Lumina 41/42 The Lumina 41/42 feed installation
3
The Lumina 41/42 is especially developed to control a feed installation. The feed is transported to the house in
weighed batches (portions).
Depending on the software version feed can be mixed and can be distributed to 1 or 2 houses.
Parts of the feed installation
A typical feed installation controlled by the Lumina 41/42 consists of the following parts:

1, 2, 3 or 4 silos.

Dosing out auger(s) of feed to the hoppers.

Weigher with weigher hopper.

Dosing out auger of feed to the storage hoppers. An additional auger to divide the feed over two houses
(option).

Feed lines with augers to transport the feed from the hoppers to the feed pans.

Sensors, controllers and auger drive mechanism.
The afterflow is the amount of feed that still flows after the auger has been stopped.
With automatic dosing in based on weight the control computer takes an afterflow into account. The dosing in
auger will stop before the weigher registers the required weight.
The afterflow does not need to be set: the control computer calculates this automatically and adjusts this value
during the feed process. The afterflow will not be adjusted if the actual afterflow is higher than the max. dosing in
difference of the ingredient.
The dosing capacity of the silo must be set in the control computer. This setting is used in the following situations:

Determination of the maximum dosing time if the minimum amount decrease in 30 sec has not been set. The
maximum dosing time is five times the necessary calculated time. If Capacity Kg/minute has not been set
either, the control computer will use a maximum dosing time of 60 minutes.

Dosing in feed ingredients based on TIME. If the amount to be dosed is less than the afterflow, dosing in is
time based.
The control computer will give a signal if the feed amount in the weigher does not decrease sufficiently within 30
seconds. If not enough is dosed in of a feed ingredient, the control computer will try to re-start the entire dosing
process several times.
If an ingredient cannot be fully dosed from a silo, the control computer will try to switch to another silo storing the
same ingredient. If this is not possible, the control computer can use a replacement ingredient. The control
computer will give a message. If finding a replacement ingredient also fails, the control computer will stop the feed
process and give a loud alarm.
