    Dear fellow printers
    After relocating a 1978 SORM machine I experienced a lot of electrical issues due to a inadequate mechanic who messed up the wirring that was disconnected when separating the feeder from the press.
    Thankfully we managed to run the machine again but still some commads are missing when feeding papper.
    The forwarding belts keep on rotating although a sheet is misfed and the impression disconnects.
    The ranger drum won't feed the sheets unless the impression button is pressed
    Is there a list of commands regarding feeding papper and impresion functions in the machine.what is the sequence and which electrical components perform these operations
    I employed a skilled electrician but he is not totally familiar with the machine

    I am sad, but your situation.
    However i can assist you.
    You have schematic diagram? for this machine?
    Let me know exactly, what are the problem, but indicate what is the wiring number diagram
    Blessing.

    Thanks for your reply, I haven't been able to log in for a while.
    The wiring diagram number is: 100670-3
    The problem still persists. The tapes only stop when the feeder stops the first time and keep on rolling eventhough no papper is feedig and impression is off.
    The front lays operate only when the impression is switched on or if they operate with the feeder the impression switches on by it self when a papper passes through the photocell

    Hi sir.
    need to know what model is your amplifier, BAE ? or Other Weko.
    the year of the machine ?.
    Look for the control Box, and serial number machine.
    After see it his problem, is Disadjustment with
    light barrier and degree, you need to adjust the Control disk in the magnetic switch under the feeder.
    Not need schematic diagram.
    Send me email, for to send some explanation.
    Blessing.

    Thanks for your reply. The control box is Weko old model without LED indicaters.
    The machine is 1978 model
    It is true that the magnetic clutch needs adjustment.
    But also the FEEDER ON and FEEDER OFF functions didn't operate due to wirring mix up. Now they're working with the malfunctions that I mentioned previously

    ok you have old model
    However you must test the Switch ak6(Magnetic switch) test for faulty or Good use DMM
    put some metal between the Switch and Measure for continuity, if there are is O.k iF NOT is faulty,and replace it.
    Attached is there the Block d, for Old weko amplifier. see the Ak6 switch, as did mentioned.
    Of course you must use the common sense for to diagnose if some amplifer is faulty, and repair .
    Let me know.
    Blessing.

    is there one Possible reason. See the Block diagram
    can be another reason TSV 090 amplifier. Of course you must check the Connector, for loose, or dirty, or bad contact
    or corroder, or broken, or cold joint, or dry joint in the board TSV 090.
    Let me know.
    Blessing.

    Dear Sir
    What voltage should be supplied to the ak6 magnetic switch. I traced the connections. I found that it is not connected to the 24V supply in the main control panel.

    Hi sir.
    you must see if there 3 voltages to the Amplifier: 1) 60Vac 2) 5.5 Vac 3) 24vAC
    if you do not have it, any test the Transformer, for Burn or Open . Of course you must measure the Input of primary transformer, for test the Voltage variation, NOT must over 10% up and down. If does, You must install some Stabilizer Voltage, Since you must
    affectation in the Light barrier by the Voltage Variation. Very important
    Finally the Ak6 you must measure the continuituy as I did indicated before.
    Test for faulty or Good use DMM put some metal between the Switch and Measure for continuity, if there are is O.k iF NOT is faulty,and replace it
    Blessing.

    Thanks for your reply
    All the control wires of my machine have been mixed up when relocating the machine.
    The ak6 has 2 thin wires connected to the main control box. What voltage should they be connected to. My quess is 24v and (-). What about the control box itself?
    After establishing the original connections then I will measure

    Ok
    If you are shure you have magnetic switch ak6, the connection is: 3 colot wire bl -4 color wires bl - 5 color wire gr for connection box, or control box.

    Dear Superchock
    We are still working on it. The magnetic clutch is working but some connections between contactors controlling the feeder ON and OFF has been altered.
    Is it true that there is a detailed wiring diagram other than the schematics. One that details all connections between contactors

    I mean a wiring distribution diagram/schematic detailing all the connections between contactors
