8-1 Safety notes
The diffuse reflective sensors in the E3NT type series may only be
used as described in these operating instructions.
They may only be operated as part of a higher-level overall system,
e.g. of a machine installation.
Diffuse reflective sensors in the E3NT type series must not be used as
safety components within the scope of the EU machine guideline.
Their use is not permitted in applications in which the safety of persons
depends on functioning of the sensor!
8-2 Switching on the operating voltage
After the operating voltage has been switched on, the sensor runs a power-on
reset with a self-test.
The sensor displays the current distance from the measured object if the self-
test is successful.
0--0
is displayed if the sensor does not detect a measured object.
The flashing display
----
appears in the event of a short-circuit at the
outputs.
The sensor continues normal functioning once the short-circuit at the
outputs has been remedied.
