Connect pin 8 with pin 12 to switch on the laser.
If you open this connection
the laser switches off,
-
the error output switches on,
-
the “State“ LED switches off.

Circuit for laser off, analog scaling and trigger input
Fig. 6:
Input for Analog Scaling and Triggering
5.2.2
If pin 9, see Fig. 6, is selected as input to scale the analog output in the sensor configuration (Chap. 8.3.14)
and if pin 9 is connected with pin 12 more than 2 sec, the scaling of the analog output starts, see Chap. 6.2.
The minimum pulse duration is 30 ms, see Fig. 11.
This external input can be configured as a trigger input to output the measurements also. If pin 9 is con-
nected with pin 12 measurements are output at the serial or analog output. The maximum trigger frequency is
500 Hz.
Trigger conditions:
Wiring
connect with ground, e.g. a relay or open-collector (NPN)
