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.
• A red-blinking (modules with on-board LAN) or yellow-blinking (modules
without on-board LAN) indicator indicates that the module is in resident
mode (e.g. during update of main firmware).
• A fast red-blinking (modules with on-board LAN) or fast yellow-blinking
(modules without on-board LAN) indicator indicates that the module is in
boot loader mode (e.g. during update of main firmware). In such a case try
to re-boot the module or try a cold-start.
