4.7 Silo
This section is relevant only to houses with feed silo.
The production controller registers feed consumption from the silos by means of feed weighing.
When feed is delivered, the production controller updates the
quantity of feed in the silos based on the information you enter.
For electronic silo weighing, registration is carried out automati-
cally.
In connection with electronic silo weighing:
Inaccuracies can occur when the feed system is in operation and feed is being supplied simultaneously to
a silo that feed is being taken from. This should therefore be avoided.
If feed is still supplied to the silo while the feeding system is running, the controller will stop the feeding
during delivery when using pan, dry and destination feeding. When using tier and chain feeding, the con-
troller uses the experience from normal feedings to calculate the correct delivery amount as well as the
feed consumption.

Silo 1 content
The current amount of feed in the silo. he current amount is continously updated
based on the current consumption.
The menu can be used to correct the current amount of feed. This is used if there
is discrepancy between the actual silo content and the displayed content.
However, the current feed content can only be adjusted if silo weighing is not
used.
When feed is delivered, the menu Silo delivery found under each silo must be
used.
Thus the individual silo deliveries can be found in the silo delivery log.
Automatic change
Setting whether the production controller is to change automatically to a different
silo with the same type of feed when the active silo is empty.
This function is not available when two independent silo weighers are used.
Gradual changeover
For automatic change, the production controller is capable of gradually changing
to a different silo. Setting the quantity of residual feed at which the gradual transi-
tion is to start.
Time before changeover
Setting the time before the automatic change of silos occurs.
Minimum silo content be-
fore change
The production controller considers a silo to be empty when the quantity of feed is
lower than the setting and the silo auger does not deliver feed to the weigher. This
compensates for inaccuracies in the delivery data entered and at the feed
weigher.
If a silo is emptied and the quantity of feed in the silo overview is higher than the
Minimum silo content
, the production controller cannot change automatically. The
quantity must therefore be changed to 0.000 ton for it to be able to change.
