Scale Wiring:
Color codes vary depending on the scale type and load cells used. All four
codes can be tried without damaging the scale or the instrument.
All Eagle Microsystems scales with orange and blue wires use code A.
Code A works with the LP4300, LP4320, WP1000, WT3600, C3600 &
7200, EDS400, most scales with four mounting feet, and our hydraulic
conversion kits with the round load cell (HC3600 & 7200).
Code D or B works with the ECS150x/400 series scales. Try these codes
with any scale with a hinge and a single load cell mounted on top of the
deck. Note: If an ECS has a color code printed on the cable use it but
swap the +S and –S colors!
Code C works with the LP4310, scales with a hinge and cell mounted
inside of the deck, and our HC1000 hydraulic conversion kit.
If your scale or load cell was not obtained from Eagle Microsystems, try
code C or A first. You may want to contact the manufacturer for the color
code. You can also call us with the make and model of the scale and we
may be able to find it for you.
Wiring color codes:
If the wiring code you tried didn’t work:
If code A or B gives you an “A-OL” use C or D and vice-versa.
If the instrument shows a weight but the gross reading goes down when
weight is applied, swap the wires on the + and - S terminals.
If the instrument reading is unstable, check for loose connections.
