Under ideal flow the float should always be very close or touching the proximity sensor, if you can make sure the flaot is right at the top and in contact with the sensor after having done all the previous checks, put a 10k resistance across the black connector after disconnecting the sensor to...

Hello Palgolicho, I do not remember the exact description of the LEDs however after you have made the initial checks like Mathew suggested take a look at the float proximity sensor, the black connector on the top left corner of the picture is where it is connecting, the wire seems to be pulled...

Hello Junaid, some more info might help, are there red LEDs on the SSK boards? What is their status?

At the back of the back plane where the TSK in plugged in there is a flat cable labelled as PF-MON try removing that the next time you're ink zones are locked

The white or something red power plug on the BEK is sometimes the problem, since you have had errors so far apart its not likely that a board is failing, may be the power cable on BEK just comes loose and fiddling around makes it work. The BEK has an under voltage lockout, so next time the error...

A picture of the panel actually help, not really sure if there is a DIPM or just EAK's, could be blown fuses at the power distribution board inside the cabinets, like I said a picture would help.

Azr can works in mode 3, the 24v for the valve comes through that 15 pin connector, its just a jumper from within the connector from the 24v line.

How do you know you are not getting the voltage on the valve, where are you testing this on the bench by yourself? Is it an alcosmart azr can? I believe so because you are taking about 15 pin connector.

The compacts are notorious for locking up due to low 5VDC on the ZSK, usually wiggling the power connectors on the ZSK and the NTM brings the machine back. May be get an electrician to make a plan to change those connectors? 4.8 to 4.9 is low, you are looking for atleast 5.0 v

Hi, that is a very old software, get in touch with heidelberg, they will offer you an upgrade to 32.A, an MC7 IPC, probably a new screen, an eeprom for the REK2, an eeprom for the BEK and probably eeproms for your HAKs.

You might need to go into service and pull out the errors from the auxiliary drives

Bad BEK, REK2 or the communication cable it seems. Also make sure the power supplies are lit up green.

Hi, do you hear a click when the valve opens? If you do valve is good, if you dont its probably stuck, sometimes it possible the person who worked on it installed it the other way around. Pull out the slim longer pipe from the bottom along with the venturi assembly, make sure nothing is stuck...

Hi Chock, I have managed to repair the supply the red light in my particular case was safety shutdown since the 5VDC output rail was at 9VDC causing the supply to shutdown, there were no shorts though, just leaving this out here for anyone who might be struggling with a similar problem. Cheers.

Hi Chock, I have checked there are no shorts, which fuse are you referring to? I have checked all the fuses, the main 16A fuse and also the on board fuses.

Hi, I have an NT33 for a suprasetter, when I try to test the power supply by supplying 220VAC and shorting the remote pins, the fans spin for a fraction of a second and stop, I can hear the power relay come on however it immediately cuts out and a RED LED on the board lights up. What does this...

Hi, I have a display panel for a stahl folder KD66/4 as shown in the picture, the chip marked in the picture is a GAL20v, the chip is shorted and i have no display on the screen. Can anyone help me get the fuse maps for this GAL?. The chip is labelled as 101514 03 U59

what is the condition of the machine now? can you share some pictures? this is the first time you mentioned EAM board burned. are only feeder and delivery screen not working now?

Since you are in Europe the cheapest way is to get in touch with Heidelberg and buy it from there.

the reason you can't access other codes is that the I/O board for the screen itself is dead, which is EAK13
