7.6 Telescoper adjustment

7.6

Telescoper adjustment

1. Determine which side of the weighfeeder you want to adjust. Compressing the telescoper on

one side will cause the belt to drift toward that side of the weighfeeder. Conversely, extending

the telescoper will cause the belt to drift away from that side of the weighfeeder.

2. Loosen the jam nut.

3. Turn the adjusting screw in the desired direction. Often, only a small amount of adjustment (1

turn or less) will be required.

4. Observe the results of the adjustment and then readjust, if necessary.

Steps 2 and 3 may need to be repeated to obtain perfect belt tracking.

Note

As you extend or compress the telescoper, you may be changing the belt tension. If belt

tension has increased (or decreased) considerably while attempting to track the belt, then

compress (or extend) both telescopers and complete the belt tracking process again. To

avoid this problem, extend one telescoper while compressing the other to obtain proper

belt tracking.

5. Re-tighten the jam nut located on the telescoper to maintain the new telescoper position after

completing the tracking procedure.

6. If you are having problems tracking the belt, consult your Siemens representative. Common

causes of belt tracking problems are: uneven or improperly distributed product loading,

twisted frame, or product buildup on head or tail pulleys.
