3. 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 will affect temperature compen-
sation. Coil excess cable and protect it so it will not be mechanically
damaged or be sitting in water.
2. Provide a drip loop in all cables so that water or other liquids will not run
directly down the cables onto either
the load cells or the junction box.
Attach load cell cable to the dead
structure, not the vessel.
3. 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.
4. Connect cables for the load cells to the summing board in the junction box
according to the load cell calibration certificate provided with the load cell
and the labels on the terminal strips of the junction box.
5. 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 feet.
