Viewing the Cable System Battery Status

The percentage of required voltage will be displayed in the top left window of the remote display for 2 seconds when the transmitter’s temperature increases by 4°C, which will be displayed in the top right window. To manually access the voltage status, turn the remote display off and on and observe the top left window after the firmware version is displayed. The voltage status is displayed in percent remaining (above the minimal necessary voltage) and is based on a 28V DC power source. Therefore, 28V will display as 100%, 19V as 50%, 12V as 25%, 9V as 0%.

When a standard DCI battery pack is installed into the remote display, rather than the Cable Transmitter Power Supply, it will automatically switch from the cable transmitter mode. Pitch, roll, temperature, and battery status will again be received by telemetry from the DigiTrak Receiver.

Operation

The cable transmitter is located using the FNLP, RNLP, and PLL in the same manner as other DigiTrak Transmitters, except the receiver will not display the transmitter’s pitch, roll, and battery or temperature status—this information is displayed only on the remote display. Many cable bores do not allow walkover locating; therefore, the depth of the transmitter is often calculated using the pitch information (see “Running off Pitch or Calculating Depth from Pitch” in the Locating Section) or by using the real-time DataLog System.

With the cable transmitter inside the housing/tool and grounded to the drill, complete a 1-point calibration procedure. Ensure that there are no metal objects between the tool and the receiver during calibration. Check depth readings against a measuring tape at varying distances from the cable transmitter. Calibration can be done with the housing tool installed on the drill rig. The pitch angle does not affect calibration.

Note that, because the cable transmitter emits twice the signal strength of a long-range transmitter (DX, DXP, D4X, D4XP), the receiver will be saturated with signal at distances closer than 60 inches (152 cm). Therefore, it may not be possible to obtain a depth reading at distances less than 60 inches (152 cm). To determine the maximum depth range of the cable transmitter, move the receiver away from the transmitter until the depth becomes very unsteady or reads “1999”. Although the depth of the tool can be calculated from the pitch information, it will not be possible to locate the tool by walking over it at depths greater than the maximum range. The ability to locate the FNLP and RNLP is also dependent on the maximum depth range.

Ensure that the remote display and power supply are connected directly to the power source, not through the drill’s DC power supply.

A multimeter should be available for power testing/troubleshooting. For detailed instructions on trouble- shooting the Cable Transmitter System, please contact Customer Service at 425-251-0559 or 800-288- 3610.
