection of automatic or manual control of firing rate. Local manual control to increase and decrease the firing rate. c. Indicate burner management control status and diagnostics in English messages: control on, for ignition, igniter flame signal, main flame signal, post purge, burner off, all diagnostic information available from burner management system, continuous indication of flame signal.
