Laying Cables and Connecting Wires
It is the sole responsibility of the installation technician to install and protect wiring
connections per the environmental conditions and in accordance with international codes
of electrical wiring.
After the power supply is installed, lay cables and connect wires as detailed in this
chapter.
Cables
Four groups of cables, described below, are connected to the Afimilk MPC . Cables are
wired to the control box's main cable inside the connection box.
Cable From Description
Communication

A single communication line runs between the
afimilk PC and the parlor. This line "collects" all
Afimilk MPC s (communication from each point
connected parallel to all other devices).
Power
cable
Transformer
Power cable braid wired to each side/batch of milk
meters (according to the size of cable and power
consumption).
Afimilk MPC
body cables
MM body
2-wire valve solenoid cable, 2 wire temp. sensor (2 x
0.75 mm²/21 AWG) and 3-wire electrode cable (3 x
0.75 mm²/21 AWG) run from the body to the
connection box per parlor options.
Apparatuses
Each
Apparatus
2 or 3 wire solenoid cables (21 AWG/0.75 mm²)
connect each wired apparatus (Shut off valve,
pulsator…) to a control box output.
Cable Protection
Run cables inside cabinets if available, or inside cable troughs for protection. Ensure
shortest run as possible, refrain from running cables outdoors and make necessary efforts
to protect communication and power cables from lightning strikes. General restrictions to
consider:
o
Cables must be out of reach of cows & protected from mechanical damage!
o
Communication cable runs should be at least 50cm away from high power lines.
