6.8. I/O Test
This function manually changes the output of the Sensor. As a result, it possible to test whether the further pro-
cess is working as desired. The test is automatically terminated once you leave the test menu.
This occurs automatically after no keys have been activated for a period of 10 minutes.

Measured value:
Default of a measured value in µm
Statusbits:
The number of the status bit to be set can be selected by
pressing the “+” or “–” button. (see list of Statusbits)
Warm-up:
Default of the warm-up on “ok” or “warm-up”
Signal strength:
Default of the signal strength on “ok”, “too low” or “too high”
Temperature:
Default of the temperature on “ok”, “too low” or “too high”
If the Sensor returns to the display view after 30 seconds without pressing the button while the test is still active,
this is indicated by a
in the display view.

General error
One of the following bits is set.
—
2
Distance to object too
small
The current measured value is below the
working range.
Measuring range lower
limit
3
Distance to object too
large
The current measured value is above the
working range.
Measuring range upper
limit
4
No signal
The sensor does not detect an object
within its working range.
Measuring range upper
limit
5
Signal too weak
Too little light is reflected back to the sen-
sor from the object (e.g. very dark surface).
The quality of the measured value is re-
duced as a result.
Current measured value
6
Signal too strong
Too much light is reflected back to the
sensor from the object (e.g. reflector) The
quality of the measured value is reduced
as a result.
Current measured value
7
Warm-up procedure
The sensor is currently in the warm-up
phase and the quality of the measured
value does not yet comply with the speci-
fied technical data. See page 5 below.
Current measured value
8
Temperature too high
The sensor is at the upper limit of its tem-
perature range. If temperature continues to
rise, the sensor may be destroyed.
Current measured value
9
Temperature too low
The sensor is at the lower limit of its tem-
perature range. If temperature continues to
drop, the sensor may be destroyed.
