Installation Instructions
Note :
l
Only Cognex-approved shielded cables should be used. See Accessories on page 8 for cable part
numbers.
l
Cable shields should be connected to the machinery’s potential equalization terminals in order to avoid
electrical current ground loops.
l
Cables should be routed in accordance with standard electrical wiring procedures in order to minimize
electrical noise.
l
The minimum bend radius of the cables is 80mm.
l
Cognex recommends the use of a separate power supply, either:
l
ACC-24I (DIN rail mountable, input 230VAC, output 24VDC/2A).
l
ACC-QUINT-PS (DIN rail mountable, input 230VAC, output 24VDC/5A).
1. Mount the sensor according to the mounting instructions, see Mounting the DS900 Series Sensor on page 20 .
2. Install the Ethernet interface hardware, if not already installed.
3. Install VisionPro software according to the instructions of the VisionPro documentation.
4. Make sure that your license is installed and valid.
5. Connect the DS900 Series Sensor to the PC via Ethernet.
6. Switch on the power supply (only applicable if not using PoE for power).
7. Open the Cognex GigE Vision Configurator PC application.
8. Check that the device is recognized by the PC. This may take a few seconds.
The "state" LED indicates different error conditions by flashing. If several errors occur at the same time, it indicates two of
them alternately. Therefore the LED can continue to flash for some time after the rectification of an error. If no flashing
occurs for several seconds, no error has occurred. For the error codes, see Error Codes on page 39 .
Note : A DS900 series sensor achieves highest precision measurements after it has been turned on for at least 20
minutes.
