Chapter 3: Basic connections
Connecting the Power Supply
You have to connect a power supply to the Bin Scale Module . There are two possible configurations, con-
necting to the EDGE Controller power supply network or to an independent power supply.
What You Should Know
The following table will guide you on how to correctly wire the Bin Scale Module to respect the power rat-
ings of the different supply.
IMPORTANT: Do not exceed the power supply rating.
Power consumption of Bin Scale Modules
3 Wires LC 3W
4 Wires LC 3W
Available power
EDGE 6 slot expansion box 5W
EDGE 3 slot expansion box 25W
External power supply (PSU 24V 20W) 20W
For redundant power supply topology, use the available power of the bigger expansion box.
NOTICE
When tightening small terminal blocks, use a torque between 4.43lbf*in (0.5N*m) and
5.2lbf*in (0.6 N*m) to fasten a wire gauge from 16AWG (diameter of 1.29mm or cross
sectional area of 1.30mm
2 ) to 18AWG (diameter of 1.02mm or cross sectional area of
0.82mm 2 ).
The recommended installation wire gauge is 16 AWG (diameter of 1.29mm or cross sectional area of
1.30mm
2
) when using power supply wires at a length of 1000 feet (300 meters). Consult the wiring dia-
grams to see the maximum cable distance according to the wire gauge.
WARNING
Installation must only be performed by qualified service personnel.
To connect to a DC network:
1. Locate the terminals (Automation or Safety on the EDGE Bin Scale you want to connect.
2. Connect the wires (24V and GND) from the EDGE Bin Scale to the network.
IMPORTANT: Make sure to connect same signal identification together and use the same network
from one side to the other.
IMPORTANT: If redundancy supplies are not used, use the Automation bus.
IMPORTANT: Consult the EDGE Controller user manual to have information about the redundancy
supply concept.
To connect an independent power supply (PSU 24V 20W):
IMPORTANT: Install a disconnect switch to interrupt power to L1 and N/L2 electric power lines
before connecting the system’s main input on the power supply. It must be in close
proximity to the equipment and within easy reach of the operator. It must be marked
as the disconnecting device for the equipment.
