Expert Reply:

We don't carry the Marshall line but if it's anything like the Camco Automatic Changeover 2-Stage Propane Regulator for Dual Propane Tanks # CAM59005 the regulator should automatically switch over to whichever tank is open and full. The lever is simply to show you how full the tank is using the small green to red indicator.

It wouldn't matter if one tank was closed since it would be the same as if the tank was empty and the regulator had to switch over to the other full tank. The only issue might be when removing the tank from the regulator if there isn't a backflow inlet to prevent gas from escaping through the open line. Typically this is the case either with the regulator or pigtail hose but you'd need to confirm with the manufacturer of the regulator.
