1. GENERAL DESCRIPTION

The 3014X Electromagnetic transmitter is an ATEX certified EM transmitter that can be used
for pig tracking and location functions. 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 21.8Hz signal and an inherent EM null spot is detectable when the EM
receiver antenna is at 90 degrees to and pointing at the centre of the transmitter allowing
centimetre accurate positioning of a pig.

The transmitter can be changed between two pulsing transmission rates via an easily
accessible slide switch inside the transmitter.

The transmitter is configured for use with Lithium batteries only. Lithium batteries provide a
significant improvement in battery lifetime and operation particularly at temperature extremes.

A non-ATEX version of the transmitter can be manufactured with specially designed endcaps
which allow fitting of pigging discs directly to the transmitter - the transmitter itself becomes
the pig body. This dramatically increases the received EM signal because it no longer needs to
propagate through an additional pig body as well as the pipeline.

Parameters such as lifetime, pulse rate, frequency, and output level can be customised during
manufacture, please contact Online Electronics Ltd for more details.

3. OPERATION

THE SPECIAL CONDITIONS FOR SAFE USE DETAILED IN SECTION 7 APPENDIX A –
ATEX SPECIFIC INSTRUCTIONS OF THIS MANUAL MUST BE OBSERVED AND
FOLLOWED AT ALL TIMES

WARNING 1 – THE TRANSMITTER SHOULD ONLY BE OPENED IN A CLEAN, DRY,
LABORATORY ENVIRONMENT.

WARNING 2 – TO PREVENT THE FORMATION OF CONDENSATION WITHIN THE
TRANSMITTER ALLOW THE TRANSMITTER TEMPERATURE TO STABILISE WITHIN THE
LABORATORY ENVIRONMENT FOR A MINIMUM OF 6 HOURS PRIOR TO OPENING.

WARNING 3 – 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.

WARNING 4 – REPLACE ALL BATTERIES AT THE SAME TIME. NEVER USE A MIX OF
NEW AND USED BATTERIES. NEVER USE A MIX OF BATTERIES FROM DIFFERENT
BATCHES. USE ONLY ELECTROCHEM 3B0035-TC LITHIUM D CELLS. ALWAYS OBSERVE
CORRECT BATTERY POLARITY AND USE OF THE BATTERY DISC. REFER TO SECTION

3.9 LITHIUM BATTERY SAFETY FOR FURTHER INFORMATION.

WARNING 5 – IF THE TRANSMITTER IS TO BE PLACED IN STORAGE ALWAYS ENSURE
THAT IT IS TURNED OFF AND THE BATTERIES REMOVED AND STORED SEPARATELY.

3.1. TURNING ON

1. Familiarise yourself with all warnings given at the start of Section 3 OPERATION.

2. To turn the transmitter on, fully tighten the bleed screw using a 10mm AF Allen key. Do

not use excessive torque. The transmitter takes approximately 5 seconds to turn on. Note
that the transmitter is usually shipped with a Nylon washer under the bleed screw to
prevent accidental activation during transport. This must be removed before the
transmitter can be turned on.

3. Use an EM receiver system to confirm that the transmitter is functioning properly at the

expected pulse rate.

3.2. TURNING OFF

1. Familiarise yourself with all warnings given at the start of Section 3 OPERATION.

2. To turn the transmitter off, loosen the bleed screw 3 full turns using a 10mm AF Allen key.

To prevent the bleed screw being lost, or the transmitter accidentally being turned back
on, the bleed screw should be held in this position with some tape.

3. Use an EM receiver system to confirm that the transmitter has turned off.
