Sense Jumpers (+SEN, -SEN)
If the sense leads are NOT used, you must install plug-in jumpers at +SEN and -SEN adjacent
to the terminal block. These jumpers attach the sense leads to the excitation leads. If sense
leads ARE used (as in motor truck scales), these plug-in jumpers should be positioned on one
plug in pin only or removed and stored for later use.
SCALE 2
To use the sense wires for Scale 2, the +SENS (J5) and -SENS (J6) jumpers on the
225-DS must be open (on one pin only) or removed.
SCALE 3
To use the sense wires for Scale 3, the +SENS (J3) and -SENS (J4) jumpers on the
225-DS must be open (on one pin only) or removed.
Dead Load Boost Jumper (DLB)
For very low dead loads (less than 10% of the combined load cell capacity) connect the dead
load boost (DLB) jumper on the printed circuit board. Refer to Figure No. 12. For Scale 2, the
DLB jumper is J2. For Scale 3, the DLB jumper is J1.
GND to Chassis Jumper
When installed, this jumper connects the analog circuit ground to the indicator chassis ground.
Refer to Figure No. 12. For Scale 2, the GND to Chassis jumper is to the right of P2 (near the
ground wire). For Scale 3, the GND to Chassis jumper is to the left of P3.
