Switching on the Power Supply Respectively PC
Switch on power supply respectively PC after completion of wiring.
The initialization including the info string transmission takes up to 10 seconds. Within this period,
the sensor neither executes nor replies commands.
To be able to produce reproducible measurements the sensor typically requires a start-up time of
20 minutes.

Limit value
The switching outputs are activated
(conducting to GND),
- when the target is outside the
measuring range,
- there is no target present
- or if a target is unsuitable (too
dark, polished metal, insufficiently
reflective).
The following 4 values are used:
- Upper limit (UL), --
- Lower limit (LL), --
- Upper hysteresis value (UH), --
- Lower hysteresis value (LH).
Function
- Mastering
- Limit control
Please refer to the instruction manual for factory settings to the limit and hysteresis values.

The transistor T is conductive in the
active state. The switching outputs are
short-circuit-proof.
To reset the short-circuit protection:
- Clear the external short circuit,
- switch off the sensor and switch on
again or
- send the software command „Reset“
to the sensor.
The two limit outputs may also be actu-
ated in parallel as window comparator
(OK/Not OK separation).

You can read more information about the sensor in the instruction manual. You will find these on-
line at www.micro-epsilon.de/download/manuals/man--optoNCDT-1700--en.pdf or on the delivered
CD.
