2.
Turn on the feeder and observe its tracking line on the head and tail pulleys.
If the belt is drifting toward one side of the feeder, then adjust the telescoper on
either side of the machine (see below).
3.
Do not adjust belt tracking rollers, they have been factory set.
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 adjustment (1
turn or less) is required.
4.
Observe the results of the adjustment and then readjust, if necessary.
As you extend or compress the telescoper, you may be changing the belt
Note:
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 build-up on head or tail pulleys.
