None.

act dvpump on|off
The piping from the drum includes a valve so that we don't always draw vacuum on
the drum. This valve will normally let air from the atmosphere be drawn into the
vacuum, during loading the valve will be redirected to evacuate the inside of the
drum to hold a plate on. The pump will then draw vacuum on the drum until after
the plate is unloaded.
The valve is controlled via the "act dvflow" command
BETA SPECIAL: Until the Beta machines are retrofitted (until this message disappears)
they are different!! The Beta machines have larger drum vacuum pumps that are turned
off after an unload and don't use any valving. The beta machines do not have a
dvflow command, only a dvpump command.
