750/752 Tracker - CONTROLS 7OVERVIEW750/752 Tracker - CONTROLS 7OVERVIEWCONTROLSOVERVIEWThe 750/752 Tracker performs well with a variety of beacons and can track shallow or deep bores. It can track both 12K and 29K beacons and send beacon information to a display mounted on the drilling unit operator’s station. The 750/752 Tracker can also locate lines and cables. Available modes are 8 kHz active (when used with transmitter) and 60 or 50 Hz passive (for locating power cables). A brief description of the buttons and display on the 750/752 Tracker follows.CONTROLSOVERVIEWThe 750/752 Tracker performs well with a variety of beacons and can track shallow or deep bores.

Tracker control, walkover beacon tracking and remote guidance work with 12K and 29K beacons.Potential radio frequency (RF) hazard. Operating this device within 8” (20 cm) of your body may cause RF exposure levels to exceed FCC RF exposure limits and should be avoided. This device must not be co-located with any other radio transmitter. The maximum antenna gain is 8 dBl.IMPORTANT: Large metal objects, rebar, power lines and any other kinds of interference can adversely affect depth estimates.BEACON TRACKING MODESSet-upYou must calibrate tracker to each beacon frequency before beginning a beacon tracking job. After calibration, tracker can estimate depths from approximately 9” (0.2 m) to 100’ (30.5 m) depending on beacon used. Keep the following in mind when calibrating system:• Beacon and tracker should not be moved or rotated until calibration is complete.• Only depth estimation is affected by calibration. Roll, pitch, left/right deviation, temperature, and battery status are not affected.• Large metal objects, rebar, power lines, and any other kinds of interference will adversely affect calibration.OPERATIONThe 750/752 tracker has four operation modes: tracker control, walkover beacon tracking, remote guidance, and line locating.

Install beacon into drill head and place on ground exactly 10’ (3 m) away from tracker. Make sure no metal objects including drilling unit and drill pipe are within 20’ (6 m) of tracker and toolhead. 3. Position tracker parallel to center of drill head.4. Turn tracker on and press and hold depth and up arrow keys until calibration mode is entered. Release keys.5. Verify calibration by moving tracker 15’ (4.5 m) away from toolhead. Check depth. If reading is not 15’ (4.5 m), recalibrate tracker.6. Repeat for other frequency, if needed.IMPORTANT: Some beacons transmit more than one frequency. Calibrate tracker for each frequency separately.Calibration Procedure1. Select beacon frequency, if necessary.2.

Place 86BG beacon into the housing and put the lid on the housing.2. Use the Smart tool according to the instructions included with the level.3. Use the Smart tool to level the housing to 0. 4. Using the tracker, check the pitch of the 86BG and make sure that it is ± 1% or lower. If the pitch is more than ± 1%, remove housing lid and adjust the beacon inside the housing to ± 1% or less and repeat steps 3 and 4. IMPORTANT: If the 86GB is not within ± 1% of zero, the tracker pitch will not calibrate.5. Once the housing is level and the 86BG is within ± 1%, push and hold the F/A/L/R button and press the down arrow key. This will reset the pitch shown on the tracker to zero.6. To revert to actual/pitch display, press and hold the F/A/L/R button and press the down arrow key, then press the up arrow key. This will reset the pitch display to show actual pitch rather than calibrated pitch.Grade Beacon Pitch Calibration1. Place 86BG beacon into the housing and put the lid on the housing.2.

Learn to use equipment correctly.This mode allows 750/752 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. Troubleshooting tip: If thrust and rotation do not work, check whether tracker control light on drilling unit is on. If it is, communication has probably stopped between tracker and display or tracker is set to incorrect code. If communication cannot be restored, install tracker control key on drilling unit. Tracker control light will go off and thrust and rotation will function. IMPORTANT: • Tracker operator cannot stop thrust and rotation from tracker with tracker control key installed in drilling unit and turned to disable position.• Tracker control mode is available on units with “TC” or “DF” at the end of their model descriptions.Tracker Control ModeOverviewIncorrect procedures could result in death, injury, or property damage.

Do not hold tracker at right angle to beacon.IMPORTANT: A common problem when locating a beacon is secondary or ghost signals. A typical beacon signal pattern shows a main signal and two weaker secondary signals. Track beacon at main signal. Familiarity with beacon signal pattern will lessen the effect of secondary signals. Also, the beacon tracking arrows will disappear when tracker is over secondary signal.3.When both fore/aft arrows are on, sweep tracker from side to side and use signal strength display to find lateral location of beacon (point A). 4.Step back until ghost is located (no arrows in center of clock face and low signal strength) and then move slightly forward until only one arrow is lit (point B). 5. Press fore/aft/left/right button to switch to left/right arrows and sweep tracker back and forth until both left/right arrows are on.6.
