    Entry number 81606

    keyword=Access to reset HV06

    HV06 (RCS Veto counters and laser trigger) tripped badly. Remote
    reset did not help. We had to get access to the hall (anyway there was no beam).
    The crate had power on, but did not respond to anything. We cycled the power
    to no avail. Then, we removed all the HV modules save one in slot 0.
    The crate became responsive. The internal HV settings appeared to have been lost.
    After plugging all the modules back the crate
    was still working all right. However it is beeping all the time after entering
    the "remote" mode, at a frequency of about 1Hz.
    The manual has no comprehensive explanation for this message.

    Anyway, the crate seems to work. We are not sure the crate
    had not been beeping before - it is the crate we put as replacement about
    a week ago. The signal can be heard at a distance closer than 30-40 cm
    to the crate, because of noise in the hall.
