Grounding Grounding Cycle Detection Spool Sensors The spool sensors are magnetic reed switches and must be connected to an electrical control. An LED on the switch illuminates to indicate the shifting of the spool. This product must be grounded. In the event of an elec- trical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric cur- rent. -
