12 to 36 VDC
WIRING TDR TO POWER SUPPLY
1. Turn off all power to unit.
2. Detach the cover of the unit.
3. Guide the cable into the housing through the cable gland
4. Remove a 0.16 in (4 mm) length of insulation from the wires and cut away the free part of the shielding.
5. Connect the wires of the current loop to terminals 2 and 3 (any polarity). See Figure 1.
6. Pull back the cable until 0.39 in (10 mm) of length remains in the housing behind the cable gland.
7. Tighten the cable gland using a wrench.
8. Check the connection of wires and the tightness of the cable gland.
9. Properly ground the unit. Screw type terminal on the housing, maximum cable cross-section: 0.006 in
mm
). Grounding resistance R < 1 ohm. The shielding of the signal cable should be grounded at the control
2
room. Avoid coupling of electromagnetic noises and place the signal cable away from power-current cables.
WARNING: UNIT HOUSING MUST BE GROUNDED FOR PROPER FUNCTION.
10. Return power to the unit.
11. If unit has been programmed by the company, it is now ready to begin taking
readings. If unit needs to be reprogrammed for the vessel, proceed to the Set Up
Section.
