Installation and set-up / Operation / Maintenance

After mounting, wiring and setting check whether the unit operates
correctly.
When the supply voltage is applied, all LEDs light and go off one after
the other.* The unit is then ready for operation.
*During this time the output is switched according to the programming: ON
with the NO function and OFF with the NC function.
Failure indication: In the case of a short circuit the function indicati-
on and the red LED row are lit alternately.

Recommended maintenance

Check the sensor tip for build-up from time to time. Clean it with a
soft cloth. If necessary, build-up which adheres firmly (e.g. lime) can
be removed with a common vinegar cleansing agent.
