9.3 Indications of the LEDs
9.3.1 MS LED
Figure 59: MS LED
The Fle
xi Loop nodes and the Flexi Loop accessory have an LED
10)
which indicates the
communication status and the status of the Flexi Loop node. The designation MS =
module status comes from the Flexi Soft safety controller.
The indications on the LED have the following meaning:
MS Meaning
 Gr
een
The safe sensor cascade is in operation on this and all downstream nodes
and on all Fle
xi Loop accessories. No error occurred.
On the FLN-EMSS0000105, FLN-EMSS1100108, FLN-OSSD1000105
and FLN-OSSD1100108 Flexi Loop nodes:
If both EMSS LEDs or both OSSD LEDs are not constantly illuminated
green on this node, then the safe sensor cascade has been shut down by
this node.

No operating voltage, or voltage too low
