Anyone got any tips for faultfinding in electrical control systems?

Could you be a bit more specfic, system, manufacturer, voltage etc etc etc.

Well I'm doing a course in Electrical Control Systems and we've an exam in a few weeks on fault finding on the circuit in the attachment. Basically, this circuit controls a pair of cylinders. Cylinder A extends, hits a limit swtich, retracts and hits a limit switch. The cylinder B extends and is detected by a proximity switch, retracts and is detected by a proximity switch. Sequence is complete.

There are 6 relays in the circuit, a timer and 3 pushbuttons. I'm only looking for tips on what best practices are to be used when fault finding. Maybe a website link or something?

Cheers.

Best tip I can give is to be methodical. Analyse what the fault is and then decide where to start looking for the fault in the machines cycle

As with a lot of things, experience only comes with practice. Learn by your mistakes it stops you making them next time

If you can read the drawing then you can fault find.

Follw the lines and you wont go wrong

All fault-finding can be condensed in to six easy steps with a handy mnemonic, Cal Dr C (or call doctor c for the hard of thinking... as in call a doctor, something's not well)

It should go without saying that for you to carry out these steps you need to know how a particular system is supposed to operate, particularly in what order!

Collect - all the evidence available
Analyse - the evidence. You may need to test in order to collect!
Locate - the fault. This is what's actually causing the problem.
Determine - the cause. This is what made the fault happen!
Rectify - the fault
Check - the system

After that it's a piece of **** :O)

Cheers. That's a good synonym. Will memorise that.
