Troubleshooting

9.1

Review mechanical installation procedures and perform a thorough visual inspection to be sure

the operating error is caused by a mechanical problem. Then review and check the common

problems listed below.

Note

If you have difficulty determining the cause of the problem, contact your Siemens

representative. Be sure to have the Model Number and Serial Number of your system and all

of the calibration and setup parameters available before calling.

9.1.1

Check for the following conditions:

● weigh deck alignment

Verify weigh deck alignment is as accurate as possible. Improper alignment is the most

common mechanical problem affecting scale accuracy. Contact your Siemens

representative if you find a problem here.

Note

Alignment should be +1/32" (+0.8 mm) to 0" (0 mm) aligned with approach and retreat slider

bars.

● material buildup on weigh section or pulleys, or between the weigh deck and weighfeeder

frame

● belt mis-tracking

● belt too tight

● load cell bolts loose

● speed sensor, pulley, or idler slippage

● load cell shipping bolt (tagged) never removed

● head or tail pulley too high or low, relative to idler/slider bar alignment. The head and tail

pulleys should be at least 1/8" lower than the approach and retreat slider bars
