Before installing and commissioning the Aura 70, read the safety instructions, provisions and conditions carefully.
This paragraph contains a number of general safety instructions. The installation of the device and remedying of
any malfunctions should be performed by a certified electrical installer according to the applicable norms. The
guarantee does not apply if this product is installed in any other way than is indicated by Fancom and if the
product's motor has been opened and changes have been made to the product.
Disconnect power before installation or before carrying out any maintenance to the control computer.
You must be able to switch off the device using a bipolar main switch.
Take precautions against electrostatic discharge (ESD) when working on the control computer. Ensure
the workplace is clean and dry.
Use the wiring/cables indicated on the connection diagrams and follow all. Only apply power after the
wiring has been connected correctly. Incorrect connections can cause permanent damage. Before a
new fuse is placed, the cause of the defect should be remedied by an authorized installer. Only replace
a defective fuse by a fuse of the same type (see connection diagram).
Inspect the control computer regularly for any damage. Report any damage to your installer
immediately. A damaged control computer is dangerous! Do not use running water (high pressure
cleaners) to clean your control computer. The control computer is water resistant, but not waterproof!
Do not switch off the computer when houses are unoccupied; otherwise there is the risk of
condensation in the computer.
The installation, of which this product is a part, must be equipped with a reliable, independent alarm
system, for example, a minimum/maximum thermostat. We advise you to test the alarm system every
day for proper functioning.
Connect each Fancom device according to the applicable legislation/regulations of the local energy
provider.
Check that the mains voltage and frequency, for which this computer is suitable, correspond to the
mains voltage and frequency on site.
Low-voltage and high-voltage wires may not be placed parallel to each other but may cross each other.
When using metal ducts, Fancom advises grounding the ducts at the ends and at as many other places
as possible.
Connect the computers to one group, from the main distributor.
Keep signal and power cables as short as possible.

The Aura 70 is a feed computer especially made for Fancom's EasyFeed feeding system. EasyFeed is a simple
dry feed system based on volume dosing at house level. All the animals are given the same type of feed, no feed
weighing takes place. The EasyFeed system is very flexible and offers the following possibilities:
1. Individual feeding of i.e. sows using dispensers.
2. 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:
Opening the dispensers: when the filling process starts, the dispensers will open and the feed will fall into
the troughs.
Filling the dispensers: when the filling process starts, the dispensers will be filled first.
The basic components of the feeding system usually include a silo auger and a feed chain drive unit. The
System full sensor on the end of the circuit registers if the system is full and stops filling it. A delay time for the
System full sensor can be set to ensure a successful start of the next feeding cycle, there will be still some feed
before the sensor. The silo augers remains off during this delay time to prevent the system from becoming
overfilled (till the silo switch sensor is free). The Return feed sensor turns on/off the feed intake from the silo
auger. If the Silo switch sensor detects no feed it will turn over to the second silo.

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. After a settable wait time the silo auger starts to filling
the circuit until the feed return sensor detects feed. During the settable wait time sections can be inspected and
dispensers can be adjusted per animal. After the wait time the dispensers will open and the feed will fall into the
troughs (Dispenser run time).

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. After the wait time the system starts the circuit filling process. The chain will start first to dose the feed
into the dispensers. After a settable wait time the silo auger starts to filling the circuit until the feed return sensor
detects feed.

Use of the terminal resistor depends on the location of the control computer in FNet. Control computers or end
stations at the beginning of the network require a terminal resistor. Depending on the device type a 120 Ohm
resistance, a jumper or a dipswitch is used to terminate the control computer.
Example: Setting the terminal resistor FNet
Four control computers connected using FNet.
Control computers 1 and 4 are at the end of the network. These control computers must be terminated.
Control computers 2 and 3 are looped. These looped control computers do not require a terminal
resistor.
