SM52 varient codes

Hi all,
Can anybody help me on setting the varient codes in SM52? This is non cp2000 model and without cpc.

I see two buttons underside of the delivery operator's panel. But not sure which to press.

Great help if anyone can guide of through.

Thank you.

 

Hi,
What is the age of your machine? What is the configuration, how many printing unit, standard, High pile or Extended delivery? Send a photo of variant codes and explain what the problem is. Changing variant codes need experience and knowledge, without them you may make the condition worse.

Good luck,

 

Hi Mathew.
Thank you for quick reply.
Machine is SM52-2 standard delivery. SN 201551.
This machine was recently imported. And when it turn on it freezes at the Heidelberg logo. And my observations tells that the machine is acting like somebody had done a basic initialization with only jump the pins 11 and 12. Since I have a previous experience in such cases, I've tried a basic initialization with jumping the 9-10 and 11-12. But it seems the machine is not completing the task. So I observed all boards add all the LEDs which should blink in the normal operation, are blinking correctly. And the MID display is also normal.

The purpose I've asked about the varient codes is, I suspect the NVM card. So in case NVM card is the case, I need to put the varient codes back after the replacement. (I have such previous experience with SM74-2 but not with the SM52-2)

And your advice is highly appreciated.

Thank you

 

Hi Nimesh,
Now the task is clear. I believe there is no issue with variant codes since machine has not initialized properly. Variant code variations only cause in the press functioning. I recommend you to check the connectING cables. If +24 is shorted, you may get same problem.
Check wiring installation and come back to me.

Good luck,

 

Hi Mathew.
Thank you,

I've already checked the power rails, the 5v, 24v, +15v and -15v from the EWK1 test points. They are all within tolerance. And I've checked with another NVM. Seems my suspect is wrong. The result is the same. Since the problem is not with the NVM, my need to change the varient codes goes away.

Strange thing is the MID is working. And it's showing an error in 12 (delivery) but the KID keep on showing "heidelberg". Without the jumpers, some LED s on the delivery operator's panel are blinking. (Just like when you Accidentally jump only the pins 11-12 on a machine with KID) and with the jumpers on pins 9-10 and 11-12, only the display shows "heidelberg". No LEDs blinking on the delivery panel. Even the pneumatic compressor is not turning on. But the LEDs are blinking on the ZSK and EWK1 and 2 as normal. Very strange.

 

Didn't you make mistakes in connecting flat cables to LVT boxes?

 

Hi Mathew,
I'll double check the cabling and let you know. And also I'll check the wire continuity of the flat cables too.

Is there any way to check whether there is a communication failure between ZSK and KID/EAM?

Thank you

 

Two cllor machines are delivering on one chassis and any unit of machine will not dismantle during shipment. I have seen several times EAM, interface between ZSK-KID (X4) or ZSK-EAM (X18) have got some issues or IC is burnt up. The easiest way is to check EAM and KID on another machine but ZSK is tricky.
