System - 11.2 - Manual controls

You can directly control the separate firefly modules using the Manual Controls. You may need to do this to reset firefly after stopping a protocol: specific instructions for resetting are shown for the firefly modules you would need to use to do this.


Do not operate firefly using the manual controls unless you have been trained to do so.


A brief overview of these controls is included here for reference.The appearance will be specific to your instrument type e.g. only 3 dispense heads are shown for 3 head instruments, with the other 3 greyed-out. If you access the manual controls during protocol execution e.g. to resolve a problem, they will show the current arrangement of labware.
