    Geoff,

    Things get strange but i have some issues we cannot understand!

    1
    on io1 print red L13 + L14 go on when starting haubtmotor!
    its 4c90- relay and 4c100 relay

    but we cant use fast forward> as i asume there is an error somewhere.

    2
    footpedal as you told me we checked was ok but we changed it completely now to be sure it is not the switch but red led 8 and red led 9 dot react anymore?- when removed the clamp plate
    or when pressing footpedal?

    At starting the machine the green led L24 must blink 1 time but does blink two times.
    i made small avi some pictures from the lamps i can upload or send to you

    1: Be aware, there is a LOCK OUT circuits, that prevent 4c90 and 4c100 ( or 4c70 and 4c80) from operating at the same time.

    If you cannot go SLOW, it could well be cause by the NC Contact on the FAST contactor being OPEN when the contactor is not being operated, and preventing the slow contactor from pulling in when SLOW is required.

    ie Check Auxilary contacts on 4C100 (fast Contactor)

    -----------------------------------

    IO Port 2 : L7 (Limit switch clamp plate 1b67)
    IO Port 2 : L8 (foot lever 1b63)

    1b67 P26(pin 15) and P26(pin 4 = -24 supply)
    1b63 P26(pin 24) and P26(pin 21 = -24 Supply)

    Check that you are getting the -24v on the Microswitches
    You may have shorted out the leads at some time, and blown traces on the PA Board where P26 is.

    ------

    GREEN Led IO Port 1 L24 Contactor 4C32 NO
    GREEN Led IO Port 2 L17 Contactor 4C32 NC

    So these two LEDs should NEVER BOTH be ON at the same time.
    (and only time BOTH OFF, should be when Power is not being applied to the cutter.)

    Not obvious why you are getting 2 blinks... suggest you get the other issues sorted out first, and the double blink does not appear to be causing any issues, (but may be a symptom of the other issues you currently have)
