3.4 Load Cell Connections with Over 30 Feet of Cable
For installations with over 30 feet of cable between the indicator and the
load cells, sense wires should be used. The sense wires must be
connected between the +SENS, -SENS terminals on the indicator and the
+EXCITATION, -EXCITATION wires of the load cells or the +SENS, -
SENS terminals of the load cell trim board or the section seal trim board.
3.5 Sense and Deal Load Jumpers
J1 (+SEN) and J2 (-SEN) – Sense Jumpers
If the sense leads are NOT used, you must install the +SEN and -SEN
jumpers at J1 and J2 (near the P5 terminal block). These jumpers
connect the sense leads to the excitation leads. If sense leads ARE used
(as in motor truck scales or installations with over 30 feet between the
indicator and load cells), these jumpers should be open (on one pin only)
or removed.
J3 (DEAD LOAD) – Dead Load Boost Jumper
For scales with very low dead loads (less than 10% of the combined load
cell capacity), connect the DEAD LOAD (dead load boost) jumper J3 (near
the P5 terminal block).
