Junction Box Mounting
JUNCTION BO X MOU NTIN G
The junction box is water resistant, not water-proof. It should be mounted to avoid submersion during wet
weather and to avoid physical abuse. The junction box can be mounted on the front or rear of the drill,
planter or seeder. All load cell cables must reach the J-Box. Install by removing the double sided tape
backing and apply to cleaned surface on the front main hopper support.
Connect Load Cell and J-Box Cable
1. Route front and rear load cell cables to J-box location.
Make sure they are not bound or pinched. Cable tie
(customer provided) load cell cables in place.
2. Insert load cell and J-box cables through each of the
water-tight strain-reliefs.
3. Remove each terminal block from the J-box.
4. Connect wires of the same color to the same terminal
block. See instructions below.
5. Install terminal block into the J-box as shown (location
not important).
6. Tighten nuts on the water-tig ht strain-relie f s.
7. Assure that gasket is properly installed in the cover.
8. Attach cover using 4 screws (provided).
Installing wires into Terminal Block
1. Open levers 90º to locked position.
2. Insert individual wires into terminal.
3. Close lever.
4. Tug wire to assure solid connection.
Note: Wire strip length is 7/16” (11mm).

Trouble Shooting
TROUBLE SHOOTING
How to Check the Drill Scale after Installation
For the first test, lift the drill, planter or seeder all the way up, to a level area. Put 200-250 pounds of weight on
the right side, then compare it to the left. Both sides should be within four to six pounds of each other.
•
If the weight is not within the four to six pound range, inspect the scale system for loose or misalign
mounts.
The second test is to lift the drill, planter or seeder to a level area and zero the scale. Lift t he
drill/planter/seeder up and down two to three times, checking to see if the scale zeros out. Each time the scale
is in the up position, it should be within four to six pounds.
If further assistance is necessary, please call Digi-Star, LLC at 920-563-9700.
***The example we are using is 2000 lbs of seed evenly filled in both hoppers. There is 25 lbs of seed l eft from
the last fill.
Push the “Start” button. The screen will show zero, and the arrow is now pointing to “Net” on the screen. This
is a temporary zero point to start loading the planter with seed. You will now fill 1000 lbs of seed into the left
hopper.
Push the “Stop” button, the readout now reads 1025 lbs of seed inventory.
Push the “Start” button again. The screen will say zero again. Load another 1000 lbs of s eed into the right
side.
Now push “Stop” and the screen will read 2025 lbs of seed. The numbers will work lower as the seed is
planted.
