Diagnostics and troubleshooting
Raman RunTime provides diagnostic information to help determine troubleshooting required on the analyzer. Refer
to the System warnings and errors section of the Raman RunTime Operating Instructions (BA02180C) for additional
information.
9.1
Warnings and errors
9.1.1
System status
The Status button in the middle of the main view Status bar displays the current state of the system.
Symbol
Description
When the system is fully calibrated and operating as expected, the Status button in the middle of the main view
status bar reads OK and appears Green.
If a system warning is encountered, the Status button changes to Yellow. Warnings should be acknowledged but
immediate action may not be necessary. Click the Status button to view details of the warning. The most common
warning occurs when all the channels are not occupied. The button pulses continuously until the problem is resolved.
Click the Status button to view details about the warning.
If a system error is encountered, the Status button changes to Red. An error requires immediate action to restore
system performance.
Click the Status button to view details about the error.
9.1.2
Uncalibrated channels
In some cases, users may choose not to utilize all available channels on a Raman Rxn2 analyzer. These
unused/uncalibrated channels may result in warnings generated, thereby putting the whole system in a warning
state. To resolve these erroneous warnings about unused channels not being calibrated, the user can individually
turn off unused probes/channels in the Options > Calibration screen and select the ON/OFF marker beneath each
probe's number.
If a system error is encountered, the Status button changes to Red.
1. Click the Red status indicator to view details about the warning or error.
2. In the event the analyzer stops communication with the interface, go to Options, select System, choose Restart
and the analyzer reboots. This re-establishes camera/interface communication.
9.1.3
Low laser power
To check laser environment data, go to the Options > Diagnostics > Environment tab.
If low laser power is suspected due to low signal in the Raman spectra, check the Laser Power diagnostic as
highlighted in the figure below. The laser power should register within 10 mW of the laser power setpoint.
Laser diode current increases over time due to normal diode aging. Raman RunTime provides a warning when laser
diode current reaches 80 % of its current limit, and an error when it reaches 90 % of its limit. In each state Raman
RunTime recommends service of the laser module. When the laser diode current reaches its limit, the laser is in a
failure state and laser power gradually starts decreasing. For Technical Service, refer to our website
