Finalizer Express Service manual
page 3
Introduction
The purpose of this manual is to support skilled technicians in repairing the
Finalizer Express.
The manual begins with a Quick Trouble Shooting table. Here, hints, advices 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. Refer to the warranty card.
The Block diagram gives a quick overview of the signal flow.
Circuit description is a brief description of the circuits on the different boards.
LED error codes and Jumper settings are described on page 12.
Appendix contains Schematics, Part lists and Component Layouts.
The 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.
Part lists contain a column called TCcode/ Item no. Use this code/no. when
ordering spare parts. If the 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.
Some PCB layouts are made as gatefolds (fold-out page).
Finally appendix contains a list for mechanical parts.
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.
