MS LED
Meaning
–
Node not found (not connected, not in opera‐
tion)
Green
–
OSSD or EMSS ON
Green
–
OSSD or EMSS OFF
Red
–
Sequence error has occurred at node
Red
–
Discrepancy error has occurred at node
Green (2 Hz)
Red / green (2 Hz) Node found, corresponds to expected configu‐
ration.
11)
Red / green (2 Hz)
Red / green (2 Hz) Node found but does not correspond to config‐
ured type or number of configured nodes has
been exceeded.
11)
Red (2 Hz)
Red / green (2 Hz) Configured node not found
11)
Red / green (1 Hz)
Green (0.5 Hz)
Node found, but safe sensor cascade inter‐
rupted (cable break detected).
If multiple LEDs are flashing: The connection
has probably been interrupted downstream of
the Flexi Loop node whose LED is the last one
flashing.
Red (node 1)
Green (0.5 Hz)
Permissible number of Flexi Loop nodes under‐
shot
Red (node 32)
Green (0.5 Hz)
Permissible number of Flexi Loop nodes
exceeded

Operating mode LED
Meaning
Detection of operating mode (initialization)
Or:
No supply voltage or supply voltage too low
Green
Safety controller found and synchronized, Flexi Loop DIAG acces‐
sory in transparent mode
