6.5.5 Sync-In / Trigger
The measurement and signal output can be interrupted with the Sync-In input by connecting with high. As long
as Sync-In stands at high, the sensor delays the next measurement (Hold) and reduces the power of the laser
beam.
• The sensor checks the Sync-in before each measurement
• The previous measurement cycle will be always completed, even if the sync-in is High
•
The sensor reduces the power of the laser beam during the waiting period (Hold)
•
The outputs are held in the last valid state during Hold
• To come back to measuring mode, the Sync-In has to be set from High to Low
•
The Sync-in must be at least 5 μ s at Low to come back to the measuring mode
Sync-In Level Measurement
Sync-In low 0...2.5 V Run
Sync-In high 8 V…UB (operating voltage) Hold
Example: Mutual interference
Only the laser beam of Sensor1 may be in the measuring field of Sensor1. The laser beam of Sensor2 must
be outside the measuring field from Sensor1.
If it is not possible to prevent several sensors from affecting each other through appropriate installation, the
sensors affecting each other can be operated asynchronously by the Sync-In cable. The superordinate control
generates the signals for this.
HINT
Once the Sync-In is set to High (Hold), all output functions are frozen in their last state until
the next measurement.
