Excessive current at the switching
output OUTx (see LED I/II).

Check switching output for short
circuit or excessive current. Re-
move the fault.

C.Loc

Parameter setting via pushbuttons
locked due to active IO-Link trans-
mission.

Wait until parameter setting via
IO-Link is finished.

S.Loc

any

Parameter setting via pushbuttons
disabled by software.

Unlocking only possible via IO-
Link interface/IO-Link parameter
setting software.

Process value too high (measured
frequency > 5000 Hz / > 300000
RPM).

Check connected sensor and val-
ue range.
