1.1.3 Maintenance Philosophy
The fault isolation and maintenance sections of this manual provide a
logical path of fault isolation and repair designed to return the equipment
to proper operation in most cases. The fault isolation procedures for the
equipment end item have been broken into two sections, which lead the
technician to maintenance procedures that he/she can reasonably be
expected to perform.
The criteria for separating fault isolation and maintenance procedures into
two sections can be defined by Class 2 and Class 3 repairs. Class 2 repairs
only require the technician to replace an end item subassembly or easily
accessible component (e.g., a fuse) in order to return the equipment to
proper operation. Class 2 repairs are applicable to situations in which tools
and/or experience of the technician are limited, or time does not permit
extensive maintenance. Class 3 repairs (identified as
Shop Only
) involve
in-depth repair to subassemblies that have been identified as faulty. Class 3
repairs are applicable to situations in which tools and experience of the
technician allow for more extensive procedures. In some cases, even
though a technician may have the ability and resources to perform
extensive repair, he/she may decide to replace the entire subassembly in
order to return the equipment to proper operation more quickly. The
subassembly could then be repaired at a more appropriate time.
It is extremely important to note that while many of the commonly
identified solutions to equipment failure are provided in this manual, it does
not cover all possible situations. Contact the appropriate Vari-Lite
Support Group if you have questions or if the procedures given do not
solve the problem.
