DANGER!
WILL CAUSE DEATH
Failure to follow this warning will result in death or serious injury to personnel.
WARNING!
DANGER TO PERSONNEL
Failure to follow this warning may result in serious injury to personnel.
CAUTION!
MAY CAUSE DAMAGE TO EQUIPMENT
Failure to follow this warning may result in damage to the equipment.
NOTICE
Important or tip messages will appear in this format.
Safety Information
All authorized users, including installation, operation, and maintenance personnel, must observe the following safety precautions
and warnings.
DANGER!
ELECTRIC SHOCK
The detector operates using mains voltage that is dangerous to life. Make sure that the circuit breakers are set to OFF and tagged off
before removing the top cover or opening the front cover.
Failure to observe this precaution will cause death, personal injury, and/or damage to persons and/or property.
WARNING!
OPTICAL RADIATION EXPOSURE HAZARD
The detector contains lasers. Opening the detector and attempting to perfrom adustments and procedures other than those
specified in this manual may result in hazardous optical radiation exposure.
All lasers within the detector are Class 1. The emitted laser light is invisible (mid-infrared) and the combined laser powers are
sufficiently low at the first accessible aperture that the unprotected eye will not be damaged. This class is eye safe under all
operating conditions.
It is, however, possible to cause damage to the eye through not following correct procedures. Do not look at the laser with any kind
of magnifier or optical measuring device.
WARNING!
HAZARDOUS SUBSTANCES
The detector may contain hazardous substances. Always handle the detector assemblies and components with extreme caution.
Gas handling components within the detector will contain particulate matter from the sample gases. Over the life of the detector,
the concentration of particulate matter will become enriched within the gas handling components. When performing repairs and
maintenance on the detector:
• Handle used gas handling components with extreme caution.
• Avoid direct skin contact with used gas handling components.
• Do not smoke, drink, or eat in the work area.
• Wear goggles or eye shields.
• Wear a suitable face mask to protect against inhalation of particulate matter.
• Do not wet fingers, eyes, or any exposed skin.
• Pack used gas handling components for disposal in sealed packaging and label them Contaminated.
Dispose of contaminated items as hazardous material according to the applicable local, national, or international health and safety
regulations and pollution regulations.
WARNING!
EXPLOSION HAZARD
Always lock-out tag-out the gas handling system when shutting down the detector. Unauthorized operation of the gas handling
system when maintenance is being performed on the detector or its associated pipes/hoses may result in highly flammable gas
being released, causing fire or explosion.
WARNING!
HIGH PRESSURE GAS AND AIR
The compressed air supply operates at a pressure that can cause injury, e.g., damage to eyes and skin punctures from debris blown
by the high pressure gas or compressed air.
Always lock off or tag off the calibration gas supply and compressed air supply when shutting down the detector.
WARNING!
EXPLOSION HAZARD
The sample gas in the system must be vented to prevent fire or explosion during maintenance and to prevent damage to the
detector during startup.
The sample gas in the pipes leading to the detector must be purged to prevent hazards to personnel during maintenance. Purge the
sample gas in accordance with the safe working procedures for the site.
Allow the detector and system for returning the sample gas to run for five minutes to allow any sample gas in the system to be
returned to the exhaust.
WARNING!
HEAVY INSTRUMENT
The detector weighs 119 kg (268 lb.) and is designed to be floor mounted. It must be moved in accordance with local safety
regulations. EmersonTM recommends that a minimum of two people using suitable tools for transportation and lifting are employed.
Use suitable fasteners for the weight of the unit.
Make sure the unit is mounted on a solid, stable, and suitable floor.
Failure to follow this warning could cause an explosion or potentially hazardous situation, which if not avoided, could result in death
or serious injury.
WARNING!
ELECTRICAL SHOCK HAZARD
Only trained, qualified personnel may install and connect power and signal cables. The installation/connection must be in
accordance with all legislative requirements and applicable standards.
Only qualified personnel, familiar with the resulting potential risks, should install these instruments.
Instruments providing screw terminals for electric connections may require working near live parts.
Failure to follow this warning could cause an explosion or potentially hazardous situation, which if not avoided, could result in
warranty invalidation, property damage, death, or serious injury.
WARNING!
HIGH PRESSURE HAZARD
The maximum compressed air pressure at the inlet valve must not exceed 10 bar (145 psi). Failure to follow this warning could cause
a potentially hazardous situation,which if not avoided, could result in death or serious injury.
WARNING!
LOOSE ITEMS
Do not place any loose items on top of the system or inside the compartments when doors or covers are open.
Make sure that all loose items, tools, and equipment are removed from the compartments before closing doors and covers.
Failure to follow this warning could cause a potentially hazardous situation, which if not avoided, could result in death or serious
injury.
WARNING!
On completion of any maintenance and/or modifications, make sure:
• All tools and equipment are removed.
• No contamination (water/dust) is in the compartments.
• The detector is wiped clean.
• Vents are clear and not obstructed.
• The system is in a safe state for operation.
Failure to follow this warning could cause a potentially hazardous situation, which if not avoided, could result in death or serious
injury.
WARNING!
TRANSPORTATION HAZARD
Use safety approved lifting equipment. Ensure that the equipment is tested, meets the lifting ratings for the weight of the
equipment, and is in good operational condition. Failure to verify that equipment meets the lifting ratings and is in good operational
condition may injure personnel or damage the detector.
CAUTION!
EQUIPMENT DAMAGE
Always follow the startup procedure. Damage to the detector may result from a failure to follow this procedure.
Failure to perform pre-system startup checks may cause damage to equipment.
CAUTION!
EQUIPMENT DAMAGE
Always follow the shutdown procedure. Damage to the detector may result from a failure to follow this procedure.
CAUTION!
EQUIPMENT DAMAGE
Ensure that the local power voltage where the unit is to be installed corresponds to the unit’s nominal voltage as given on the name
plate label.
NOTICE
As a general principle, if any optical component other than the cell assembly, the laser modules, and the detectors is unserviceable,
EmersonTM must repair the detector. This is because the repair, replacement, and alignment of the optical components requires the use of
special optical testcalibration equipment and procedures. When an item is unserviceable, and no replacement procedure is given in this
manual, EmersonTM must repair the fault.
Symbols displayed on and inside the detector
To minimize risk, labels displaying warning signs are fixed to the transmitter. You must
understand their meaning, take suitable precautions, and read all instructions given in the
accompanying manuals before conducting any operations.
The following table gives examples and definitions of each symbol used.

ii Rosemount CT4215
1 Leak detection overview
Gas concentrations are measured using mid-infrared optica absorption spectroscopy. The
light sources are Quantum Cascade Lasers (QCLs), which are operated to produce
wavelength sweeps that cover the absorption lines of the target gases.
The laser is mounted in the baseplate between the upper and lower enclosures of the leak
detector, and light is directed through the measurement cell and onto a detector. When
molecules from a leaking container enter the measurement cell, they partially absorb the
laser light. The variation in the intensity of the light indicates a leaking container, and the
container is rejected from the line.
The leak detector identifies packaged products that have a break in seal integrity as they
are carried along a conveyor belt at speed. The leak detection system consists of a
sampling head which draws air from around the product. The air is passed through the
measurement cell for high speed analysis.
