    Hello dear sir, I can say that the problem is not at the level of the card since the button of the feeder lights up but the clutch does not engage.the problem must be at the level of the oil of lubrication of the machine or the air or a safety.I like that you check if there is light oil in the jar of lubrication.I would like you to check if there is light oil in the lubrication jar. If it is grease, you will have to turn off the machine then mix the grease with oil until the grease becomes light, then turn on the machine and run it for at least 5 to 10 minutes and try the feeder to see if it is not good, then check the amount of air received by the machine.
    I am waiting for a return to continue the research thank you very much.

    Sir now the lubrication error is OK but still have problem. The feeder clutch is not working. I also check the voltage on VSM2 board thire is input voltage available 24v dc. +1and69 but output nothing. I checked the voltage +1and VSM2 board output point no 3 their is no voltage

    Hi sir:
    If you do not voltage at coil of clutch feeder for + 24Vdc, measure the continuity for the FUSES Before to bridge rectifier 24Vca, F10+ F11+f12+f13+F14+ F15.!!, FOR faulty, loose, false contacts, or corroded, or OPEN...! or course the Bridge rectifier can be faulty too, measure it. !

    There next, see if there's any interruptions on lines, connection, loose wires, faulty wires, or dry+ Colder joint solder in the board!!

    2) contacts faulty,and replace it, that relay or contactor.

    Blessings

    Hi sir I checked the continuity from 11X1To 1.15EVM3 XEA there is that is OK. But I have one question how can I check the input and output voltage of 1.15EVM3. Please help me I have wiring diagram I will attach the some pictures. Thank you so much.

    The best way is to see, if the push button is with LED =ON.
    Otherwise test:
    1) continuity with the push button, turn OFF, the machine, and do it with DMM.

    2) if there are continuity, teste voltage in the input push button, if there are, test the output voltage push button, and see if the clutch Feeder working.

    3) if there's Voltage in output push button, and the clutch Feeder : Not working, possible defective coil of Clutch overheating or Open or In Short circuit, or ground to the chassis.

    Good luck, and use : " common sense" , the best invaluable tool: x troubleshooting.

    Blessings.

    Yes sir when I press the BUTTON LED light is on. I checked the continuity of the push button that is also OK. Yes sir the clutch is OK before we check. We give the voltage directly that time is working. Sir the input signal is going to 1.15EVM3 XEA but I don't know how to check there the voltage in 1.15EVM3 out put.
