Appendix A. Replacing the Cable
The sensor is fitted with a cable for connection to the datalogger. The
following procedure is for replacing the original cable (see FIGURE A-1 and
TABLE A-1).
1. Unscrew the housing side compartment screw cap.
2. Loosen the cord grip on the cable entry.
3. Remove approximately 4 inches (10 cm) of the cable mantle.
4. Strip approximately 0.4 inches (1 cm) of the insulation from the end of the
individual wires.
5. Insert the cable into the sensor through the cable entry.
6. Lift the opening levers of the terminals with a screwdriver.
7. Insert the wire ends into the open terminals.
• Connect the Power Supply +12 Vdc to the terminals marked 1 (+).
• Connect the Power Supply Ground to the terminals marked 2 (–).
• Connect the Data Line to the terminals marked 3 (data).
8. Press the opening lever of the terminal down. You will hear the terminal
spring closed.
9. Check that the wires are firmly connected in the terminal by lightly pulling
on them.
10. Connect the screen to the internal ground terminal and the external ground
terminal to potential equalization (ground).
11. Tighten the cord grip on the cable entry. The seal ring must completely
encircle the cable.
12. Place the housing side compartment screw cap on and tighten to ensure a
mechanical seal.
