Hello all of you!!! I have problem with program for concrete plant(CQM1H CPU 51,ID212 x1,OC222 x2,OC224 x1,AD042 x2) and need help from you.
Before reconstruction concrete plant have extractor belt for weighing and transport agregates to skip-agregate transporter to mixer- (4 agregates separately dossage on weighing system on extractor belt - 4 cells ),
and after emptied belt,
belt stop,
skip go up to mixer.
When skip go up, agregate dossage go on to belt and waiting for skip to go down etc.
Old automation with CQM1H CPU51 suport these system.
Now, after reconstruction we removimg belt and put 4 cells on skip and agregate dossage go directly to skip weighing system.
Here is the problem- agregates,cement ,water and aditives dosing corectly- but skip wouldn't go up.
We tried to do changes on program but nothing.
I send you images pieces of old program and maybe you can help me, and if you want contact me on PM and I can sand you all program.
-input signal when belt start after dossage
- input signal skip down (limit switch)
- input skip waiting (limit switch)-stop skip before mixser finish mixing
- input signal skip hight limit switch(emptied agregate to mixer)
- skip UP output
- skip DOWN output
- belt output (when finish agregate dossage)
- conditions for skip up and down
Please help me!!!
THANKS ALL OF YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
