Pneumatic or electric proximity detection sensors, combined with existing mechanical safety interlock features ensure the safe function of the ChargePoint® and integrated lifting equipment in fully automated, inaccessible or hazardous area operations. The detection signal can be used in conjunction with a ChargePoint® or customer supplied control system providing an identification sequence which typically involves:
- Positive identification Passive unit is correctly docked into Active.
- This provides release mechanism to lock the Passive to the Active unit.
- Further detection confirms this locking is complete.
- This allows the valve disc to be opened.
- Additional detection confirms the valve is open.
