3D sensor
UK
7.1.1
Pin 1 / 3 (24 V / GND)
The permissible voltage range is indicated in the data sheet of the sensor.
7.1.2
Pin 2 (trigger input)
The image capture of the sensor can be triggered with a switching signal via the trigger input.
The following trigger edges can be used:
●
Falling edge triggers image capture
●
Rising edge triggers image capture
●
Falling and rising edges trigger image capture
Further possibilities to trigger the sensor:
●
Process interface command
●
Continuous image capture with fixed frame rate
The trigger input is internally debounced. Depending on the electrical installation debouncing of the
trigger wire is not necessary.
Internal debouncing prevents several short pulses from triggering. The pulse must be at least 2 ms
long to be recognised as a trigger.
7.1.3
Pin 4 / 5 / 6 (switching outputs)
The switching outputs 1 to 3 provide the different sensor statuses. Besides the sensor status the
switching outputs can also provide the reference values necessary to solve the application.
The electrical specifications of the switching outputs 1 to 3 are indicated in the data sheet.
Switching output 3 provides the sensor status "Ready for trigger" as default setting.
"Switching output switched" means that the respective sensor status has occurred.
Depending on the setting the sensor status can have one of the following values:
●
"Ready for trigger"
The sensor signals that a new image can be captured. Only with this sensor status trigger operations
are processed. For the continuous image capture the status "Ready for trigger" is not output.
●
"Image capture finished"
The sensor signals that the image capture is finished. The sensor status can be used for cascading
sensors.
●
"Evaluation finished"
The sensor signals that image processing is finished. At that moment the switching outputs are already
updated. The image data is transmitted via Ethernet.
●
"Error"
The sensor signals an internal error. Detailed information about errors can be requested via Ethernet.
