WHAT IS THIS AND HOW DOES IT WORKS ?

IT IS A MICRO PROCESSOR CONTROLLED SYSTEM , A COMPUTER !

IT WORKS LIKE A COMPUTER (MORE OR LESS) AND THE PROGRAM IS THE SAME IN ALL UNITS !

WHAT IS ON THE

EPROM

In each panel there is a program:

•Local Panel 1 = Local Panel 2, and contains the Water level controller, Oil and Air controller, Burner Set points, etc.

•Power Panel 1 & 2 contain different things, and depending on the plant set up some, or all, of the program is used.

•All Panels (micro processor units) are talking to each other.

THE EPROM CONTAINS THE PROGRAM FOR:

•LOCAL PANEL 1

•LOCAL PANEL 2

•POWER PANEL 1

•POWER PANEL 2

•BURNER TYPE

• AND OTHERS

Basic Functions:

•Steam Pressure Controller

•Oil / Air Flow Controllers

•Atomising Steam Controller

•Water Level Control

•Oil Pressure (Ring Line) Controller

•Oil Temperature Controller

•Alarm & Shutdown Functions
