is connected to GND.
Once the operating voltage has been switched on the sensor runs through an initialization sequence. This
is indicated by the momentary activation of the "State" LED. If initialization has been finished, the sensor
transmits the info string once in ASCII format via the serial interface independent of the selected interface.
The initialization including the info string transmission takes up to 5 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 15 minutes.
Once this has elapsed the sensor will be in measurement mode and, in accordance with the factory settings,
only the "State" LED is illuminated.
If the "State" LED is off, this means that

Operation

Getting Ready for Operation

Install and assemble the optoNCDT1402 in accordance with the instructions set out in Chapter 5.1, and
connect it with the indicator or monitoring unit and the power supply, having full regard to the connec-
tion instructions set out in Chapter 5.2.

either there is no operating voltage or
the laser has been switched off.
Nominal value: 24 VDC (11 ... 30 V, max. 50 mA).
Use the power supply unit for measurement instruments only, and not for drive units or similar sources of
pulse interference at the same time.
Switch on the power supply unit, if wiring is done.
