MOVEMENTS:
Rate:
It is the max supposed operating rate of the line and determines the relevant
speed of the transport system making sure just one item is on the scale.
Entry belt speed:
If the machine is equipped with the first little belt for separating
items, its speed can be separately adjusted thanks to this parameter; in this case,
speed is in percentage with respect to the max allowed speed for motors.
Ejector 1 position:
This parameter adjusts the position of the product where the
first ejector shall be activated. The value is in millimetres starting from the reading
position of the photoelectric cell. If this value is 0, the value set in configuration is
valid.
Ejector 2 position:
This parameter adjusts the position of the product where the
second ejector shall be activated (if applicable). The value is in millimetres starting
from the reading position of the photoelectric cell. If this value is 0, the value set in
configuration is valid.
Piece length:
It is the length of the piece in mm. This value avoids double
readings when the item passes by the photoelectric cell and, at the same time,
drives the dynamic weighing algorithm.
To get a proper dynamic weighing, it is basic to set correctly this parameter.
Nevertheless, not always the actual length of the product is the best value; if the
weighing is poor after previously setting the real value, try setting greater and
greater values starting from the mid of the length of the weighing belt.
Selector:
This parameter is used in the
Weight Bounding mode (see par. 2.21)
and for the ejecting function of accepted products 2.18).
