Delta CS24D - Manual (Page 32)

Time: There is a certain amount of reading variation over time, typically a few tenths of
a percent per week or less. This effect is compensated for in the CS24D.
12. Troubleshooting
The CS24D's indicator LEDs provide helpful troubleshooting information. The output
LEDs use binary coding to indicate which channel is active. (In Teach mode, the Output
LEDs show the output being taught, not the actual output state). The chart below shows
the operation of the indicator LEDs on the CS24D:
Condition RUN LED Output LEDs
No Power Off Off
Run mode, No Match Steady Blue ALL Off
Run mode, Match Steady Blue Steady Green shows Match Output
Teach mode, No Output Selected Blinking Blue ALL Off
Teach mode, Output Selected, No
Teach commands Blinking Blue Blinking Green shows Selected Sort Output
Teach mode, 1 - 7 Teach commands Off Blinking Green shows Selected Sort Output
Teach mode, 8 Teach commands Blinking Blue Steady Green shows Taught Sort Output
(The blink rate of the LEDs is about 2 times per second).
If the CS24D is not operating correctly, check for:
1. Dirt buildup on the window
2. Incorrect sensor to target distance
3. Problems with power supply or wiring
Use ColorSense to view data and see how close the match is. If the CS24D seems to be
operating correctly and is still misreading target colors, the sensor may need to be
retrained. (See Teaching section).
13. Support
Delta offers extensive telephone support on all of its products, both before and after
purchase. 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.
14. Repairs
If a CS24D 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.
