Installation and Mounting5.3.1 Switching off the LaserConnect 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.+3.3 VILD1402Laser offTeach inPin 8Pin 9Pin 12330 OhmGNDFig. 7 Circuit for laser off, analog scaling and trigger input5.3.2 Input for Analog Scaling and TriggeringIf pin 9, see Fig. 7, is selected as input to scale the analog output in the sensor configuration, see Chap.8.4.16, and if pin 9 is connected with pin 12 more than 2 sec, the scaling of the analog output starts, seeChap. 6.2. The minimum pulse duration is 30 ms, see Fig. 14.This external input can be configured as a trigger input to output the measurements also. If pin 9 is connectedwith pin 12 measurements are output at the serial or analog output. The maximum trigger frequency is500 Hz.Trigger conditions:Wiringconnect with ground, e.g. a relay or open-collector (NPN)optoNCDT 1402Page 23
