1 Safety
This section provides an overview of the safety aspects that
must be observed when operating the instrument.
The instrument has been constructed in accordance with the
state of the art and it is operationally safe. It has been tested and
left the factory in perfect working conditions. The information
in this guide, as well as the applicable documentation and
certificates, must be observed and followed to maintain this
condition throughout the period of operation.
Full compliance with the general safety requirements must be
observed during operation of the device. In addition to the
general information, the individual sections in the manual
contain descriptions of processes or procedural instructions
with specific safety information.
Only by observing all of the safety information can you reduce
to the minimum the risk of hazards for personnel and/or
environment. These instructions are intended as an overview
and do not contain detailed information on all available models
or every conceivable event that may occur during setup,
operation, and maintenance work.
For additional information, or in the event of specific problems
not covered in detail by these operating instructions, please
contact the manufacturer. In addition, ABB declares that the

LLT100
Laser level transmitter
1.2 Personnel
WARNiNG
Only qualified and authorized specialists should be
charged with the installation, electrical connection,
commissioning, operation, and maintenance of LLT100
instruments.
These specialists must hold the necessary
qualifications, such as training or instruction,
to operate and maintain devices or systems in
accordance with safety engineering standards
regarding electrical circuits, high pressures, aggressive
media, and adequate safety systems, based on local
national standards such as NEC for USA, National
Building Code, etc.
Since the LLT100 may form part of a safety chain, we
recommend replacing the device immediately if any
defects are detected.
Only use non sparking tools when installing the
instrument in hazardous areas.
WARNiNG
The device can be operated at high levels of pressure
and with aggressive media. As a result, serious injury
or significant property damage may occur if this device
is operated incorrectly.
Any process media released may cause severe injuries.
Depressurize the pipeline/tank before opening the
LLT100 connection.
Provide adequate protection and training against
chemicals involved in the work environment.
Carefully plan any installation, modification, or repair
before actually proceeding.
1.3 Electrical
Electrical connections may only be established by authorized
specialist personnel in accordance with the electrical circuit
diagrams. The electrical connection information in the manual
must be observed; otherwise, the applicable protection
type may be affected. Ground the instrument according to
requirements.
In addition, you must observe the relevant safety regulations
regarding the installation and operation of electrical systems,
and the relevant standards, regulations and guidelines about
explosion protection.
WARNiNG
Avoid contact with leads and terminals. Electrical
shock could result in death or serious injuries.
Do NOT make electrical connections unless the
electrical code designation stamped on the LLT100
data plate matches the classification of the area in
which you want to install the LLT100. Failure to comply
with this warning can result in fire or explosion.
Use only tools compliant with national insulation
standards, like DIN EN 60900.
Only use non sparking tools when installing the
instrument in hazardous areas.
During installation, completely power down the
4–20mA loop for at least 60 seconds, as otherwise it
may cause a permanent error.
Figure 1 External protective earth (PE) terminal
1.3.1 Surge protector-equipped terminal block
To ensure proper functioning, ground connection is mandatory
for surge protector-equipped instruments.
CAutioN
Test voltage withstand capability can no longer be
ensured when this protective circuit is used.
1.3.2 Common mode voltages
The LLT100 with surge protection will not work if exposed to
common mode voltage in excess of the maximum allowed
supply voltage.
WARNiNG hiGh VoltAGE
Ensure that the equipment or any device or power cord
connected to the LLT100 is properly grounded.

OI-LLT100-EN Rev. D | User Guide 3
WARNiNG hiGh VoltAGE
All protective earthing connections (grounding) must
be active at all times. The absence of grounding can
lead to a potential shock hazard that could result
in serious personal injury. If an interruption of the
protective earthing connection is suspected, ensure
the equipment is not used.
Use the LLT100 ONLY if a properly grounded power
source is available in accordance with the local
electrical code.
Before using the LLT100, make sure that the
appropriate supply voltage is available.
WARNiNG pRopE Rt y DA mAGE
Depending on the model, there may be no EMC
protection or protection against accidental contact
when the housing cover is open. Therefore, the
auxiliary power must be switched off before opening
the housing cover.
NotiCE
The presence of noise on the instrument 4 – 20mA
output can be a sign of poor or intermittent grounding,
insufficient cable shielding, or noisy power line in the
vicinity.
1.4 Laser
lASER RADiAtioN
Invisible laser radiation at 905 nm.
Class 1 laser is safe for all conditions.
The LLT100 uses a Class 1 infrared (905 nm) laser producing
an invisible beam that is used to measure distance. A Class1
laser is safe under all normal operating conditions. This means
that the maximum permissible exposure (MPE) cannot be
exceeded when viewing a laser with the naked eye or with the
help of typical magnifying optics (e.g. telescope, microscope
magnifying glass, lenses of any type).
Invisible laser, Class 1 (standard operation)
Wavelength 905nm
Peak Power 45W
Average Power 7.1mW

Pulse Train Duration (total) 0.190ms
Beam Dimension at 30 m 20cm× 3cm
Divergence Δ < 0.3°
The LLT100 is designated as a Class 1 laser device during all
procedures of operation, as per IEC 60825-1, Ed. 2, 2007. It
complies with FDA performance standards for laser products,
except for deviations pursuant to Laser Notice No. 50, dated
June 24, 2007.
1.5 Improper use
It is prohibited to use the instrument for any, including but not
limited to, of the following:
– A climbing aid, e.g., for mounting purposes.
– A support for external loads, e.g., as a support for pipes.
– By adding material, e.g., by painting over the name plate, or
welding/soldering on parts.
– By removing material, e.g., by drilling the housing.
Repairs, alterations, and enhancements, or the installation of
replacement parts, are only permissible as far as these are
described in this manual. Approval by ABB must be requested
in writing for any activities beyond this scope. Repairs
performed by ABB-authorized centers are excluded from this
article.
1.6 Technical limit values
The instrument is designed for use exclusively within the
values stated on the name plates and within the technical limit
values specified on the data sheets.
Technical limit values that must be observed at all time are:
– The maximum working pressure, ambient working
temperature, and maximum process temperature may not
be exceeded.
– The housing protection type must be observed.
– The electrical specifications must be observed.
1.7 Operator liability
Prior to using corrosive and abrasive materials for measurement
purposes, the operator must check the level of resistance of
all instrument parts coming into contact with the materials to
be measured.
CAutioN
Prior to using the LLT100, material safety data sheets
(MSDS) of all products being monitored must be
available at all times for the security of the user.
ABB will gladly support you in selecting the materials, but
cannot accept any liability in doing so.
Operators must strictly observe the locally applicable national
regulations with regard to installation, function tests, repairs,
and maintenance of electrical devices.
