Strategy for Servicing

component, assembly, or part of the sync pulse generator.
This manual contains all the information needed for periodic maintenance of the
sync pulse generator (examples of such information are procedures for checking
performance).
Further, this manual contains all information for corrective maintenance down to
the module level. To isolate a failure to a module, use the fault isolation procedures
found in Troubleshooting, part of section 6, Maintenance. To remove and replace
any field module, follow the instructions in Removal and Installation Procedures,
also part of section 6. After isolating a faulty module, replace it with a fully-tested
module obtained from the factory. Section 10, Mechanical Parts List, contains part
number and ordering information for all replaceable modules.
