Figure 5: Trigger
For operation, the sensor needs a trigger signal regarding the length of the print to be
evaluated for signaling the reading window. This is supplied to the sensor via Pin 5. The
start of the reading window is signaled by the rising edge of the trigger signal, the con‐
trol panel cannot be operated during this time. The end is signaled by the falling edge.
The associated output state change is present no later than 10 ms after the falling
edge. The process quality (quality of print) is displayed. When checking the print on
packaging and other objects, we recommend generating the trigger signal via a photo‐
electric sensor; if continuous material is used, the signal can be generated via a control
or a contrast sensor.
