Description of ICP-OES 5000 Series Status Indicators (LEDs)
The Agilent 5000 Series ICP-OES (5100/5110/5800/5900) has two different LED indicators to advise the status of the instrument. The state of both these indicators determines if the instrument is in a fault condition or ready to operate condition. The ready to operate condition is shown when both indicators are a steady green color. Any other color (steady or flashing) indicates a fault condition.
- Indicator one. Instrument power On/Off switch, on the bottom-left side of the instrument. The LED combination provides feedback on instrument status as indicated in Table 1.
Table 1. Instrument Power Switch LED states
On/Off Switch green LED
Brief flash once every 10 seconds
Most of the instrument is unpowered. The instrument can be turned on (powered up) by depressing the soft on/off switch at the front. Mains power is active inside the instrument
Flashing slow (1 Hz)
Mains power module is proceeding through the startup check sequence while transitioning between Off and On states
Instrument in On
Flashing fast (2 Hz)
Mains power module failed its power-up self-check, instrument is unusable. Mains power supply is not adequate or the internal mains module requires replacement
2. Indicator two. Instrument status LED indicator, on the top-right side of the instrument. The LED color combination provides feedback on instrument status as indicated in Table 2.
Table 2. Instrument status states
Status LED Color
• Instrument off
• Instrument starting
• Instrument switching off/shutdown
Note 1: Soft on/off switch LED indicates status of any powering up activity during these states
• Instrument Startup
Red Slow Pulse .. .. ..
• Firmware Loading
Yellow flashing (0.5 Hz) .. .. ..
• Host is not connected (regardless of whether plasma is lit or not)
Note 2: This LED status has higher priority than solid Yellow or Green, but lower than Red
• Host is connected but the instrument is not ready to begin a plasma ignition sequence. Possible causes include door or torch handle interlock tripped, low instrument water flow (uses camera flow sensor to detect if water connected and flowing)
• Host is connected, ready to attempt a plasma ignition sequence
• Host is connected, plasma ignition sequence is underway
• Host connected and plasma lit and running. Possible to run analysis of samples
• Instrument (FW) error causing a halt to analysis or restricting normal instrument operation, user intervention required to rectify the problem and regain error free status
• Note 4: this LED status has the highest priority (supersedes all others)
