Installing New Triple Beam Load Cell
1.
Slide the new load cell into position.
2.
Install the two front load cell mount bolts. Tighten them by hand.
3.
Start with the bottom load cell mounting bolts and tighten them to 200 in-lb torque.
Now tighten the two front load cell mounting bolts to 200 in-lb torque.
4.
Route the load cell cable to the junction box and connect the load cell accordingto
the supplied interwiring diagram. Repeat for other load cells if necessary.
5.
Perform a load cell balancing procedure as described in the integrator instruction
manual.
Calibration
1.
Power up the integrator and using the appropriate integrator menu, verify that the
new load cell(s) are operating correctly.
2.
Zero calibrate the unit using the integrator manual for reference. Record zero
calibration procedure results.
3.
Span calibrate the unit using the integrator manual for reference. Record span
calibration procedure results.
4.
Run another zero calibration and record the results. Verify that the repeated zero
shows the same value as recorded in step 2.
5.
Confirm calibration with material test as described in the integrator manual, if
possible, before placing the feeder back in operation.
Weighing Idler Alignment
Precise idler alignment is very important to achieve maximum accuracy of the weighing
system. Misaligned idlers will result in unwanted forces being applied on each idler in the
weighing area, causing calibration and measurement errors. Verify that the weighing
idler is aligned properly. Use a spirit level to level the load cells.

SITRANS WW300 - OPERATING INSTRUCTIONS
Run string to ensure idler alignment on both
sides to ±1/32" (0.8 mm).
Use spirit level to level load
cell, on each side.
Secure bolts with idlers aligned and
load cells level. Align both sides and
secure load cells in unison.
