Vapour Recovery Vent Interlock for RCM Permissive

The Issue

Some customers require a vapour recovery vent interlock for loading at a rack. The vapour recovery vent must be open for loading.

The vapour recovery vent must be open before the RCM permits loading.

• The open vapour recovery vent is detected by a switch on the vent control. This can be a mechanical or pneumatically operated switch.
• The vent interlock switch provides power to the RCM when the vent is open. Power is removed from the RCM when the vent is closed.
• The RCM can permit loading only when all conditions are safe for loading including the open vapour recovery vent.
