Routing cables

Caution!
Cable damage is the most common reason for load cell failure. To avoid damage, secure and protect the
cables. Good practice is to feed cables through plastic piping or a conduit.
The junction box is the central point where all five cables are routed.

Connecting wires

5
The matching coloured wires in the load cell and the indicator cables are connected inside the junction box.
Note:
The orange wire is not used.
Sealing the junction box
6
After connecting the wires, you must ensure that the junction box is watertight:
Neatly fit the wires and terminal blocks inside the junction box.
1
Tighten the five cable glands.
2
Replace the junction box lid and tighten the lid screws firmly to ensure a watertight seal.

Testing the system

7
After installation, the load cells should be tested.
Connect the load cells to a Tru-Test indicator.
1
The Tru-Test indicator should automatically identify and calibrate to the load cells, then show it is ready for weighing
with "0.0" on the display. If this does not happen you may need to update the software in your Tru-Test indicator. For
other brands of indicator, contact their local representative as you may need to calibrate.
Turn on and zero the indicator.
2
Attach the load cell cables to the chute/crush using cable ties or other
1
means.
Push the four load cell cables through the cable glands at the bottom of
2
the junction box (in any order).
Mount the weigh scale indicator and route the indicator cable.
3
Four terminal blocks with levers are provided.
Before inserting the wires, ensure that you fully open the levers to a 90-degree
1
upright position.
Insert the four load cell wires and the indicator wire of the same colour (e.g. red-
2
red) in each of the terminal blocks.
Secure by pushing down the levers.
