Load Cell Connections With Over 30 Feet Of Cable; Sense And Dead Load Jumpers - Cardinal 190 Installation, Technical And Operation Manual

8. To terminate a wire, loosen the screws in the terminal block and then insert the wire into the
terminal opening. Tighten the screw to secure the wire in place. See Figure No. 4.
9. Repeat the procedure until all wires are in place.
10. After all terminations have been made, remove the excess cable from the enclosure.

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.

Sense and Dead 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).
