Introduction PDL-4 Receiver
The PDL-4 is a portable receiver used for locating and identifying underground cables.
The Global Positioning System (GPS) fitted to the receiver enables the position of cables to be accurately logged and mapped.
When used with the following equipment the PDL-4 will positively identify a cable that emits an A.C.ID-M (Absolute Current Identification-Multi) signal.
§ VectorBar
§ Extended Range VectorBar
§ VectorBar 20
§ SmartProbe-2
§ Extended Range SmartProbe-2
§ LMS-3 or PTx-3 transmitter
The A.C.ID-M signal is described in the LMS-3 Manual.
Refer to the LMS-3 Manual and PTx-3 User Guides for transmitter operating instructions.
VectorBar
When placed on the ground over the target cable, and activated, the VectorBar receives the applied A.C.ID-M signal and relays A.C.ID-M status information to the PDL-4 via a short-wave radio link.
Extended Range VectorBar
The extended range VectorBar is tripod mounted and is used to locate cables that are buried too deep to be located by the standard VectorBar. Once assembled the extended range VectorBar operates in the same way as the standard VectorBar.
VectorBar 20
The VectorBar 20 is used to locate cables that are buried too deep to be located by the standard VectorBar. The VectorBar 20 incorporates an extendable arm to enable cables that have been laid at a greater depth to be located. The VectorBar 20 can be used with the arm fully stowed or fully extended. The VectorBar 20 operates in the same way as the standard VectorBar.
Page 1
PDL-4 A.C.ID-M System (with GPS) User Guide
SmartProbe-2
When pushed into the ground in close proximity to the target cable, and activated, the SmartProbe-2 receives the applied A.C.ID-M signal and relays A.C.ID-M status information to the PDL-4 via a short­wave radio link.
Extended Range SmartProbe-2
The extended range SmartProbe-2 is used to locate cables that are buried too deep to be located by the standard SmartProbe-2. The extended range SmartProbe-2 operates in the same way as the standard SmartProbe-2 except for an LED (Light Emitting Diode) that illuminates when the unit is activated.

Menu keys
Pressing a Menu key accesses the Cable Locate Control menu (Perform CD Reset, Confirmation, Log Data options).
Note: When using some frequencies not all of the above options may be available.
Gain Control Paddle
If the signal strength is at maximum or less than 10%, a momentary flick of the control in the appropriate direction will cause the gain to be adjusted to give an approximate bar graph indication of 50%. If the signal strength is below maximum and greater than 10%, the control will adjust the gain in 1dB steps with each momentary flick or by rapid stepping if the control is held when rotated.
Page 3
PDL-4 A.C.ID-M System (with GPS) User Guide
In Direct Selection mode, and when using other screens requiring selection from a list, rotate the Gain Control to move the highlight bar up or down. Rotate the gain control to adjust the contrast when the Contrast screen is displayed.
Speaker Sounds
The volume is controllable in four steps: Off, Low, Medium and High, via the menu system.
PDL-4 The speaker sounds are as follows:
1. At switch-on, the speaker will generate a continuous tone for 1 second, at the volume setting last used. If the volume is set to Off, the tone will still be generated, but at the lowest audible level.
2. Whenever a key is pressed, the speaker will generate a confirmation "beep". If the key has a secondary "press and hold" function a higher tone beep will also be generated as soon as the secondary function is initiated.
3. When locating a cable in Null (Left/Right) mode, the speaker will generate a pulsing tone when the cable is to the left of the PDL-4, and a continuous tone when the cable is to the right.
4. When locating a cable in Peak mode, the speaker volume will increase as the cable is neared.
5.When locating a cable in Power mode, the speaker will generate "Signal Sound" - derived from the signal detected, at amplitude proportional to the signal amplitude.
6.Whenever the PDL-4 detects an error condition during a self-test, or at any other time, the speaker will generate the standard low­frequency "Error" tone. This will be a short "beep" if a non-functional key is pressed, or will be for 2 seconds if an error condition is detected.
7.Whenever it is necessary to alert the user, the speaker will generate the standard "Alert" tone. This will be a repeating cycle of 5 rapid "beeps" followed by a four-second pause. The Alert tone will always be generated at the highest audible level, regardless of the speaker volume setting.
Page 4
PDL-4 A.C.ID-M System (with GPS) User Guide
Conditions resulting in the Alert tone include:
a) The battery becoming almost
exhausted
b) The Inactivity Timer expiring.
When the volume is set to Off, the speaker will still generate key press confirmation "beeps" and the "Error" tone - but at the lowest audible level. When the unit is first switched on, it will select the volume setting last used.
GPS
• When the location and GPS data have been acquired and logged, the sounder will generate a single confirmation “beep”.

