    Good day Sir
    Hope you are well.
    Please take note of this: 1) Test the switchs 1 S35+36 +1S19+1B18+2S60+2S31+2S62+2S38
    2) This switchs send the signal to the respective Board EAK and others
    3) Test the Valve 15K64+NY15+NY14 Thist control the supply unit of sheet turning device .
    4) Test the switch-valve hydraulic nB41+NB33+NB34+NB40(Oil level Hydraulic see if there are enought oil, and try to see if there are clean and free of dust or debris in the system. Any dust or debris will have problem.
    5) Lock for loose connector or leak problem in the system. in The electrical swtich look for continuity and clean contacts very well, look for loose wires, and oil in the contacts.etc
    Let me know.
    Blessing
    Happy New Year.
