A stable weighing signal is important to achieve a correctly registered feed consumption, feed supply and silo
weight.
Therefore, the following conditions must be considered when installing
• Signal cables from the load cells to the load amplifier must be as short as possible. However, all cables
must have the same length.
• The signal cable from the junction box to the load amplifier must be as short as possible.
• Shielding must be connected at all load cells, in junction box and in load amplifier.
• There must be a least 1 meter from the signal cables to the supply / power cables.
• CAN bus cables from the load amplifier to the controller must be as short as possible, and shielding must be
connected.
• There must be a least 1 meter from the CAN bus cable to the supply / power cables.
• All load cells must be connected to the same ground.
• The silo must “float” in the mechanical mounting.
• The silo must not slope more than 1 %.
3.5.4.5.5 Feed weigher
Tip weigher
Setting the tip weigher to the required number of kg per kip.
Provides an impulse for each portion of feed weighed.
Feed per second
Setting the time-controlled feed weigher to the required number of kg per second.
Fill amount weigher
Setting the max. quantity of feed per weighing (drum weigher and DOL 9940).
Factory-set values: 20 kg
Remember to change this to 40 kg if DOL 9940 is used.
Feed regulation
Max. run time cross
auger
Setting the max. time for auger run without the weigher delivering feed. Then the
production controller stops the auger. It will not restart until the weigher delivers
food again or the feed demand sensor is influenced.
Feeding according to
light program
Feeding is regulated according to the time settings in the light program. With chain
feeding, the first half begins at "dawn".
3.5.4.5.6 Silo
Silo 1 capacity
Setting the maximum capacity of the silo. Used in connection with graphical view on
silo cards and in the management program FarmOnline Explorer
Name
This is used to name a silo according to function, so that it can be recognised in the
menus and alarms.
3.5.5 Water
Liters pr. pulse
Setting the number of liters that runs through the water meter for every pulse.
Water meter relay set-
tings
By selecting a relay for a water meter, it is possible to shut off the water in the
event of excessive water consumption.
The relay cannot be activated in the event of power failure. In this case the water
will be switched on.
