  • Page 18: Digital Inputs/Trigger

    You can define the sources for the triggering and if necessary the logic and debounce for the digital inputs. You can also define whether the laser in the LMS400 is switched on by a trigger or remains switched on continuously.
  • Page 19 3.7.3 Digital inputs The digital inputs 1 and 3 (IN1 and IN3) are used for triggering the LMS400, for example using external switches or sensors. To bridge bounce times on external switches, you can configure an input delay for the inputs. For both inputs you can also select whether they are to be active high or active low.
  • Page 20 LMS400 laser measurement sensor 3.7.4 Gate The LMS400 provides several trigger sources for gate control. These can start or stop the measurement immediately or initiate a delayed start and/or stop of the measurement. On this subject please read section “Control of the measurement process using a gate”...
  • Page 21 Note The LMS400 can count a maximum of 30000 encoder pulses from the time the trigger is activated until the lasers are switched off. With the encoder resolution of 0.2 mm/incr. of the recommended encoder this results in 30000 × 0.2 mm = 6000 mm.
