Chapter 4: Operation 41 of 60
Alarm Flags
An alarm message will be shown if any alarm condition occurs. A message will pop up on
the screen until the alarm condition is resolved. The operator can press “OK” on this pop-up
to hide the screen temporarily, but if the alarm condition is still unresolved, then the message
will reappear after a short delay. During an alarm condition, a visual alarm will be activated.
The following is a list of all alarm names and descriptions:

The dump valve opens as soon as you touch the “Reload Off” button. The button then
changes to show “Reload On”.
Print Inventory
The print inventory menu item is used to produce on demand, inventory printouts. Before
selecting this item, be sure that the printer is properly connected and ready. This function will
generate an inventory.
Note: The system will stop if you attempt to turn the manual reload on. This
could be devastating if you are running the extruder.
