Thank you all for your suggestions.
Apparently there was no snubbing in the circuit and the flyback voltage was turning on the SCR's, I added a 0.2 ohm resistor in series with a contactor in paralel with the motor, so , when the electronics remove the trigger to the SCR's the contactor connects...
My customer has a SLITTER which is very old, it has a 75 hp RELIANCE dc motor.
Motor starts and runs fine, speed varies as you adust the potentiometer; The problem is when you flip the switch off, motor speeds up for a couple seconds and the amperimeter goes all the way to max 400 A.
DC drive...
Well congratulations on your success. :!:
The code you're showing for "tenseconds" function seems ok.
I think you might have a problem with your power supply, because the only way for the PIC to go back to the first loop is by means of a RESET, or a power cycle. I think that when you turn your...

But what if someone wants to go back, you will...
very good, I understand.
Do you have an oscilloscope?
When you run the code what happens, does it respond to the button presses?
Does it show anything?
First thing I see is that you have two instances of while(1).
I don't see why you would have while(1) in void manualmode, in this case, once you call void manual mode, it will never return.
Would you like to tell me in plain words what will your design do?
PS: Don't worry, I'm downloading...
I've revised your code and I don't see where in the main execution branch you call the timer initialize function.

I'd like to see the whole code.
I saw the program...
1- if you look at the program carefully, the while(1) is used only once in his program.
2- while(1); //Sit Idle Timer will do every thing! ; this means that he don't want to do anything in the main loop, if you look at the program flow, he initializes and then puts the...
Wait a second, if you insert an infinite loop in a timer initialization routine, it will never execute anything else, not even the interruption because you will keep initializing it.
You should only have one, in fact, only the main execution loop as an while(1) infinite loop.
Ok pal, this is the way I understand it, it's written in my own words and I'm open to receive suggestions and corrections.
Well, as I see it there is a lot of theory about harmonics, yet if you have any doubt, any music tutorial will provide you with practical evidence of a main tone and the...
If you're using the LM324 you shouldn't have problem using it with a "single supply", I use it to receive analog input in my projects and I always use it in single supply mode.
you just have to keep your sensor signal in the positive side, remember, with negative input the opamp(output) will...
Hi, I'd like to be your friend...
I'm an industrial electronics engineer, hardware, software and firmware designer.
I study chinese.
I own an industrial automation solutions company, and I might be interested in your products.
