    Troubleshooting with our Heidelbergh SM102-4 year:1999 colours after power failure (block out due to Voltage fluctuations)


    Good Morning Sirs,
    We have a serous problem with our SM102-4 that is ready to start but not start, an arrowed circle around T is marked on the electronic cabinet in CP TRONIC sreen,

    • INIT Test indicates:
    S-SAK FFEF
    S-SLT CON 3F70

    • DYN - TEST
    S-SLT CON FF71

    • Machine failure icon is flashing on Electronic Cabinet as an arrowed circle around T
    • Here are attached screen capture for this issue.
    Can anyone Help me please?

    Best Regards,

    DIDNZU

    Dear Sir:
    Good morning in my country, and Good afternoon in his country
    Your problem with the machine has been done by severe Power failure:the indication by the cptronic
    software indicate Problems:a) SLT-con converter power part Board b) SAK memory analog.
    You must do the following troubleshooting:
    1) Main phase absent, check voltage supply, 2) Mains undervoltage, check fuse 15F1 3) Phase sequence of mains voltage reversed, test for clockwise rotating field motor. 4) +120Vdc from GRM 120 Absent. Check fuse F3 in GRM, Check input voltage of GRM 120, Check output voltages of transforme 15T1. Check contactor 15k48.5) Field circuit connection between SLT and main motor faulty, Check the connection.
    6) Check connection SVT- M1 + Check the connection SVT X16-m1 See the schematic diagram this is for test the fault in the armature.
    and Replace SVT if necessary.
    7) Test the power supplies for SAK Memory Analog +15 and -15Vdc 8) Test the battery back up +3Vdc 9) +5Vdc in power supply for Memory analog
    Let me know any question

    Good Day CHOCK,
    Thanks indeed for your quick reaction.
    Good morning in your country, and Good afternoon in my country.
    You are totaly right, there was a severe power fluctation on Tuesday AM, the voltage on the plant went over 450V, while the normal voltage is 380V in my country.
    1. Two of 3mains phases were absent
    2. Two fuse has blown due to overvoltage while the press was runing in full speed proctuction mode.
    3. I have just controlled the phase sequence and, it's OK
    4. I'm waiting for new fuses supply in order to continue chekings while SLT CONVERTER POWER BOARD is energised!...(I don't have them in stock for now!)
    5. I'm going to follow the schematic diagram and follow all your advices as soon as possible, and will send feedback.
    Your help is very important and too detailed, thanks.

    Regards.

    Good Morning,
    Thanks I'll use my FLUKE179 TRUE RMS DMM, a very kind and too accurate companion!

    The job is Scheduled for tomorrow 8:00AM (GMT+1) in case fuses are supplied (delivery delay too long!)

    Good Morning,

    My SM102 issue was resolved, thanks to every body,
    2 of 3 SLT supplying fuse was broken, we just replaced them and every thing returned OK.

    Thanks.
