9. After the cycle time elapses, the cycle ends and the canisters index counterclockwise again to the

next station.  The dried material that was in the Vacuum Station has now moved to the
Dispense Station. Two cycles have passed and the dried material is ready for production.

From now on, indexing occurs at the end of each cycle time.  This is the standard mode,
"advance on time".  if you have selected the "advance when empty" option, then indexing occurs
only when the level sensor below the Dispense Station indicates the dispensing canister is
empty.

If you are using "advance when empty" option you have the ability to set a short fill time. If the time to use
the material in the canister is more then double the minimum cycle time set on the cycle time thumbwheel,
we suggest you decrease the Fill time so that the canister does not hold so much material. Excessively long
cycle times may allow dried material to begin to re-absorb moisture.
