Feeding of groups of rearers or fatteners using liquid and dry feed troughs is possible. The Aura 70 has a built-in time clock. The feed system is started externally or automatically at preset times. The Aura 70 enables to choose whether you will start: ...
Aura 70 Aura 70 Figure 2: Schematic view for positioning the components When the option ‘Filling the dispensers’ is chosen, the circuit will be filled first (circuit filling). This method is usually used with dry or liquid feed troughs but there are also situations using a combination with dispensers. The chain will start first to dose the feed into the dispensers.

Aura 70 Aura 70 When the option ‘Start with dosator’ is chosen, the dispensers will open and the feed will fall into the troughs (Dispenser run time). During the settable wait time sections can be inspected and dispensers can be adjusted per animal.
Aura 70 Using the Aura 70 This chapter describes the main parts and the operation of the Aura 70. The Aura 70 can be operated on the touch screen. Touch screen Silo 1 control switch Silo 2 control switch Circuit control switch (automatically switch off in case of a chain break) Dosator control switch The computer is automatically activated as soon as you switch on the power.

Aura 70 Using the Aura 70 The Aura 70 screens are divided in three sections: Title bar: Displays the date and time and provides access to the installation and user menu. Working area: Displays the data user or installation settings of the control computer.
Aura 70 User settings Silo Auger: If the silo auger is active the auger will light up green. Silo’s: If more than one silo is used the silo number will appear in the icon. Silo switch over sensor: If a silo is empty (sensor detects no feed) the system switch over to the other silo (only if more than one silo is used).

Aura 70 Alarm Max. runtime circuit Setting of the maximum runtime (hours:minutes). One setting for all circuits. The control computer stores the alarm history. The computer stores the last six alarm messages.
Never mount the Aura 70 in a humid and/or dusty room and certainly not in the room where the animals are present. Mount the Aura 70 at such a height that you can control the Aura 70 easily (eye level) and square on a solid backing. The swivels should be positioned at the bottom.
