This data item specifies the nominal belt speed in meters/second. When there is no speed sensor, the
software assumes the belt is moving at this speed and converts distances to times accordingly. In particular the
Marker Distance
data item is converted into a time delay using this value.

A count of the number of times tramp metal was detected since the metal alarm was raised. This is useful in
setups where the belt is stopped when tramp is detected. A coast count greater than 1 tells the user that
additional tramp came through while the belt was stopping. The additional tramp will be located somewhere
between the marked location and the detector.

A count of the total number of times tramp metal was detected during the life-time of the detector. This value
will not increase beyond 9999.

A boolean flag which specifies that a speed sensor is present. A speed sensor is a crude belt position feedback
device. Each speed sensor pulse corresponds to a certain amount of belt movement. When this flag is set, the
detector will use the speed sensor to determine belt speed and position. This will affect marker activation and
clip detection. Both of these features have distance type parameters
. For instance “marker distance” specifies
the belt distance from the detector to the marking device. If there is no speed sensor, the detector assumes
the belt is moving at the speed specified by the nominal belt velocity and translates this distance parameter
into a time. When the belt is ramping up to speed or stopping this feature does not work correctly. When a
speed sensor is present marker control works correctly even during speed ramps.
