The operation of the proximity switch is maintenance-free. For a cor-
rect function ensure:
• The active face and the open space should be kept free of deposits
and foreign bodies, particularly for mounting with the sensing face
showing upwards.
The red LED indicates no malfunction of the unit, it indicates that
the internal sensor signal is near the switching threshold.
2 cases can be distinguished:
• Normal operation/safe operation
The red LED is lit temporarily during the change between "object"
and "no object".
• Warning of possible malfunction
If the red LED is lit continuously, the operating conditions are no
longer optimum.
For example a change of the sensing range caused by deposits of
dirt can be detected.
You can take preventive measures to avoid a malfunction. For exam-
ple readjust or clean the unit.

Flashes or 7 Hz signal of the function check output =
internal fault, adjustment error.
Flash at the same frequency (2 Hz) = output shorted.
