Photosensor
Normal operation:
•
Photosensor plugged into the Primary print head.
•
The photosensor green power on LED is illuminated.
•
The photosensor yellow detect LED illuminates when an object is held between 5 mm - 100 mm (0.2 in - 4 in) from the face of the sensor.
Do the following test to determine if the photosensor operates correctly for the application.
1. Place a representative object between 5 mm - 100 mm (0.2 in - 4 in) in front of photosensor; photosensor should sense object.
2. Place object on far guide rail; photosensor should not sense object.
3. Check that objects on the far side of conveyor do not trip the photosensor.
4. Check that color differences in product do not cause multiple photosensor trips at the farthest sensing distance.
NOTE:
The test object should be a sample of the actual product.
NOTE:
If the green power LED or yellow LED on the photosensor fails to illuminate when an object is placed in front of the photosensor, it
indicates that the photosensor and / or power supply is disconnected, or the power supply, CPU, or photosensor has failed.
Encoder
Ensure the encoder is plugged into the Primary print head.
Navigate to the NextControl status screen. If the line speed displays a value comparable to the known line speed, then the encoder is functioning
correctly. If the line speed displays "0", then check electrical connections to the encoder and PCB. Refer to
Create & Control manual 400463
