3.0 Load Cell Wiring
1. Route the load cell cables so they will not be damaged or cut. Cable should not
be routed near heat sources greater than 150

F (66

C).
Do not shorten any load cell cable.
* The load cell is temperature compensated with the supplied length of cable.
* Cutting the cable affects temperature compensation.
* Coil excess cable and protect it so it does not be mechanically damaged or
sitting in water.
* Cutting the coil voids the warranty.
Figure 3-1. Drip Loop
2. Provide a dip loop in all cables so water or other liquids will not run directly down
the cables onto the load cells or the junction box.
3. Attach load cell cable to the dead structure, not the vessel.
4. If conduit protection is necessary against mechanical or rodent damage to the
load cell cables, use flexible conduit and conduit adapters at the load cells.
5. Connect cables for the load cells to the summing board in the junction box
according to the junction box manual. To verify the wiring scheme, see the
certification shipped with each load cell.
6. For better performance, use positive and negative remote sense lines if the
wiring run from the junction box to the indicator is longer than 25'.
3.1 Junction Box Connection
Refer to the junction box manual for connections, adjustments and calibration. It also
contains the trimming details.
Refer to indicator manual for system calibration guidelines.
