- 1.0 Introduction
- 2.0 Installation
- 1. Place scale in final position and carefully remove it from the packing skid.
- 2. Level the corners by shimming under the corner gusset plates.
- 3. Back off all shock-stop bolts that were tightened down for shipping safety and adjust them to 1/16" clearance for weighing.
- 4. Route the load cell cable to the digital weight indicator and connect.
- 5. Drill anchor holes, and bolt or lag the scale to the floor using the tie downs.
- 6. Calibrate with test weights.
- 2.1 Unpacking the Scale
- 2.2 Scale Setup
- 1. Lift the base assembly off the skid with hooks and chains in the same manner as the deck assembly, position it in the desired location.
- 2. Add shims as necessary under corner gusset plates until all corners are firm and the base does not rock.
- 3. Locate these shock-stop bolts (see Figure 2-2), loosen and set the clearances as indicated.
- 4. Lock into position with the lock nuts.
- 5. Remove the plate covering the signal cable access hole.
- 6. Cut the plastic ties holding the load cell cable against the levers.
- 7. Pass the signal cable through the access hole.
- 8. Remove the split rubber grommet from the cover plate and place it around the signal cable.
- 9. Slide the grommet back into the cover plate and install the cover plate back on the base assembly.
- 10. Attach the signal cable to the digital weight indicator in the following manner:
- 11. Ground the scale base to the earth ground terminal of the same AC power source that is used to power the indicator.
- 12. Locate two floor tie down brackets on the inside of the base assembly, located diagonally across from each other just off the centerline. These brackets are raised off the floor a little to handle uneven floors.
- 13. Fill the space with washers until snug.
- 14. Drill pilot holes into the floor through the holes and washers in the tie downs.
- 15. Fasten the tie down brackets to the floor with lag bolts or suitable masonry fasteners.
- 16. Replace the deck assembly carefully using the match marks to ensure corners are not changed.
- 3.0 Calibration
- 1. With the deck in place and no additional weights on the scale, set zero on the digital indicator according to the procedure described in the indicator’s operating manual.
- 2. Place certified test weights on the scale, using 75-100% of the scale capacity.
- 3. Span the meter to actual capacity using the procedure in the operating manual.
- 4. Remove the test weights and re-zero the indicator.
- 5. If required, repeat the above procedure until the unit is correctly calibrated.

- 4.1 Troubleshooting
- 4.2 Load Cell Replacement
- 1. Remove the deck assembly (see section 2.1 on page 2).
- 2. Loosen the lock nut on the shock-stop bolts shown in Figure 4-1 and turn them down against the angle until finger-tight. This locks in the correct lever height for the load cell.
- 3. Remove the signal cable access hole cover plate. Pull the cable from the plate and pass it through the base.
- 4. Remove the lower lock nut from the wire rope and back off the upper lock nut.
- 5. Using a hex allen wrench in the flathead bolt, and an adjustable wrench to hold the load cell body, remove the load cell.
- 6. Keep track of the washer above the load cell.
- 7. Remove the wire rope from the defective load cell and screw it into the new load cell to the approximate position it was in the old load cell.
- 8. Insert the wire rope into the nose iron hole and turn the lower nut on loosely.
- 9. Hold the flat washer in place, and screw the flathead bolt into the top of the load cell. Tighten the flathead bolt securely using the hex allen wrench and adjustable wrench.
- 10. Tighten the lower lock nut on the wire rope against the nose iron finger tight only. Lock the upper nut down against the nose iron.
- 11. Release the load cell shock-stop bolts and set the clearance to 1/16''.
- 12. Lock into place with the lock nuts so the bolts do not loosen and contact the frame during weighing.
- 13. Pass the signal cable through the access hole and follow Steps 6-11 on page 2.
- 14. Replace the deck assembly and recalibrate according to Section 3.
