1. GENERAL DESCRIPTION
The 3007 Electromagnetic transmitter is a high-power unit which is used for pig tracking and
locating either subsea or topside.
The transmitter operates effectively in buried pipelines, pipelines carrying gas, and in pipeline
bundles where acoustic transmitters are either less effective or ineffective.
The transmitter emits a 22Hz signal and an inherent EM null spot is detectable when the
antenna is at 90 degrees to, and pointing at the centre of, the transmitter allowing accurate
positioning of a pig.
The standard transmitter can be changed between two pulsing transmission rates via an
external rotating switch.
Parameters such as lifetime, pulse mode and battery type can be customised at the customers’
request, please contact Online Electronics Ltd to discuss any special requirements.
DELAY ACTIVATION OPTION: The 3007 has a configurable time delay which commences
when the unit is switched on, after the time delay has expired the unit will activate.

3. OPERATION
NOTE 1 - DO NOT EXPOSE TO AGGRESSIVE SOLVENTS OR CHEMICALS WHICH COULD
BE HARMFUL TO THE HOUSING, ENDCAPS, OR NITRILE RUBBER O-RINGS.
NOTE 2 - OPENING OF THE UNIT SHOULD ONLY TAKE PLACE IN A CLEAN, DRY,
LABORATORY ENVIRONMENT.
NOTE 3 - TO PREVENT THE FORMATION OF CONDENSATION WITHIN THE UNIT
ALLOW THE UNIT TO STABILISE WITHIN THE LABORATORY ENVIRONMENT FOR A
MINIMUM OF 6 HOURS PRIOR TO OPENING.
NOTE 4 –IF THE TRANSMITTER IS BEING OPENED FOR THE FIRST TIME AFTER
IMMERSION IN PIPELINE PRODUCTS THEN EXPECT SOME LIQUID TO BE PRESENT
WITHIN THE ENDCAP THREADS. CARE SHOULD BE TAKEN WHEN OPENING THE UNIT
TO ALLOW ANY LIQUID TO DRAIN OUT OF AND NOT IN TO THE TRANSMITTER.
NOTE 5 - ALWAYS LOOSEN THE BLEEDSCREW TO RELIEVE ANY INTERNAL PRESSURE
PRIOR TO OPENING.
3.1. TURNING ON AND OFF
1. To turn the transmitter ON rotate the large white plastic disc on the
top of the switch endcap to either RATE 1 or RATE 2 using the
activation key. The transmitter will begin transmitting in the mode
selected.
2. Use an EM receiver to confirm that the transmitter is functioning
properly at the expected pulse rate.
3. To turn the transmitter OFF rotate the plastic disc on the top of the switch endcap to either
of the OFF positions using the activation key.
4. Use an EM receiver to confirm that the transmitter has turned OFF and stopped
transmitting.
3.2. FUNCTION TEST
An OEL EM receiver system is required to receive the signal from a 3007 EM transmitter.
1. Ensure that the bleedscrew on the rear of the transmitter is fully engaged, do not over
tighten.
2. Place the 3007 transmitter approximately 10m away and parallel to the antenna.
3. Activate the transmitter as detailed in section 3.1 TURNING ON AND OFF.
4. Switch the transmitter between OFF, RATE 1 mode, and RATE 2 mode several times and
ensure that the EM signal received reacts as expected. Refer to section 3.1 TURNING ON
AND OFF for further information on changing transmission rates.
5. An inherent EM null spot is detectable when the antenna is at 90 degrees to and pointing
at the centre of the transmitter allowing accurate positioning of a pig. Refer to the relevant
EM receiver manual for more information.
6. Turn OFF the transmitter as detailed in section 3.1 TURNING ON AND OFF.
7. System operation has been verified.

