Connecting to a Plug-in Connection Box
NOTE
No more than 64 milking points may be connected to the same AfiCom1
port. The communication cable must therefore be cut into lengths with no
more than 64 extension tails each. Where there are more than 64 milking
points, use more than one length of communication cable.
1. Install an AfiPort to the desired port of AfiCom1.
2. Connect the communication cable as in Figure 24.
NOTE
The last PICB in the line must have a Communication Line Termination
(P/N 9030544). This connects between socket number 10 and the RS485
line. It reduces noise.

Installing a Shut-off Valve Using the Valve
installation kit for AfiFree
CAUTION
A valve installed at an angle from the vertical cannot drain completely.
 Water in the valve at the end of the washing cycle can be a source of
bacteria
 In sub-zero temperatures the water might freeze.
AfiMilk recommends that the shut-off valve be installed vertically.
Where vertical installation is not possible because of a physical limitation (such as a
low milking platform) the shut-off valve can be installed at an angle of up to 90° from
the vertical.
