The Scully Groundhog™ gives you complete assurance that grounding to the vehicle's frame has been accomplished*. The Groundhog™ is an intelligent system which continuously and automatically monitors the grounding connection during the entire loading operation. The Groundhog™ is designed to immediately shut down the loading operation if the ground tie-in is broken. That’s proof-positive, something no other system can provide. The Groundhog™ control monitor is mounted at the gantry. Indicator lights on the face of the control monitor are visual proof that proper grounding has been accomplished. The Groundhog™ requires that each vehicle is equipped with a specially designed Scully electronic ground ball or bolt. Before the loading operation can begin, the controller must see an intelligent return signal from the ground ball or bolt, indicating that a proper grounding connection has been made. The Groundhog™ Control Unit can be wired into your existing Scully Overfill Prevention System for the ultimate safety system. Just one connection gives you overfill and grounding protection. This single connection simplifies loading and eliminates the need for additional plugs and cables at the gantry. The Groundhog™ utilizes a spare conductor in the existing Scully Overfill Prevention Plug and Cable together with a special Scully Ground Bolt mounted on each vehicle. The Scully Ground Bolt’s sensing lead is wired to the Scully Overfill Prevention Socket. Only Scully offers you a complete, integrated overfill prevention and vehicle grounding system for maximum safety in your loading operations. ARE YOUR GROUND I NG SYSTEM OPT I ONS L IMI TED?