3.3. PIG INSTALLATION
The transmitter can be installed within the body of a pig or ideally towed using a flange and
support disc arrangement. Steels and other metals absorb electromagnetic signals so for
optimum signal strength the transmitter should overlap the pig body by as much as possible,
typically at least 150mm. Any apertures which can be made in the pig body around the
transmitter will be advantageous.
1. Ensure that the bleedscrew on the rear of the transmitter is fully engaged, do not over
tighten.
2. Place the transmitter within the cavity of the PIG in a position which allows access to the
switch endcap so the transmitter can be turned ON. Ensure that it is secure and cannot
move around.
3. Use wedging blocks of PU if required to prevent movement and vibration.
3.4. DEPLOYMENT
The following section does not provide a comprehensive deployment procedure as every
deployment is different. It does however outline the most important considerations when
deploying an EM transmitter and should be read and understood well in advance of
deployment.
1. At least 24 hours prior to deployment any personnel who will be involved with the
operation of the transmitter should review this entire manual to familiarise themselves
with the unit. They should also be allowed time to operate the unit and EM receiver.
Simply allowing personnel to ‘play’ with the equipment before it is actually deployed can
save significant costs compared to deploying the unit without understanding how it works
and then suffering from an unnecessary operator error.
2. Refer to Page 1 of this manual for the expected battery lifetime and ensure it is adequate
for the planned duration of operations.
3. Ensure that the bleedscrew on the rear of the unit is fully engaged, do not over tighten.
4. Activate the 3007 transmitter, refer to section 3.1 TURNING ON AND OFF for more
information.
5. Using an OEL EM receiver system, confirm that the expected EM signal is received from
the transmitter.
6. System operation has been verified and deployment can proceed.
3.5. TIME DELAY
Refer to Page 1 of the manual for the configured delay. If the transmitter has been configured
with a delay, then immediately after switching ON it will transmit a continuous signal for 10
seconds to allow confirmation of operation before entering a low power state. The transmitter
will remain in this low power state until the configured delay has expired and then it will start
transmitting as normal at the selected transmission rate.
To reset the transmitter and delay, the transmitter must be turned OFF for at least 30
seconds. While in the low power state, the expected lifetime will be reduced by approximately
1% each month. For example, after 50 months, 50% of the expected battery lifetime should
be achieved.

4. MAINTENANCE
NOTE 1 - DO NOT EXPOSE TO AGGRESSIVE SOLVENTS OR CHEMICALS WHICH COULD
BE HARMFUL TO THE HOUSING, ENDCAPS, OR NITRILE RUBBER O-RINGS.
NOTE 2 - OPENING OF THE UNIT SHOULD ONLY TAKE PLACE IN A CLEAN, DRY,
LABORATORY ENVIRONMENT.
NOTE 3 - TO PREVENT THE FORMATION OF CONDENSATION WITHIN THE UNIT
ALLOW THE UNIT TO STABILISE WITHIN THE LABORATORY ENVIRONMENT FOR A
MINIMUM OF 6 HOURS PRIOR TO OPENING.
NOTE 4 –IF THE TRANSMITTER IS BEING OPENED FOR THE FIRST TIME AFTER
IMMERSION IN PIPELINE PRODUCTS THEN EXPECT SOME LIQUID TO BE PRESENT
WITHIN THE ENDCAP THREADS. CARE SHOULD BE TAKEN WHEN OPENING THE UNIT
TO ALLOW ANY LIQUID TO DRAIN OUT OF AND NOT IN TO THE TRANSMITTER.
NOTE 5 - ALWAYS LOOSEN THE BLEEDSCREW TO RELIEVE ANY INTERNAL PRESSURE
PRIOR TO OPENING.
4.1. BATTERY PACK REPLACEMENT
Online Electronics recommends installing a new battery pack before each deployment to
ensure maximum contingency lifetime, to replace the batteries follow the procedure below. The
switch endcap holds the electronics and should only be removed under the direction of Online
Electronics or as part of an approved servicing schedule.
1. Carefully and slowly loosen the bleed screw to enable any pressure within the battery
housing to escape freely.
2. Remove the M8 retaining cap screws from the battery endcap, remove the endcap and
ensure that the Oring seals are protected from damage and contamination while the unit is
open.
3. Remove the plastic battery retaining plate which is secured with 2xM6 lock nuts. Identify
the battery connector and observe how the battery connection is routed inside the
transmitter.
4. Replace the battery pack and route the connections as observed previously (the connector
should be tucked neatly down the side of the battery pack to enable easy fitting of the
battery plate)
5. Examine the Oring seals for any signs of damage or contamination. Replace and/or
lubricate with silicone grease if necessary.
6. Reassemble the unit following the above instructions in reverse.
7. Refit the bleedscrew.
