Assembly of major components and internal components
fig. 2-1 shows the exploded view of the different internal components of the Master Unit of the EnCal3000
Quad. The components in the slave unit are in principle the same, except that, the pressure regulators for
each stream and the processor board are not installed because they are only needed in the Master Unit.
The frame is used for mounting the components. It allows the removal of all the direct and individual
components, with the exception of the interconnection board. The components can be removed directly and
individually by unscrewing just a few screws.
If the Interconnection Board must be replaced, the frame has to be removed from the enclosure base first.
This arrangement permits the service engineer to easily review the board in case malfunctions would occur.
The detailed description of the functionalities of each component will be done in the following paragraphs.
