Quick Start Transmitter Battery Installation Transmitter Overview Induction Direction ➎ Dynatel™ 220M Frequency ƒ Hz Off On Output Level ➊ ➋ ➌ ➍ 1. Power OFF / Battery Level Indicator – Press and hold.. Display reads:. “OK” with solid tone = good. “LO” with pulsing tone = low. “- -” with no tone = replace 2. P ower ON / Frequency Select – Powers on the unit. When pressed repeatedly, it will cycle through the available frequency modes:. a. Single audio frequency - 8 kHz. b.
Warning Potential for electric shock exists when handling connection cables while the transmitter is ON. Make all connections prior to powering on the unit. Turn the transmitter OFF before handling connection cables. Warning Voltage greater then 240 volts will damage equipment and could cause personal injury or death. Make all connections before turning on the transmitter. Follow standard procedures for reducing the voltage.
Receiver Overview ➊ ➍ ➒ ➎ ➋ ➑ ➌ ➏ ➐ 1. Volume Control – Adjusts the volume of the receiver through three levels of audio and off. 2. Power Key – Powers the receiver on and off. 3. Peak Key – Toggles between Directional Peak and Single Peak antenna configuration. 4. Line Locate Key – Places the Receiver in Pipe/Cable locating mode and selects frequency. When toggled, it will cycle between 8 kHz, 82 kHz, and 60 Hz (Power Mode). (More frequencies are available in setup mode). 5.
Transmitter Operations There are three different methods of applying the transmitter’s locating signal to the target conductor: Direct Connection, 3M™ Dynatel™ Dyna-Coupler Clamp, and Induction. Direct Connection This is the preferred mode of operation because the transmitter is connected directly to a metallic portion of the target conductor (hydrant, meter, riser, valve, sheath, or tracer wire). 1. While the transmitter is off, plug the direct connect cable into the output jack of the transmitter. 2.
Induction Method If you cannot make a direct connection, or use the 3M™ Dynatel™ Dyna-Coupler clamp to apply a locating signal on the target, use the induction method. This method uses the internal coil of the transmitter to generate a magnetic field. This is the least preferred method of applying a signal on a target conductor because it can easily be picked up by other non-target conductors in the area. However, it is the preferred method of applying a signal to multiple cables/pipes in the same trench.
Receiver Operations Initial Settings From the manufacturing facility, the receiver is configured as follows: Line Locate Frequencies Selection Default 8 kHz Always Enabled Enabled 82 kHz Always Enabled Enabled Power Always Enabled Enabled Radio Enable/Disable Disabled CATV Enable/Disable Disabled CPS Enable/Disable Disabled 512 Hz Enable/Disable Enabled 640 Hz Enable/Disable Disabled 33 kHz Enable/Disable Enabled Units inch or cm Inch Power Frequency 50 Hz or 60 Hz 60 Hz
512 Hz – Sonde frequency indicated by sonde icon. Press the down key to enable/disable the frequency. A check mark will appear in the box when the frequency is enabled. 640 Hz - Sonde frequency indicated by sonde icon. Press the down key to enable/disable the frequency. A check mark will appear in the box when the frequency is enabled. 33 kHz - Sonde frequency indicated by sonde icon. Press the down key to enable/disable the frequency. A check mark will appear in the box when the frequency is enabled.
CPS – Cathodic Protection System– 120 Hz or 100 Hz (based on 60/50 Hz selection) Press the down key to enable/disable the frequency. A check mark will appear in the box when the frequency is enabled. 50 Hz / 60 Hz To change the power frequency selection, press the up (60) or down (50) key. The selected frequency will appear in the box at the center of the screen.
Line Locating Screen ➐ ➊ ➏ ➋ ➌ ➍ ➑ ➎ 1. Speaker Icon – Indicates audio level 2. Bar graph – Graphical representation of received signal 3. Peak Mode Indicator – Indicates single or directional peak mode 4. Selected Line Locating Frequency – Displays the frequency the receiver will detect 5. Line Locating Icon – Indicates line locating mode vs. sonde mode 6. Battery Icon – Indicates battery level of receiver 7. Directional Arrows – Left/right indicators for path tracing 8.
Pipe and Cable Locating 1. Press the on/off key. 2. Press the line key to match the frequency that the transmitter is sending. 3. Sweep the receiver across the area in a left right motion, while watching the bar graph, directional arrows, and signal strength. 4. When a magnetic field is detected, the bar graph will close, the signal strength and the audio will increase. 5.
Sonde Locating A sonde is a small transmitter that enables the user to trace metallic and nonmetallic pipes, sewers, drains, or ducts. It can also be used to find a blockage or collapse. Refer to sonde manufacturer’s guide for proper selection of sonde for the desired application. A representation of a sonde transmission field appears below. There are typically three peak signals present. The strongest peak signal is over the center of the sonde.
Pin-Pointing the Sonde Note: The receiver handle must be oriented perpendicular to the sonde. The cross bar of the receiver must be in line with the sonde (the opposite of line locating). 1. Set the receiver to Sonde mode by pressing the Sonde key until the frequency of the sonde appears on the locate screen. 2. Holding the receiver perpendicular to the suspected path, walk the path until the receiver detects the first peak signal of the sonde. 3. Adjust the gain down if the bar graph closes completely.
