2.2 Unpacking and activating the C-Scan 2010 Detector Unit (DU)
2.2.1 Unpacking
For shipping safety the Detector Unit is shipped with its batteries packed separately.
Unpack the entire system from its yellow transportation case and make sure all the
items, including those stored in the lid of the Signal Generator, are present in
accordance with the packing list.
NOTES:
1. A spare copy of the packing list can be found in the plastic zip envelope containing the
manuals and other documents. Report any obvious damage or any missing items,
immediately.
2. To open the lid of the Signal Generator (SG) it may be necessary to push the red button
on the front face of the SG case to release internal vacuum.
3. Do NOT try to activate damaged equipment.
If everything appears to be present and undamaged proceed to 2.2.2 below.
2.2.2 Charging the Signal Generator (SG)
NOTES:
There are two battery chargers supplied with the equipment. They are identical and can be used
interchangeably to charge either the SG or the Detector Unit (DU).
The SG is powered by completely sealed lead-acid batteries. These batteries are permanently
installed and may be replaced only by a trained technician. External back-up power can be
supplied to the SG through its external port –for more information see part 2 –Survey Procedure
manual supplied as separate document.
Use one of the battery chargers and its power cord to charge the SG as follows:
•Remove the black charging port cover on the SG (located on the front face of the
casing). Unscrew (anti-clockwise) and plug-in the matching charger lead connector.
•Plug in the mains (Power) lead into a mains supply socket outlet (the charger is a
120-240VAC universal model with a 240VAC 3-pin Euro Plug provided). Make sure
the mains outlet is ‘live’. Note that the mains lead may need to be replaced –or the
plug changed –to suit other mains voltage supplied / outlet sockets.
•Press the SG ON button (located on the SG control panel). A series of messages
will appear in the SG’s LCD display which will stop at the message BATTERY A IS
BEING CHARGED. The computer-controlled charging program will cycle the
batteries, charging each in turn until they are close to being fully charged. At this
point the message will terminate and switch the unit off automatically.
NOTE; the batteries are shipped in a very low state of charge and it may thus take up to 60 hours
of continuous charging to reach a fully charged state. The unit should be left on charge until it

turns itself off. IMPORTANT: interrupting the initial charging cycle may seriously affect the ability
of the batteries ever to reach full capacity.
2.2.3 Charging the Detector Unit (DU)
NOTES:
The DU can be powered either by re-chargeable D–size NiCad batteries OR by D-size alkaline
batteries, both of which types are supplied with the unit. Only the NiCad batteries can be
charged using the following procedure. Using the charger with alkaline batteries installed in
the DU will result in damage to the unit.
There are three charging procedures:
(a) for charging NiCad batteries that are not completely exhausted (flat)
DU off.
(b) for charging NiCad batteries that are not completely exhausted (flat)
DU on.
(c) for charging completely exhausted (flat) NiCad batteries
The NiCad batteries are completely exhausted (flat) when the DU display
does not activate after the I/O button on the display panel is pressed with
the batteries installed.
There are two controls for the power supply to the DU:
1. The MAIN POWER switch (located in the battery
compartment and normally left ON –see Fig. 1 Right
2. For normal operational use the DU is switched ON and Off by pressing the button marked I/O
on the DU display panel / control keypad.
•DO NOT USE THE CHARGER WHEN ALKALINE BATTERIES ARE
INSTALLED IN THE DU –overheating and possible damage will occur!
•NEVER use carbon/zinc or lithium-based batteries AT ANY TIME!
•NEVER user or charge a mix of different types of batteries!
•Unpack the six (6) NiCad batteries and put them on one side. Locate the elongated
black plastic panel on the lower back spine (the battery compartment and main
power switch cover). Remove the panel using the large black knob. Now rermove
the two battery covers using a coin (twist 90° anticlockwise). Ensure the main power
switch in this compartment is OFF! Insert the batteries NEGATIVE (-ve) end first,
three to each battery compartment –see Fig. 2 on page 2-4 below.. Replace the
battery compartment covers (90° twist clockwise) and then switch the main power

