Control (CPU) board
The control board, located just behind the analog board, stores the software which manages the equipment. Moreover, the built in
memory stores the programs used in all models of the Eagle series (please see the bottom note). This board is connected to the
various part of the system, thus allowing the CPU to control the equipment operation by sending the appropriate commands or,
conversely, to get the data concerning the current functioning and process (e.g. possible alarms). The CPU is also connected to the
LCD display board and to the digital encoder.
This control board can be used as “universal” spare part for all the Eagle models because it stores the programs for all of them.
If there is an equipment with such board broken, you can easily replace it just by setting the right model with the
