CS475, CS476, and CS477 Radar Water Level Sensor

The electronics module is replaced by doing the following steps (see Figure 7-

1 and Table 7-5):

1. Unscrew the housing cap (cap is not shown in Figure 7-1).

2. Remove all wires that are attached or plugged into the electronics and note

their location for reassembly.

3. Loosen the two (2) screws “A” securing the electronics to the housing.

These screws are captive screws and will remain nested with the

electronics.

4. Gently remove the electronics “B” from the housing.

Some friction is normal when removing the electronics because a

seal is between the electronics and the lower portion of the

housing.

NOTE

5. Replace the electronics with a new module.

Make sure the two (2) screws holding the electronics module in

are tight, but do not over tighten. Over tightening these screws

can strip the threads.

NOTE

6. Tighten the two (2) screws “A” to secure the electronics to the housing.

7. Re-assemble all wires that were originally attached or plugged into the

electronics.

8. Tighten the housing cap.
