    The blade was down in knife inching mode to clean adhesive of the blade. The powers was turned of to the cutter before the blade was returned to it resting position. Now, when turned on the blade will not return to the resting position. On the screen, it says “safety bolt retracted” Does anyone know how to fix this error?

    Hi sir:
    Please 1)try by hand to carry Up the Knife in the most highest point.
    2) see if the limit switch b22a+b22b if are o.k , dirty, loose wires,or contact burn, or disdadjustment. see the cams are loose of out
    of possition.
    3) if you system has the knife upstroke control and 2 channer Hydraulic.
    in the circuit MHS-MHY Measure +24Vdc+5Vdc for Sensors are 4 cam disk they must stop the knife in upper dead center,test the sensors. The gap from sensors vs Cams must bve 06.-08mms
    4)in the board cutting circuit SK, for Safety Bolt :see if the LED yellow V71 IN REST position will be ON +y72 LED YELLOW OFF When is locked.
