Fault: "Manual Fill?" "Y [Enter] N [Stop]." What should I do?

Possible Causes:

When the start button is pushed, the computer tells the appropriate valve to open and allow flow from the cubitainer into the vessel. If the liquid is manually poured into the vessel before the computer communicates with the appropriate valve, this fault screen will appear. 

Open the vessel; if the vessel is full, press Y<ENTER> to continue the run. If the vessel is not full, the level sensor may not be functioning properly. Refer to Service Procedure Level Sensor (SICK) Cleaning and Testing (AS010) to service the SICK Level Sensor (blue model). Or see Service Procedure Level Sensor (Analog) Cleaning and Testing (DES007) to service the black model.
