Perfector problem on SM 102

I have a semi automatic perfector problem. Whenever we tell the machine to go into perfecting, it moves to zero position and we then insert the handle to turn the machine. The intensifier pressurizes, but then depressurizes and the machine is locked up. The console says "clamping error storage drum/perfector" and there are two symbols on unit 6 showing red clamps around the cylinder. We clear the errrors, go back to straight and all is fine. We can put the machine into perfecting using the Heidelberg button and pushing the 100 bar icon with no problems at all. It is only when we tell the machine to do it.

Does anyone have any ideas or suggestions?

 

Have you checked if the clamping really release the drum? Maybe the oil pressure isnt sufficient to pull the pin to release the drum, it can cause the clamping drum error

 

On your presure intensifier there are 3 pressure switches. 100 bar, 35 bar and a 10 bar. Most likely the issue is with your 100 bar switch. This is the one that is active when you insert the hand crank. My question is, when you manually activate the hydraulics by depressing the 100 bar icon, does it light up with the 35 bar icon? When 100 bar is activated 2 icons should light up. Are both lit?

 

I too have a perfector issue on my SM102-4P. When the machine goes into perfecting, it moves to zero position and we then insert the handle to turn the cylinder to the paper size mark (687mm). After removing the handle the screen always displays " RETURN TO STRAIGHT" with a red notification, thus unable us to run on perfecting.

Can anyone help?

 

Some times you just need to restart the machine, hope its just that easy . Well anyway you should open the cover where you can see the side of the perfecting cylinder. When you press the turn to straight button watch if the perfecting cylinder released. There usually problem with the oil level in pneumatic pump. It works with oil presure, with not enough oil it will not strong enough to release the cylinder

 

Thanks Andrysetio

I'll check it and revert shortly

 

SM102 has what is called a semi automatic perfector. All that means is you have to do part of the work. once the machine has performed its part, you then need to insert the hand crank, pull the pin and turn the machine to the desired sheet size. If you can do all of those things, than there is nothing wrong with the pressure intensifier so my suggestion is dont mess with it because you can create alot more issues. If after you pull the hand crank and you are at the desired sheet size and the press tell you to go back to straight printing, most likely it is because the synchronization monitor is not correct. Usually the problem is with the flag switch on the operator side above the storage drum. if you dont have any experience with this than my suggestion is to get someone who does. This is a very sensitive adjustment and really you need to know what your doing to get this adjusted properly.

 

Thanks exheidmech

I've checked the switch and found in good condition. I think I need to synchronize the setting again. Do you have a setting sheet showing step by step of how to do it.

Thanks again

 

Atlas, this is kind of a tricky adjustment. First this will require 3 guys. 1 to turn the press in the forward direction very slowly, 2nd guy to read out degrees as the press is turning from the feeder or delivery consols and the 3rd guy to lay under the operator side catwalk and watch the SUM9 module. On the SUM9 module there are 2 leds, one green and one red. First you must find the exact time the red light turns off and then the exact time the red LED turns back on. It should be a window of about 3.5 degrees or so. Next find the exact time the green LED turns on and the exact time the green LED turns off. Should be around 1.5 degrees. The green needs to be in the center of the red LED "off" window. This means that the red LED should turn off, for a few tenths of a degree both lights are off, red LED on for 1.5 degrees or so then red LED off, then both LEDs are off for a short time and then the red LED back on. You will need to adjust the green LED to get it in the center of the red LED "off" window only by moving the sensor not the flag on the storage drum. This is not so easy if youve never done it before and could take you quite sometime. Make sure you turn the press in the forward direction when getting your LED on/off times and make sure the press is being turned slow enough so you can get an accurate on/off time from the guy reading degrees at the consol. Good luck.

 

Many thanks Exheidmech

I'll try it and will let you know the outcome

 

Hello Exhidmech
my guy went under the OS machine and found only the red led which is connected to a reflector.
do you have a drawing showing the location of the 2 leds
thanks for your help

 

The SUM9 module is a small grey box with a green and red LED on it. Its located under the catwalk inside the LVT box that the perfector unit is located in. The red light you are refering to is the dropped sheet sensor in the perfector.

 

Thanks Exheidmech

Have a job on straight printing now and will check it after that. rgds Atlas

 

I am also facing the same problem. I want to know if adjustment process is started when the machine is in straight mode or perfector mode. The problem is occuring frequently during production
