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