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 218). Then try a firmware update (see “Replacing
Module Firmware” on page 162). If this does not help, a main board
replacement is required.
