DIGITAL CONTROL INCORPORATED Transmitter Types of Eclipse Transmitters DCI manufactures four different battery-operated Eclipse transmitters—a standard transmitter (black tube), a short-range mini transmitter (gray tube), a long-range transmitter (light-gray tube), and a dualfrequency transmitter (lavender tube). We also offer a cable transmitter (see Cable System section for information on the cable transmitter).
Transmitter Long-Range Eclipse Transmitter The long-range Eclipse transmitter emits a 12-kHz signal and provides a depth range of approximately 85 ft (25.9 m). The long-range transmitter is 19.00 in. (482.6 mm) long and 1.25 in. (31.8 mm) in diameter. This transmitter requires the use of one 3.6-V DCI SuperCell Lithium Battery. The use of two C-cell alkaline batteries will result in very short battery life—approximately 2 hours.
Transmitter Batteries The 15.00-in. (381.0-mm) transmitters require two C-cell alkaline batteries or one DCI SuperCell Lithium Battery. The 19.00-in. (482.6-mm) long-range transmitter requires one DCI SuperCell Lithium Battery, although two C-cell alkaline batteries will work for a very short period of time. The mini transmitter requires one AA alkaline battery. DCI does not recommend using non-alkaline or rechargeable batteries.
Transmitter Start Up and Frequency Modes Starting the Standard Eclipse Transmitter 1. Remove battery cap, and load two C-cell alkaline batteries (or a SuperCell lithium battery) into the battery compartment, positive terminal(s) first. 2. Replace the battery cap and screw it in until it is flush with the end of the battery compartment. 3. To view the transmitter information, select Locate from the main menu screen on the receiver, and click the trigger. 4.
Transmitter Starting the Eclipse Dual-Frequency Transmitter The Eclipse dual-frequency transmitter can be set to transmit in two different modes—dual-frequency mode (transmitting at 1.5 kHz and 12 kHz) or single-frequency mode (transmitting at 12 kHz). The frequency mode can only be changed at startup when the batteries are loaded. You cannot change the frequency mode of the transmitter while drilling.
Transmitter Starting the Dual-Frequency Transmitter in Single-Frequency Mode 1. Remove the battery cap, and hold the transmitter vertically with the battery compartment down and the front end pointing up (see diagram). 2. Load two C-cells (or a SuperCell battery) into the battery compartment with the positive terminal(s) entering first. 3. Replace the battery cap while rotating the transmitter in this vertical position until the cap is flush with the end of the battery compartment. 4.
Transmitter For the mini transmitter (8.00 in./203.2 mm long), each slot should begin at least 1.25 in. (32 mm) from the front or index cap end of the transmitter and must be at least 3.75 in. (95 mm) long (see figure below). Slot Position Battery Compartment End Index Cap End Slot Length 1.25 in. 3.75 in. (95 mm) (32 mm) Mini Transmitter Housing Slot Requirements For the long-range transmitter (19.00 in./482.6 mm long), each slot should begin at least 2.0 in.

DIGITAL CONTROL INCORPORATED Locating The graphic display on the Eclipse receiver uses icons to show readings and system status information. The locate mode screen provides real-time data about the transmitter’s temperature, frequency mode, pitch, roll, and signal strength, in addition to displaying the channel setting. Pitch Frequency Mode Transmitter Temperature Clock/Roll 7.
Locating Locate Points (FLP & RLP) and Locate Line (LL) Three positions or locations within the transmitter’s field are used to locate the transmitter below ground. Two of these locations represent extensions of the transmitter. One point is in front of the transmitter (the front locate point or FLP), and the other is behind the transmitter (the rear locate point or RLP). The third location is a line that represents the position of the transmitter.
Locating Locating Procedure The Eclipse system can be used to locate the transmitter while facing either toward the drill or away from the drill. The locating procedure given here assumes you are facing away from the drill with the transmitter out ahead of you. 1. Begin locating by clicking the trigger after you have selected the Locate option from the main menu screen. The locating display will appear, as shown in the graphic on the left below.
Locating NOTE: To ensure you are over the RLP, you can rotate the receiver 360°, being careful to keep the receiver display at the center of the rotation. The target should stay in the same position in the box on the receiver’s display. If it does not, then the receiver’s antenna may be malfunctioning—you should contact DCI Customer Service, 800-2883610 or 425-251-0559, for assistance. 3.
