Testing Cables

Speed Sensor Extension Cable

Disconnect the extension cable from the speed sensor assembly cable. Hold the extension cable connector so

that the keyway is pointing in the 12 o’clock position as shown below.

FIGURE 1. Speed Sensor Extension Cable Pin Diagram

Note: If a radar type speed sensor is used, the voltage between the 10 o’clock and 2 o’clock positions

may read 12 VDC.

If a +5V DC voltage reading is not present, disconnect the flow meter cable and re-test the speed

sensor cable. If the voltage reads +5V DC when the flow meter cable is disconnected, test the flow

meter cable per Testing the Flow Meter/Encoder Cable section on page 188.

Testing the Speed Sensor Extension Cable

1. Enter a speed cal of 9999 by touching the Speed button on the Product Control screen.

2. Zero the odometer by entering a zero value in the Distance button.

3. With a small jumper wire (or paper clip), short between the 10 o’clock and 6 o’clock sockets with a ‘short-no-

short’ motion. Each time contact is made, the distance total should increase by increments of 1 or more.

4. If the distance total does not increase, remove the section of cable and repeat the test at the connector that

is the next closest to the node. If the distance total now increases with the short-no-short test, replace the

defective cable as required.

5. If no pulses are registered, perform the above voltage checks.

6. If all of the cables test ‘good’, replace the speed sensor.

Note: After testing is complete, re-enter the correct speed cal before starting an application.
