    Very likely your problem with SEK and blue malfunction is the guards on the drive side delivery. Make sure they are closed properly and make sure that the magnetic switch on door is positioned properly with the magnetic switch it matches with when door is closed. This is quite common on older SM52 due to the fact that these doors will sag over time making a misallignment between both halves of switches.

    Delivery problem is most likely the eye or sensor in delivery which limits pile upward movement. Make sure this eye is clean. A dirty eye will not allow pile to move upward. I cant remember if this eye is located on Drive side or Operator side but it is imbedded in the side frame slightly and is glass. Just wipe it off with a dry cloth.

    Hi exheidmech,
    Thanks for your reply, I checked the door and it closed well.. And when I opened it the fault become red not blue and it appear on Cp 2000 that it is open... But the strange thing ... It is closed and it show on cp 2000 by blue? What is the different between blue and red fault?

    And for the delivery pile I checked the eye, and it is ok... And measure it and also it is ok ... there is any thing else to check?

    Thanks for your support...

    Does the SEK error appear at boot up and go away when you acknowledge it? There are two connections going out of every safety switch, one goes to EAK and other to SEK, when the safety indicates a blue malfunction that means signal going to the SEK is disturbed where as it is displayed in red when the signal to the EAK is disturbed. What is keeping you from running the machine? can you post a picture of the errors? May be you can go into diagnosis to check?

    About the delivery sensor can you check if it giving any ouput? I would recommend to trace the wire going to the LVT box remove it's output pin and then check the pile may be the sensor is already shorted out.

    apologies for the late response, great to know you traced the problem and solved it, what about the delivery pile? has that been resolved as well? I am not sure about the double sheet detector at the sidelay, normally if its malfunctioning you can turn it off since there is already another one ultrasonic double sheet detector just at the infeed, if you are sure there are no double sheets then you can try turning off this sensor and try to run the machine, be very careful when doing so and be sure the double sheet at the infeed is working.
