There is hardly a home or business that does not hve some kind of a network in place or wants one or has one that needs some tuning, repair or other service. But the problem is that in this day an age there are too many network "experts" and "gurus" that have mystified the whole process and for any network service at all, you have to hire an expert and have to pay for an evaluation, estimation, diagnostics and a whole lot of other formalites before you can get anything done at all!

At CITS we make everything very simple and straight forward for you. Simply call me directly and I will fly out there and do whatever you need done at your site. All you will be paying is the cost of travel, the air fare, hotel and my per diem and then a simple labor rate of $193.20 per hour, that's it. And of course the cost of materials. Who does that nowadays? Please ask aound and find out. Obviusly I am not looking to get rich here at this point. Just to keep busy and do YOU some good! That's all. Please don't fall for that high sounding network lingo and trust my experience. I solve problems just standing there!!

Remember, the good Microsoft and other great vendors may have invented and put the network systems in place in the first place and the network gururs are great people but they will make you go thrugh a very formal and stiff process. Whereas I will get it working informally and completely before they will figure out what to do even! And I will figure out and setup the network design without even using a piece of paper and pen! Well, may be a pen and a notebook. But I will give you a write up after all is setup. Don't worry there will be some documentation!

My number is (651)442-9044 and is almost alway ON. I am looking for a PROBLEM to fix!

And I forgot to say, I work on networks Small or Lage, at home or abroad. Nothing is too small or too big. I have not said "NO" in my life yet!

Thank you.

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.


Objectives             Upon completion of the course the student will be able to:


·         Describe the hardware components of the XBS Central System

·         Exhibit an understanding of the function and purpose of each Hardware Module

in the XBS System
