    keyword=Left Mag Q1 Alarm

    Alarm handler is alarming every 30-60 seconds showing a
    problem with Left Mag Q1. It beeps two or three times, and
    then stops. Apparently this started last night.

    John Lerose reports that this happens occassionally because Q1 does not
    have a feedback system installed. At some momentum settings, the setpoint
    current differs from the readback current just within the tolerance. So slight
    fluctuations in current can cause a brief (but frequent) alarm.

    Dave Gaskell recommended against a strategy of slight tweeks in the setpoint to
    better match the readback. So the alarms will continue. Presumably a
    "real" problem will alarm for a longer period of time.
