Updated over a week ago

No LED – No flow cell connected

Solid blue – Flow cell ready

Solid green – Script running

Solid white – Script completed

Solid red – Error

Please note that upon connecting a flow cell to the sequencer an initialization script will commence, which will change the LED from blue to green and then to white upon completion, without user intervention.
