2.2 Proper Use - Conditions of Use
Operation
The LT3 Lambda Transmitter is an all-purpose O2 measuring device based on microprocessor
for direct measurement of the O2 concentration under super-stoichiometric range (λ > 1) used
together with Lambda Probe LS2
Operation
The Lambda Transmitter is an electronic data interpreting device which is used in conjunction
with the Lambda Probe LS2for the continuous measurement of the O2 concentration in non-
combustible gases in the superstoichiometric area.
Prerequisites
It is assumed that plant planning, mounting, installation, commissioning, maintenance, and
service work will be carried out by sufficiently trained personnel and that this work will be
checked by responsible skilled personnel. It must be particularly noted that
• the operation complies with the technical data and specifications regarding permissible
use, mounting, connection, and environment and operating conditions (refer to the con-
tract documents, the device user information, rating plates, etc.).
• work will be carried out in accordance with the local, plant-specific circumstances and with
regard to the operational risks and directives.
• all the measures required to preserve the value, e.g. for transportation and storage as well
as maintenance and service, are maintained.
Intended use
The product described here has left the factory in a flawless, safe and checked condition and
it must be maintained exclusively in the manner that is described by the manufacturer. Equally,
the proper transportation, correct storage and setup as well as the careful operation and main-
tenance, are critical for the flawless and safe operation of the device. Sufficiently qualified per-
sonnel must be used to install and operate this product. They must be familiar with the security
advice and warnings specified here and ensure they can be implemented flawlessly. Unqual-
ified persons working on the device or the warning information provided here or on the device
not being observed could result in serious personal injury and / or damage to property. The
device is being used as intended if the device is being used solely for the application specified
in the technical description. Auxiliary devices or those from other manufacturers must be rec-
ommended or authorised by LAMTEC. Provided the safety information and operating direc-
tives specified in this manual are observed, this device should not present any risks in terms
of damage to property or the health of personnel.

2.3 Permissible Users
Qualified personnel
The person responsible for safety absolutely must guarantee that
• only qualified personnel perform work on the system parts.
Due to their training, education, experience, or instruction and due to their knowledge of
pertinent standards, provisions, accident prevention regulations, and system conditions,
qualified personnel are authorized to perform these tasks by the person responsible for
the safety of people and the system. It is decisive that this personnel must be able to rec-
ognise and prevent risks on time.
Experts are considered to be people according to DIN VDE 0105 or IEC 364 or directly
comparable standards like DIN 0832.
• These persons must have access to the provided operating manual and any pertinent or-
der-related documentation during all work and observe these documents within the scope
of preventing risks and damage.
User groups
For the handling of the Lambda Transmitter LT3, three user groups are required:
• Service technicians of LAMTEC or its OEM customers and/or trained customer personnel:
– Qualified technicians/engineers  have very good knowledge of the device.
– SERVICE access level - password-protected
• Operators, customer fitters, technicians for instrumentation and control technology, elec-
tricians, and electronic engineers  have introductory knowledge of the device.
– CUSTOMER access level - password-protected
• Operating personnel with basic knowledge
– OPERATION access level - no password

2.4 Safety Equipment/Safety Measures
Hazards from electrical equipment
The LT3 Lambda Transmitter and the Lambda Probe LS2 is equipment for use in industrial
electrical power installations. Always switch off the power when working on mains connections
or mains voltage. If shrouding (for electrical safety) has been removed, reattach it before
switching on the power supply again. Damage to health or equipment may result from improp-
er use or improper handling.
NOTICE
To avoid damage, always observe the respective security notices.
Preventive measures for improving operating safety
If the LT3 is used in conjunction with control and monitoring technology, the operator must en-
sure that any breakdown or failure of the LT3 device does not cause inadmissible damage or
dangerous operating states. To avoid faults which could cause direct or indirect personal or
material damage, the operator must ensure that:
• the responsible maintenance personnel can be reached at any time and as quickly as pos-
sible
• the maintenance personnel are trained to correctly respond to faults with the LT3 Lambda
Transmitter and the associated malfunctions
• in the case of doubt, the faulty equipment can be switched off immediately
• A switch-off does not lead to direct follow-up problems.
Avoiding consequential damages
To avoid consequential damages in the event of failure, which could cause direct or indirect
personal or material damage, the owner must ensure that qualified personnel can assess the
faults and initiate appropriate measures to tackle them.
Protect against gas leakage from the gas-bearing channel
The Lambda Probe LS2 is fitted directly to the gas-bearing channel via the probe installation
fitting (PIF). If the Lambda Probe LS2 or the installation fitting (PIF) are removed there is a
chance that hot and/or noxious gases, which could be hazardous to health, could egress
through the open orifice in the flue - this is particularly like where the gases in the flue are at
positive pressure. A risk assessment should be carried out and precautions taken to eliminate
any hazardous situation occurring. For prevention, suitable protective measures must be tak-
en in advance.
WARNING!
Discharge of hot, corrosive gases !
In the event of high pressure and temperatures higher than 200 °C (392 °F) in the gas duct,
gas escapes when the LS2 Lambda Probe or the probe installation fitting (PIF) is removed.
Switch OFF the application before opening.
Wear protective clothing and a protective mask.
Affix appropriate warnings near by.
Close aperture immediately after finishing work.
Decommissioning/recommissioning
The Lambda Transmitter LT3 Lambda Probe LS2 are a high-quality,
electronic measuring system. It therefore requires careful handling in all situations - decom-
missioning, transport, and storage.

9
2 General Safety Instructions
NOTICE
Do not switch off the Lambda Transmitter LT3 as long as the LS2 Lambda Probe is mounted.
Not even if the associated plant has been brought to a standstill. Residual gases will cause
corrosion and could damage the probe.
Do not store the device outside without any protection!
Always store in a dry location and, if possible, keep in the original packaging.
When uninstalling, protect the ends of cables and the connectors from corrosion and soil-
ing. Corroded connectors can cause malfunctions.
If possible, always transport in the original packaging.
