The product
- The system automatically and continuously monitor overfill sensors and grounding status during the loading operation;
- Light indication and alarms provide visual and audible monitor for the overfill status during loading operation;
- It will send status signal to loading controller or other automation system, loading shut down immediately shut down whenever overfill or grounding is monitored;
- Alarm will remind the operator to put clamp back to the seat after loading is finished to make assurance for the safety;
- Optional permissive and non permissive bypass conditions by the button on the truck plug.
