Triggering

The measuring value output on capaNCDT 6240 is controllable by an external electrical trigger signal. Here, only the digital output is
affected.
Triggering release by:
- Trigger input (pin 3 and pin 4 on 4-pole power supply
connector or
- U , HIGH 2,0 V

The trigger type is determined by the cparameters of the PROFINET device used.
Level triggering (high level). Continuous measurement output
with adjusted data rate, as long as the selected level is active.
After that the controller outputs the last value. The measured
