The “Static Grounding Monitoring System” functions as a part of Overfill Protection & Earthing System. The Static Grounding Monitoring Systems provide a visual green light indicating a confirmed grounding condition of the vehicles during the transfer of flammable and combustible materials. A red light indicates the absence of a dependable ground. An interlock circuit within the Static Grounding Monitoring Systems will prevent pumps and equipment from starting until a satisfactory ground is established. The interlock circuit will also shut off pumps and equipment if the ground is lost during the pumping operation.