Note: Do not move or touch the VectorBar while it is
calculating.
The VectorBar can be deactivated by pressing and holding the green button, until the LED extinguishes.
When the green button is pressed on the VectorBar the PDL-4 will automatically switch to VectorBar mode and display the following information:
VectorBar software version. VectorBar battery condition. Tilt angle of bar. 'Waiting for Data'. 'Checking A.C.ID-Mx' progress bar (where x is the customer unique code) GPS icon.
After approximately 20 seconds (depending on signal strength), the VectorBar will normally transmit initial location data to the PDL-4.
If a GPS position has been fixed the GPS icon will extinguish.
A 'Checking A.C.ID-Mx' progress bar is displayed and as each intermediate result is received from the VectorBar, the PDL-4 increments the Intermediate Result number by one.
The dotted area represents the region within which the cable has been detected. The size of this area indicates the accuracy achieved by this stage of the measurement cycle.
A number of "Intermediate Result" screens may be displayed (at intervals of up to 16 seconds) before the Final Result is displayed. The sequence of Intermediate Result screens may show increasing accuracy (i.e., the size of the dotted region may reduce with each Intermediate Result). It is also possible that the accuracy may not improve with each Intermediate Result, or could even deteriorate, e.g. due to a passing vehicle.
If the VectorBar reports an error, “Error” and a number are displayed on the wake-up screen. The numbers and corresponding errors are:
16 Invalid Software Version 32 Invalid Checksum
48 Invalid Calibration
In case of one of these error codes being displayed, contact your local Radiodetection office. The PDL-4 will report "A.C.ID-M Current not yet detected" if the VectorBar does not detect the
Page 16
PDL-4 A.C.ID-M System (with GPS) User Guide
A.C.ID-M signal, and the VectorBar will continue looking.
If the VectorBar is tilted, but by less than 450, the Intermediate Result screen is displayed. If the VectorBar has not been placed above the target cable the 'Reposition the VectorBar' screen will be displayed indicating the distance and direction that the VectorBar must be moved.
If the VectorBar has been placed too far away from the target cable the “Cable out of range” screen will be displayed indicating direction and approximate position of the cable.
If the VectorBar is not correctly aligned at 900 to the target cable a Plan View screen is displayed indicating the direction in which the VectorBar If A.C.ID-M confirmation is not achieved the PDL-4 will display 'Not Confirmed'.
When the A.C.ID-M data has been processed the 'CONFIRMED' screen, possibly the first of several will be displayed. The dotted box represents the region within which the cable is confirmed - the size of the box indicates the accuracy achieved.
Indicates A.C.ID-M Confirmation.
A number of Confirmation screens may be displayed (at intervals of up to 16 seconds) before the Final Result is displayed. The sequence of Confirmation screens may show increasing accuracy (i.e. the size of the box may reduce with each Confirmation Result). The Final Result is displayed either when the confirmation box is 6" wide (accuracy +/-3") or the VectorBar times-out after 5 minutes.
If a GPS position fix has been obtained "GPS OK" will be displayed in the bottom left-hand side of the screen.
If "no GPS" is displayed the locator is still obtaining a GPS position fix. Once the fix has been obtained, "GPS OK" is displayed. When GPS data is not immediately available and the confirm signal from the VectorBar has been received the display will show "Searching for GPS". After a 10 second delay the display will show "Searching for GPS. Press 'EXIT' to log without GPS".
Page 17
PDL-4 A.C.ID-M System (with GPS) User Guide
If the EXIT button is pressed depth and current will be logged without GPS data.
If the VectorBar is tilted at an angle of more than 45 the 'Tilt angle too great (450 maximum)' screen is displayed.
Successful confirmation cannot be achieved until the tilt angle is reduced to less than 450.
If the VectorBar is tilted, but at an angle of less than 450 the Confirmation screens will be similar to that shown opposite, which shows a Final Confirmation, achieved with A.C.ID-M.

If "no GPS" is displayed the locator is still obtaining a GPS position fix. Once the fix has been obtained, "GPS OK" is displayed.
When GPS data is not immediately available and the confirm signal from the SmartProbe 2 has been received the display will show "Searching for GPS". After a 10 second delay the display will show "Searching for GPS. Press 'EXIT' to log without GPS". If the EXIT button is pressed, depth and current will be logged without GPS data.

GPS User Guidelines
Buildings, foliage, and people can block signals from GPS positioning satellites. The ideal location using GPS is a wide-open space, with an unobstructed view of the sky in all directions. Make sure the unit has an unobstructed view of the sky before trying to obtain a fix.
Trying to obtain GPS readings in poor coverage areas may result in longer fix times and reduced PDL-4 battery life. To maintain battery life when locating in an inner city area, or any other area where poor coverage is to be expected, always select the GPS OFF option from the user preferences menu.
Do not leave the unit idling (waiting for a fix to be displayed) in the Display Fix mode for more than two minutes, as this will drain the battery.
Because GPS positioning satellites orbit the globe the actual number available for position fixing varies during the day. Long term testing has shown that occasional signal dropouts can occur where no coverage is available, regardless of location. As satellites appear over the horizon at least every 30 minutes, it is worth trying to obtain a position fix in difficult GPS locations at different times of the day.
The following guidelines will help in establishing consistent PDL-4 GPS performance.
• Avoid having people crowd around the GPS antenna during a fix.
• Hold the unit away from the body with the face of the GPS antenna flat to the sky.
• Keep the receiver stationary during a fix, as even slight movements will affect the signal levels from the
satellites reaching the antenna.
• Poor or non-existent coverage is to be expected when locating in built-up inner city locations.
• Keep cell telephones, hand held radios and laptop computers away from the GPS antenna during use.
• If the receiver is transported several hundred miles or more it will require a manual cold start command to
re-acquire its new position; this may take several minutes.
• The cold start key can be used to reset the GPS receiver at any time, but frequent use is to be avoided as fix times are extended and battery life reduced.
• PDL-4 GPS performance is comparable with commercial hand held units, but varying satellite patterns in the sky will favour different types of GPS antenna so direct comparison may be misleading.
The GPS performance is not affected by cloud cover, rain, or temperature. The GPS will not work indoors.
