Magnetic Position Feedback
Rotary Positioner:
The magnetic beacon should be set in the proper orientation, based on the direction of failure.
Linear Positioner:
The magnetic assembly supplied with the positioner should correspond to the stroke length and
failure direction of the actuator. To make sure that the appropriate magnet assembly was selected, check the part
characteristics. The stroke length and failure direction should be printed on the part. On the older ICoT the magnet
assembly is not printed with this information, although a serial number should be visible. Contact Westlock support
with the serial number in case of doubt.
