6 Troubleshooting and Diagnostics
Status Indicators
Module Status Indicator
The module status indicator indicates one of six possible module
conditions:
• When the status indicator is OFF (and power switch light is on), the
module is in a prerun condition, and is ready to begin an analysis.
• A green status indicator, indicates the module is performing an analysis
(run mode).
• A yellow indicator indicates a not- ready condition. The module is in a
not- ready state when it is waiting for a specific condition to be reached
or completed (for example, immediately after changing a set point), or
while a self- test procedure is running.
• An error condition is indicated when the status indicator is red. An
error condition indicates the module has detected an internal problem
which affects correct operation of the module. Usually, an error
condition requires attention (e.g. leak, defective internal components).
An error condition always interrupts the analysis.
If the error occurs during analysis, it is propagated within the LC
system, i.e. a red LED may indicate a problem of a different module.
Use the status display of your user interface for finding the root
cause/module of the error.
• A blinking indicator indicates that the module is in resident mode (e.g.
during update of main firmware).
• A fast blinking indicator indicates that the module is in a low- level
error mode. In such a case try to re- boot the module or try a cold- start
(see “Special Settings” on page 185. Then try a firmware update (see
“Replacing the Module’s Firmware” on page 135). If this does not help,
a main board replacement is required.