Locating 6. Continue to walk out ahead of the transmitter and position the receiver until the target is in the box as shown below. FLP 7.5% SH LL RLP 75°F CH:B1 433.5 Actual Position of Receiver and Transmitter Eclipse Locating Display with Target in Box at FLP 7. While at the FLP, hold the trigger in to observe the predicted depth (11 ft 8 in.
Locating 8. While standing on the FLP and facing back toward the drill, it is possible to “sight in” or align the FLP with the RLP. This axis line is at a 90° angle (perpendicular) to the LL. Where this axis line crosses the LL is where the transmitter will be found, below ground. 9. Position the receiver at the intersection of the LL and the line between the RLP and FLP—you will be above the transmitter. From this location you can observe the depth of the transmitter by simply holding in the trigger.
DIGITAL CONTROL INCORPORATED ® The Target Steering Function The Target Steering® function allows the Eclipse receiver to be placed out ahead of the drill head and used as a steering target. To activate the Target Steering function, you must program the receiver with the desired target depth number. The drill head can then be guided to a point directly below where the receiver has been placed. The Eclipse system assumes level topography for the most accurate Target Steering results.
Target Steering The maximum distance that the Eclipse receiver can be placed out ahead of the drill head for Target Steering is 35 ft (10.7 m). Over this 35-ft range, the following parameters apply: ¾ ¾ The maximum depth change is approximately 4 ft (1.2 m). The maximum pitch change is approximately 14%. To determine if your desired target depth is feasible: 1. Use the Eclipse receiver to obtain the current transmitter depth with respect to level ground surface. 2.
Target Steering 4. When you have entered the correct target depth number, click the trigger. When the target depth is programmed and you are in locate mode, you will see a “T” (for target) next to the channel setting in the lower left corner. 7.5% SH 75°F CH:B1T 411 “T” Indicates Target Depth Is Programmed Receiver Screen with Target Depth Programmed NOTE: If you are not using the target depth mode, you should set the target depth to 0.00.
Target Steering Steering to the Target Once the target depth number has been entered on the receiver and the receiver is in position as the target, select Remote from the main menu screen on the remote display to see the Target Steering screen, as shown below. The steering indicator in this case shows that the drill head is to the left and too high for the intended path. The steering indicator should be dead center in the display if you are correctly heading to your programmed target depth.
DIGITAL CONTROL INCORPORATED Cable System Remote Display Power Supply Cable Transmitter Extraction/ Insertion Tool Eclipse Cable System The Eclipse cable system is designed specifically for bores that: ¾ ¾ ¾ ¾ Have depths in excess of 50 ft (15.2 m). Have lengths that require several days to drill. Do not allow walkover locating. Are in high-interference areas. The depth and locating ranges of the Eclipse cable system are both approximately 80 ft (24.4 m).
Cable System Power Supply – This unit is inserted into the battery compartment at the back of the remote display. It is hard wired to the Eclipse cable transmitter with a 10-gauge (white) wire and to the power source with a gray cable that contains 14-gauge black and red wires.
Cable System Power Source – Lead-acid automotive batteries that supply between 12 and 28 V DC are used for the power source. For bores shorter than 1000 ft (305 m), one 12-V battery will suffice. If the bore length increases beyond 1000 ft (305 m) or advance rates decrease, additional batteries may be added in series (see diagram).
Cable System Connecting Power Supply to Power Source and Cable Transmitter The gray wire that extends from the power supply has two wires within it—a red wire and a black wire. The black wire is the ground; it connects to the negative battery terminal, and the red wire connects to the positive battery terminal. The white wire connects to the cable transmitter wire (see diagram).
Cable System Cable Transmitter On/Off Before you can power up the remote display, you must ensure that the power supply, power source, and cable transmitter are properly connected, as discussed in the previous sections. After properly connecting the cable system, push the execute button to power up the remote display. Then select the Cable menu option. This will enable the remote display to send power to the cable transmitter.
Cable System 4. From the main menu on the remote display, select Cable and press the execute button. 5. Press the right arrow, and press it again to select Y for yes, then press the execute button. Note the “RO” or roll offset number that appears at the top of the remote display to indicate that a compensation for the transmitter’s roll position has occurred.
Cable System Viewing Status of Cable System Power Source The battery status of the power source will display at the bottom of the remote display screen where the transmitter battery status normally displays. When the battery status symbol appears 100% full, the battery is delivering at least 16 V of power. When the symbol is 50% full, the battery power is 14.5 V. When the symbol appears to be 25% full, the battery power is 14.0 V. NOTE: If the power source is delivering less than 9.
