    Hi,

    Try to disable the Brown-out reset circuit.

    My initial routine is not reliable because I guess the following happens:
    1) turn on relay
    2) do the job
    3) turn off relay -> no AC power is applied
    4) the large 2000 uF capacity voltage goes down slowly, i.e below 4V
    5) the brown out logic kicks in -> resets the PIC which restarts from begining
    6) goto 1) --> AC power is applied again...

    will try the END statement as suggested above, otherwise will look at the LM2914 power regulator described in an other post.

    Thanks
    Eric

    Hi,

    Describe the electrical circuit used to turn on the device.
    (Push button)?
