Timing When An External Trigger Is Used - Baumer VeriSens ID Series Technical Documentation Manual

13.2 Timing when an external trigger is used

The sequence of the individual signals and their designation are indicated in the diagram below:

Following image acquisition, the Image trigger signal is deactivated. The Image trigger signal is activated
again at the end of image acquisition and another image acquisition operation is possible immediately.
The Pass/Fail signal then switches at the set output time even if additional analyses have already been
performed. The Result valid signal is active during this time.
NOTE
If you have connected an encoder, you may set the output time and duration as a
distance.
In addition, you can specify an "output run-up" in milliseconds to activate the Pass/Fail
signal before reaching a specific position. This option is available if an exact output time
has been specified and this is specified as a distance.
Keep in mind that, in this case, the conveyor speed must be constant!