switch to ON.
•The LCD will now display the clock and date setting panels –see Figs 3a & 3b
below -if there is sufficient residual charge left in the batteries. The 1st charging
procedure detailed in Steps 1 thru 3 below may now be followed.
NOTE: If the display does not activate, re-open the battery compartment and turn the
Main Switch to OFF again, wait for 5 seconds, then switch it back to ON. If the display
then activates, proceed with steps 1 thru 3 below.
NOTE: Subsequent removal/ replacement of the batteries will necessitate this same date/time
setting procedure because these batteries power the clock. Hence the clock settings are lost
every time the batteries are removed or replaced or the Main Power Switch in the battery
compartment is turned to ‘OFF’.
If the display still does not activate this indicates the NiCad batteries are exhausted and the 3rd
charging procedure detailed in Step 4 below must be followed. Proceed to 2nd charging
procedure below.

Note also that up to this point no buttons have been pushed on the DU display panel. The only
switch that has been activated is the Main Power Switch in the battery compartment.
WARNING! In all below procedures the mains switch must be on before the
charger is attached..
•1st charging procedure (for partially discharged NiCad batteries and DU switched
off)
Locate the battery charger port to (the black connector below the battery compartment
cover).
Unscrew the port cover and attach the battery charger to this port. Connect the charger
power cord to a mains outlet socket. Make sure the mains outlet is ‘live’.

This indicates a timer that counts backwards, the time displayed being the maximum
time allowed to charge the batteries. If the batteries are charged before that time has
expired (counted down to zero) charging will be terminated and the unit switched off
automatically.
If it is necessary to terminate the charging cycle before the batteries are fully charged
and the unit has turned itself off, the charging cycle may be ended by pressing the X
key.
Step 3 The charging process is a rapid cycle program and is automatic. It will
terminate when the batteries are fully charged. Once it is activated the automatic timer
provides adequate time for exhausted batteries to be fully charged. Hence it should
not be necessary to re-run the charging program once it has completed the process
automatically.
NOTE: attaching the charger whilst the unit is turned off at the I/O switch (but the Main Power
Switch must be ON) will automatically trickle-charge the batteries. IMPORTANT: if the unit is
switched on at the I/O button whilst the charger is attached, the unit will go into charge
mode automatically (1st charging procedure).
•3rd charging procedure (for completely exhausted NiCad batteries DU will not switch
on)
Step 4 Make sure the Main Power Switch in the battery compartment is ON
position. Connect the charger power cord to the mains supply outlet socket. Make sure
the socket is ‘live’. Leave the charger attached for a 30 minutes –applies to units
D/1669 or later. The charger will now charge the batteries. When the batteries have
been charged sufficiently the unit will automatically turn on and continue the charge
cycle. If unit fails to switch on, disconnect the charger, switch off (at switch) for 5
seconds, then on again –then proceed to 2nd charging procedure, step 1 above.
WARNING! In all above procedures the main switch must be ON before the
charger is attached..
NOTE: Attaching charger without batteries will start the detector in charge mode. Since
there are no batteries, they will not be charged. System will switch off in 4 hours or can
be aborted by pressing the X key.
If this has been done, disconnect the charger, switch the switch to OFF, insert batteries,
switch to ON. Then proceed to 2nd charging procedure, step 1 above.

