750 Tracker - OPERATION BEACON TRACKING MODES 21 21 750 Tracker - OPERATION BEACON TRACKING MODES OPERATION The 750 tracker has four operation modes: tracker control, walkover beacon tracking, remote guidance, and line locating. Potential radio frequency (RF) hazard. Operating this device within 4 in (10 cm) of your body may cause RF exposure levels to exceed FCC RF exposure limits and should be avoided.
750 Tracker - OPERATION BEACON TRACKING MODES Calibration Procedure 1. Install beacon into toolhead and place on ground exactly 10 ft (3 m) away from tracker. Make sure no metal objects including drilling unit and drill pipe are within 20 ft (6 m) of tracker and toolhead. 2. Position tracker parallel to center of toolhead. 3. Turn tracker on and press and hold depth and up arrow keys until calibration mode is entered. Release keys. 4. Verify calibration by moving tracker 15 ft (4.
750 Tracker - OPERATION BEACON TRACKING MODES 23 750 Tracker - OPERATION 23 BEACON TRACKING MODES Troubleshooting If four dashes appear in the display, unit has not been calibrated or has been calibrated incorrectly, beacon is too close for depth estimate, or beacon is too far away for depth estimate.
750 Tracker - OPERATION BEACON TRACKING MODES Tracker Control Mode Overview Incorrect procedures could result in death, injury, or property damage. Learn to use equipment correctly. This mode allows 750 Tracker operator to disable hydraulic power to drilling unit thrust and rotation within 16 seconds. This mode will not stop thrust and rotation immediately. When tracker and display communications cease, green tracker control light on drilling unit will come on and thrust and rotation will be disabled.
750 Tracker - OPERATION BEACON TRACKING MODES 25 750 Tracker - OPERATION 25 BEACON TRACKING MODES Operation 1. Turn on drilling unit. Press and hold download button to display serial number on 750 Display. 2. Turn on 750 Tracker and check four-digit display code. • Hold fore/aft/left/right button and press mode to review and start sending code. IMPORTANT: Continue to hold down fore/aft/left/right button to adjust code.
750 Tracker - OPERATION BEACON TRACKING MODES 3. Remove tracker control key from drilling unit and keep in tracker operator’s possession. 4. Drill and track bore until drill head enters target pit or exits ground. 5. Turn off tracker. After 8-16 seconds, tracker control light on drilling unit will come on and hydraulic power to thrust and rotation will be disabled. 6. Change downhole tools. 7. If you are tracking backreamer’s path, turn on tracker and enable code transmission.
750 Tracker - OPERATION BEACON TRACKING MODES 27 27 750 Tracker - OPERATION BEACON TRACKING MODES Walkover Tracking Mode Location 1. Turn on tracker. Make sure you can see fore/aft arrows in center of display. If you see left/right arrows, press fore/aft/ left/right key. 2. Walk bore path with bottom of tracker parallel to beacon. Do not hold tracker at right angle to beacon. IMPORTANT: A common problem when locating a beacon is secondary or ghost signals.
750 Tracker - OPERATION BEACON TRACKING MODES Remote Guidance Mode Information is transmitted directly to display at drilling unit when tracker is in remote guidance mode. Approximate distance from tracker to beacon (not the estimated depth of the drill head) is shown every 5 seconds. Distance will not be correct within one and a half times the toolhead depth. For example, if you are drilling at 4 ft (1.2 m), you will be able to drill within 6 ft (1.8 m) of tracker.
750 Tracker - OPERATION BEACON TRACKING MODES 29 29 750 Tracker - OPERATION BEACON TRACKING MODES Displayed Information Beacons send a variety of information to tracker. All Subsite Electronics beacons send pitch, roll, temperature and battery information. Roll Beacon roll information is useful in determining the direction that the drilling tool will tend to travel when pushed without rotation. The following chart shows typical tool face roll indications for directional drilling.
750 Tracker - OPERATION BEACON TRACKING MODES Pitch Tracker shows pitch (% grade) when used with beacons that provide this information (see specific beacon literature). Pitch shows beacon grade in percentages from down arrow 99% (45 degrees down) to up arrow 99% (45 degrees up). Tracker displays this information to the left of roll display. Grade beacons will send pitch in 0.1% increments from 1-45% and in 1% increments from 45-90%.
