The motor control circuit needs some motion feedback from the bell to determine that it is swinging properly. We offer two types of feedback devices to accomplish this. The wiring requirements are the same for both, four conductors of a telco or CAT5 cable usually suffice. | The motor control circuit needs some motion feedback from the bell to determine that it is swinging properly.

A three wire (60 inch cable) proximity sensor provides output when a bolt head or metal flag is about 1/4 inch away. Typically, a bolt is mounted to protrude from the bell wheel or head stock assembly. A stainless steel sheet metal flag is also supplied that can be mounted with dual adhesive foam tape or epoxy to the wheel or head stock. | A three wire (60 inch cable) proximity sensor provides output when a bolt head or metal flag is about 1/4 inch away.

The proximity sensor must be located at least 8 inches from the induction motor brick to prevent electromagnetic interference. It should also be far enough from the head stock pivot to sense small movements of the bell (5 degrees minimum). When the bell is at rest, the bolt or flag should be centered on the sensor. | The proximity sensor must be located at least 8 inches from the induction motor brick to prevent electromagnetic interference.

If you use a cable with other colors to extend these wires, make note of the colors you splice together, so the connections to the control computer circuit board are correct. | If you use a cable with other colors to extend these wires, make note of the colors you splice together, so the connections to the control computer circuit board are correct. | ||