General Guidance Notes on the batteries used in the C-SCAN System.
GGN 1 C-Scan Signal Generator (SG)
The power supply for the SG can be augmented by connecting an external 12 volt vehicle type
battery via the connecting cables (black and red leads with fuses and ‘crocodile’ clips) supplied
and stored in the lid of the SG casing.
The lead is plugged into the dual purpose charging/external power supply port on the front of the
SG casing and the red and black clips attached to the appropriate polarity post connectors of the
vehicle battery. When it is turned on, the SG will ‘recognize’ that external power is available and
will utilize this source until the battery loses its charge. If the external power source is exhausted,
the SG will automatically switch over to its internal batteries thus ensuring that no break occurs in
the survey process.
The batteries in the SG are of the completely sealed, non-spillable, lead-acid type. They must be
kept charged to ensure a long life. If the SG is to be inactive for any length of time –e.g in
excess of one month -it will be necessary to place the unit on a booster charge to maintain its
power level. To do this, attach the battery charger and press the I/O button to begin the charging
process. The unit will turn itself off when a full charge is accomplished.
The unit does not trickle-charge. It will be necessary to repeat the booster charging process more
than once if the unit is inactive for longer periods: every 30 days will be sufficient.
GGN 2 C-Scan Detector Unit (DU)
The Detector unit uses six (6) D-cell batteries. They can be rechargeable NiCaD or Alkaline
batteries. NEVER mix battery types. If the installed NiCad batteries run low in the field during a
survey, they can be changed in the field without affecting data already stored. The replacement
batteries can be of either type but all in the group of 6 must be of the SAME type.
Never attempt to re-charge Alkaline batteries in the DU or damage will result.
The DU draws a small amount of current from the batteries when it is switched off at the
Control/Display Panel I/O switch, but with the main power switch left ON. If left for a long period
in this state the power in the batteries eventually will be reduced to zero. If the unit is to be
inactive for a period of time, either remove the batteries completely OR switch the Main Power
Switch to Off. If the unit is to be shipped or stored it is recommended that the batteries be
removed for safety reasons.
Leaving Alkaline batteries in a stored DU -even with the Main Power Switch Off -may result in
battery corruption and leakage, causing internal damage to the DU.
Remember, if the batteries are removed and/or the Main Power Switch is turned Off for any

reason, the time and date will need to be reset when the DU is re-activated.
IMPORTANT FEATURE: Survey Data Storage is NOT affected by the removal of the batteries.
However, be sure to use reasonably fresh batteries when downloading data from the DU.

2.3.3 Search
In this example,
from the Search
screen display –
see Fig 13 right –
it can be seen that
the pipeline is
located behind
and to the right of
the current
position of the
Detector Unit (DU)
–see Fig, 12 left.
As the DU is turned so the indicator in the centre of the screen will rotate.
NOTE: the circle equals a 2 metres (approx. 6ft 6”) distance. If the pipeline is greater
than 2 metres away then the line will stay in the boundary. The number above the circle
indicates the horizontal distance in metres (1.2m in this example). If the pipeline is out
of range no figure will be displayed.
It is not possible to give accurate figures when the DU is not directly over the pipeline, so all
numbers shown are approximate (indicated by the ~ symbol).
In this example depth to the centre is 1.3m To change this to depth of cover, press the
key adjacent to the cover symbol (bottom LH corner box). Note that if the pipeline
diameter has not been entered, this symbol will not be shown.
The GPS position indication is showing a ‘BAD’ signal –i.e: no satellites in view.
NOTE: if the GPS has just been powered up, this ‘BAD’ signal will be displayed.
Acquisition times vary from 10 secs to 45 mins. If the DU has been moved a large
distance –or this is the first time that the DU has been used –the acquisition time will
be likely to be nearer to 45 mins. It is important that the DU (with GPS ON) is switched
on for at least 15 minutes after a position is displayed; this will ensure a fast turn-on
next time. After acquisition, the display will show ‘GOOD’ plus the number of satellites
available.

The CALCULATION key takes a large sample and converts the approximate readings
into accurate data.
NOTE: it is important that the DU is held stationary and perpendicular to the pipeline
after the CALCULATION key is pressed. Any movement will upset the readings and
result in data errors.
The CLOSE key is for CLOSE INTERVAL CURRENT SURVEY. This is discussed in
Section 4.8 later in this manual.
Keep the instrument still and press the CALCULATION key now.
