Bulletin 8883/84 Page 2
The basic building block of the 8883/84 system, the new Honeywell/North American RM7888 controller, carries out burner management. This flame safeguard unit has extensive capability beyond those of other manufacturers and other earlier Honeywell models. With built-in timing and programming functions, it can handle any flame supervision application from the simplest single burner job to the complex requirements of StepFire™ and TwinBed II™. Two levels of video display operator interface are available to accommodate customer preference and need. Complete graphics user interface (GUI) in a Windows™ environment with detailed and dynamic color screens, mouse, and full manual/auto control access comes in the software package with a personal computer to provide the processing power. Also available, but not as elaborate, is a limited graphics user interface. This package provides lower resolution with graphics that are made up of boxes and lines on a monochrome screen.
Full manual/auto control access is provided through function and numeric keys or via touch-screen. As with the full graphics user interface, the pictures can be organized in a hierarchy with an overview screen "at the top" and sub-screens providing more detailed information about specific parts of the process. Either video capability or both can be used to monitor and control a process. As process needs increase, the demands on the operators and desires of management dictate that the more elaborate operator interface become part of the system supplied. Careful design drawn from a long history of experience in combustion processes assures that the system will meet NFPA and insurance underwriter recommendations. A UL label can be provided on request.
