Man Roland 700 Non Permissible Feeder Pile Movement

I am working on a Roland 700. I was facing the feeder non permissible pile movement up and down problem. I checked in the k001,002,003,004,005 contactors. Everything is ok and I checked the motor - also ok. Can you help me to find a solution for this problem?

 

K005, auxiliary contact...

 

I check the auxiliary contactor also that is also ok,but the problem is not solved

 

I was checked that contactor also that is also ok,but the problem is not solved

 

Did you check input card?

Adjust the brake

 

How to adjust the brake

 

It is written on the brake.

 

The problem is not solved. I am thinking it has some other problem. Do you have any other idea?

 

check input cards and safety relay board (slot 2)

 

Thank you, the problem is solved

 

Can you tell me about B814,B815,B817 sensor, and each sensor is indicating which one is forwarding or lifting suckers. How can I find out if the sensors have any problem?

 

these sensors are for suction head height control and B814 or S814 is for pile control via press foot, you can check the signal in the RTR computer rack

 

It would be nice to share how the problem is solved.
