9.2.29 Lockout time coarse flow

Once coarse flow is activated, comparison of the actual weight for reaching the
coarse flow cut-off point is disabled for the specified duration. The time does
not delay the filling process.
Especially when the fill material is made up of pieces, it may happen that the
first pieces that fall into 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.

9.2.30 Fine flow monitoring (time interval)

This command is used for breakage monitoring during the fine flow phase
(sack breakage). Enter the increase in weight you expect per time interval
during 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.
