    Currently trying to troubleshoot Polar 92x,
    Error 469 popped up while cutting (Voltage Fluctuating badly) in which only the clamp will operate, knife was half way down and CLAMPING TIME INTERRUPTED 118 will alarm when knife buttons are pressed. We had the power Authority come in to restore voltage to normal 415v 50Hz, in which it was only doing abt 370-380v, topped up hydraulic fluid, cleaned MHS sensors and at one only cut once and error 469 will pop up again.
    Switched off and manually wind knife back to top dead centre and its showing CUT CIRCUIT INTERRUPTED 132.
    When knife button is pressed the lock disengages but the knife does not operate.
    other.
    hope anyone can assist

    Hi sir:
    This malfunction can be caused by a defective SK95 board. It is quite
    "normal" if this malfunction occurs sporadically.
    Due this:
    Press cut buttons for a longer time.
    - Check SK 95- board, sensors and cabling of cutting cycle
    - Check knife upstroke control, replace if necessary and connect it to +24Volt.
    - Check light barrier

    Thks sir,
    Checked SK95 board cleaned resolder dry joints
    Checked safety bolt sensors light up when open/closed with warning message.
    Checked light barrier which LEDs D3/D4 & D5/D6 both flash simultaneously when cut buttons pressed, without any interruption shows Error 132 & 138
    Where is the knife upstroke control located and to test please.
    Thanks for your reply and assistance.
    God bless
