3E2374 Sheep Auto Drafter User Manual
Note: If you are wanting to read EIDs then make sure you keep the power supply
1m, or more, away from the unit side panels to avoid interference with the RFID
reader antennae.
Compressed air requirements
Once the compressor is connected and running you will be able to see what the
pressure is at the unit by looking at the pressure gauge attached to the Control
Bridge (see Figure 4). It should read between 4-6bar (in the green zone). Ensure
it does not enter the red zone (>6bar). A reading above 6bar indicates a regulator
issue, which would need investigation. Readings below 4bar are likely to be
caused by an air supply (compressor) problem. A typical compressor would be a
2HP 24 litre tank single phase machine.
Scales and RFID reader requirements
The Sheep Auto Drafter has been specifically designed to operate with the
Gallagher SmartTSi, SmartScale 800, Weigh Scale 810 and Weigh Scale 610
scales. (Please note: Drafting by list is not available on the Weigh Scale 610
scale.) It will also operate with some other brands of weighing indicators - your
dealer will know which are compatible.
RFID (radio frequency identification) antennae are installed in each of the unit
side panels. A SmartReader BR or R unit is needed to communicate with the
antennae.
The antennae will recognise EID which are either HDX (half duplex) or FDX (full
duplex), and those which are inserted as implants or boluses (however these are
less commonly used).
