Cleaning Instructions
Cleaning Instructions:
1. Begin by removing the sensor lid's 4 screws with a 1/16" L wrench.
2. Gently lift the sensor's circuit board out by grasping the switch and pulling upward. Do not
remove the insulation tape.
3. Clean the lens of the sensor's photo eye with a clean soft cloth moistened with 99%
isopropyl alcohol (available from most electronics supply & tool distributors - e.g. Techni-
Tool, Contact East, Jensen Tools, Future Active, etc.)
4. Lightly scrape off sticky label residue using an Xacto knife with a #17, #18, or #19 chisel
blade. The CS2000 has double hard anodizing that is not easily penetrated, but
nonetheless, care should be taken when using the Xacto knife.
5. Fold the cloth over a couple of times to make it thicker. Saturate a 2" x 2" area on the
edge of the cloth with 99% isopropyl alcohol.
6. Insert the wet area of the cloth into the throat of the sensor. Pull the cloth back and forth
(like shining shoes) to loosen up the sticky residue.
7. Repeat steps 4 through 6 as necessary until all traces of residue have been removed.
8. Insert a cotton swab dipped in 99% isopropyl alcohol into the hole on the top half of the
sensor's case intended for the photo eye.
9. Rub the lens of the photo emitter (located on bottom half of sensor case) with the cotton
swab to remove any residue present.
10. Verify that the insulation tape is still in place and re-install the sensor's circuit board.
11. Re-insert the sensor's cable into the strain relief slot located in the top/rear of the case.
12. Re-install the sensor's lid making sure the cable is pinched tight and cannot be pulled out.
