Panel Indicators and Connectors – Front Panel
55
When the Reference 3000 is first turned on, the
Power
LED glows steadily for a second or two, blink three
times, and then go to its normal steady blue output. Each blink in this sequence indicates successful completion
of a portion of the Power PC’s power-up self-test routine.
A Reference 3000's
Power
LED blinks when that instrument is selected in the Framework’s Instrument
Manager. This allows easy identification of a specific instrument in a MultEchem system without looking at the
instrument Serial Label on the bottom of the instrument chassis.
When the
Power
LED is off, one of the following is true:
The rear-panel power switch is off.
There is no DC +24 V supply connected to the rear panel DC
Power In
connector.
The external DC power supply has no input power or is malfunctioning.
One part of the Power PC’s power-up self-test has failed.
Caution:
The
Power
LED is used both to indicate power status and that power-up tests
have passed. It therefore cannot be relied on as a true power-status indicator. Always unplug the DC
Power In
connection if you suspect your Reference 3000 is malfunctioning.
