Brief                      The focus of the course is basic hardware maintenance and basic trouble shooting on the Excel 5000 controllers.  Every topic is presented with this intent in view. 

The course starts with an extensive block diagram of an XBS System and its extensions and enhancements. Students are encouraged to relate the discussion to their own systems and to bring up any points that they may need clarification on.  This module of the class is basically an overview of system components, application programs, hardware modules, XI581/XI582 operator units, XI584 Operator and Service Computer and Honeywell CARE Engineering system.  A brief session is provided on operator unit operation.


The next module of the class is a technical description and discussion of all Excel 500/600,Excel 80/100, Excel 15,Excel 20, Excel 15,Excel 50 and the XM100A Modem Module controllers.  The purpose of this module is to prepare the students for maintenance work on excel controller hardware.


                                The next module goes into controller commissioning and startup.  Application load/dump, and setting up parameters are

also discussed. Controller and bus communication problems are analyzed.


The course also covers interpretation and analysis of the site documentation prepared for the customer by Honeywell or other engineers.  The course culminates with test and checkout of the Excel Controllers using the test and checkout program, Excel Test.  In particular, test and checkout of the controller inputs and outputs is discussed thoroughly.
