Heidelberg sm52 not run error with perfector

[aktham]

We have installed sm52 but it is not running. the error appeared is "set the press back to straight printing" how to set back it? what is the steps to set it?
model 2000 4colors with perfector
cp2000 v00037

you have to set the press to straight manually. then you should have a message to clear out on the console.

You need to operate the hydraulic valve that releases the drum storage, drum storage lead to the mechanical zero position. Then the other hydraulic valve of the rack and take it to its mechanical zero position is checked with a gauge of 5mm. then restart the machine and have to leave the error, if the problem persists write me again.

Really not a good idea to manually activate the hydraulic valves on any fully automatic perfector like an SM52. Reason, because there is a 4th hydraulic piston that activates the drive clutch for the perfector positioning motor. This clutch has pins in it that line up only one way. Activating this clutch in the wrong position will force these pins into the oposing clutch half under hydraulic pressure, almost 1500psi. This will almost certainly damage the clutch. Anytime you get the message to set press back to straight printing, there is a couple things the operator needs to do. First go to the printing material screen and press the green check mark if it is lit. The press may move slightly. Next use the hand crank to manually turn the press in the forward direction (counterclockwise on SM52). The press should turn easily at first and eventually lockup. Remove the hand crank and pull out the spindle. Go back to the printing material screen and the green check mark should be lit once again. Press the green check, once for the saftey beep and again to move the machine. It may not look like the press is moving but the perfector is recalibrating itself. If you go to the unit before the perfector you will see it moving extremely slowly. Wait for this process to finish, usually 2 or 3 minutes. Once it is completed you should be good to go. If the problem continutes than likely you have a sensor out of position or not working at all. This process will at least allow you to run the machine in straight printing.

Thank for everybody
exheidmech thank you so much i did what you write 1st step was well and 2nd step good but this process not finished i was waiting long time there is a clock sign up to the screen at the first its color green then yelow and the check mark isnt lit again and no any moving. this status dont change until i restart the machine after restarting the same error. find attached pic.

The fact that you are getting a storage drum clamping error tells me that you may not be getting any pressure out of your intensifier. Either your intensifier has lost some if its hydraulic fluid or the intensifer hydraulic line has become unplugged. The intensifer is located under the catwalk bolted usually to the second unit. You will need to crawl under the catwalk, maybe even need to move a pump or two around and maybe even have to push some wires away from the intensifier. There should be 1 air line plugged into it, its blue. Make sure it is not kinked or crushed. There should be 1 orange line plugged into it. This is the electrical connection to the press. Make sure it is properly plugged in and not damaged. There is also 1 black line plugged into it. This is the hydrualic line. It is connected via quick disconnect and secured with small zip tie. Make sure it also is not damaged, no oil leaking from the line and properly plugged into the intensifer.

Hi,

My speedmaster SM74-6 PH 2001 is having the same problem. Monitoring of Reversing Cylinder- storage drum synchronisation error.

We have noted that the sensor as per attached image is damaged. However is there any way despite this to engage the press in straight mode until I get the sensor?

 

[Amir Mohamed AmirAli]

Steps were followed however we are still receiving the following error as per attached image.

Hello I’m having the same problem on the sm 52
One of the places oil was leaking on the machine
From the pressure intensifier so that’s got to be fixed
So how did others solve thier issue
Thanks

 

[Sunilvaryani]

The error is showing p 21
Thanks
Sunil

Dear sir
We have changed the seals on the machines perfector
Parts on the machine, but still the oil goes down
What could be the reason for this
Thanks
Sunil

What seals did you replace?

 

[Sunilvaryani]

The blue seals on the hydraulic valves on the
Machine round hydraulic valves

[Mark Fisher]

How many of the hydraulic pistons did you change the seals on, there are 4 in total?

 

[Sunilvaryani]

Yes we have changed all 4 now oil is not leaking
Thanks

 

[Sunilvaryani]

The problem we got is that machine encoder
Is set at 79.54 degrees n the perfecting encoder
When we do the change over is going to 89.03
It’s supposed to stop at 79.54 even after setting
The perfecting encoder could it be faulty

My problem with pm 52 not solved someone pls help
P21 error
