The G2 Series provides a positive ground indication through the use of an intrinsically safe monitoring circuit driving a switching relay. Upon connection of the self-releasing clamp and cable to a conducting material, the intrinsically safe circuit is completed and the operator will be shown a green light to indicate that a ground connection has been established.
While most competing systems only monitor the path from the ground unit to the clamp, the G2 Series also employs a segregated cable connection to the actual ground, which is also monitored for low resistance. An interruption in either path (indicated by any resistance above 5 ohms) will shut down the system.
The system can also be interlocked with filling equipment to ensure that no flammable product can be transferred until the ground is established. If the circuit is broken by the release of the grounding clamp or other ground interruption, the control relay will open and a red light will be displayed. Any filling equipment that is controlLED by the system will also be halted until the ground is re-established.
The G2 Series systems will do the following: shut down a pump or valve; sound an alarm; show a red light when conditions are unsafe; show a green light when conditions are safe; open contacts on a computer; indicate that static path to the ground has integrity and receive permissive signals from computer control.
