WARNiNG
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
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

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).

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
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.
