For power supply specifications please refer to chapter 14.
Activation input InAct
The activation input is used to switch the laser on and off via the process control. The sensor
stops outputting data and does not respond to trigger commands or the trigger input. The
equivalent circuit of the inputs at X1 is shown in figure 6.6.
Trigger input InTrig
The trigger input is used for synchronizing the measurement with the process and for
synchronizing cascaded sensors. Detailed information on this topic can be found in chapter
4.2.3 and chapter 4.2.4. The internal equivalent circuit is shown in figure 6.6.
