I have problem in HAK_02 (7FFB)

I have problem in HAK_02 (7FFB)

 

What is the problem in the machine really - can you explain the nature of the problem and what type of machine is the problem on?

 

Pour le code HAK 7FFB :
La fiche du moteur est retirée, le retour du signal du capteur à effet Hall est impossible
Donnez-moi plus d'informations sur le problème

 

I had several issues in SPK and there was a voltage drop across the battery in the SPK card and it was fixed, but when the machine is turned on and the moment the paper enters the machine stops. The machine is a speedmaster with two 70/100 print heads
Thank you

 

Can you take a video for me to clearly see what's going on?
Does the problem start when the feeder table is raised?
Are there any errors in the initial test??
Enter the service menu 1 then click on the icon mentioned in the image:

and send me the HAK card status to see.
Let me know
Good luck

 

I took photos and the errors appeared as follows:

 

You must first make sure that the HAK card is properly inserted
The start-up plausibility test gives you a problem with the HAK which means a motor at the feeder or at the receiving end is poorly connected or defective.
It is also necessary to check the retarder motor and the capacitive sensor on reception.
If you can take a video for me from the start of the machine until the problem it will be useful to approach the solution of the problem
Again if you can replace the HAK 2 card with an identical card it will also be useful to ensure that your HAK 2 is in good condition.
If you will need other information you can contact me on my whatsapp +212700552467
Good luck

 

I replaced the water motor, the first head with the second one, which did not work, which assured me that the faulty water motor did not work. I will repair it and provide you with the results.
Thank you very much

 

In all heidelberg machines, at start-up, a plausibility test is carried out which ensures that all the components are in good condition before putting the machine into production, and if a component is defective, a signal return is not immediately made. Control board gives an error message.
If you will need more information please do not hesitate to contact me on my whatsapp
good luck

 

When I replaced the water engine, the fault changed on the control panel, which proved to me that the malfunction in the second water engine was going to me with the details after the repair on WhatsApp.
Thank you very much

 

Excellent work
Good luck, if you need any other technical information, do not hesitate.

 

I did not hesitate to ask for help
thank you
