Wide-Belt Sander Shutting Down
I checked to see if the belt was hitting the triggers (not sure of the exact name) on either side that automatically shut the machine down but thatís not the issue. Plus Iíve widened those both another 1/4" outwards to make sure the belt wasnít hitting the triggers. Iím wondering if its an electrical current issue or does it have to do with the machine itself since it just started doing this recently. Has anyone had an issue like this and if so how did you resolve it?
From contributor J:
We had that problem at a job I had. The infrared eye was getting too dusty, so they put a low pressure air line to keep it clean. The guys wood just hit a button every few minutes of operation and it worked great! It stopped screwing up work and destroying belts.
From contributor A:
Contributor J - that is a great tip.
From contributor B:
If you are comfortable doing so, open the electrical panel and check the tightness of all electrical components. It is fairly common for connections to loosen over time. If you have a connection that is loose in the contactor (start/stop) circuitry your problem is exactly what will occur.
Start first with the stop button connections. The stop button opens the contactor circuit subsequently stopping the machine. A loose connection in this circuit will have the same result. Also, if the machine has an emergency stop bar (like mine) look to make sure that isn't rattling into the stop button behind it.

Another possibility; is the incoming voltage within 10% of the voltage the machine is rated for? Less than that and the control circuit could drop out due to not enough control voltage to maintain the control circuit relay.
