11. Troubleshooting
The CS64A's output indicator LEDs provide helpful troubleshooting information.
The green LEDs come on when the output voltage reaches approximately 2 volts and
gradually increase in intensity as the output voltage increases, so they should be at least
slightly on for all but very dark objects.
If the green indicator LEDs are off (or very dim), when light colored material is in the
normal sensing area, check for:
1. Dirt buildup on the window
2. Incorrect sensor to target distance
3. Problems with power supply or wiring
12. Support
Delta offers extensive telephone support on all of its products, both before and after the
sale. Delta offers testing of samples using color sensors or spectrometer. To have
samples tested, send them to:
On new applications, this testing is typically done at no charge. If required, training and
field support can be provided on a time and expense basis.
13. Repairs
If a CS64A needs repair, call Delta to receive an RMA number before returning unit.
Including a brief description of the problem will help to speed the repair time.
