What kind of equipment are you next to?
It’s what we call a suitcase Process Control trainer. It gets installed in a wheeled case and can be adjusted by a teacher via a computer link to ‘fault’ in certain ways so the student has to troubleshoot the system. We make larger units of this, also. It pumps water and the flow is controlled in different ways.

I assume these are made to sell? We have 2 groups in my department that do process control calibrations and maintenance.
 
Halloween costume contest update, I came in 1st place and won a $25 Kroger gift card. 🙂

And in keeping with this thread here is something I found funny in a recent financial seminar mailing. Apparently they are catering to a varied clientele.

Congrats!
 
Those are great learning tools. In particular the ones that allow faults to be added in. IMO thats a great way to teach troubleshooting skills
And to test troubleshooting skills.
When I was in the military, I drove a jeep, I waited on the crew, I read the handbook. The troubleshooting guide said
"If jeep stops & will not crank, check the gas gauge first."
 
I went to a training class for radiology equipment and the instructors would bug the systems for us to troubleshoot.
Sometime they had circuit boards that had known problems and sometimes they would just put tape on one of the edge connector pins.
A lot of guys wanted to just look for taped connectors. They didn't learn a thing.
Once we had a problem and in the course of troubleshooting we shot around 50 X-rays.
The instructor had screwed up and we destroyed an x-ray tube. Those are not cheap.
The next class was on how to replace and calibrate a new X-ray tube.:oops:

Yup. Tape on pins is what instructors did for us.

Pulling boards and looking for tape wouldn't work for a kl-10 mainframe computer.

Chasing gates was the only option.

Oh, wire-wrapped backplanes - there's no school like the old school! I cut my teeth on a Cyber 170/720 designed by Seymour Cray. Fortunately, diagnosing problems actually got easier from there.

To keep the 5hread on topic.

Sea story time

After graduating from kl-10 school I was scheduled to do the maintenance on Sunday night at midnight on the 7 mainframes they used. That involved checking fans and voltages. An experienced engineer was also there in the event there were problems

While checking the 24v supplies I shorted the 24v to the 5v buss. o_O I went to fetch the experienced guy who was sitting in the lunchroom. I told him I screwed and he replied;

"You broke it. You fix it."

I ended up having to replace 7 boards I had blown out. But I did finish before 8AM so all was well.

Which reminds of an off color joke that poked fun at IBM engineers. The punch line was the field engineer on his wedding night saying;

"Don't worry I will have it up by morning."

:rolleyes:
