Accsess Procedure
Begin with this procedure when you have identified which module to remove
for service.
1. Find the module to remove in Figure 6–2 through 6–5.
The title of the figure indicates whether the module is an external, internal
module(1), or internal module(2) part.
2. If the module is externally mounted and no internal access is required,
remove the module. Follow the steps in Procedures for External Modules on
page 6–17.
3. If the module is an internal-chassis module and access is required inside of
the instrument; do the Line Fuse and Line Cord procedure followed by the
Cabinet procedure. Both procedures are in the Procedures for External
Modules subsection.
4. After completing those procedures, return to this procedure and continue
with step 5.
5. If the module is an internal module(1), access the inner-chassis.
a. If removing the output assembly or display unit, first do the Trim Ring
found in Procedures for External Modules (page 6–17).
b. Find and do the procedure for the module to be removed in Procedures
for Internal Modules (1) on page 6–30.
6. If the module is an internal module(2), access the reverse side of the chassis.
Since the module is assembled by three classes, perform the following steps
in the order listed.
a. Find and do the procedure for the module you want to remove in
Procedures for Internal Modules (2), page 6–44.
b. Do the procedure A10 Connector Board found in Procedures for Internal
Modules (1), page 6–30.
7. Install all modules previously removed. Read the module removal for service
instructions found at the end of the procedure. These instructions will guide
you in installing all modules previously removed.
