IndraControl L40 Structure of the Rexroth Inline Terminals 9-13
DOK-CONTRL-IC*L40*****-PR03-EN-P
9.8 Diagnostic and Status Indicators
For quick failure diagnostics on site, the IndraControl L40 and all modules
are equipped with diagnostic and status LEDs.
The diagnostic indicators (red/green) provide information on the failure
type and location. A module operates faultlessly, when all of its green
LEDs are lit.
After correction of the failure, the indicators immediately show the current
status.
The status indicators (yellow) show the state of the pertinent input/output
and/or the connected unit.
Note: Please refer to the functional description for information on the
diagnostic and status indicators provided on a specific module.
