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.
