Status Indicators

The instrument status indicator indicates one of four possible instrument

conditions:

• When the status indicator is OFF, the instrument is in a prerun condition,

and is ready to begin an analysis.

• A green status indicator indicates the instrument is performing an analysis

(run mode).

• A yellow status indicator indicates a not-ready condition. The instrument

is in a not-ready state when it is waiting for a specific condition to be

reached or completed, or while a self-test procedure is running. The next

programmed injection will be inhibited until the not-ready condition has

been cleared.

• An error condition is indicated when the status indicator is red. An error

condition indicates the instrument has detected an internal problem which

affects correct operation of the instrument. Usually, an error condition

requires attention (for example, leak, defective internal components). An

error condition always interrupts the analysis and prevents the next run

after the current run is finished.

• A flashing red status indicator indicates a severe error during the startup

procedure of the module. Call your local service provider for assistance

upon observing this error condition.
