Diagonal adjust

I have a problem on SM102 model 1990 with cpc1-02 machine registration diagonal problem during running, operator told me the registration on tail end of the sheet is moving especially when i use diagonal registers.. are there any ways to adjust this manually? I also have a new diagonal servo motor I don't know how to adjust to check if the error from it or not

 

Plate clamps are manually moveable, even on presses equipped with diagonal register from console.

 

Thanks for your reply
The machine equipped by diagonal motor xm6 ,there is no stuck with motor also it moves from console but we think that the internal potentiometer not adjusted or the motor have problem
running a sm102 year 1990 .are thrid unit is almost always maxed out in its diagonal register. I need to know if diagonal motor xm6 adjustment to its zero or not ?how to fix the problem.?we have checked the plates and its good and the operator told us the problem from diagonal

 

The pin located in between the cutout in the plate cylinder bearing flange should have an equal gap, both sides of pin, at "x" readout value. I'll give you the number after i see 5,000 in bitcoin deposited into my account. I jest. I'm looking for the value.

 

Thanks for your reply
I appreciate your concern

I don't know meaning of the following
1 cutout
2 bearing flange
3 readout value
