Especially when the fill material has pieces, it may happen that the first pieces
that fall in the container after coarse flow has started will generate peak loads
that will already cause the coarse flow cut-off point to be exceeded. You can
prevent that with this setting. Experience shows that the lockout time should be
about 10 % of the coarse flow dosing time. If you are using the coarse flow cut-
off point monitor, the lockout time must be sufficient for material to enter the
container.

10.2.29 Fine flow monitoring (time interval) (
Fine mon.(s)
)
This command is used for breakage monitoring during the fine flow phase
(sack breakage). Enter the increase in weight you expect per time interval in a
normal filling process. At the end of the fine flow lockout time, the increase is
then checked after each time interval. If the weight increase rate is not
exceeded this fact is interpreted as a breakage of the container being filled,
and dosing is aborted. Fine flow fill flow monitoring is deactivated when the fine
flow cut-off point is reached.
If you enter the target weight the monitor is automatically deactivated.
