Finalizer Service manual
page 3
Introduction
The purpose of this manual is to support skilled technicians in repairing the
Finalizer
The manual begins with a Quick Trouble Shooting table. Here, hints, advice
and possible problems are described.
If the problem is more serious, the next step is to use the Built-in Test Program.
With this program the problem can often be narrowed down to a specific
section, channel or even component.
The next section consist of disassembly and exchange procedures. Please be
aware of warranty rights before disassembling. See the warranty card.
The Block diagram for the signal flow in the Finalizer shows the order of all
the effects.
Circuit description is a brief description of the circuits on the different boards.
A more detailed description can be found in the section Startup Sequence. In a
table the Startup Sequence is described step by step and certain test points are
referred to.
The Startup Sequence is followed by a complete list with test point values, a list
with LED error codes and Jumper settings.
Finally the specifications are stated.
Appendix contains Flow Charts, Schematics, Part lists, and PCB Layouts.
Schematics start with a main sheet, where sub sheets are shown as blocks. Even
sub sheets might have sub sheets. In the Schematics some connections have
label names to help the reader. If a label name is framed, it means that it is
"connected" to another sheet. Label names followed by the symbol "*" mean
that the signal is active low, i.e. RESET*: the reset function takes place when
the signal is low.
This service manual does not contain schematics for the power supply module,
because any attempt to repair the power supply module must be completed
with some safety tests such as high voltage and EMC tests. Hence, it is strongly
recommended that the entire power supply module is replaced in case of
malfunction.
Part lists contain a column called TCcode. Use this code when ordering spare
parts. If the TCcode field is empty; it means the component cannot be ordered
separately. The coordinates in the column Pos. refer to the PCB layout page.
The column named Page refers to page no. in the schematics. In column
comments a short explanation of the function is stated. For some components,
alternative types are mentioned.
PCB layouts are made as gatefolds (fold-out page).
Finally appendix contains a spare part list for mechanical parts.
