INTRODUCTION The 3M™ Dynatel™ 2210E Cable Locator consists of a Transmitter and a Receiver for locating buried cables or Active Duct Probes (sondes). It also can be used to identify cables or pairs using a Dyna-Coupler plugged into the Receiver jack. The Transmitter provides two frequencies to accommodate varying factors such as distance, cable type, or soil conditions. The Receiver detects 50 or 60 Hz AC Power signals and low frequency (LF) radio signals re-radiated form local broadcast transmitters.
INITIAL RECEIVER CONFIGURATION Display depth units (inches, feet and inches, or centimeters) may be changed while holding and pressing . For each press, one of three units will display. To change the passive Power frequency, press and hold then press to toggle between 50 or 60 Hz as displayed in the lower left corner of the display.
TRANSMITTER BATTERY TEST To test the Batteries, hold down and listen to the tone (solid tone=good; beeping tone=low; no tone=replace batteries). Note: The battery test indicates battery condition for normal output levels. If the unit resets when the high output level is selected, use the normal output level or replace the batteries. LOCATING A BURIED CABLE Transmitter Setup Note: Key descriptions can be found inside the Transmitter lid.
Direct Connect Method Make sure the Transmitter is off. Plug the direct connect cable into the front panel jack. Connect the Black clip to the ground rod. Place the ground rod in the earth perpendicular to the suspected cable path. If necessary, extend the black lead with the Ground Extension Cable. Remove the ground bonding and attach the Red clip to the shield.
Dyna Coupler Method Connect the Dyna-Coupler to the Transmitter front panel jack using the coupler cable. Clamp the Dyna-Coupler around the cable below any bonds just before the cable enters the earth. The jaws of the coupler must fully close. Press to apply Tracing signal and select the 33 kHz frequency. LED indicates frequency selection. (This key can also turn the unit on.) Select high output level by pressing .
Induction Method Place the transmitter on the ground over the target cable with the lid hinge in line with the cable path. Press to turn the transmitter on and select the 33 kHz frequency. LED indicates the frequency selection. For greater tracing range, select high output level by pressing . Transmitter setup is finished, now go to LOCATING A BURIED CABLE - Receiver Setup (PAGE 8).
LOCATING A BURIED CABLE Receiver Setup Note: Key descriptions can be found on the side of the Receiver. Press to turn the Receiver on. to select the 50/60 Hz power frequency (see section on Press Selecting Passive Power Frequencies Page 9) or LF for passive locating; otherwise, select the same frequency as the Transmitter. Note: The Receiver is automatically set to Special Peak mode when LF is selected. No other modes are allowed in LF frequency.
About Trace Modes Peak: In this mode, as the antenna crosses the cable, the Receiver speaker volume increases to a maximum and the bar graph fills from both sides toward the middle. As the antenna moves off the cable path, the speaker volume decreases and the bar graph opens. Peak with High-Expanded: While in Peak mode, press to select High-Expanded (the highest setting). Speaker response is cut off as the antenna moves away from the cable.
DETERMINING CABLE DEPTH AND CURRENT Place the Receiver Antenna on the ground directly above the cable with the handle parallel to the path. Press cable depth and relative current corner of the display. Press press and the display will indicate the . Current is displayed in the lower left twice to continue tracing. You may also to return to Trace mode. LOCATING AN ACTIVE DUCT PROBE (ADP) Press to turn the Receiver on. Press to select the 33 kHz frequency.
LOCATING EMS MARKERS EMS markers may be detected and located using either the 3M Dynatel™ 2205 or 2206 EMS Marker Locating Accessory. To attach the accessory, slide the Receiver horizontally into the EMS Marker Locating Accessory mounting slot. Make sure the locking button holds the Receiver securely in the slot. To separate the units, press the locking button down and slide the Receiver out of the EMS Marker Locating Accessory mounting slot.
CABLE OR PAIR IDENTIFICATION Transmitter Setup Transmitter setup is the same to identify cables or pairs. However, Receiver setups are different. Perform a battery test; then, connect the Dyna-Coupler to the Transmitter front panel jack using the coupler cable. Note: Cable Identification requires two Dyna-Couplers: one at the Transmitter and one at the Receiver. Clamp the Dyna-Coupler around either the cable or both tip and ring of a pair and make sure the jaws fully close.
PAIR IDENTIFICATION Receiver Setup Connect the inductive probe to the Receiver accessory jack using the probe cable. Press to turn the Receiver on. Press to select the 33 kHz frequency. Insert the Probe into the bundle of pairs (or the group, if known) and press . Next, divide the pairs into two bundles and insert the Probe into each of the bundles and observe the numeric display. The bundle with the highest reading will contain the target pair.
